Residential Slate Cleaning and Sealing

Slate is a natural stone that is commonly used in home countertops and floors. Over time, dirt and grime can accumulate on your slate surface, and it can become etched or scratched. When this happens, your slate will need to be professionally cleaned and sealed, and the Sir Grout Manhattan experts are highly qualified to provide these services.

Slate comes in several different textures. There is either smooth slate or it can have a cleft (i.e. rough) finish. Slate is a porous stone and needs to be properly cleaned and sealed after installation.

The different ways to finish slate include the use of color enhancers, topical coatings (e.g. wax) penetrating sealers, and others. The type of sealer used will determine the finished look of the slate. You can achieve a gloss, matte or a low luster finish.
