It goes without saying that concrete is known for being one of the most commonly used construction materials. Construction builders use it as a foundation for countless buildings and footpaths. It costs less than other materials such as steel, and it’s easy to mix.

If constructed properly, concrete is a durable material. That does not mean that it is impervious to damage from the elements and general wear or tear. While it has the potential to last for years, it can quickly corrode or crack without the proper protection.

Why Use Concrete Sealers

A concrete sealer is important for protecting concrete surfaces from water damage, dirt, oil and other contaminants. Whether the concrete is for an indoor or outdoor application, concrete sealing products will maintain its appearance while lengthening its service life. Even if the surface begins to wear, a sealer helps restore it to its original look. Since concrete surfaces with applied sealants are less prone to damage, you save money on repair costs.

Applying a concrete sealer is a simple and straightforward process. Adhesives are usually applied using rollers when the project is small, or through sprays for industrial applications. The process is fast, and the sealants can dry within 48 hours, depending on the type.

Choosing the Right Sealer for Your Concrete

Concrete sealers are categorised into two types: topical and penetrating.

  • Topical or film-forming sealers such as epoxies, polyaspartics and urethanes are used to enhance the surface of the concrete and give it a glossy or matte finish while protecting it from the elements. They are ideal for high-traffic concrete surfaces and used in airports, industrial warehouses and retail stores. These sealers are more prone to wear, so they need to be re-applied more frequently.
  • Penetrating or impregnating sealers like silicates, silanes and siloxanes densify and increase the concrete strength. It also creates a chemical barrier around the concrete to prevent moisture and vapour transmission. They have a long lifespan and are a great choice for exterior applications since they don’t peel or wear away.

Choosing the right sealer depends on the nature of your project and the effects that you want to see on the surface’s appearance. Always check with the manufacturer to confirm the compatibility of your product with the surface you plan to apply it to.

Even though concrete is a durable construction material, it is permeable and can eventually breakdown from the elements, along with wear and tear. By sealing your concrete surface, you protect its appearance and extend its life. Just make sure you use the right sealing product for the appropriate application.
