Gap Filling using PU Foam Spray
Insulating foam sealants or 'foam in a can' are a type of spray polyurethane foam product which are readily available with us. These products are intended for use in application for air sealing or adhering. Their small volume, ease of use, and portability make them ideal for smaller projects, such as sealing gaps and crevices.
General Tips and Safety before using Foam Spray
- Cover the floor with drop cloth or newspaper
- Foam insulation is flammable during dispensing. Remove sources of ignition, including pilot lights, until spray foam hardens completely (approximately eight hours)
- Wear safety glasses, or goggles, and gloves when spraying the foam
- Mist the area with water before and after foaming to speed up curing
- If you overfill an area, trim the excess with a serrated blade or utility knife once it has fully cured
- Fill the opening less than 50% full when applying to allow for expansion of the foam. Overfilling causes wasted product and messy cleanup
- If the foam in the straw applicator hardens, trim near the area where the foam has hardened and continue application
