Can you put asphalt sealer over concrete.

It will never cure properly on concrete. When concrete deteriorates it draws and holds moisture. They do make sealers for concrete check with you hardware store or home center. No you cannot use blacktop sealer.

It is designed to bond with asphalt. The asphalt is more porous than concrete which allows this application to work on asphalt. Asphalt sealers are specific chemical mixtures designed for asphalt penetration and top sealing. Use a squeegee or brush if needed to spread the sealant.

I have a neighbor that has a concrete pad attached to his asphalt driveway. It looked good at first but within a year most of the sealer had worn off of the concrete. Holes or cracks with depth of 2 inches or more require filling before concrete overlay is applied. It is safe to pave asphalt over concrete.

In fact many miles of concrete roads are paved over with asphalt every year. Actually probably not a good idea. 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. You can put asphalt over concrete but professionals don t advise it.

It will however require a little more maintenance than a typical asphalt overlay. Concrete is a great base material because it is stable and allows for excellent compaction of the asphalt above. Most asphalt sealers require a squeegee while most concrete sealers use a brush or sprayer. Before concrete installation begins the asphalt is inspected and repaired as needed.

A concrete stain might hold up better. 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. For most sealers pour out a line of sealant along the highest edge of the driveway. 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.

Asphalt works as a driveway base under concrete only when it is strong stable and at least 2 to 3 inches thick. Now this being said i wouldn t be afraid to try this on small area as a test.
