Best Penetrating Sealers

Penetrating sealers are defined as sealers that penetrate into the surface. Some penetrating sealers chemically react and remain below the surface, while other sealers penetrate in order to bond but leave behind a surface coating. This article will review the types of penetrating sealers as well as review the best penetrating sealers on the market today.

Penetrating Concrete Densifier Sealers

Concrete densifier sealers are sealers that chemically react within the pores of the concrete to create a hardened calcium silicate barrier. The barrier formed will increase the surface strength and density of the concrete. Densifier sealers are great to use on concrete if you are looking to reduce surface dusting, increase abrasion resistance, or reduce the movement of water up through the floor of the concrete.

Silicate concrete sealers will not change the look or color of the concrete. Concrete will look exactly as it did before being sealed with a silicate concrete sealer.

Penetrating Water Repellent Sealers

Water repellent sealers are sealers that chemically react within the pores of the concrete to create a water repellent barrier. They reduce water absorption by up to 95% and reduce deterioration caused by water absorption including cracking, spalling, and pitting. They also help to reduce the formation of mold, mildew, and efflorescence.

Water repellent sealers will not change the look or color of the concrete. Concrete will look exactly as it did before being sealed with a Water repellent sealers.

Penetrating Acrylic Sealers

Acrylic sealers are sealers that penetrate in order to bond, but they aren’t quite penetrating sealers because they leave behind a protective surface film. Acrylic sealers are the best penetrating sealer to use if you want complete surface protection from deterioration caused by water absorption and surface abrasion, or if you want to enhance or change the appearance of the concrete.

Acrylic sealers will darken the surface of the concrete (solvent based), or enhance with a low to high gloss finish.
