Sealcoating is one of the best ways to preserve your asphalt investment. This is true for driveways and parking lots. Your busy parking lot likely has to stand up to more traffic than the standard driveway. It will probably encounter and support many different kinds of vehicles, with differing weights, tires and abuse. It also directly shows your customers how well you maintain the property. A cracked, faded parking lot presents customers with a sad first impression.
The benefits of sealcoating your parking lot are numerous. Sealcoating gives your parking lot a fresh, deep black sheen that looks and acts like a newly paved lot. It presents a positive, well-maintained image of your complex. Sealcoating also helps to prevent oxidation, corrosion and staining. Because it makes your porous surface waterproof and provides protection from the sun, it prolongs the life of your parking lot. Likewise, sealcoating makes cleaning your parking lot easier because it helps fill in those pores. It protects your asphalt from pressure washing, dirt, and caustic cleaning chemicals that may be used. Additionally, it provides a cost-effective solution when it comes to preserving your asphalt. Repaving and repairs cost more than sealcoating, which will actually work to help prevent them from occurring.
Maintenance & Applications
Depending on how much use your parking lot gets and the environment it is in, experts recommend you reapply your sealcoating every two to three years. As a general rule of thumb, if you can see the individual stones of your asphalt, it is time to reseal.
Before you apply sealcoating, you should thoroughly clean your parking lot. Any repairs should be made prior to applying your sealcoating. (If you have a newly paved driveway, you should wait at least six months before sealing to allow your asphalt to properly cure) Rain should not be in the forecast for at least three days after you apply a seal coating. Parking should not occur on a newly-sealed lot for two to three days as well to ensure the sealcoating properly dries.
While an avid Do-It-Yourself owner may want to seal their parking lot himself or herself, this job may be best left to a professional. Depending on the size, sealcoating a parking lot can be a bit labor intensive. A professional may use a team of squeegee appliers, a sprayer, or a combination to ensure your parking lot is evenly finished as quickly as possible.
