Preparing the Surface

Surface preparation is critical to a successful exterior stain project:
Repair or replace old or damaged areas.
Caulk around doors and windows.
Patch holes in wood with wood filler.
Use drop cloths to protect plants, sidewalks and decks.
Remove dirt by washing with soap and water.
Remove mildew with a commercial mildewcide or use a solution of three quarts water to one quart chlorine bleach. Wet the siding with the bleach solution and allow it to remain on the siding for about half an hour. (If you are not sure whether the stain is dirt or mildew, put a drop of household bleach on the spot. If it lightens in 1-2 minutes, it is mildew.)
Scrub the surface with a soft brush.
Rinse thoroughly.
Wear protective clothing and eye protection when using cleaning chemicals.
