Best Sealcoating Practices: Killing Bonding Problems In Cold Blood!

Bonding problems are one of the most common issues faced by sealcoating contractors. If you’ve ever had a job where the sealcoat didn’t adhere properly, you know how frustrating it can be.

There are a few different reasons why bonding problems occur, and Action Asphalt will explain the best way to deal with each one in this blog post.

1. Pavement Defects Should Be Fixed Adequately

Over time, the asphalt pavement will develop surface defects such as traveling, potholes, or cracks. It’s essential to ensure these pavement defects are addressed before sealcoating. Otherwise, the sealcoat will not be able to bond correctly to the surface and will eventually peel off.

2. The Asphalt Should Be Thoroughly Cleaned

Any dirt or debris when the sealcoating is applied prevents proper bonding. That’s why it’s critical to clean the surface before application. A power washer is one of the best ways to clean asphalt surfaces. If you don’t have access to a power washer, you can rent one from your local hardware store.

3. Oil Spot Priming and Oil Removal

If there are oil spots on the asphalt, it’s essential to treat them before sealcoating. Otherwise, the sealcoat will not be able to bond properly and could eventually peel off. You can remove the oil spots with a solvent or prime them with an oil spot primer.

4. The Surface Should Be Properly Prepped

Once the surface is clean and the oil spots have been removed or primed, it’s time to start sealcoating. But before you do, make sure that the surface is prepped correctly. This means that all cracks and holes should be filled, and the entire surface should be smooth.

You can deal with the cracks and holes by using a crack filler or patching them with asphalt. 

5. Use The Correct Sealer

Sealers come in various types, so it’s essential to choose the right one for your needs. For example, suppose you’re sealcoating a parking lot. In that case, you’ll want to use a different type of sealer than you would use for a residential driveway.

Sealcoating material also differs when you can take your pick from coal tar, asphalt-based, acrylic, and more.

6. Use Appropriate Sealer Thickness

This is another area where many people make mistakes. If the sealer is too thin, it will not protect your asphalt as well as it should and will need to be reapplied more often. On the other hand, if it’s too thick, it can crack and peel.

Different sealers can be watered down with solvents. For instance, you can thin out coal tar sealers with mineral spirits, but you’ll need kerosene to do the same for asphalt-based sealers.

By following these six best sealcoating practices, you can extend the life of your asphalt and avoid having to replace it prematurely.
