Prime Lock

Active, osmotic, penetrating material that increases the density and hardness of concrete

Product Description

Prime Lock is a unique water-based mixture of resins and ultra-fine nanoparticles that penetrates deep into concrete, expelling foreign matter, hardening, densifying and partially sealing the concrete and extending its life while protecting it from moisture.

Prime Lock is a unique water-based, non-acidic solution of blended active silicates, all of which are V.O.C. compliant. Prime Lock reacts with free lime and calcium carbonates inside concrete, producing crystalline growth within the material itself. The unique formulation of Prime Lock allows the surface of the concrete to breathe. Prime Lock is a superior hardener and dust proofer. Prime Lock will not interfere with the bond of adhesive-applied flooring materials. Prime Lock works seamlessly with our Prime Gemstone line of reactive stains and PrimeGourmet line of cementitious dyes.
