Natural Stone Sealer for Sandstone, Patios and Internal Stone Floors

Smartseal Natural Stone Sealer is highly effective, easy to apply and safe to use. Our sealers for Natural Stone are suitable for Indian Sandstone, Limestone, Slate, Granite and Travertine. The impregnating sealers absorb into the stone, leaving the stone breathable, to prevent any moisture within the stone becoming trapped.

For optimum results and best protection, two coats of Smartseal natural stone sealer should be applied 'wet on wet' i.e. before the 1st coat has totally dried (normally 45 mins- 2 hrs). Smartseal Natural Stone Sealers are widely used in the domestic and commercial sector.  The stone sealers are suitable for sealing Indian sandstone, limestone and slate.
