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
