Frequently Asked Questions

 

What is seal coat?

It is a general term for any of a variety of coal tar or asphalt emulsions applied to a relatively sound asphalt surface to prevent damage from ultraviolet rays, moisture and oxidation.

 

Why should I seal coat a driveway or parking lot?

Seal coating protects the asphalt and extends the lifetime of the asphalt surface by preventing water and the sun’s UV rays from breaking the asphalts binder (what holds the small stones together in asphalt).

 

How do I know when I need to seal coat?

The best way to tell if you need to have a new top coat of sealer is by visual inspection. If the surface is light gray in color, or is starting to show crack, then sun and water is penetrating into the asphalt surface eating away at the asphalt binder.

 

How long does seal coating last?

We only use the top quality coal tar sealer. Unlike our competitors who use a synthetic blend, or watered down blend, our coal tar sealer will last 2 to 4 times longer. On average it is recommended to re-seal a driveway every 2-4 years depending on traffic amounts, sun exposure, or oil and gas drippings.

 

What make your sealer better than others?

Coal tar sealant is a thicker and more wear resistant product that bonds with the asphalt to protect it. Synthetic or watered down products have a thinner protection barrier between the asphalt and top surface, shortening the time till water and wear get to the original asphalt surface. The bonding strength of coal tar sealer, and the thicker protective layer will provide you with years of a maintenance free surface.

Our sealant meat and exceeds the following industry standards.
ASTM D5727
RP 355e
ASTM D-3320-74t - ASTM D-3320
FAA P-627 & P-628
US Air Force specifications

 

What about hills and high traction areas?

We are one of the only services in the area that has the ability to custom blend sand into our sealant for a custom application. We store our sealant at our yard (not in our trucks) allowing us to make a custom sand and sealant blend for surfaces that need that extra grip. If you have a driveway on a hill or a turn that needs extra traction, we will add more sand to give you better traction.

 

Somebody stopped by my door and said they could seal coat my driveway cheaper. Can you match their price?

9 times out of 10 we cannot because the material cost prevents us from doing so. With Seal-A-Drive you are paying for the best protection possible. Our craftsmanship and material costs do not allow us to match many door-to-door sales. We cannot vouch that the product that was offered is not a very watered down synthetic that will only last a year.

We find these types of sales are for a quick application, and do not address the needs of the homeowner. Many of these providers have a small tank of sealant that was watered down to extend the amount of applications they can provide. In some cases, you will notice the surface turning gray by fall, which indicates the sealant is not doing it’s job.

 

How long do I have to wait after seal coating until I can park/ drive on the surface? What about walking across it?

Depending on the temperature and humidity of the air, you should keep vehicles off the new surface for 48 to 72 hours. You may walk on your driveway within 24 hours. After walking across fresh seal coat, please check the bottom of your shoes, or remove shoes before entering into your home.

 

Why are there tire marks showing on a newly seal coated drive?

The material dries to the touch in a few hours but takes several weeks to fully harden, especially in the hot sun. Expect power steering marks as the sand may shear away from the sealer. However, over time these marks will dissipate. The drive may be lightly misted with your garden hose if necessary.

 

Why can’t the alligatored areas be crack sealed?

When alligatored areas appear in the asphalt it means the has water penetrated the sub-grade layer and the pavement can no longer support the weight of vehicles. Crack sealing is no longer an option; saw cutting and hot patching is the proper solution. The damaged asphalt must be replaced at this point in time.

 

What are the wait times for asphalt patches?

For best Results, we recommend 24 hours for pedestrian traffic,

(3) days to drive over the asphalt and (1) week for parking on the asphalt.

 

 

Are the wait times the same for repaving/paving or extensions?

Yes. The above guidelines should be followed for these services.

 

You provided asphalt services but the drive was not sealed. When will it be sealed? 

Fresh asphalt needs time to cure. We will schedule your seal coat according the following guidelines.


Extensions, Patches - seal within 2-4 weeks
Repaving, Resurfacing - seal within 2-5 months

 

I’m only available at a certain time; can you seal coat my driveway at that time?

We try our best to meet your needs. Unfortunately, as we take care of many driveways at a time we can not guarantee we can meet your times. A normal driveway can take from 15 to 30 minutes to complete. We understand homeowners wanting to be around while we seal coat, but if you are not around feel safe that we can anticipate your concerns.

The most common concerns we find are:

Do you edge the driveway before applying the sealant?

Yes

Do you clean the driveway before application?

Yes, we use steel brushes, and air blowers to remove grass, dirt, rocks, and anything else that might be between the sealant and asphalt.

Do you & I want to make sure you fill in the cracks.

In our process, after clean of the asphalt surface, we inspect for any cracks that water can get into. We apply a thick tar based filler/ sealant to protect the cracks we find.

I want to make sure the black top does not get on to my sidewalk, paver stove, garage concrete, curb, lawn, etc.

We have the same concerns and do not want to get sealant on anything other than the asphalt. We take our time to make sure the sealant is applied only where appropriate. Our professional sealant teams meticulously slow down and controls the application where asphalt meets any other surface.

I don’t want foot prints.

Another common concern for homeowners. When our team arrives, we place down a mat or sheet of cardboard to use as our steeping off point. Any crew member who works with the sealant and walks through the sealant exits the drive via the mat to remove excess sealant from their boots. We carefully avoid any other surfaces that sealant may be transferred to.

I have another concern not listed.

Please call and let us know any concerns you may have.
