Concrete sealers can be separated into two major types, the "wet look" and the 'dry look" sealers. The wet look or concrete film formers create a film on the concrete surface, making it look glossy and wet. They are mostly made of acrylic or rubber-based compounds. Wet look sealers create a varnished look after coating the concrete flooring. It is more affordable than dry look sealers but needs multiple re-coatings.

The other type is the dry look or penetrating sealer. This sealer penetrates the concrete and has a dry look and water repellant. Its main content is silane or siloxanes. These ingredients work to perforate pores. While it is more expensive, it has a longer lifespan.
