Protect your decks! C2 Fusion is a polyurethane modified version of C2 Guard. It maintains the same non-toxic properties of C2 Guard with less than 2 grams per liter of VOC. The nano-particle resin of C2 Guard is blended with an internally cross-linked aliphatic urethane resin producing a soft sheen. Semi-transparent stains produced using C2 Fusion offer excellent UV resistance in addition to abrasion resistance.
