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.
Can i put asphalt sealer on concrete.
It s true that driveway sealer can t replace the liquid asphalt oil tar that oxidizes and bakes out of the mixture from heat and sun exposure.
Manufacturers claim that it is more durable and less messy than tar and many formulas contain an aggregate such as sand for greater durability.

Use a squeegee or brush if needed to spread the sealant.
Most asphalt sealers require a squeegee while most concrete sealers use a brush or sprayer.
