Is concrete Sealer the same as polyurethane?
Polyurethanes sealers are nearly twice as thick as an acrylic sealer and form a high-build protective film on the concrete surface that provides excellent resistance to abrasion and chemicals. They can be used on both interior and exterior concrete to impart a transparent, non-yellowing, highly durable finish.

Is there a sealer for concrete?
There are two main types of concrete sealers: film-forming sealers and penetrating sealers.
