Category Archives: Epoxy Sealers

Concrete may seem solid and practically impervious, but it’s porous. That’s why water absorbs so quickly into bare concrete. Left alone, this moisture causes cracks and water damage. Freeze/thaw cycles are especially hard on concrete surfaces.

Garage floors, driveways, and highways also have to deal with roadway chemicals, deicing salts, and dirt. A good concrete sealer keeps these contaminants on the surface and protects the concrete. For home and building interiors, a sealer is helpful because it prevents staining from accidental spills.

Virtually all concrete interior and exterior surfaces need to be sealed:

There are many sealer options for concrete types. Interior and exterior surfaces need different concrete sealers for the best results.

In the same way that concrete comes in countless types, including high-performance and color-stained varieties, you can also get a concrete sealer with the specific characteristics your project needs. Here are a few factors to consider:

Certain concrete sealers are designed primarily for indoor applications, and others are better for exterior surfaces. Some products are specifically formulated for the food-service industry. You can even choose epoxy-based high-gloss concrete sealers that look phenomenal in automotive showrooms.

Comprised of 100% solids and designed to be insensitive to moisture, this formulation is made from just two components. Its simplicity is matched by its versatility, with possible applications ranging from bonding for a skid-resistant overlay to patching concrete.

The longevity of concrete sealers depends on the type you choose. Penetrating concrete sealers for outdoor use can last a lifetime. Acrylic sealers need to be reapplied every 1 to 3 years with normal wear and tear. Epoxy- and polyurethane-based concrete sealers usually last 5 to 10 years without issues.
