Concrete is like a sponge, it absorbs water and holds it. When winter comes the absorbed water expands under freezing temperatures. This can destroy the surface of the concrete. Installing a sealer not only limits water absorption, it also limits staining from oils and salts.
Concrete sealers can extend the life of your driveway as well as keep it looking great for years. However, it is important to pick the right product and ensure its installed correctly.
This week we are reviewing different types of sealers.
The most common types of film-forming driveway sealers are acrylic-resin based. Acrylic sealers provide the best performance characteristics for the cost, and they often are blended with epoxies, polyurethanes or silicones to improve performance, durability and water resistance. Acrylics, themselves, are also available in different forms, with some types delivering better performance than others. Styrene acrylic, for example, is a lower-performance acrylic resin that may yellow and degrade when exposed to direct sunlight. The best type of acrylic is a virgin or pure acrylic resin. These sealers will last longer than styrene acrylics, with no yellowing.
