Frequently Asked Questions
When painting the exterior of your home:
- always start with a clean surface;
- paint one side of the house at a time, starting with the highest point;
- apply a full even coat to one side of the house at a time;
- and always paint the trim last.
This depends on the condition of the surface you are painting.
Surfaces must be clean before painting. Thoroughly wash with a house cleaner and water solution, making sure to remove any and all mildew. Rinse and allow the surface to thoroughly dry.
If there is loose or peeling paint, scraping and sanding* of the affected area is needed. Remove all sanding dust by rinsing, and allow the surface to dry.
The appropriate exterior primer should be applied to any bare or stained surfaces.
Visit our Painting Advice for more tips on preparing to paint.
Generally you should only paint when the surface is between 50F and 85F. High temperatures cause the water in the paint to evaporate too quickly, resulting in bubbles/blisters, while low temperatures prevent paint from drying properly.
Always avoid painting in direct sunlight, strong winds, or when rain is expected within 48 hours.
To achieve one-coat coverage, paint should be applied at a maximum of 400 square feet per gallon. Rough or textured surfaces may require more paint. On these areas allow for 25-30 square feet per gallon. Some bright colors may require multiple costs to achieve sufficient hide.

Removal of old finishes by sanding, scraping, or other means may generate dust or fumes that contain lead. Exposure to lead dust or fumes may cause brain damage or other adverse health effects, especially in children or pregnant women. Controlling exposure to lead or other hazardous substances requires the use of proper protective equipment, such as a properly fitted respirator (NIOSH approved) and proper containment and cleanup. For more information, call the National Lead Information Center at 1-800-424-LEAD (in US) or contact your local health authority.
