What procedure do I take to paint latex over oil base (outdoor veranda)?

You should be able to use a top quality exterior latex paint over oil based paint, if the surface is well prepared. (However, if the old paint consists of a buildup of say 5 or more coats of old oil paint, the safest approach is to continue with oil, because the latex paint can lift the old oil paint if not adhering well.)





All dirt, mildew and loose paint should be removed. Sand any glossy areas to eliminate the gloss and get maximum adhesion from the new paint. NOTE: do not sand or otherwise remove any old paint if it may contain lead. Call the EPA at 1-800-424-LEAD for guidance. Some quality exterior latex paint may be applied directly to clean, sound oil-based paint; but check the product directions, as some manufacturers will require a primer, either latex or oil-based.What procedure do I take to paint latex over oil base (outdoor veranda)?
Exterior Oil base paint is nasty stuff...peels as wood swells and shrinks with varying humidity. Scrape ANY blistered or peeling paint , sand the rough spots. Apply a primer and paint with exterior grade latex, Semigloss will be easiery to wash and keep clean. Any new wood, prime and paint with Exterior grade Latex ONLY.
