To caulk or not -- base of porch column

Might be a good idea to seal the base of the columns with
penetrating epoxy or something, too.
That's probably a great idea.
When I have to put posts on ANY surface, I seal the bottom with NP1
(an elastomeric UV resistant sealer/adhesive) swabbed on with my
finger. If I can, I also lift mine up and put a fat bead of the same
stuff all the way around the bottom.
SFWIW, While SikaFlex not only makes a very good line of marine
sealants, their primary business is in the construction market.
Their tech service is very good and has an 800#.
Think I would treat the bottom 6"-12" of post with that green goop
(Can't remember the name but probably a Flood product) intended to
protect wood in wet locations, prior to painting.
Did this on an outdoor work benck setting on a concrete slab with good
results.
