Exterior Pressure Washing Before Painting

We highly recommend pressure washing the exterior of your home before you paint. Pressure washing on the average home uses approximately 150 to 200 gallons of water, not much when you consider the average homes uses about 75 gallons per day.
Washing the home removes dirt, loose paint and mold and mildew stains. It also gives the paint a good surface to bond to .The most effective way to remove mold/mildew is to use a cleaner as the second step in the washing process. The cleaner can be applied via garden sprayer or a chemical cleaner injection feature that comes on most washers. Follow the instructions on the cleaner you choose. Most importantly do not use bleach. Bleach does not kill mold, it only makes it appear as if it has been killed. Actually bleach spreads mold. Bleach also is caustic to the environment and can void your termite contract. Remember to keep six to eights inches distance from the wand and the surface being cleaned. Also, start by using the widest tip possible to avoid damage as well. Start by cleaning/sopaing from the bottom up and rinsing from the top down. This way you always have clean water running off cleaned areas.Lastly remember, let the machine and chemicals do the work!
