Touch 'N Foam Max Expanding Foam Sealant, 12 oz. is a versatile triple expanding sealant designed for both interior and exterior use to effectively stop household air infiltration. This insulating foam expands to fill cracks where standard insulation falls short, creating an airtight, weather-resistant bond that not only seals out drafts but also blocks insects and pests. Made with renewable resources, it expands to approximately three times its volume, ensuring thorough coverage. The foam can be dispensed at any angle, with upside-down dispensing being the most efficient method. When applying, fill gaps no more than one-third full to allow room for expansion. The foam becomes tack- in 30 minutes, and any excess can be trimmed, sanded, caulked, or plastered within an hour. Dispensing is easy by connecting the straw to the adapter, and the can may be restarted for up to three weeks. This product is UL classified for quality and safety.
