Different Types of Concrete Stamps Require Different Materials

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-3150 and 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).
