Stone Sealer Concentrate is a double-strength natural stone sealer. It contains a reactive silicone polymer in odorless mineral spirits. This impregnates marble, granite, travertine, slate and limestone, and all natural stone surfaces. It forms an invisible protective barrier on all types of interior and exterior stone surfaces. This sealer is double-strength version of Stone Sealer #1. It is designed for very porous stones or for very high-traffic areas. This sealer is solvent-based and is widely used by professionals in the stone fabricating industry. It is a low odor-safe solvent-based sealer that is very easy to use. Moreover, it can be used in many commercial applications and is also ideal for residential homeowners.
Stone Sealer Concentrate will cover approximately 500 square feet per gallon for each application. We recommend applying two coats approximately 2 hours apart rather than one thick coat. Do not over-apply the sealer and remove any excess from the surface within 5 minutes using a clean dry white cloth. The natural stone surface should be kept completely dry while the sealer is curing for 24 hours. Apply with a microfiber cloth on small areas such as countertops. However, for larger floor or wall areas apply or with a very short nap (1/8″) roller. We recommend that a single top-up application is re-applied on top of the old sealer every 2 to 3 years.
