Concrete is a material that absorbs fluids, and this, concrete surfaces can be completely destroyed by frozen liquids expansions. Unsealed concrete can also be damaged or discolored by salt, fertilizers, oils and other chemicals that are very well used in regular household activities. Whether it is a nicely laid concrete patio or a decorative concrete pavement, you must make sure that it stays not just attractive but durable as well. Concrete sealing helps protect the concrete surfaces with several additional benefits.
You should consider durable concrete sealers when it is a long time serving concrete that you are looking for. Durable concrete sealing comes with the formation of a firm protective layer on the surface of the concrete, which creates a hard and long-lasting abrasion that is chemical resistant as well. Most of the concrete sealing is available in various colors and also tends to leave a gloss.
1. It inhibits mold: Concrete is a porous substance, which means that it can absorb water as well as moisture. Whenever this moisture is unable to dry out, mold or fungus is formed. Mold is usually formed on concrete surfaces that stay wet for a long period of time. It also creates green patches and discolorations on the concrete surface gradually. This not only protects the concrete surface but also makes it look better for a long time.
2. Extends the life for concrete: An average concrete surface lasts for about 25 to 30 years, but when there are cracks and discolorations, the concrete has to be replaced much earlier than you would plan to. Concrete sealing increases the durability of the concrete. As a result, the concrete surface may even have the durability of more than 30 years in some cases. By applying a seal on the concrete surface, potential damages are prevented from occurring.
3. Protection from exterior factors: There are several things apart from moisture, water and harsh weather conditions that can damage a concrete surface. Concrete sealing helps protect the concrete surface against oil leaks, grime, and other such stains. This also includes the UV rays of the sun. The sealant, of course, has the ability to block the moisture as well, and thus keeps the concrete surface safe from freezing or thawing.
4. Improves the concrete color: On being exposed to external elements, concrete loses its color. This sort of loss in color makes the concrete surfaces look dingy or old. Concrete sealing makes the concrete surface look sharp and clean for a long period of time.
There are different types of sealers which come with their own specific qualities and benefits:
- Sealers that are acrylic resin-based can be blended with epoxy or silicone to improve the durability of the sealer. While styrene-acrylic has low-performance qualities and may turn yellow if kept under direct sunlight, pure acrylic resin lasts much longer than that.
- Epoxy or polyurethane sealers lay a very thick layer. These products do not let the concrete “breathe” moisture.
- Penetrating concrete sealers are made of specialty resins that can penetrate into the concrete, forming a chemical barrier to water and oil, among other contaminants. These are known as penetrating sealers and are specifically suitable if you want to protect surfaces against stains.
You must remember that the type of concrete sealing that you choose determines the time of reapplication and durability of the concrete surface. The decision making is important but not a very difficult task, though everything lies in what you choose.
