How To Tell Your DIY Driveway Seal Coating Needs A Professional Do-Over!

Seal coating is not a DIY beginner project unless you have some seriously dedicated equipment and prior apprenticeship at a paving company. Seal coats and emulsions can be hazardous from the heated fumes they expel. Plus, there are too many errors a beginner can make in addition to putting their health at stake.

Advanced Paving & Masonry has compiled a few ways for you to determine why your DIY seal coat may need a complete teardown because of some crucial steps you missed. There is no shame in making DIY seal coating mistakes as long as one learns from them, and we are here to help you with that!

The Coat Tracks Under Your Tires & Soles

Simple. You applied too much seal coat over your asphalt and did not allow sufficient time to dry out and cure. Seal coats require at least 48 hours to cure before any surface loads can be applied, and excess will not only track under your soles, but it will dry unevenly, curing into an uneven surface.

The Seal Coat Has Pooled Up in Driveway Depressions

You didn’t patch your damaged asphalt before the seal coat, did you? Well, unlike the setting properties of a hot mix asphalt patch, a hot seal coat won’t be doing you such favors and will settle into the lowest points of your driveway in a tarry mess.

Maybe Using a Squeegee to Spread an Emulsion Was Wrong

Some seal coats are poured over the surface and spread with a squeegee. Seal coat emulsions are a category that needs specialized equipment to be constantly heated, emulsified, charged, and sprayed. If you thought heating an emulsion in a can and pouring it over your driveway would have the same effect as a typical seal coat, then you haven’t microwaved white chocolate till the point it splits. That is what will happen to your emulsion without the proper blending/heating equipment.

Used a Spray Wand and The Seal Coat Is Slipping

Before applying the seal coat, you did not clean your asphalt driveway of dirt, oils, and other debris. Dirty surfaces don’t help with surface adhesion and shorten the life of the seal coat as well as its protective properties. A wet pavement will also not allow ideal conditions to bind with a seal coat. Keep your asphalt clean.

Why Isn’t the Seal Coat Solidifying in The Cracks?

Another issue with seal coats is that people forget the layers needed. A minimum of two layers is ideal on a driveway between drying periods (not to confuse curing times) followed by the curing period. People pour too much in the hopes the thick layer will also seal existing cracks and solidify. Crack filler and crack sealers are classes apart from a seal coat and are designed explicitly for cracks.
