Penetrating Sealers are sealers that are meant to be applied to the surface of concrete, stone and other porous surfaces and create a chemical barrier to protect the surface. They do not form a ‘skin’ like a traditional finish/wax where you lay multiple layers on the surface and it creates a visible shiny coating on the surface.
Penetrating ENHANCING sealers enrich and darken the color of the surface they are applied to. They do not create a glossy or shiny surface. Other than the enhancing effect, they are invisible when applied.
