How to Prepare a Surface for Sealcoating


Maintaining the longevity of your pavement requires routine maintenance, which includes sealcoating. Sealcoating involves applying a protective coating to the surface of the asphalt to protect it from damage caused by harsh weather conditions, UV rays, and regular use. Proper surface preparation is critical to the success of your sealcoating project. Here’s all that you need to know about how to prepare a surface for sealcoating.


1. Clean the Surface

Before commencing any sealcoating project, clean the surface of debris, dust, and dirt. Use a blower or broom to remove dirt and debris, then scrub the surface with a detergent cleaner and pressure washer. A clean surface ensures that the sealant adheres well to the pavement. Ensure that the surface is completely dry before you apply the sealant.

2. Repair Any Damages

Sealcoating covers up any surface defects, but it does not repair any existing issues. Any existing damages must be addressed before you apply the sealant. Inspect the surface for any cracks, potholes, or other areas of damage, and repair them. Patch the holes with an asphalt repair mix, and seal any cracks with a crack filler. Consider smoothing uneven areas by grinding or milling the surface.

3. Evaluate the Weather

Weather plays a significant role in the success of a sealcoating project. Avoid applying the sealant during rainy or wet seasons since moisture can interfere with the adhesion of the sealant. The ideal surface temperature should be between 50 and 85 degrees Fahrenheit. The air temperature should be above 50 degrees Fahrenheit, and no rainfall is expected for at least 24 hours after the application.

4. Apply a Primer

A primer is a layer that helps to improve the bond between the pavement and the sealant. Applying a primer extends the life of the sealcoat. Apply the primer following the manufacturer’s instructions. Stir the primer thoroughly before applying it to the surface.

5. Apply the Sealcoat

Once all the preparations are complete, apply the sealcoat. Follow the manufacturer’s instructions for mixing the sealant. Apply the sealcoat in thin layers with a squeegee, brush, or sprayer. Avoid over-applying the sealant, as this can lead to cracking and peeling. Allow the sealant to dry for at least 24 hours before allowing any vehicle traffic on the surface.



Proper surface preparation is critical to the success of any sealcoating project. By following these simple steps, you can ensure that your surface achieves optimal protection from environmental damage and long-term wear and tear.
