Frequently Asked Questions
What is an expanding foam used for?
Expanding foam fills gaps around window frames, door frames, pipes, and joints. It also provides thermal insulation and soundproofing. Both cure with moisture to fill irregular spaces.
What is the difference between hand-held and gun-grade foam?
MapePUR Universal Foam M/G offers two ways to apply it. The M version uses a hand lever with feed tube. The G version fits the MapePUR Gun Standard for controlled bead application on larger jobs. Both use the same polyurethane chemistry.
How long does expanding foam take to cure?
MapePUR skins in 10 to 15 minutes and cures in 24 hours. RLA Foam Filler skins in 8 to 10 minutes. Trim and paint after full cure.
Can expanding foam be used on concrete slabs?
Yes. Expanding foam suits concrete slab gaps, service penetrations and irregular voids. The foam expands to fill the available space and cures into a rigid filler. Check the product technical data for the gap size range.
What is structural expanding foam?
Structural expanding foam is a higher-density grade designed for load-bearing gaps and structural voids. It cures firmer than general-purpose foam and suits applications where the filler must resist compression. Check the product specification for structural use.
Is expanding foam waterproof?
Polyurethane expanding foam is water-resistant once cured. It suits wet-area penetrations and external gaps. For fully submerged or constant-water exposure, check the product technical data for the correct grade.
