Grout-Sil is an economical water based penetrating sealer that protects grout and all natural stone surfaces (such as granite, marble, limestone, slate, and travertine) from staining. This below surface sealer leaves no sheen and is ideal for sealing all types of masonry, stucco, concrete and grout. Grout-Sil will bond to the stone and create a water and oil repellant membrane to prevent staining, yet it allows the stone to breathe and release moisture vapors. Gallon.
