Hi,

I had some work done on a wooden porch and some dry rot
was replaced with durham's wood putty. It dried for one day then
was painted with valspar ultra latex. It gets wet and peels.

I repainted it and covered it with plastic to allow for drying but
it still peels.

Can I just scrape this and seal it with polyurethane then use
something like Kilz on it? It is a satin white and a small area
so perfect color matching is not that important. Or does the
peeling indicate something else.

thx,

itchy

Durhams is fairly junky, at best it will last 4-7 years, painting
after one day was a mistake, it needs to dry completely, covering a
repaint with plastic makes no sense since you trapped everything from
curing out. Wood was rotted, so it had water leaking in at some point,
or it would not have rotted in the first place. Sounds like a big new
experiment for you, ive had good luck with Bondo. Paint is probably
failing now because of incomming water so fix that first, the durhams
wont ever dry if water is leaking in and any oil paint will peel more
readily than latex from moisture, latex breathes a bit.
