Wood fence post coated with tar?

[MiamiCuse]

I had a wood fence built last year, the code calls for 4x4 PT posts embedded
in concrete 12" deep, which is what I did. I have always wondered how long
this PT post would last in the hot and humid Miami sun and rain.

A few days ago I drove by a house where they just had a new wood fence up.
I noticed the bottom of the fence post where it meets the ground all of the
post had been painted with something black with the consistency and texture
of tar. I am pretty sure this is something done to prevent the post from
getting in contact of water. Wish I had thought of that, and curious if
this is a common procedure. I hope my posts will give me at least 5 years
before I have to do it all over again.

Before I planted my fence posts, I coated the bottom of the posts with that
tar-like black stuff that you can coat driveways with. Driveway sealer of
some sort, black, tar-based. I don't really know what if any difference it
will make. I bought mine in a 5 gallon bucket at Home Depot for somewhere
around $20 or so.

Better to use a special tar mix that is used to coat the concrete walls
below grade before backfilling. Most times it is brushed on then heavy
plastic sheeting is stuck to the tar to provide additional
waterproofing. It is available at the big box stores, and may be
available in smaller stores.

Somehow I doubt it would do much good and was probably done to impress the
fence installer's client. Tar coating the wood would do little to prevent
water from eventually soaking the bottom of the post and little to prevent
decay. Once water got into the wood the tar probably would slow down the
wicking away of the water during dry periods enhancing rot. If it isn't a
substance that soaks deep into the wood and also kills the rot fungus it
will do little else.
