We recently restored a 1850s farm house in Georgia. Where we could save them we repainted the interior wall boards, but about half had to be replaced. Now just a few weeks after painting it is beginning to blister and peel.
Before we started the renovation we first pressure washed the wood (yes this was indoors but when we started working on the house it had no wiring, no sheetrock or insulation, not much flooring and little roof so the water did not hurt anything). Then a few months later we scraped cleaned and scraped the wood where it needed it and then calked cracks and holes then put on a good coat of primer followed by two good coats of paint.
The paint is only blistering on walls that had old paint on them; walls that got new boards are not blistering. Under the blisters you can see the old paint, not bare wood. Some of these are interior partition walls some are against the outside that seems to make no difference. We also repainted the exterior at the same time and so far no problems there.
The original wood is old Georgia pine. The replacement wood we put up is a combination of new t&g pine and some old recovered (1880s) pine that was recently planed so there was no old paint on it. None of the previously unpainted replacement wood that was painted the same way, at the same time is peeling.
My questions are does anyone have an idea as to what went wrong? How would you go about fixing it? And we paid a painting contractor a whole lot to do this, way more than a normal paint job to get lots of caulking and thick coats. We let the painter choose the paint. Would you go after the contractor on this?
Any learned advice will be appreciated.
