A non-toxic, non-flammable, water based, penetrating surface sealer that completely seals, waterproofs, and protects most materials, alkaline and non-alkaline, porous and non-porous. Effective as a sealer for stone, cured asphalt, concrete, brick, and many other surfaces. It may be applied above or below grade. Can be used alone or in conjunction with Moisture Blocker, an internal densifier and hardener that waterproofs and reduces vapor transmission. Leaves clear, non-glossy finish that will not make the surface slick. Will not alter the texture or color of the surface. Stops pitting, rusting, dust and mold from forming. Enables easier ice and snow removal.
