Coval Stone is a professional grade sealer recommended to be applied by experienced restoration experts and coatings installers only. 

The thin film, single component coating creates an incredibly strong covalent bond with the stone. It is easily applied by hand with an applicator pad for long-lasting durability against staining. It should be installed over an appropriate surface primer, such as Coval Stone Primer or used over an existing coating.  Only available in 32 oz
