As we all know CUMOND pressure washers are powerful cleaning machines that can blast away layers of rust and paint from any surfaces. Before you begin, it is essential to prep the surface before adding a fresh coat of paint. You’ll need to remove peeling paint to provide a solid base for the new layer of paint. Not only will pressure washing remove loose paint and built-up grime, but this method will also improve paint adhesion, saving you time and money.

Time-consuming and outdated cleaning methods such as manually scrubbing and scraping only add unwanted labour costs and are ineffective in removing rust and peeling paint. Using a pressure washer will cut the time usually required in removing paint, rust, and corrosion from metal surfaces and with any other exterior surface as well.

However, careful consideration should be given to any surface and material before using a pressure washer. For example, surfaces such as old bricks, fibreglass, plastics, aluminum, and wood can be damaged by applying high-pressure. As such, the best method to remove peeling paint or rust is first to determine the surface material and the type of paint used before starting the job.

You may want to consider hiring a professional cleaning company to remove paint and other coatings from sheet steel, aluminum siding, plastics and fibreglass to ensure these materials won’t pit or warp after pressure washing.


Pressure washing can remove paint from wood, metal, concrete, and other exterior surfaces. The ideal unit to strip paint and rust is a hot water pressure washer with 2000 PSI to 4000 PSI. For suborn stains, you may need to use 3000 PSI to break paint off the surface of the wood.

There are many options available. To remove rust or paint, pressure washers either electric and gas-powered models are good choices. Based on the jobs you have, the electrically powered pressure washerrequires less maintenance but not the mobility you may need.

Gas powered pressure washers are powerful and are ideal for big cleaning jobs since these machines will clean faster. However, a gas powered pressure washer can be too strong for other cleaning applications.

Additional accessories needed are rotary nozzles and a wet vacuum sand. It would help if you also had a high-pressure nozzle for a fine, strong spray, a wide-angle nozzle that sweeps for rinsing and a low-pressure nozzle to apply detergent.
