Acrylic Sealers for Concrete
For great performance at a low cost, acrylic sealers are a good choice
Available in both solvent- and water-based formulations, acrylic sealers are ideal for projects where easy application and economy are important. They can be used on both interior and exterior surfaces to form a thin, protective film that provides good protection against water and chloride intrusion while permitting moisture in the slab to escape. They are also UV resistant and non-yellowing. Available in a range of sheen levels, they also can be used to enhance the beauty of colored, stamped or exposed-aggregate concrete.
Uses for acrylic sealers include:
Acrylics are usually much thinner than polyurethane sealers and epoxy coatings, so they wear faster and usually require reapplication sooner. Solvent-based acrylics generally perform better than water-based products for outdoor use and will enhance the color better than water-based products.
On indoor surfaces, acrylic sealers usually require regular maintenance with several coats of a sacrificial floor finish, or wax, to prevent wear and black heel marks.
How to apply
Acrylic sealers can be applied by a pump-up sprayer or roller, but it's important to put them down in very thin coats to avoid fracturing. Even with two coats, the total thickness should be only about 1 to 2 mils.
