Is there a sealer for concrete?
There are two main types of concrete sealers: film-forming sealers and penetrating sealers. Film-forming sealers include acrylics, epoxies, and urethanes that form a coating on the surface of the concrete. Film-forming sealers, especially acrylics, are more susceptible to wear and will need to be reapplied frequently.
What does xylene do to concrete sealer?
