The best thing about concrete driveway sealers is that it’s very easy to apply. There are several ways to add concrete sealant to your driveway and generally speaking you shouldn’t need special equipment or skills to do it yourself.
The most commonly used methods are with a roller or a sprayer. When deciding which penetrating concrete sealer is best for you, be sure to check the guidelines as it will tell you the best way to apply the concrete sealer to your driveway. It’s thought that as a general rule of thumb, water-based sealers are best applied with a roller and solvent-based sealers are best applied with a sprayer - because of the texture of the product.
It should say on the product how many square metres the product will cover, so be sure to measure the area first and buy a little extra just to be safe. Always apply thin coats and apply twice as one thick coat can not only take too long to dry but could also form uneven thick areas which are unsightly.
