Prosoco Grind-N-Fill Liquid Crack and Gap Filler

Prosoco Grind-N-Fill Liquid Crack and Gap Filler mixes with the dust created while grinding concrete floors to create a super-durable material that automatically fills pinholes, pop-outs, and micro-cracks in the concrete surface. A surface treated with Grind-N-Fill polishes faster and easier, and accepts hardener/densifiers, protective treatments, and color more evenly.
