VFI®-606 Acrylic Primer

Features & Benefits

• Excellent adhesion – bonds with a variety of substrates
• Distinct color options – black or dark gray helps you see where you’ve coated and where you need more coating
• Easy application and cleanup – single component can be applied in a single pass and is quickly cleaned with water
• Lower VOC compliant content – outperforms EPA standards

Instructions for Use:  

Surface Preparation 

Thorough surface preparation will depend on the substrate. The substrate should be clean and free of dirt, debris, loose paint, rust, scale or anything that may inhibit adhesion. Repair or replace damaged structural components, including ducts, gutters, flashing, and other penetrations. Gaps should be tight and flush with deflections restricted to ¼” or less by installing additional screws or rivets. Replace or tighten loose or backed-out fasteners with oversized fasteners. 

It may be necessary to power wash the surface for enhanced adhesion. Areas containing grease or oil should be scrubbed with a roof cleaning detergent. Treat mildew, fungus, or algae with a concentrated chlorine solution. Before applying VFI-606, rinse all cleaning agents from the roof and allow it to dry. 

Application 

VFI-606 Acrylic Primer should be mixed until uniform prior to use. Mix times will vary depending on volume and mixing method. It can be applied between 50°F – 120°F and the temperature must remain above 40°F while it cures. Do not apply if rain or other moisture contaminants are present. 

Apply the primer to the prepared substrate using a sprayer, roller, or brush at a minimum rate of .25 gallons per square. Cure time will vary based on temperature. VFI-606 should be top coated within 48 hours of application but must cure thoroughly before applying a roof coating. 

Cleanup 

Tools and equipment, including brushes, rollers, and airless sprayers, can be cleaned with water. Use mineral spirits or a similar cleaning solvent if the material has cured on the equipment. 

Safety 

*Always read the safety data sheet before working with chemicals  

Use chemicals only as directed and for their intended purpose. Do not dispose of chemicals down the drain. Most chemicals must be disposed of as hazardous waste.  

PPE to avoid all unnecessary exposure:  

• Eye protection – wear approved safety glasses and any additional eye protection as necessary 
• Hand protection – wear chemically resistant protective gloves (nitrile, butyl, or neoprene)
• Skin and body protection – wear suitable protective clothing
• Respiratory protection – in case of insufficient ventilation, wear suitable respiratory equipment. Respirator selection must be based on known or anticipated exposure levels, the hazards of the product, and the safe working limits of the selected respirator

Product Limitations 

As a water-based product, it must be protected from freezing. Bring the primer to a temperature of 65°F before use.  

• Incompatible materials – oxidizing agents and acids 
• Conditions to avoid – none known  
• Chemical stability – stable under normal storage and handling conditions  
• Reactivity & hazardous reactions – no dangerous reaction known under normal use 
• Hazardous decomposition products – thermal decomposition may yield oxides of carbon, aluminum, and zinc  

Potential Health Hazards  

• May cause irritation and drying of the skin.  
• May cause eye irritation with redness and tearing.     
• May cause mucous membrane and upper respiratory tract irritation if inhaled.  
• May cause gastrointestinal irritation, nausea, vomiting, and diarrhea if ingested.  

*If you are experiencing any of these symptoms, seek medical advice or attention. Call a poison control center or doctor if swallowed.
