A pressure washer is used to remove old paint from a boat.
Pressure washing or power washing is the use of high-pressure water spray to remove loose paint, mold, grime, dust, mud, chewing gum and dirt from surfaces and objects such as buildings, vehicles and concrete surfaces. The volume of a mechanical pressure washer is expressed in gallons or liters per minute, often designed into the pump and not variable. The pressure, expressed in pounds per square inch, Pascal’s, or bar, is designed into the pump but can be varied by adjusting the unloader valve. Machines that produce pressures from 750 to 30,000 psi (5 to 200 MPa) or more are available.
Hydro-jet cleaning is a more powerful form of power washing, employed to remove buildup and debris in tanks and lines.
tennis courts power washing
A pressure washer surface cleaner is probably the best tool for this job. First prepare to power wash the tennis court by removing any debris (leaves, balls, and any object that is big enough to pick up by hand). Secure or remove any object that could be pushed by the pressure of the jet such as trashcans, counters, or plastic chairs. Anything that is lightweight and can become a projectile should be taken out. A pressure of 2000-2600 psi should be plenty to clean dirt and any mold that took hold on the surface. This will not only result in a safer court but will also save long term resurfacing costs by extending the life of the surface.
