We offer wet abrasive blasting for removal of paint and other build up on concrete and masonry. This is a viable alternative to dry sandblasting on concrete and masonry. We do not recommend this process for steel. Stripping old glue and paint from concrete porches and patios and removing built up graffiti when chemical strippers fail calls for this service. Gentler abrasives such as soda can be used on hard to clean outdoor marble.
