Step 1
Examine the wood closely to see whether you want to paint the fence and then decide whether you want to use paint or an outdoor stain. Some woods, such as redwood, cedar or bald cypress, can be left natural. Others, such as pine and fir, take well to paint.
Step 2
Clean the fence with a garden hose and a high-pressure nozzle. Soap and water should not be necessary. Any cleaning can be done with a wire brush. Let the fence dry.
Step 3
Choose a primer-sealer that will cover the knots and occasionally oily spots of a softwood, such as pine or fir.
Step 4
Stir the primer-sealer thoroughly and fill the paint sprayer with the paint. Apply the paint from a distance of about 6 to 12 inches and always have the sprayer in motion when you are painting with the machine. The primer coat does not have to be solid, but still coverage should be at least 75 percent. Be sure to brush all runs and drips of paint with a brush right after you have sprayed and the paint is still wet.
Step 5
Let the paint dry for 24 hours.
Step 6
Proceed with the top coat in the same manner that you applied the first coat except coverage will be more complete. You also have the option of using the large paint brush to give all areas a brushed look. This requires spreading the wet paint with the brush until every spot of wood is covered. An alternative method is to just use the brush on paint build-ups and thin spots.
