Expanding Foam Polyfilla is ideal for filling and sealing those awkward gaps, by shooting liquid foam deep into cavities, creating a long lasting seal. It insulates against heat, sound and moisture. Suitable for inside or out, it can be easily trimmed and sanded ready to be painted, filled or plastered.
