3 Reasons To Pressure Clean Before Exterior Painting
Every professional painter knows that the surface prep work is the most important first step, and it couldn't be truer for exterior painting. Pressure washing the exterior before painting will make a big difference in the quality of the results.
Here in Georgia, houses are usually covered in some type of algae or mildew. While you may hear some say that pressure washing is unnecessary before painting, this is the worst type of misinformation you can get. When a pressure washing company does the job right by using gentle methods like soft washing, the exterior painting results will be superior.
Paint Adheres Better
The grime, mold, mildew, or algae layer that covers the siding and trim must be removed before painting or the paint won't adhere to the surface as well.
Soft washing is a pressure cleaning technique that uses a gentle cleansing formula which contains a biocide to kill algae, mold, mildew and other microorganisms. The process treats the algae and then rinses it from the exterior surfaces of the house. This soft wash pressure washing technique is the only proper way to prepare an exterior surface before painting and is the only approved method that siding manufacturers recommend for cleaning.
The soft washing formula will also help to prevent new algae growth. Don't listen to people who tell you to use bleach. While it may kill algae, the problem will only come back in a short time. You don't have to use harsh chemicals like bleach.
Smoother Paint Results
House washing removes any material that could cause defects in the paint finish. Whether your exterior painter plans to spray, roll, or brush the paint on, the surface should be smooth and clean if you want to achieve the best results.
Exterior Paint Jobs Last Longer
When the exterior paint is applied over grime and algae or mildew, it won't be able to bond properly with the surfaces. This can cause tiny bubbles, ripples, and paint lifting in just a short amount of time. Once water seeps in behind the paint, your whole house will be covered in a bad paint job that has to be scraped off and redone. With a clean, smooth surface, the paint will adhere as it should.
