Can You Put Asphalt Sealer Over Concrete

Now this being said i wouldn t be afraid to try this on small area as a test.

Can you put asphalt sealer over concrete.

I have a neighbor that has a concrete pad attached to his asphalt driveway. It will never cure properly on concrete. About 15 yrs ago when he resealed the asphalt he also applied the sealer to the concrete. It is designed to bond with asphalt.

The asphalt is more porous than concrete which allows this application to work on asphalt. No you cannot use blacktop sealer. Asphalt works as a driveway base under concrete only when it is strong stable and at least 2 to 3 inches thick. It looked good at first but within a year most of the sealer had worn off of the concrete.

Only work on 2 to 4 foot sections at a time. Concrete is a great base material because it is stable and allows for excellent compaction of the asphalt above. The truth about asphalt over concrete an asphalt overlay is cheaper to install than replacing concrete and can provide a smooth ride over deteriorating concrete. Well the answer is yes.

Asphalt sealers are specific chemical mixtures designed for asphalt penetration and top sealing. When concrete deteriorates it draws and holds moisture. It will however require a little more maintenance than a typical asphalt overlay. Before concrete installation begins the asphalt is inspected and repaired as needed.

Asphalt can be successfully installed over concrete but due to the characteristics of each material you may not be happy with the long term results as the asphalt will ultimately crack in the same manner that concrete does. It s hard to beat the aesthetic appeal of an asphalt blacktop driveway but over time the material can develop spider web cracks and low spots left. Use a squeegee or brush if needed to spread the sealant. Holes or cracks with depth of 2 inches or more require filling before concrete overlay is applied.

Actually probably not a good idea. Most asphalt sealers require a squeegee while most concrete sealers use a brush or sprayer. A concrete stain might hold up better. Choosing the right asphalt driveway sealer.

They do make sealers for concrete check with you hardware store or home center. You can put asphalt over concrete but professionals don t advise it.
