Epoxy concrete sealers are the most durable, making them good for sealing garage floors and high-traffic retail environments. Softer acrylic sealers, which require a sacrificial floor wax, are more affordable and popular for residential concrete floors, including basements.
What is the longest lasting concrete sealer?
The longest lasting concrete sealers on the market are sodium and lithium silicate concrete sealers, like the Armor S2000 and Armor L3000 sealers. These types of sealers are designed to chemically react below the surface to form a permanent Calcium Silicate Hydrate (CSH) barrier within the pores.
How many coats of concrete sealer should I use?
two
Concrete sealers are best applied in two thin coats. The first coat of sealer acts like a primer. Most of it will disappear into the concrete surface, and the concrete will probably look fairly unattractive after the first coat. The second thin coat will provide an even finish, color enhancement and gloss.

Is it better to spray or roll concrete sealer?
“Certain sealers are better applied by spray because they are not formulated for rolling,” says Dean Owen, president of Arizona Polymer Flooring Inc. in Glendale, Ariz. “This is usually a function of the solvents used in the formulation. Slow-evaporating solvents are better for rolling.
Is it better to roll or spray concrete sealer?
