When it comes to the application of sealer, thicker is not better. Thick coats don’t cure evenly, are prone to tracking and can lead to surface cracks. A thicker coat takes longer to cure, which can lead to degradation and will reduce the life of your sealcoating project.
A sure sign of a driveway that has been over-sealed is a driveway without texture. An asphalt driveway should not look smooth like concrete, the asphalt texture should be visible. Applying a thick layer of sealer will not provide more protection.
Sealer manufacturers set specific mix designs for their product; when you stray from these specifications, the product will not perform as intended.
Avoid the typical more is better thinking —with sealer, thicker is not better.
