Sherwin-Williams’ Loxon Conditioner is a patented acrylic formula that offers resistance to alkali; efflorescence resistance; adhesion; and fast cure time. The conditioner will bond light chalk and dusting concrete and is useful where the existing topcoat has deteriorated over time. Available in a clear or white, the pigmented version is helpful for seeing where the product has been applied on bare masonry. Fast cure time allows vertical masonry surfaces to be coated with a seven-day cure. Temperature tolerance is as low as 40 degrees.
