LD 1800 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 800 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 800 is non-flammable, VOC compliant, environmentally safe, and nonstaining.
