I've been talking to handymen, general contractors, and a painter contractor about repainting my home's exterior. Most of them suggest or bid various solutions that don't involve priming the entire exterior. My current exterior is the original paint supplied with my model year 2002 manufactured home. It's a Glidden I.C.I. product, but maybe that's not important. In some places, the paint is almost as good as new; it others, there are spots where it's gone and bare pressed wood shows. The thing that worries me is that my current paint is all satin finish (both the siding and the trim). The surface seems slick enough that I'm not sure whether the new coat of satin paint will adhere as well as it should. On the other hand, if you painted some wood with the usual two top coats of paint, you wouldn't worry about the second coat peeling away from the first coat. So maybe the sheen is nothing to worry about. Plus, I've read a suggestion that all latex paints are naturally self-priming, in the sense that they will bond to any existing latex paint. Is priming only for bare wood? Or should I require that the whole house receive a coat of primer? Or something else? Thank you very much for sharing your experiences with this issue.

I need to repaint an exterior wood door. Including the entire door slab inside, outside, the door edges, and the wood jamb. I painted the entire door with the door hanging open. Let it stay open to dry. Seems dry to touch in 30 minutes but let it stay open for 90 minutes before I closed the door, locked and left. Six hours later I came back and opened the door the hinged side edge, which kind of touching the jamb, pulled some paint off the jamb as I opened the door. Is there a trick to prevent the paint from sticking other than waiting a long time for it to dry/cure? How long a wait do I need? Obviously 90 minutes was not enough. I was using basic acrylic exterior paint. Home Depot Behr brand.
