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 wooden surface already has some chips, pressure washing will only aggravate the problem. When pressure washing, many painters approach the surface to try to remove loose paint. They're often successful, and then that 3,000 psi water pressure seeps directly onto the bare wood.
It digs holes in the surface and removes the grain from the wood, damaging the coating. Wooden decks are especially vulnerable to pressure washing because the pressure exerted by the pressure washer can cause chips. If there is an area of the roof where the wood is already starting to split, pressure washing it will aggravate the problem and cause the split area to expand. If you have a house with any type of exterior or wood cladding (clapboard, lapel, boards and slats, shingles, 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 technique, soft to the touch, that does not damage the surface. A pressure washer can clean a wooden deck much faster than it can be scrubbed by hand. However, a pressure washer will often destroy the surface of the wood.
The water stream can be powerful enough to erode light-colored spring wood fibers. Those that are not eroded can peel off, leaving the wood fuzzy or rough after drying. Since you're most likely pressure washing outside, you should pay attention to the weather forecast. Pressure-washing air conditioning units can destroy delicate metal fins, which can compromise airflow.
Although it seems obvious, you should never pressure wash living beings, such as humans, pets, or plants. Although designed to withstand a storm, pressure washing can cause water to enter cracks and crevices and cause damage and costly repairs. Washing the house with a high-pressure washer is very likely to spill water underneath the siding, which could soak wall cavities, insulation, wiring, floor, plaster, etc. When pressure washing in preparation for a painting job, many people come to the surface to try to blow loose paint off.
Sometimes, when an owner doesn't add a cleaning product to the washing solution, they can try to compensate for poor cleaning results by increasing equipment pressure. If this is your first time pressure washing on a large project and you have no experience, you may not know that there is a proper order for cleaning the outside of your home. If you think you really should pressure wash your house, it's very important that you do it correctly. Worn bricks from homes and other landscape surfaces that use mortar can be damaged by pressure washing.
Unless you like to engrave your name on the side of your house with water, this is yet another reason not to pressure wash. While they can withstand heavy rains, pressure washing can cause water to enter crevices and crevices and cause damage, resulting in the need for costly repairs. Often, in the painting process, a house is first pressure washed, then caulked and patched, and finally painted. In most pressure washers, power output is measured in pounds per square inch (PSI), and many pressure washers are capable of reaching 3000 PSI.
