Interior Slate cleaning and sealing is pretty straightforward. After deep cleaning with buffers, we use commercial grade top coat sealers inside evenly applied for a fresh and protected look. Our craftsman are some of the most experienced with interior slate.
Exterior Slate cleaning and sealing is a different story. Pool water, sprinklers and direct sunlight is hard on slate. Tom has been using his formula of Densifier & enhanced penetrating sealer since 2010 with great results. The goal being to make the slate stronger and more resistant to erosion from the elements. Our service work best before the slate reaches erosion we call the “tipping point.” Proper sealing before too much erosion or when new is the best course of action to protect your slate patio.
Never, ever use a topcoat sealer on exterior slate or any stone outside. Be wary of any service provider giving performance warranties with exterior sealers.
