Do's And Don'ts Of Sealing An Asphalt Parking Lot

If you are in charge of an asphalt parking lot, it is highly recommend that you seal it on a regular basis. Sealing it will protect its surface and prolong its lifespan. Here are some do's and don'ts to keep in mind if you plan to seal parking lot.

Do: Pull the weeds from the cracks first

The very first thing you should do before you seal the parking lot is remove all of the weeds. If there are cracks on the surface, there are probably also weeds growing through them. Make sure you take the time to remove all of them. Try to get them from the root instead of just removing the part of the weed sticking out of the crack. This can help you clean the cracks and prevent more growth.

Do: Work from left to the right

While it may seem like working from the top to bottom is effective when sealing the asphalt, you actually want to work in rows going from thee left to the right. Side applications of sealant prevents you from stepping in the sealer as you move along. It can also improve the overall appearance of the driveway when you are done. If you still accidentally step in a portion of the parking lot that has already been sealed, repeat that section.

Don't: Forget to repair the cracks

You should never seal asphalt without first repairing all the cracks. After you have removed weeds from the large cracks, also remove any excess dirt or debris you see inside. Once cleaned out, you can apply an asphalt filler to the cracks and let it dry. If the cracks are large or deep, you can fill them with sand first until it reaches close to the top of the surface, then cover it with filler product. Make sure the filer is completely dry before you start applying the sealant.

Don't: Seal a driveway if it is a humid or wet day

All of your effort of sealing the parking lot will be wasted if you try to do it on the wrong day. You want it to be as dry of a day as possible. Check the weather forecast to ensure there is no chance of rain and that the humidity level will be low. It should also not be too hot, as that can cause the sealant to dry too quickly. A dry or cloudy day is usually good for sealing a parking lot.
