Oil based driveway sealant
- Thread starter applet
- Start date
Most driveway sealants are oil based they have to be to bond with the asphalt which is an oil derivative. The hot sealant actually melts into the top layer. This makes a stronger bond with the existing asphalt.
The condition of your driveway is very important small cracks can be filled but large cracks or missing pieces can compromise the sealing job.
Check out the company as well that is one of the less respectable sections of the construction industry.

There is often a strong smell of diesel which i suppose is used as the thinning agent to dilute the main blackening constituent so that is passes through the spray gun fluently.
Most do a neat job, it gets done quickly and it dries pretty well and does last till next year so for $45 I suppose it can't be too bad.

Clean the drive way with a backpack blower & broom, top 2 bottom, one guys sprays BITUMEN on the driveway, mixed with a litre of diesel/200 litres in his tank (a cold day only) & the other one holding the board along the edges, 2 sticks is the grass, and tape her up. $75 is nice price for a 4 car garage, by the way they will dry up all the oil stains for an extra $25 wich would mean an even $100, The neighbours are all coming out and suddenly you have 25 driveways on one street done within a couple of hours as the other truck has shown up with a simple call from the boss and it's a good show and a good night if you know what I mean!
The acrylic stuff or coal tar emulsion will stay on top of the asphalt and not seep through, therefore there will be alot of hair line cracks building up over the years, best is to use the oil based, actually best to not even seal itapplet said:
Hey applet, if you really want to know what your getting and not be screwed make sure that the company that is doing the job has a TDG certificate to transport the oil, if he doesn't, he is not allowed to carry the stuff, and it is probably water based, so stay away
I thought you gave up the sealer business to be Sara's "phone guy"?Aloha511 said:The acrylic stuff or coal tar emulsion will stay on top of the asphalt and not seep through, therefore there will be alot of hair line cracks building up over the years, best is to use the oil based, actually best to not even seal it

the driveway cracks are from the freeze thaw cycle we get here . The breathing driveway is irrelevant.
You need to add a sealant every few years to restore the oil based layer to the top. Wear from the sun, rain, snow, salt and your vehicle will force the tar lower and expose more of the agregate. As stated, moisture will seep into the cracks and freezing will cause the cracks to expand and eventually pop chunks.
Asphalt is made from rock, sand and tar (oil), the sun dries up the oil, and it's now time to spray it back onto the asphalt penetrating in at the same time

So even more oil can evaporate into the atmosphere. How is this a good thing?Aloha511 said:
Note that current environmentally-responsible thinking advocates water-permeable paving for parking and low-use traffic areas—like driveways. Wouldn't it be better to save the ever-scarcer petro-products for more vital purposes and let the driveway crack?
Problem is that once a driveway cracks it will also start loosing chuncks. Then you may need to patch it, requiring more oil based products. Then you may actually need to replace the driveway, requiring a significant amount of oil based product.
The simplest way is to pour concrete on a new driveway, eliminating the need for oil based products all together. Much more expensive but I think it looks better as well.

Asphalt is the last thing that comes out of the cracking tower in the refining process. It is basically not good for anything else than the current uses. Oil does not evaporate the surface tension is too high.oldjones said:
I saw a road with cracks and some minor holes repaired with tar sprayed on it. Afterwards a layer of stone was applied and a roller compressed the mixture. 15 years of heavy traffic and weather and it still looks good.
