Like interior paint, exterior paint is available in both latex and oil-based formulations—both of which are designed to withstand wear and exposure to severe weather conditions.
The advantage of exterior latex paint is that it films on exterior wood allowing moisture to evaporate through the film, which helps reduce blistering.
The disadvantages of exterior latex paint, especially of some lower-quality products, are poorer adhesion to badly weathered or chalking surfaces and, in some cases, less effective hiding qualities.
The best qualities of oil-based paints are their effective penetration of the surface and excellent adhesion. Oil-based paints have advantages over latex paints in that they adhere better to chalky surfaces and they provide better results for anyone repainting a surface that already has several layers of oil-based paint.
Trim paints are chosen to contrast with house color. They dry quickly to a hard finish; they are primarily for use on window frames, shutters and railings. Trim paints are not recommended for large surfaces.
Flat finishes, which mark easily, should not be used on doors, door frames or other areas that are exposed to wear. Satin or gloss paints are recommended for these areas.
Major problems associated with house paints are generally due to:
failure to follow manufacturer’s directions
excessive moisture
painting wet surfaces
painting during inclement weather
failure to use proper primer coat
failure to clean the surface completely.
Any of these conditions can cause blistering, peeling, early fading or similar problems.
