How to Pressure Wash Your Home Exterior Prior to Painting

Pressure Wash Your Home's ExteriorProperly preparing the outside of your house for paint is extremely important. All exposed painted surfaces develop a layer of electrolysis dirt film, and most cleaners cannot penetrate this film. This is where degreasers come in handy for removing film when used with a pressure washer. Shipp Cleaning Systems carries a product called CREST, which has surfactants that penetrate static films and all dirt without harming the surface. If the electrolysis film is not removed before painting your house, the paint will not bond to the surface, causing premature chipping. CREST cleans away all grime, dirt, and films.

Pressure Washing: as easy as 1, 2, 3

1. Most portable pressure washers have a chemical injector hose that goes directly into the CREST container. With the chemical tip on the wand, this will spray out at either a 1-10 ratio or 1-15 ratio depending on the machine. This dilution is good for medium-to-heavy dirt on a home. If the dirt is light, the CREST may be pre diluted by half in a bucket.

2. With the chemical tip on the wand and the injector hose in the CREST solution, you are ready to apply the cleaner on the surface from the bottom up. Apply from the bottom up to avoid clean streaks. Also apply to the dry surface, do not pre-wet with just water, letting the chemical be the first thing that touches the dry surface will do a much better job of cleaning. To avoid wasting cleaner, move quickly and evenly, applying a film of CREST over a section of about 30 running feet at a time. DO NOT LET THE SOLUTION DRY ON THE SURFACE! Change tips to a 15-degree, 20-degree, or 25-degree tip. Now pressure wash from the bottom up. This is the cleaning step. By cleaning from the bottom up the pressure washer water is the first thing to hit the chemical as it sits on the surface. If you clean from the top then down the water that cascades down will wash off the chemical cleaner before it is hit with pressure. Hold the tip of the wand approximately 18″ from the surface. This is the action that cuts and cleans. Take your time and spray evenly.

3. Finally, rinse the area from the top down. Make sure CREST is completely and thoroughly rinsed off ALL surfaces including windows and shrubbery. It will take approximately 1 gallon of CREST, at full strength, to clean a single story, 1500 sq. ft., house.

Helpful Hints:

  • Spraying: The chemical spray tip will spray cleaner out as a mist, not at pressure. After applying cleaner, the 50-foot hose will contain cleaner. By putting the 15-degree tip on the wand, you will get chemical at full pressure for about 8 to 10 seconds. Use this time to apply cleaner to eaves and hard-to-reach areas.
  • Protect your plants: Always spray down shrubs and plants with water before cleaning. This layer of water helps prevent “brown tipping” of leaves of plants by incidental cleaner contact. CREST is biodegradable.
  • Sprayer Tips: The tip of the wand should be held at 18” from the surface. The 15-degree tip has a smaller fan pattern that cuts hard-to-clean surfaces.
  • Spray Patterns: Always apply from bottom up to get a good, even cleaning. It will eliminate streaking and blotching the surface. Clean from the bottom up. Otherwise, cleaning from top down will dilute cutting ability as runoff water rinses cleaner away. Rinse from top down to insure all cleaner is removed.
