Concrete Liquid Densifier and Hardener Products

LD 1800 is a lithium silicate concrete sealer, hardener, densifier that provides a clean, safe, economical “stand-alone” finished concrete floor. This penetrating treatment reacts chemically with the free lime in concrete to produce calcium silicate hydrate within the concrete pores, making the concrete stronger and more durable. LD 1800 is a most desirable alternative to conventional sodium or potassium sodium hardeners that leave a high concentration of salts deposited upon the surface. It will not contribute to alkali silicate reaction (ASR). LD 1800 is non-flammable, VOC compliant, environmentally safe, and non-staining. 300-400 sq ft per gallon
