Protective coatings are used to protect substrate from degradation by chemicals and subsequent loss of structural integrity. In construction industry that substrate is often concrete, so these materials are also used to prevent staining of concrete or to protect liquids from being contaminated by the concrete. The proper use of protective coatings is the highly effective means of preventing concrete deterioration and corrosion in water and wastewater applications. Furthermore, the coating’s effectivity depends on its degree of integrity, its ability to bond to the concrete substrate, and its ability to insulate against the passage of corrosion.
Various Types of Concrete Protective Coatings
Acrylic Sealers - Acrylic sealers work by producing a thin layer of protective film over the surface of the concrete. They are available in both solvent and water-based formulas and you can select the sheen level you desire. This type of concrete coating can be used either in the interior or exterior spaces.
Epoxy - Epoxies are a versatile option that is available in a one or two component application. Since epoxy finishes are vulnerable to UV damage, these products are normally used on interior surfaces.
Polyurethanes - Polyurethanes are also available in both solvent and water-based formulations. They can be applied inside or out and are available in a selection of sheens. Polyurethanes are almost twice as thick as acrylic sealers and produce a highly durable cover. They are ideal for high traffic areas as they provide strong resistance to heel marks, scuffs, and staining.
Penetrating Concrete Sealers - These protective coatings are commonly used to coat exterior concrete surfaces, especially those that are vulnerable to damage from harsh outdoor elements. These sealers dry to a natural matte finish, invisibly protecting the surface without changing its appearance.
Protective coatings have multiple capabilities of providing aesthetics and protecting structural concrete from weathering. They are feasible for use on all concrete elements including barrier walls, girders, abutments and wing walls and other types of foundations.
