As you read about graffiti removal service, you may notice that surface and substrate appear synonymous. In the construction industry, a substrate refers to the underlying surface beneath paint, sealant, or varnish. Substrate is the base for top coats and sealants. Surface refers to the surface that we can touch. When talking about pressure washing, surface and substrate have the same
definition. We treat pavers, limestone, and brick with the same processes. Stucco and concrete are harder, so we use greater PSIs. Glass and wood are different since they are fragile. With our experience, we use the perfect combinations of PSI & GPM to remove your graffiti.
