In any case, what you describe is common. Several
factors can contribute: Column bases are often exposed
to the weather. Modern water-base paints don't stand
up to moisture. Water can wick underneath.
Solutions are limited. I would scrape it and leave it to
dry out. Then put a good oil-base, linseed oil primer on it.
Maybe also use caulking around the base, if that's feasible.
Then preferably paint it with oil paint. Sherwin Williams
still sells exterior oil paint in quarts. Next best would
be oil-base solid stain. Failing that, use a decent acrylic
or latex paint. It won't hold up, but the primer will hold
it for awhile.
I'm painting my front steps and the stoop. The paint has been flaking off
the bottom of the support columns, when I peeled it off the wood underneath
is waterlogged. This isn't the result of one particular storm, I remember
last time I painted, year or two ago, they were wet then too. The columns
appear to be at least partially hollow, so my first though was to drill a
hole from underneath and create a drain, but there must be some metal
hardware involved because I couldn't drill through. Should I be looking for
a leak from above (the tiles on top of the stoop look fine)? My other
though was to drill hole toward the bottom pillars and stick in some kind of
plastic vent to allow the moisture to escape. Any ideas? Is this a common
