Concrete Sealer and Water Repellent Types
Sealing concrete will protect the surface from elements, deicing salts, spills, mold/mildew infiltration, and freeze/thaw damage. Knowing this, many homeowners have elected to seal their concrete surfaces. Whether it is a driveway, sidewalk, pool deck, or patio these surfaces can benefit greatly from being sealed.
There are many concrete sealer types and it can be a bit confusing deciding which product is best for your concrete. A general description of the most common concrete sealer types will make your buying decision a little easier.Penetrating Concrete Sealers
Penetrating sealers react chemically with the concrete to shield against moisture. These sealers can dive up to a ½” into the surface and are normally used when repelling water is critical such as in horizontal surfaces. These types of concrete sealers provide excellent protection from salts, efflorescence, and freeze/thaw damage. Penetrating sealers in general do not affect the appearance of the concrete surface and are a matte finish.
Filming Concrete Sealers
Like their name suggests, filming concrete sealers form a thin protective film on the concrete surface and are typically very breathable. The most common type of film forming sealers are the acrylics. This film provides a layer of protection on top of the concrete. Filming concrete sealers can alter the appearance of the concrete. Depending on the type (water based or solvent based) the concrete may appear darker and/or have a shiny appearance.
Enhancing (Wet Look) Concrete Sealers
These types of sealers are generally used to enhance the appearance of the concrete hence their name. They form a thicker film atop the concrete than the thinner film created by the filming sealers. Enhancing concrete sealers come in a wide range of sheens. They can be glossy, semi-gloss, satin, matter, or no shine. Pigment can be added to some of these sealers if additional color is desired. The thick, durable, abrasion resistant finish repels water and provides a long lasting finish.
Gloss and “Wet Look” Concrete Sealers
These types of concrete sealers have a high percentage of solid contents. They are great for darkening brick pavers, exposed aggregate or stamped concrete surfaces. The surface darkens as if wet once the sealer is applied and it stays that way. Many homeowners like the “wet look” of this type of high gloss sealer. It can restore the original color of faded surfaces while providing adequate moisture protection.
Knowing about the most common concrete sealer types can help you in your buying decision. The most important factor is to protect your concrete with some type of quality concrete sealer to either enhance its beauty, increase longevity or both.
