The main purpose of a concrete driveway sealer is to form a protective layer on the surface of the concrete. If you use a penetrating concrete sealer then the product will penetrate deep into the material to form a protective barrier. Concrete is porous and loves to hold moisture. The problem with moisture is that when it isn’t allowed to dry properly then mold and mildew can form and shorten the life of your concrete driveway. Using a concrete sealant will prevent the formation of mold and mildew and therefore increase the life of your driveway.
Another benefit to using a concrete sealer is that it will make your driveway more durable. When concrete is exposed to extreme weather such as direct sunlight, wind and rain then damage can occur such as cracking and scaling. Using a sealer can prevent this from happening and therefore save you a lot of time and energy in the future. It is thought that actually using a high quality concrete sealer can actually extend the life of your driveway by up to 30 years. Now that’s a worthy investment!
A concrete sealer will also enhance the appearance of your driveway and can greatly enhance the colours in the stone as well as adding a gloss to the surface.
