Pro Trade Expanding Foam - 750ml
Pro-Trade Expanding Foam is a triple expanding, non-shrinking, multipurpose PU foam. Expands to three times its original volume, suitable for interior and exterior use when painted. Will not shrink and reduces noise, dust and draughts. Ideal for filling large holes, cracks and gaps around pipes, skirting boards, architraves, door/window cavities. Once dry (approximately 3 hours) it can be painted, sanded, plastered, grouted, cut or caulked.
