There is more to sealing than cosmetics.


So how come those of use in the freeze thaw states don't see every
parking lot out there being sealed.

Many do. It's a choice the owner of the lot can make.

The only time I see it is when
they are looking to dress up the appearance or move the parking
space alignment. Otherwise it doesn't happen. Must be a big secret
that it's so effective - they don't even share it with businesses
who could buy the service.

Maybe it's a cost they are not willing to pay at the time.. A phrase
comes to mind. "You can pay me now, or pay me later"

There are parking lots that have crack sealer applied to the major
cracks, just like the roads. No surface sealers.

If they were smart they would use crack sealer along with seal-cote.
