A layer of sealer on top of a concrete driveway makes it easier to clean and maintain. Because it seals off pores, it keeps dirt, dust, water, and liquids at the surface, making it easier to sweep or wipe off. Owners don’t have to worry about pressure washing their driveways because water won’t get absorbed deep into the slab. Sealers also help minimize the damaging effects of deicing salts on concrete. If you are planning to use a specific cleaner, consult the installer first to make sure it won’t do more harm than good.
