Soudal Plasterboard Adhesive Foam – Gun

Soudal Plasterboard Adhesive Foam offers a cleaner, faster alternative to traditional mortar-based dot and dab methods. This gun-grade polyurethane foam bonds plasterboard to masonry, concrete and blockwork with minimal fuss and no mixing. One 750ml canister delivers coverage equivalent to a 20kg bag of adhesive mortar, which means less carrying, less waste and considerably less back pain at the end of the day.

The foam expands on application to fill minor surface irregularities, creating a strong bond as it cures. Working time is generous enough to allow repositioning, but the rapid cure means boards stay put without temporary fixings or propping. For dry-liners and plasterers working to tight programmes, this translates directly into faster room turnaround and fewer return visits.

Why tradespeople choose foam over mortar

Traditional dot and dab has its place, but it comes with baggage literally. Mixing adhesive on site creates dust, requires water access and leaves you with buckets to clean. Foam adhesive sidesteps all of that. You attach the canister to your gun, apply beads to the board or wall, and press into position. The site stays cleaner, your van stays lighter, and your knees thank you for not lugging 20kg bags up three flights of stairs.

Consistent coverage without waste

Unlike mixed adhesive that starts setting the moment you add water, foam in the canister remains stable until dispensed. No rushing to use a batch before it goes off, no scraping hardened mortar from buckets. You use what you need, then cap the gun and save the rest for tomorrow. For smaller jobs or rooms done in stages, this flexibility makes genuine economic sense.

Soudal Plasterboard Adhesive Foam works on common substrates including brick, block, concrete and aerated concrete. The finished bond has excellent shear strength and handles the thermal movement typical in UK buildings. It is suitable for internal dry-lining applications where you need reliable adhesion without the weight and mess of wet trades.
