I live in a dry climate and am planning to sand and repaint trim on my home. What is the best process to take to prevent pemature blistering and peeling of new paint?

Hi Hugh,
First scrape any loose paint from the trim,then sand it(if possible w/some sort of power sander,it will save alot of time!)or sand it by hand until only 'sound' paint remains.Scrub the trim w/ a TSP solution then rinse trim till water runs clear.Let trim dry at least two days before priming & painting.

saw a cool gizmo on Bob Yapps show - looks almost like a car polisher, but has three blades spinning underneath - attaches to a shopvac - he buzzed it over the siding a few times, not a spec of paint left... probably hard to find in a rental place though. not a bad idea to get a moisture meter too - don't paint over 15% moisture... and DON"T ever use a pressure sprayer!

was watching Bob Yapps show - he had a cool gizmo, looked almost like a car polisher, but with three spinning blades. hooked up to a shopvac, so no dust. probably hard to find at a rental place unfortunately. just don't let anyone talk you into power washing (at least on wood)... causes more damage, takes forever to dry 'cause it goes way down in the surface... and if you can get your hands on a moisture meter, don't paint over 15% moisture...
