Pressure washing, scraping, stripping, sanding–it’s dirty, hard work. In fact, greater than fifty percent of the time spent working on a home’s exterior finish should be devoted to surface preparation. This kind of preparation is particularly important here in New England where we experience such a wide range of weather. Historic homes (100-400 years old) are especially vulnerable because their thicker layers of paint become impermeable and too brittle to flex with seasonal changes of humidity and temperature. http://m.www.youtube.com/embed/b6_WEt9k_Hw
If you paint over dirty, oily surfaces, the paint will easily chip or peel off. So before painting, clean grimy areas with a deglosser or heavy-duty cleaner intended for prepaint cleaning. They work well to clean painted, varnished or enameled surfaces to improve the adhesion of the new paint. They’re ideal for cleaning greasy or oily areas like kitchen and bathroom walls and removing hand marks around light switches and doorknobs.
