How often should you seal concrete?

How often you seal concrete depends on how quickly the previous coats get worn away. Vehicle traffic, foot traffic, and weather gradually wear away concrete sealer. Driveways usually need sealed more often than sidewalks, porches, patios, etc. A driveway should be sealed once a year to keep it looking nice and make the surface last longer. This is especially true in harsh climates where there are many freeze and thaw cycles and the concrete is exposed to road salt brought back by your vehicles. The fall is the best time to do it so it's ready to handle winter conditions.

Other exterior surfaces not subject to vehicle traffic should be sealed every two or three years. Not only does this keep the surface protected, but it also enhances the appearance of decorative concrete. As long as you seal concrete periodically, it only needs quick, thin coats. The cleaning prior to sealing is easy if you seal concrete before the previous coat wears off completely.

When it comes to interior floors, you need to seal concrete only once. After that, applying a coat of wax periodically will keep the floor protected.
