After almost two years of field and independent testing, ChemMasters Inc. has introduced Silencure, a product for curing and sealing exterior concrete.
Silencure cures fresh concrete to ASTM C309 standards. It contains special silanes that penetrate concrete and seal it to the standards of NCHRP 244. Proper curing and long-term protection are accomplished in a one-time application of 150 square feet per gallon.
Silencure replaces both curing compound and silane or siloxane, and it eliminates the need for cleaners and stripping materials. Contractors who use this product will not have to wait 28 days before giving new concrete a silane treatment.
