Pressure washing means using high-velocity water spray to clean dirt and residue from the exterior of the house. It is also known as power washing. This is basically done as a preparatory step before painting or re-painting a house. The reason it’s done is to acquire a neat and clean surface, which allows paint to last longer.
You can use the pressure washing equipment on most types of housing material; once you learn to pressure wash a house. However, the setting of the pressure washing would depend on the fact, whether you are applying detergent or performing high-pressure cleaning, and on the type of surface you are cleaning.
Here are few steps to follow for pressure washing a surface.
In a house, different surface can withstand different levels of pressure. So, make sure that you choose the one that is best for your house.
- Soft housing surface: Surfaces with painted soft-grain wood, aluminum or stucco, may require a wide spray nozzle to disperse water pressure.
- Strong non-painted surface: Surfaces with vinyl needs more powerful models. Strong pressure washing works best for them.
Make sure that you choose the one with detergent dispenser, if you plan to use a cleaning solution.
Protect your house’s exteriors, like lights, landscaping shrubs and plants, from harmful water pressure. In order to do this, cover them with drop cloth or plastic coverings and secure it with duct tape.
Try to manually scrub any visible from the surface that you are pressure washing with a brush.
Prepare the cleaning solution, and fill the pressure washer’s detergent dispenser with it. Use approximately 1 pound of non-phosphate concentrated cleanser with every 4 gallons of washing water.
For best results, connect a garden hose, hooked to the water supply, to the pressure washer. Let the water flow, once you are ready.
Before washing the surface, make sure to test the pressure. You can do it by holding the pressure washer nozzle with both hands about 3 feet from the wall. Keep moving it closer until you feel the spray is strong enough to remove the dirt but not strong enough to cause damage.
Spray the roof overhangs, under-hangs and gutter at approximately 45 degrees angle. Move the spray slowly and work your way down from the top.
Rinse from top to bottom, with plain water from a garden hose. Allow house sidings to dry for at least 2 days before applying paint.
After you clean your home exterior, you will also need to take care of the pressure washer. Your manual should include directions for relieving the water pressure, draining liquid from the pump and storing the machine. Follow these instructions to make sure pressure washing is ready for your next cleaning project.
