Most asphalt surfaces need to have a sealcoat put on to slow down the asphalt from aging. Your paving contractor can advise you about whether your parking lot or driveway needs to be seal coated, the best time of the year to have it done, and the right type of coating to use. There are a few types of asphalt coatings, and each has its own advantages and best uses. Here's a look at some options for asphalt sealcoating.
A fast-drying coal tar sealer is a good choice for a parking lot when you don't want to keep the lot taped off longer than necessary. It's often difficult to do maintenance on a parking lot if the lot is normally filled to capacity. If part of the lot is taped off for sealcoating, your employees or customers won't have any place to park.
An asphalt contractor usually does a parking lot in sections to help keep as many parking places open as possible, and using a fast-drying sealcoat makes the work go even quicker. The drawback to this type of coating is that it is expensive, so it usually isn't used for residential driveway sealing.
Acrylic sealcoating is the most expensive option, so it isn't used very often. The extra cost may be worthwhile though because the coating lasts a long time and works well. The coating even comes in different colors, so it's ideal for a tennis court or for a boutique shop that wants a colorful parking area.
Coal Tar Emulsion
Coal tar emulsion is a popular coating for parking lots, roads, and driveways. This coating isn't petroleum-based, so it protects against oil stains. Plus, this sealer is good at protecting against UV rays and rain that can cause asphalt deterioration.
A potential problem with coal tar emulsion sealers, though. is that they aren't typically environmentally friendly. Some areas have even banned their use. Your paving contractor will know if coal tar can be used in your area, and if not, they'll choose an alternative sealer.
Asphalt Emulsion Sealcoating
Asphalt emulsion coatings are sometimes used when coal tar coatings are banned. The main reason for using asphalt-based sealcoating is to restore the black color to the asphalt. Asphalt emulsion sealers can't protect the parking lot as well against stains, UV degradation, and water damage.
This sealer can only be applied during the warmer months of the year. Although it might show stains from oil and gas, this might be a good choice if you're concerned about environmental hazards on your property since it is friendlier to the environment. Discuss your concerns with a paving contractor so you know which type of sealer is best for your needs.
