The Evo-Stik Expanding Foam Filler 750ml Aerosol is a high-performance, moisture-curing polyurethane foam engineered for fast and effective sealing, filling, bonding, and insulating. Designed for professional builders, contractors, and trade specialists, it provides a dependable solution for bridging awkward voids, irregular gaps, and perimeter joints around partition walls, ceilings, floors, and door frames.
 
Formulated to expand rapidly upon contact with atmospheric humidity, this single-component foam cures into a semi-rigid, closed-cell structure that flexes naturally with structural movement while delivering excellent thermal and acoustic insulation properties. It demonstrates robust adhesion to a broad spectrum of common construction substrates, including wood, brick, stone, concrete, plaster, and metal.
 
Supplied in a pressurized 750ml aerosol canister optimized for trade use, the cured matrix can be easily trimmed, cut, sanded, plastered, or painted over to seamlessly integrate with surrounding finishes. It serves as an essential, versatile consumable for general construction, gap-proofing, and thermal barrier applications on-site.
