Xtreme Hard Concrete Densifier is a highly reactive colloidal silica-based densifying agent. The Colloidal Silica molecule has more reactive sites, so it goes to work quickly (1-2 mins). Spray it on the concrete until the surface is saturated, then agitate with a soft bristle broom. Wait until dry (45-60 mins).
New and improved Nano Technology formula penetrates deeper into the concrete. Xtreme Hard Concrete Densifier is the lowest cost concrete densifier on the market!
