One of the best things you can do for your concrete is to protect it from a harsh environment by using concrete waterproofing and sealing solutions.

Concrete waterproofing works to release trapped vapors and repel water to extend the life of your concrete. Whether the concrete is indoors or outdoors, applying a waterproofing concrete sealer to the concrete throughout its lifetime will guarantee that it lasts and always maintains it’s integrity.

Types of Concrete Waterproofing Sealers

There are several types of concrete sealers on the market. We’ll take the time to go through each one so that you understand what environments they work best in. Following that, you’ll find our list of the 7 best concrete waterproofing products on the market.

Penetrating Sealers

Penetrating sealers fill the concrete and form a chemical barrier around it. This concrete sealer soaks into the concrete to keep water out. Penetrating sealers are slightly more expensive than other types, but they also last longer.

Solvent-Based Concrete Sealers

Solvent-based concrete sealers are used almost exclusively for outdoor waterproofing concrete. This sealer will look more glossy as it drys. When it is applied, it will slowly dry, and the solvent will evaporate from the sealer.

Water-Based Concrete Sealers

Water-based solutions are similar to solvent-based solutions. One of the most significant differences is in the amount of sheen left when the product is finished drying. Solvent-based solutions tend to be more glossy, while water-based solutions are more natural-looking.

Film-Forming Concrete Sealers

Like the name implies, a layer of acrylic or epoxy protects the concrete surface giving it a high-gloss and wet finish. Unlike penetrating sealers, film-forming solutions don’t last very long at all. They form a thin protective film that deteriorates quickly. These products come in both solvent and water-based formulas.
