Stanley Pro Gap Filler - Window & Door Gap Filler - Gun Foam, 24oz

Stanley Pro Gap Filler - Window & Door Gap Filler is a single-component expanding polyurethane foam used with a spray foam gun. It features higher yield, easier application, and reusability as a window door spray foam. This polyurethane foam cures with atmospheric moisture and does not contain any propellants harmful to the ozone layer. It is ideal for both professional and DIY users, providing excellent adhesion, filling capacity, and high thermal and acoustical insulation. Perfect as a big gap filler and waterproof gap filler. Suitable for indoor and outdoor use.

How to Use

Safety Precautions: Contains Diphenylmethane-4,4'-Diisocyanate. Avoid breathing the spray/vapor. Use gloves and protective clothing in a well-ventilated area.
Surface Preparation: Clean surfaces of dust, grease, and contaminants before use. Lightly sprinkle water on the working surface.
Product Preparation: If the can is too cold or hot, bring it to room temperature. The optimal can temperature is 68°F.
Application: Put on protective gloves. Shake the can well before use. Screw the gun adapter onto the can. Hold the can upside down and activate the foam by pressing the trigger. Always handle the canister with the valve pointing downwards. Fill vertical gaps with foam starting at the bottom and moving up. Do not fill the entire gap, as the foam will expand.
Application Tips: The curing process depends on temperature and humidity; cold within 24 hours can affect seal quality. Avoid using in poorly ventilated or sunny areas. The foam may change color in sunlight; consider painting for outdoor use. Cold weather can slow curing and reduce foam yield.
Finishing: Immediately after the foam has fully hardened, protect it from UV rays by using plaster or paint. To avoid foam drying in the applicator, it is recommended to use the entire can without stopping for more than 5 minutes between sprays.
Cleaning: Use Foam Cleaner to clean fresh foam. Cured foam can only be cleaned mechanically.
