511 SPRAY-ON GROUT SEALER 15OZ

511 spray-on grout sealer is a unique formulation designed for the protection of all types of grout both new and old. 511 spray-on grout sealer penetrates into the surface and forms an invisible barrier that is resistant to moisture and stains, while allowing vapor to escape. 511 spray-on grout sealer can be applied to freshly installed grout as quickly as 2 hrs after grouting. 511 spray-on grout sealer is UV-transparent and will not yellow under any circumstances. Due to the differences of each grout, several inconspicuous test patches should be completed to assure maximum performance.
