I have to disagree. If a crack even a small one gets water in a freeze thaw location it will only get worse. This is why every year around this time you see many towns and Cities go around and fill these, at least here in upstate NY.
Gotta disagree. I sealed the driveway twice in the 20 years I lived there and the sealer never came off. The driveway was still in perfect condition when I sold the house. My neighbor never sealed his driveway and he had to have his redone.
BTW, my current driveway sealer isn't "coming off" or maybe I should say there's no signs of the sealer lifting from the asphalt. I think there's just some sort of film on top that only becomes a problem after a light rain. We have recently had a really heavy rain in my area, so I'm curious to see if the issue happens again or not.
Of course you haven't....why would a paving contractor recommend sealing a paved driveway? They'd much rather replace the driveway sooner.
It seems silly to debate whether or not driveway sealer is beneficial to driveways. Maybe next we can talk about how waxing your car isn't beneficial either.
Actually it is done all the time with older, failing pavements as a surface treatment. Usually called “chip sealing” since they cover the liquid with small stone “chips”.
Read the whole post!
Sealing has it's place on a cracked or deteriorating driveway, and serves no purpose on new. Again, have you ever seen a municipality or state road "sealed" ? No.
There is a technique called "slurry seal" that they do use, again as a "band aid" that is very similar to the old "tar & chip".
And that is completely different than what is called "driveway sealer". In PA they spray oil on roads and then spread QP on it. That isn't a sealer either.
Good paving contractors don't offer it because the stuff they use (Oil Based Sealer) doesn't really work well.
You probably had one of the "old" sealers. They worked much better than what is used today.
I have over 85 acres of blacktop in my district. The BOE was considering sealing last year and I had to do a LOT of research before they made a decision. They voted "No".
Asphalt driveways are primarily stone & grit. The asphalt is just a binder.
The driveway sealer sales reps say that UV from the sun causes the asphalt to deteriorate, causing cracks. That's sort of true. UV exposure oxidizes asphalt, causing it to become brittle and lose it's ability to bond the stone. Fortunately, this only happens at the very top surface of the blacktop and it takes
many years to have any real damage. On a new driveway, the thin coating of asphalt on top of the stone and grit quickly wears off, leaving a very small amount of asphalt exposed to the sun. 90% of the surface exposed to UV is actually stone. The real cause of cracks is the gravel underlayment was done improperly.
Blacktop (and concrete) respirates. Sealing it holds moisture in, which in time damages the base material.
Do some products work better than others? Absolutely. The old Coal Tar Emulsion stuff works really well and is still used on airports and highways. It's kind of gray, so homeowners generally don't like the "look". Unfortunately, it's not really in wide use anymore. It has an average life span of 5 years.
Asphalt Emulsion makes a driveway really black. It's more of a recoloring than anything else. UV degrades it REALLY fast. Like I said, you might even have to recoat annually. Better sealcoating companies mix Coal Tar and Asphalt Emulsions to give a good "look" and durability.
Oil based sealer is the lowest grade stuff. It's what paving contractors use because they have it at their asphalt plant and it smells for days. It also takes a week or more to cure.
Asphalt and oil based sealers have an average lifespan of 1-3 years.
The Latex-ite you used is an asphalt emulsion with no coal tar emulsion mixed in. It's also primarily water. The water is supposed to evaporate and leave the coating behind. Maybe you just had a really heavy coat and it still has a little moisture left in suspension that hasn't evaporated off yet. Hopefully, it will "skin over" and your issue with wet tracking will stop.
On a separate note, I wouldn't let one of the "spray on" sealer companies that go door-to-door touch any black top I cared about. You might as well paint your driveway before you use one of them.
