$12.80 SGD

A PU based insulation foam which forms a permanent, air tight and waterproof bond to wood, metal, glass, masonry, concrete and most plastics (not on PE, PP). Excellent thermal and acoustic insulation, keeps away cold and heat, noise and humidity. Suitable for filling and insulating both indoors and outdoors and for the installation of doors and windows. Soudal Fill & Fix Foam is tack free in 20 minutes and cures in 6-8 hours. Cured Soudal Fill & Fix Foam can be sanded or painted with all ttpes of paint.
