PENETRATING SEALANT is a clear penetrating water and oil repellant. Penetrating Sealant provides oleophobic protection as well as water repellency making it ideal for long term protection against food, oil, and water stains. Penetrating Sealant dries clear and non-glossy and does not form a surface film. Treated surfaces retain a natural appearance, inhibits efflorescence, penetrates deeply and immediately, and is an excellent grout release. For interior or exterior use.
