Macrylex Crack Sealer

methyl methacrylate resin sealer

Macrylex Crack Sealer is a 100% reactive ultra-low viscosity methyl methacrylate resin used as a penetrating sealer or to fortify extremely porous concrete substrates. Macrylex Crack Sealer is typically used on bridge decks, parking structures or as a general penetrating sealer to prevent moisture intrusion. It hardens rapidly with the addition of Macrylex Hardener, even at low temperatures.
