Various types of concrete sealers are available. Some of these sealers are penetrating, forming a thin barrier between the concrete and the environment. They provide invisible protection, while others penetrate the concrete to improve its durability. Penetrating concrete sealers are generally better for concrete exteriors and give a natural, matte finish. Some penetrating concrete sealers are for use on newer concrete, while others require a certain amount of time for it to dry before they can be applied.
Concrete Sealer
Before choosing a concrete sealer, ask yourself a few questions. What will the concrete surface be used for? Is it an indoor or outdoor surface? Will it be subjected to salt or direct sunlight? Will it be exposed to UV rays in the Southwest? Are you applying the sealer to a floor that is exposed to the elements? These questions will help you choose a concrete sealer that meets your project requirements and avoid any application problems.
Penetrating concrete sealers are more effective at sealing porous masonry surfaces than surface-applied products. They can penetrate a concrete surface to a certain depth but will likely form a thin film on the surface. Because silane is hydrophobic and can only be removed by the concrete, it is commonly used to seal dense concrete. Generally, however concrete tallahassee fl, silane is applied over fully cured existing concrete to provide excellent water repellence.
Decorative concrete is often coated with a decorative concrete sealer to improve its appearance. Sealers come in a variety of colors and sheens, and some are even infused with pigment.
