The important thing to remember about sealcoating is that it is a cosmetic process and not a structural repair. If your property requires any patching or crack sealing, these must be done first before the sealcoating takes place.
Sealcoating gives your property a uniformly black color that many people find very appealing. When you examine the surface, however, you will still be able to see areas that have been crackfilled or patched due to the different texture of the asphalt. Worn asphalt that has been previously sealcoated has a much smoother appearance than new asphalt that is just sealcoated the first time.
Yes. If you have a lawn sprinkler system, please make sure to cut it off. We will barricade areas that we have sealcoated, but you should advise your lawn service and trash pick-up to stay off of the surface for at least 2 or 3 days to prevent scuffing.
No. Sealcoating should only be done when the ground temperature is at least 50 + degrees. If the temperature is colder, the sealcoating may not to adhere to the asphalt surface very well.
We do not schedule sealcoating projects when rain is imminent, but if the product is down for 2 or 3 hours before a sudden summer rain shower, the surface has typically set adequately to prevent washing out of the sealcoating.
Yes. The traditional sealcoat that has been in use since before WWII is a coal tar-based sealer. This creates a hard, durable film, has a deep, dark color and has increased resistance to petroleum spills.
An asphalt-based sealer was developed in the 1980’s and is considered to be more environmentally friendly as it has lower PAH (polycyclic aromatic hydrocarbon) levels. These products do not smell as much and can dry faster. Their drawback is that there are strict mix specifications and they are not as forgiving in cooler temperatures.
John’s Asphalt most often uses traditional coal tar based sealer.
Coal tar sealer manufacturers, as well as John’s Asphalt, does not recommend that sealer be applied at night. We cannot warrant sealer that is applied at night. There are two factors that affect nighttime application.
First, the sun’s ultra violet rays are very important in the curing process of the sealer. When sealer dries from the rays of ultra-violent light, it forms a harder film, giving it a longer life. Sealer applied at night will not receive the crucial sun’s rays and the dry film will be softer, leaving it subject to premature wear once traffic hits the newly sealed pavement.
Second, at night, the humidity can be very high. You will notice that early in the morning, the grass is very wet and there is morning dew on automobiles. The morning dew also has an effect on sealer that is applied at night. The sealer cannot dry to a hard film, causing premature wear to the sealer once it is susceptible to traffic in the morning.
According to abrasion laboratory studies, sealer applied at night wore 3x faster than sealer applied during daylight hours.
