Within the concrete capillary and pore structure, SCP reacts with free alkali to seal the pores and capillaries that were created by the bleedwater rising to the surface at time of pour. The reaction chemically completes, creating Calcium Silicate Hydrate, or CSH, the substance credited for giving concrete strength. SCP 327 works deep within the concrete capillary and pore structure, thereby reducing water migration levels to acceptable levels for most coatings, adhesives, and floor coverings. SCP permanently protects adhesives and flooring from failure due to high moisture content in the slab. Once SCP is installed, it is permanently a part of the concrete.
