$0.00 / PAIL
TK Silhard 1835 is a sodium silicate curing, hardening and sealing agent for concrete surfaces. By its reaction with the free lime and calcium carbonate in concrete, TK-1835 forms a hard mineral coating that fills the pores of the surface to maximize its density and strength. It also retains moisture in new concrete, aiding in the curing process and guaranteeing a hard, dustproof finish.
