I'm sure this has been debated before.

Yes, and the intelligent conclusion is that even if the coatings worked,
they are horrifically expensive per pound of material applied, compared to
new bulk asphalt. You're much better off saving your money and applying it
to new asphalt when that day comes. So-called "sealers" are an expensive
way to paint a few thousandths of an inch of asphalt on top of inches of
asphalt.

Now if you really, really like the look of a fresh paint job, then maybe it
is worth the money and/or back-breaking effort on that basis, but the
alleged durability claims would be a false economy, even if they weren't
dubious.

Take a look at what bulk asphalt typically costs your paving contractor:

Now compare that to what retailed sealers cost, which are mostly water and
clay and sand, and relatively little actual asphaltum.


OK, you have a materials comparison. Now, try hard - can you think of any
other factors? Like pavers and other heavy equipment being brought to the
scene? Compared to what a lot of homeowners are willing to do at the cost of an
old pair of sneakers and enduring some heavy, smelly work?

You seem to be on a campaign about this thing...
