Beware of damage caused by pressure washing: If you have wooden boards, the pressure of a pressure washer can cause chips and damage wood fibers. If the surface of the wood already has some chips, pressure washing will only exacerbate the problem. When pressure washing, many painters approach the surface to try to remove loose paint. They are often successful, and then 3,000 psi water goes directly into the bare wood.
Dig holes in the surface and polish the grain of the wood, damaging the coating. Wooden covers are especially vulnerable to pressure washing because the pressure exerted by the pressure washer can cause splinters. If there is any area on the platform where the wood is already starting to split, pressure washing will exacerbate the problem and cause the divided area to expand. If you have a house with any type of exterior or wood cladding (slats, flaps, boards and slats, tiles, etc.) , nothing is beyond the reach of a powerful water gun.
It is also advisable to avoid wooden surfaces, such as outdoor furniture. The pressure and heat of the pressure washer can remove stains from these surfaces, so they must be done carefully and with a special soft-touch technique that is softer to the touch. A pressure washer can clean a wooden platform much faster than it can clean it by hand. However, a pressure washer will often destroy the surface of the wood.
The current of water can be powerful enough to erode light-colored spring wood fibers. Those that are not eroded may peel off, leaving the wood blurred or rough after drying. Don't create a dangerous situation or break glass; avoid pressure washing windows or other glass surfaces. If you feel like you should really pressure wash your house, it's very important that you do it correctly.
Although outdoor lighting can withstand rain and other weather elements, you should not pressure wash these accessories. Lead paint is highly toxic and dangerous; it should be avoided whenever possible and these surfaces should not be pressure washed. Although they can withstand heavy rain, pressure washing could cause water to enter cracks and crevices and cause damage, resulting in the need for expensive repairs. It is very likely that when you wash your house with a high pressure washer, water will accumulate under the coating, which could soak up wall cavities, insulation, wiring, floor, plaster, etc.
Although you can adjust the pressure of your pressure washer, it's still high enough to damage most items and materials. When the most persistent stains require cleaning power at maximum pressure, you should do everything possible to keep the washer nozzle at pressure perpendicular to the dirty surface. When pressure washing in preparation for a painting job, many people come directly to the surface to try to remove loose paint. If this is your first time pressure washing on a large project and you don't have experience, you may not know that there is a proper order to clean the outside of your house.
Although it seems obvious, you should never pressure wash living things, such as humans, pets, or plants. When pressure washing suitable surfaces, always wear safety glasses to protect your eyes from dirt. Any loose material, especially in old structures, will be removed by washing it under pressure at high temperature. You should not pressure wash the asphalt shingles from the roof, as this will remove the granules that protect the roof.
Pressure washing is usually the first step when you're doing a new paint job on the outside of your house, so you see a lot of painters doing it and doing it wrong. .
