The Benefits of a Reusable Concrete Formliner

reusable concrete formlinerLearning more about reusable concrete formliner materials may help you decide if your project can benefit from using them. These tools are used in the construction industry to mold plain concrete into decorative concrete pieces. They are a cost-effective way to mimic expensive materials, such as brick, stone, and wood, using concrete. They can be used in a variety of cast-in-place, precast, and tilt-up jobs to enhance bridges, parks, residential areas, and other architectural concrete projects.

When choosing the best form liner material, you’ll want to consider how many times you want to use it. The types of materials used to make them play a big part in their longevity. Some materials are made to withstand hundreds of pulls, but others are only good for one use.

What Is a Reusable Concrete Formliner?

What separates reusable liners from single-use ones is their ability to generate multiple pulls before they wear down. Reusable formliners are made of stronger, more durable materials that last longer as long as they are properly cared for between uses.

What Is It Made Of?

No matter what material you choose, a good way to preserve a formliner for reuse is by applying a release agent before each use to limit adhesion to the concrete. The 4 main materials used include:

1. Urethane Rubber

Among all the materials used to make concrete formliners, urethane is the best option for reuse. It is a very high-quality, durable, and flexible material that is poured over a master to create panels of various shapes and sizes. It is the only material with multi-reuse potential, as a single liner can achieve as many as 100 pulls.

Urethane is great for custom patterns with high detail and depth, custom panel sizes, and, most importantly, large projects that require high reuse. Also, when it is bonded to a plywood backing, it makes it easier to move and work with.

2. Foam

As a lightweight material, polystyrene foam is easy to use and trim to the size you desire. It can be either hot wire cut or molded to generate a smooth finish on concrete, but it is generally limited in the shapes it can create if you intend to reuse the mold more than once.

It is a decent alternative to urethane rubber, but it must be coated with a 2-part urethane encapsulant of some kind, or it will be destroyed in the stripping process after one use. For this purpose, VFI offers VFI-2538 70 D EPS Form Hard Coat, which creates a uniform and releasable surface when casting concrete. When coated, foam liners can be reused if maintained, but they will not produce nearly as many castings as urethane rubber.

3. Plastic

The number of uses you’ll get from plastic will depend on the type of plastic used and its thickness. Plastics such as styrene and ABS are used in form lining, but only ABS is capable of multiple uses (usually up to 5). While it’s more cost-effective, it won’t provide nearly as many pulls as urethane.

Plastic formliners also provide concrete with a subtle, less detailed finish since they are made using a vacuum-forming process. Plastic is a desired material if you’re working on smaller projects where only basic patterns are needed and high reuse is unnecessary.

4. Fiberglass

Concrete formliners were once made of fiberglass sheets fastened to a form to create basic ribbed patterns. As new materials and techniques emerged, fiberglass took a backseat in the industry since it was much more time-consuming to use. Urethane rubber is easier to work with and produces results just as good in most applications. If more than 3 inches of relief is needed, fiberglass is preferred, though urethane is capable of high reliefs as well.

Benefits of Urethane Rubber

  • Cost efficiency – While urethane rubber is a more costly material, its reuse potential more than makes up for the initial cost. With proper cleaning and storage, you’ll be able to maximize the life of your reusable concrete formliner.
  • Durability – Most urethane formliners are made of solid rubber, so they have the strength to endure multiple pulls. The best reusable ones use higher durometer urethanes, typically between 70A – 90A. The harder the material, the more capable it is of maintaining its strength over time.
  • Flexibility – Urethane can be more flexible or rigid depending on what kind of incuts you require in the design of your formliner. This increases the design potential you have while the material maintains its reusable nature.
  • Versatility – Unlike other materials, urethane can copy extreme detail from a master and transfer those details onto wet concrete. You’re then left with concrete pieces that have the realistic finish you desire. There’s no limit to the concrete textures, patterns, or designs you can create with urethane. It is also capable of creating reusable concrete formliners of any shape or size needed.
  • Consistency – Because urethane concrete formliners have such high reuse potential, they produce repeatable, uniform patterns after each use. Urethane reflects the same amount of detail in every cast, so large projects are desirable and seamless.

VFI Urethane Rubbers

VFI manufactures various urethane rubbers for the creation of reusable concrete formliners. Depending on the detail desired, we generally recommend the 50A-90A rubbers in our 2100 series. Our VFI-3170 and VFI-3180 rubbers are also excellent materials but must be used in controlled, high-production environments.

Why Polyurethane Formliners Are the Best for Concrete Projects

Posted on: September 11th, 2023 by mandig

Why Polyurethane Formliners Are the Best for Concrete Projects

reusable urethane formliner Unlike traditional materials such as plastic or foam, polyurethane formliners offer a unique blend of qualities that make them the superior choice for concrete projects. One of urethane’s most remarkable characteristics is its flexibility. Due to its flexible nature, it can replicate complex patterns and intricate designs, including incuts, curves, and irregular shapes. It has unlimited design potential for replicating natural materials, pushing boundaries with abstract patterns, and even incorporating logos into architecture.

Other, more rigid materials can’t achieve the same highly realistic detail and definition on concrete surfaces. Urethane is also much more durable than any other material. With its resistance to abrasion, chemicals, and excessive wear, a single liner withstands multiple uses.

How are Urethane Formliners Made and Used?

Polyurethane formliners are made of a high quality, two-component material that combines isocyanate and polyol, which forms a liquid rubber that is poured into a mold and over a master. The liquid flows into all voids and contours every line to pick up every minor detail, including the porous nature of rocks, creating a perfect replica. Urethane cures at room temperature and comes in a range of hardnesses to fit a variety of application needs.

Before casting concrete into the new mold, it’s recommended that an acceptable release agent be used on the face, edges, and ends before each cast. Do not over-apply, as this may create pooling in the mold that will cause surface voids or bug holes. These voids prevent the concrete from copying all the details from the urethane.

The formliners are generally placed inside formwork before the concrete is poured. They must be properly aligned and secured for the best results. Large liners are usually attached to plywood backing since they weigh more and are less flexible. Plywood allows for attachment points in order to pick up the liners with machinery for precise placement and increased size. Using larger liners this way also allows for a quicker set-up and application on larger projects.

Once the concrete hardens, the formliner is removed, and all the details are transferred onto the surface. Urethane’s elasticity simplifies the stripping process, allowing it to easily release from intricate details and undercuts in the concrete for damage-free demolding. These formliners can also be inverted to generate different, less predictable patterns on the concrete. When using urethane, it’s much easier to avoid noticeable seams in the design as well, especially if you’re using large panels of the material. When plastic is used, more effort goes into making larger forms, as an adhesive must be used to glue several pieces together.

Where Are They Used?

Polyurethane form liners see the most use in large projects and areas with a lot of square footage to cover. If you need long spans or a seamless appearance in the concrete, urethane is the best option capable of fulfilling these requirements. It is a cost effective choice for any project that requires a high number of reuses.

Urethane is the best material for producing high detail and relief for projects, especially when a certain level of realism is needed. There’s almost no limit to where urethane can be used, including tilt-up, cast-in-place, and precast applications. Other instances where urethane makes a great form lining material include:

  • Architectural facades. Add depth and character to flat, plain concrete surfaces on the exterior of buildings and give them a new identity.
  • Landscaping. Craft inviting outdoor spaces such as charming pathways with natural rock formations in retaining walls to connect with surrounding landscapes.
  • Interior design. Enhance plain walls and columns and turn them into a stunning focal point for indoor spaces such as hotels, residences, and shopping centers.
  • Infrastructure. Beautify utilitarian structures such as bridges, tunnels, and public spaces with artistic, textured elements.

How to Take Care of Your Formliners

A urethane formliner’s reusability will depend on how it’s used, how it’s cared for, how detailed it is, and the job site conditions. Key steps to preserve the life and quality of the liners include:

  • A release agent should be applied before each use for easier demolding and to prolong the life of the liner. Cleaning the release agent off after use is also essential, as some release agents can be reactive and degrade the material over time.
  • A clean liner will last longer and produce excellent results each time. Proper cleaning after each use removes concrete dust and buildup, preventing debris from affecting the detail of subsequent pours. Clean with hot water, soap, and a natural bristle brush. Never use a wire brush or harsh chemicals that might damage the urethane.
  • Be careful and gently pry the formliner from the concrete in the stripping process. Peeling it back can create additional stress, reducing its usefulness over time.
  • The form should be removed within 24 hours after the concrete has cured, or stripping may be difficult. While urethane is durable, you want demolding to be easy to keep the detail intact.
  • Proper storage is also required to maintain its usability. Store it flat and in a clean, temperature-controlled environment. Do not let it sit face up in the sun for long durations of time. UV rays deteriorate urethane and may cause it to expand and fall apart.

Six Benefits of Precast Concrete Products

Posted on: May 18th, 2020 by Marc

Six Benefits of Precast Concrete Products

precast concreteThe construction industry is becoming increasingly reliant on precast concrete products. According to Verified Market Research, the precast concrete market “is projected to reach $178.75 billion by 2028, growing at a CAGR of 5.56% from 2021 to 2028.” This growth is expected to occur from rapid urbanization and industrialization, increasing investment in new construction projects, and infrastructure development.

Precast concrete is a form of concrete that is cast in a well-controlled environment or precast plant. This means the concrete is cast and cured before it is transported to the work site for installation. The concrete mix varies based on desired strength, colors, and performance features. If additional strength is required of the concrete structure, it can be reinforced by adding rebar or steel cable.

Typically, the concrete is cast into flexible, reusable molds or forms. Urethane rubber molds are highly customizable precast concrete products. The rubber comes in different hardnesses with various pot life options based on your processing needs. A wide variety of architectural and structural elements can be made with this material, including stone veneer, panels, hardscape, stamped concrete, and more.

Why Use Urethane Rubber for Precast Projects

1. Versatility

When urethane rubber is used, you can replicate concrete pieces of virtually any size, shape, or detail to fit your project requirements. It can be used in the field or in a factory setting. The molds are not limited in their design as they can be made with various curves, bends, angles, and odd designs. They also offer a variety of textures and finishes to choose from.

Making custom forms allows even the largest-scale construction projects to have unique elements. From schools and hospitals to bridges and parking garages, there’s almost no precast structure that urethane can’t be used for. These molds and form liners are great for architectural concrete, cast stone, highway barriers, retaining walls, and more.

2. Aesthetics

Precast concrete can be more than just functional; it can also be desired for its increased decorative purposes. Urethane molds and forms have been used to produce precast concrete for some of the most aesthetically pleasing buildings and structures. When the molds are made, they copy the intricate details and designs of a master and transfer those details to the concrete. The concrete can easily mimic the look of historical stone or brick for a fraction of the cost.

Other molds made from plastics, wood, or metals can’t offer the same elaborate patterns as urethane. If you’re looking for intricate and noticeable designs, the rubber will provide the high level of precision and advanced detail you desire.

3. Repeatability

Urethane forms are considered some of the finest and most durable products on the market. Their durability allows them to be used over and over to create copies of the same design, ensuring consistency in your precast concrete project.
These reusable molds can produce up to 100 castings before they lose detail and strength. High reusability and repeatability also mean you get the same level of detail in each cast until the mold needs to be replaced.

Concrete molds made of wood or plastics only get between 1-10 uses. While steel molds can produce more, they are limited in the designs that can be created. It is also cost-prohibitive to produce or to have more than one of them.

4. Cost-effective

Casting concrete in urethane molds is much more cost-effective than using natural building materials such as stone, brick, and other masonry. Since it is such a durable, long-lasting material, you save money by not having to replace your molds as much.

Urethane forms are also compatible with high-end applications, so you can make durable concrete that withstands impact, corrosion, and acid attack. Not only do your molds last a long time, so do your concrete structures.

5. Quality Control

Depending on the type of urethane rubber chosen, the material can be time and environmentally sensitive, which means it must be poured and cured under specific conditions. Because the precast process is done in a well-controlled environment, it’s the perfect place to use urethane.

Quality assurance technicians are able to assess the entire process, from making the molds to mixing, pouring, and demolding the concrete. Since the precast concrete products are tested and reviewed during each step, you’re left with superior quality and a more consistent product. In this setting, the concrete is also allowed to strengthen before it is transported to the work site.

6. Convenience

Since the forms and molds don’t need to be set up on-site, precast concrete reduces construction time and lowers labor costs as well. Molding concrete off-site also reduces the equipment and labor needed on-site. Workers can carry out other projects while the concrete is made to prevent construction delays.

Determining Shore Hardness of Rubbers & Plastics

Posted on: May 18th, 2020 by Marc

Shore Hardness is the resistance a material has to indentation. Determining a materials Shore Hardness requires the use of a durometer, which is a device that measures the depth of an indentation in the material by creating force through a presser foot.

In order for people to have a point of reference on how hard a material is different shore hardness scales have been created. There are 12 different Shore Hardness scales depending on the type of material that is being measured.

When dealing with rubbers and plastics two scales are used. The A Shore Hardness scale is used to measure flexible rubbers commonly used in molds. Hard rubbers, semi-rigid plastics and hard plastics are measured using the D Shore Hardness Scale.

Both of these scales have ranges from 0-100. The lower the Shore Hardness is on the scale the softer and more flexible the material will be. As you increase upwards on the scale materials become stiffer and less flexible.

When selecting a rubber or plastic to use for your mold making needs there are a couple of things that should be taken into consideration.

How delicate is the item that you’re molding. 

If you’re making a mold of an item that has sharp undercuts, thin parts or protrusions it is recommended to use a material that provides greater flexibility and stretches easily. This will insure that you’re able to extract your model from the mold without it breaking.

How much detail is needed for your project.

When using rubbers and plastics detail is directly related to the hardness of the material that you’re using. The harder a material is the greater casting detail it will provide. For example, if you were making a mold for a stone back splash you would want to use a harder material to pick up textural detail within the rocks.

Abrasion Resistance

Abrasion resistance refers to a materials ability to withstand any method of wearing down or rubbing away by means of friction. This point should be taken into consideration if you are planning to use a rubber or plastic mold for construction applications. Some of these application would include architectural precast concrete, cast veneer and flexible form liners. In construction applications you want your material to provide enough flexibility, while being durable and insuring a long useful life.

Different Types of Concrete Stamps Require Different Materials

Posted on: May 18th, 2020 by Marc

Concrete stamps can take a basic concrete project and bring it to the next level. These stamps are used to enhance a surface and make it look decorative by providing a textured detail imitating stone, brick, wood and much more. They are most often used to create decorative walkways, courtyards, patios, decks and on decorative vertical concrete applications.

Most stamps are made out of urethane rubbers as this material provides a range of Shore Hardness options, while remaining flexible and providing maximum abrasion resistance.

Producing stamps can be expensive, that’s why it’s important to understand how to pick the correct rubber for your needs. Stamps come in numerous types and flexibilities ranging from floppy to rigid. Three common types of stamps are stamp rollers, texturing skins and concrete mats.

Stamp rollers are used as imprinting tools on large scale projects, on slab corners and boarders where detail is not as critical. These stamps are popular with contractors because of their ease of use and can cover a lot of ground quickly.

It’s important to have an understanding of what to look for in regards to the type of rubber your stamp roller is made out of. Rollers work best when the concrete is still very soft. Because of the roller application, a harder durometer rubber is needed to imprint detail quickly. VFI would recommend our 3170 or 3180, for this application. This will help to insure maximum detail will be transferred to your project’s surface.

Texturing skins are used in vertical and decorative applications where flexibility would be necessary. These stamps are usually thin to reduce weight and make them more maneuverable on the job-site. Semi-rigid rubbers are used to allow the stamp to be more pliable and capture the curvature of a structure. These skins work best on surfaces with undulations, sloped areas and in flare ups like driveway aprons. VFI-3160 provide the perfect amount of flexibility for challenging applications while still providing great casting detail.

Concrete mats are rigid and extremely firm. These mats are very large, and most of the time will have handles to help contractors lift and move them into place. The rigidity of concrete mats will help to leave a highly detailed impression. The polyurethane used in these stamps will range from a Shore A Hardness of 80 or higher (VFI-3180). Interested in making your own concrete stamps? VFI has Technical Service Representatives willing to answer all of your stamping questions. Contact the VFI team at 1-800-307-9218.

What Is Silicone Roof Coating?

Posted on: January 4th, 2020 by Marc

What Is Silicone Roof Coating?

what is silicone roof coating

Silicone can be used as a liquid applied roof coating to provide waterproof characteristics and UV stability. Roof substrates of all kinds break down over time and eventually cause roof leaks. These leaks typically cause expensive damage to the building itself, as well as the contents of the building.

As roof substrates age they eventually begin to fail. When this happens, a building owner has three obvious options:

  • Repair the leaks. Repairing leaks can be very challenging. The source of the leak is often very difficult to find and the repair is simply a band-aid approach that offers a short-term solution.
  • Roof replacement. Not only are roof replacements very costly, but the material from the original roof ends up in a landfill. Many building owners are looking for more ecofriendly solutions to the maintenance of their buildings.
  • Maintenance coating. Using silicone as a maintenance coating is a way to offer a long-term solution while being much more cost efficient, and ecofriendly, than a full roof replacement. When done properly, a silicone roof coating offers a new layer of protection that can last for years.

Why does silicone work as a roof coating?

The benefit of silicone as a roof coating comes from its non-carbon nature. Silicone is inherently resistant to bacteria growth and resists degradation from ponding water while still providing breathability for the substrate. This breathability helps to protect the substrate which leads to a longer lifespan.

When is it best to use silicone?

Silicone is used when there are concerns associated with UV stability. Silicone is naturally resistant to ultraviolet rays which cause oxidation and can reduce the life of a roofing substrate. Another benefit of silicone is its ability to withstand indefinite exposure to ponding water. Proper drainage is always necessary on a low slope roof, but the risk of standing water still exists. A silicone roof coating provides a waterproof barrier that protects the roofing structure, which in turn helps to expand the lifespan. And since silicone is resistant to mold and mildew, dirt and grime build-ups can easily be washed off with water.

What are the best silicone products and why?

There are three main types of silicone for the liquid applied roofing industry:

  • High Solids Silicone is the most used silicone roof coating. With the ability to apply by spray, roller, or brush, it offers lower VOC, a glossy finish, and decreased application time due to higher volume solids.
  • Standard Solids Silicone has a higher VOC content, but gives better adhesion and a smoother finish with less roller marks and brush strokes. A lower solid content does mean a lower volume solid, but with the increased adhesion this is the preferred product for recoating other silicone.
  • Silicone Flashing Grade is an extremely thick silicone that is used for flashing or seams when combined with fabric. A high solids content in the mastic allows for minimal shrinkage while maintaining excellent adhesion and flexibility. Adhesion and flexibility are important because they allow the flashing grade to move without cracking and remain fixed to the surface.

How is silicone applied?

Silicone is extremely easy to apply. The first installation method is by brush. This is normally for silicone flashing grade or for application over seams in combination with fabric. The second method is roller applied. Roof silicone is compatible with almost all roof roller types. The third method is spray applied and is usually done with a high-pressure spray rig.

Silicone plays a large role in liquid applied roofing. The advantages as a maintenance coating far outweigh costly roof replacements. The properties of silicone are superior to other fluid applied products like acrylic. And more roofing contractors are realizing the benefit of offering application services to commercial building owners. The choice is simple.

Commercial Roof Coatings: Silicone vs. Acrylic

Posted on: January 4th, 2020 by Marc

Commercial Roof Coatings: Silicone vs. Acrylic

Commercial Roof Coatings Silicone vs Acrylic

What type of commercial roof coating should you choose for your property? The biggest debate for many facility owners and managers seems to be whether they should select silicone or acrylic. What differences exist between these two options, and which one is the best solution? The problem with choosing which one is the “greatest” is that what’s best can vary from one roof and customer to the next.

You see, there are advantages and disadvantages to each of the options. Therefore, you will want to have an overview of each of these types of liquid applied roof coatings. This can allow you to choose the most suitable option for your needs. Begin with the basics.

Silicone Roof Coating

Silicone roof coatings have been around since the 1970s, and they were often used as part of spray polyurethane foam applications. As time progressed, they eventually became a good option for coating a wide range of roofing substrates including metal, built-up roofs, concrete, and more. They are common for commercial roof restoration. Silicone coating is resistant to ponding water, and it provides fantastic UV stability.

Acrylic Roof Coating

Acrylic roof coatings have existed longer than silicone, and they have been a popular option for commercial roof restoration for decades. The products can work well with a range of roofing substrates, just like silicone. These coatings are UV resistant, environmentally friendly, and are simple to work with and clean up. Acrylic coatings work well for many substrates, as mentioned, but they tend to be best-suited for sloped metal roofs, where ponding won’t be a problem.

A Closer Look at Commercial Roof Coatings

Let’s get a closer look at how these two types of products compare across a range of different factors. Understanding the differences between the products and seeing where each excels can help provide you with the information required to make an informed decision.

  • Comparing the Costs

Naturally, finances remain a concern for all business owners who are in need of a commercial roof coating. You want to get great results, but you also want to ensure you are staying within your budget. Simply put, customers attempting to save money will want to opt for acrylic if all other factors are equal. This is because acrylic roof coatings are a more affordable option.

  • Resistance to Ponding

Ponding water causes issues with flat commercial roofs, as it could mean eventual leaks. This is one of the areas where acrylic coatings have a weakness. Acrylic doesn’t hold up to ponding water nearly as readily as a silicone roof coating can do. Therefore, if you have a flat roof where ponding water could potentially become an issue, opting for silicone is the better solution.

  • Application of the Roofing Product

One of the reasons some consumers prefer silicone is because the application can be thick on the first pass. Business owners might find that they need only a single application for their roof, which could be beneficial. However, when compared with acrylic roof coatings, despite needing a second coat in many cases, silicone is simply messier, making the application of the product more difficult. If spraying the material, it requires heavy-duty machines that might not be readily available for some contractors.

On the other hand, acrylic coating applications are speedier and easier in most cases. This remains true whether the material is rolled on or sprayed onto the roof. Cleanup tends to be simpler with acrylic coatings, as well. Still, it does mean that there will need to be more than just one coat.

  • Longevity and Durability

Another commonly asked question when comparing silicone and acrylic commercial roof coating materials is which will last longer and be more durable. It’s important to keep in mind that countless factors will affect the longevity of the products. However, silicone roof coatings typically last longer than acrylics. Although both can safeguard from ultraviolet rays, silicone offers greater protection. As mentioned, it also provides better moisture resistance when dealing with problems like ponding water.

As for durability, silicone does tend to be more durable over time. Because of the longevity and durability advantage that silicone has over acrylic, it could make up for the price difference between the two. Of course, you’ll want to keep in mind that acrylic roof coatings are no slouch when it comes to longevity. When applied correctly, they can last for a decade or more without trouble.

  • Thermal Reflectivity

Have you considered the thermal reflectivity of the roof coatings? Thermal reflectivity can affect how hot the roof gets and the temperature inside the building. You’ll find that both of these options can provide thermal resistance between 80% and 90%. They can both perform quite well in this regard, helping to keep it cooler inside the building. This can reduce the amount spent on keeping the building cool during hot summer months.

Of course, you’ll want to consider that silicone roofs can pick attract small amounts of dirt over time, but this doesn’t reduce the thermal reflectivity. With that said, acrylic coatings could be better in this regard since they tend to stay cleaner longer.

  • Are Commercial Roof Coatings Environmentally Friendly?

What about environmental friendliness? Which of the coatings is a better option? In the past, acrylic was the hands-down choice because it’s water-based and doesn’t have the same level of volatile organic compounds typically found with silicone. However, some of the newer silicone products on the market have low levels of volatile organic compounds, making them far more environmentally friendly than they were in the past. This is particularly true with some of the high-solids silicone coatings available today.

  • Which Looks Better?

The aesthetics of the commercial roof coating are up to you. They have a similar appearance, so the looks are not likely to be a factor in most cases. However, if you have a sloped roof on your commercial property, which is visible, you might have a preference. Acrylic roof coatings tend to have a cleaner overall appearance and they do work well for roofs with slopes. However, acrylic may fade or color shift over time. If you have a flat roof, it’s important to use silicone for its waterproof properties regardless of your viewing angle.

How Long Does Silicone Roof Coating Last?

Posted on: January 2nd, 2020 by Marc

How Long Does Silicone Roof Coating Last?

how long does silicone roof coating last

When contemplating whether you should get a silicone roof coating for your commercial property, one of the biggest questions that’s likely to come up is how long it will last. After all, you want to make sure you have a roof coating that is durable and can withstand the test of time. You don’t want to have to replace the coating in two or three years.

The answer to this question can vary based on the thickness of the coating and how well you take care of the roof. Typically, moisture cure silicone roof coatings can last for about 15 years. This tends to be the average. This requires that you ensure the roof is properly cared for during that time.

The thickness of the coating will affect how long it can last. When the coating is applied at 1.5 gal/sq (20 dry mil thickness), most roofing companies will provide a 10-year material warranty. When the thickness level is increased to 2 gal/sq (32 dry mil thickness), the warranty will generally be for about 15 years. This is because the thicker coating can provide added protection.

The length of the warranty can vary based on the company you choose to apply the roofing. Naturally, you will want to check with them about their warranties before hiring them.

How to Make the Silicone Roof Coating Last Longer

If you choose quality elastomeric roof coatings for your business, you want to make sure they can last for as long as possible. You should work with a professional to provide you with the proper annual maintenance for your roof. They can let you know whether any issues need to be addressed in certain areas. Additionally, it is in your best interest to have a roof inspection after any serious weather events that could have impacted your roof surface.

The amount of foot traffic that takes place on the silicone coating could affect the longevity of the coating, as well. Therefore, if you have a roof that may see a lot of foot traffic, you should use a high-quality walk-pad capable of standing up to the use.

Remember the importance of maintenance to longevity. You or your employees can handle some of the maintenance on your own, such as hosing down the roof once a year. However, anything that goes beyond the basic maintenance of cleaning the roof should be done by a roofing contractor.

The contractor can check the roof for any signs of damage and ensure that there is no ponding water that could somehow cause a leak or show signs of a problem beneath the coating.

While silicone roof coatings are excellent at preventing leaks, if something causes damage to the coating, there is a small risk it could still allow for water to get into the building below. Scheduling an inspection annually is a good way to make sure that any potential issues are caught as soon as possible. This will help to make the repairs easier and more affordable.

If you have leaks on your existing roof, you should work with roofing companies to have those leaks repaired before you apply the coating. This helps to improve the integrity of the roof. Additionally, keep in mind that this type of coating is for low sloped roofs rather than high sloped roofs.

Let the Professionals Add the Silicone Roof Coating

If you need a new liquid applied roofing system for your commercial property with a flat roof, be sure to work with professional roofing contractors. The professionals are qualified applicators and have the tools and materials needed to coat a roof properly and quickly. Although there might be the temptation to do it on your own, it can be a lot of work, and you will need to have specialized equipment and experience to do it right.

Often, it will be easier to work with roofing companies. They know how to prepare the roof, add the coating, and make sure it is done correctly.

Is a Silicone Roof Coating Worth It?

Do you have a commercial property that needs a new roof? Having a roof that can last for years and that will need minimal maintenance is important. You may be considering getting a silicone roof coating, but you still aren’t sure whether it is the right choice or not. Is a silicone roof coating worth it? Before making a decision, you should examine some of the main benefits that come from using this type of roofing. It can give you a better idea of whether a silicone roof coating is worth it for you.

The Roof Can Last a Long Time

One of the first questions that people tend to ask regarding different roofing systems is how long they will last. Typically, a silicone roof coating will last about 15 years. In most cases, it could last longer. Of course, it may last less time than this if it is not cared for properly. The better you take care of your roof the longer it can last. This means you won’t have to worry about your commercial roof surface for many years.

Maintenance Is Easy

You will also find that the maintenance of the roof tends to be easy. Most of the time, simply sweeping and hosing down the roof once a year is all you’ll need to do. You could handle this on your own, or you might want to use a roofing contractor for the job. The contractor can also look for any other potential issues that might arise with the roof surface. You can then take care of the roof repairs before the problems get worse.

Easy Installation

Another nice benefit of high solids silicone roofing that makes it worth your time and money is the ease of installation. In some cases, you might not even need to have a primer placed on the roof before the coating is applied. The coatings can be rolled on or sprayed on in most cases. Business owners can apply the coating on their own, as long as they have the tools, the material, and the time. However, it’s generally a better solution to work with a professional roofing contractor to handle it. This ensures that the coating is applied correctly and in less time.

Cures in the Outdoors

Silicone roofing systems will cure in the outdoors without the need for any special preparations. Once the coating is applied, it will start to cure quickly. The heat and moisture in the air can help it cure properly. The amount of time it takes to cure can vary based on the thickness used and the weather. Your roofing contractors can give you a better idea of how long it will take to cure before there can be foot traffic on the roof.

Protects from Leaks and Ponding Water

Flat and low sloped roofs that are often found on commercial properties will often have ponding water problems. This means that the water that hits the roof after rain finds a location to settle and sit. This could eventually cause leaks in the roof if you aren’t using a silicone roof coating. These types of coatings provide an ample amount of protection against the problem of ponding by holding it until it evaporates or drains properly.

If you don’t have one of these types of roof coatings, you will need to have someone remove the standing water each time it rains. A good silicone coating can help you save a lot of money on labor, as well as repair expenses.

Reduce Energy Expenses

This is one of the benefits that many people never even consider. The silicone coatings on commercial roofs will be white and reflective. This provides you with a “cool roof”, which means it can reflect much of the light that hits it. You will not have to use your air conditioning in the business as much because it will stay cooler.

Choose Quality Silicone Roof Coating Material

As you can see from the benefits discussed above, a silicone roof could be a fantastic idea for your commercial roof. Keep in mind that high solids silicone is the preferred maintenance material for flat and low sloped commercial roofs. Additionally, you have to make sure you are using the best silicone coatings for the job.
