A concrete stain might hold up better.

Can you put asphalt sealer on concrete.

Sealing asphalt or concrete helps it last longer and look better while you put off the inevitable replacement. I have a neighbor that has a concrete pad attached to his asphalt driveway. Only work on 2 to 4 foot sections at a time. It looked good at first but within a year most of the sealer had worn off of the concrete.

Actually probably not a good idea. Asphalt sealers are specific chemical mixtures designed for asphalt penetration and top sealing. The most common type of concrete sealer penetrating sealer should not be applied before new concrete is completely cured at least 28 days. A single application can last from.

Asphalt sealers aren t intended for use on concrete. Most asphalt sealers require a squeegee while most concrete sealers use a brush or sprayer. You can use blacktop sealer on concrete it will cure properly and will not track up the only problem you will have if your concrete is already breaking up it will continue to do so because there is. When cracks appear in a driveway and they always appear in a driveway moisture gets down into the paving and wreaks havoc.

The main enemy of any driveway is moisture. You can put asphalt over concrete but professionals don t advise it. For most sealers pour out a line of sealant along the highest edge of the driveway. It erodes the base below the surface leading to settling and holes.

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. Use a squeegee or brush if needed to spread the sealant. The asphalt is more porous than concrete which allows this application to work on asphalt. About 15 yrs ago when he resealed the asphalt he also applied the sealer to the concrete.

You can also mill or grind the concrete prior to the overlay to ensure the new asphalt overlay will have a good bond to the concrete. Check the label to make sure you re using the right sealant for your job. For example different types of asphalt fabric can be installed to reduce the amount of reflective cracking that can occur in an asphalt overlay on concrete.
