I had an exterior wall that would literally start pealing in a couple of years. I did something similar in that I stripped the wood down to bare wood. Set all nails down into the surface, used an epoxy filler to fill the holes and then I used a very thin coating of a two part liquid epoxy and a special thinner for epoxy. This was a very thin clear paint like material, some would call it a spit coat. After that dried I would lightly sand any fibers that were brought up by the spit coat. Then a coat of oil based primer, another light sanding than two coats of latex paint on top of that. It's been almost 20 years and the paint is still good. The paint had a very slight cracling look if you got up close and look but it is as tight on the wood as the day I put it on. The epoxy thinner and liquid epoxy, I got from a company called Abetron out of Kenosha wisconsin . They sell all sorts of epoxy materials. They ship anywhere in the world. It was a lot of messing around for the paint job but we'll worth the results. I have used this same technique on other walls of my home. Rather than try to complete the whole house I would concentrate this effort on one section that for one reason or another would not hold paint. Usually it was moisture coming out of the building I believe that was causing the paint to fail. There's nothing that sticks better than epoxy.
Cool
I don't know anyone that paints their home every 3-5 years.
