It is a process very similar to house painting. Your asphalt driveway may become weak due to sun exposure, oil spills or heavy traffic. The process of seal coating includes applying a coal tar emulsion or asphalt to help protect it from these damaging elements.
Sealcoating acts as a protective shield and covers surface voids. When you seal coat your driveway the exposure to UV rays and oxygen reduces the possibility of gas or oil penetrating your asphalt. It is also a great waterproofing material.
Sealcoating should be done at temperatures starting at 10 degrees Celsius and rising. When done in colder temperatures than this, the seal coat may not adhere to the asphalt properly.
Sealcoating should be done every 3 – 5 years depending on weather conditions and the amount of use your asphalt surface gets.
During the warmer months the drying time can take 3 hours or less and 8 hours or more during the cooler months.
This is a very effective method of maintaining your asphalt product since it slows down the effects of UV light, oxidation, and provides a barrier against petroleum and other harmful elements.
It is recommended that you wait for a minimum of 1 – 2 days before using the driveway. This may decrease or increase depending on the weather and the amount of shade that is covering your driveway.
Besides repairs and any crack filling, the surface will need to be clean and free of oils. We will eradicate weeds, but the client will be responsible for edging lawns, borders, etc.
The sealcoating material takes time to cure. As this is the case, tire marks would sometimes appear after it has been applied. This normally disappears after 1 to 2 weeks once it completely cures.
Sealcoating is best done during the summer months. However, the spring and fall often have days warm enough for seal coating.
Definitely. Proper crack repair conducted may double the life of your pavement.
It is best to have them sealed immediately. If left unsealed, moisture will penetrate, weakening the pavement and the sub-base causing further deterioration in the asphalt.
We should remember that seal coating is a cosmetic process and not a way of structural repair. If your payment requires crack sealing or patching, these should be done prior to seal coating.
Once completed, your asphalt will have a uniform black color. The change is quite dramatic, and curb appeal skyrockets (without breaking the bank).
