Did you know that pressure washing machine can produce pressure of over 30, 000 psi? Power washing or pressure washing is the spray of pressure water to remove dirt, dust, grime, mud, mold, loose paint and chewing gum from objects and surfaces such as vehicles, concrete surfaces and buildings. The equipment produces pressure between 5 and 200 MPa (750 and 30, 000 psi) and above.
Using hose to clean dirty surface and rinse dirt is good but it cannot replace power washing machine. Washing with pressure machine removes growth and buildup that lead to decay, structural materials, coating erosion and deep stains. The washing with pressure machine is more involving than getting machine and washing grime. It is not a difficult process.
Knowing the best technique and washing products are important to efficient and effective results. This will also prevent damage to self, surface or the machine you’re using.
GPM and PSI
Power of pressure washing machine is measured by flow of water know as Gallons per Minute (GPM) and pounds per square inch (PSI). The high the GPM, the fast the rinsing and cleaning process because the amount of water released is increased. The low the GPM, the cleaning process time and PSI increases which can led to damage on the surface.
Using the right PSI is important because the higher the PSI, the higher the water force on the surface. Too much PSI can cause damage to most surfaces. The right GPM and PSI is critical for the best results on the surface and machine.
Types of pressure washers
An electric powered washer is light and convenient. They are quieter, portable and cheaper than machine powered by gas, making them best for residential use like removing dirt and stain from concrete or cleaning fences. They have no exhaust fumes therefore can be used inside the house.
Gas powered washer produce more water pressure compared to electric, over 3000 PSI. They are used in jobs such as intensity cleaning and cleaning deep concrete. This kind of washing machines produces harmful fumes and loud sound when running.
Significance of nozzles while pressure washing
Use of the wrong spray tip or nozzle for pressure washer results in costly damages and other problems. Concrete scarring damage, damaged wood, broken seals on window and composite decks is common with wrong tip use. Mildew and mold issues are caused by intrusion of increased pressure water. Different type of work requires different pressure nozzles. Velocity is increased by restriction of the water flow.
How to pressure wash
To pressure wash you need to start cleaning from 4 feet away, going nearer as required. Work on little sections always. Going away from surface when pressure washing decreases the pressure regardless of selection of nozzle. To wash stains or tough buildup, you should increase pressure by moving the spray near the surface. Use a lower-degree tip if it doesn’t work.
When working on vertical areas, work from bottom upward using cleaning solutions. When rinsing start from top down. Don’t spray siding surfaces because it can lead to mildew and mold or driver water under the surface or dislodge panels. Store the pressure washing equipment properly to avoid damage.
Rinse pressure machine before storage. Corrosion on the machine parts can be caused by some products if not washed well. Use products which are safe to both the surface and the pressure washing machine.
If you want to clean and maintain your home pressure washing will do a great job. A washer that meets your washing needs will do a fantastic job in pressure cleaning both on the inside and outside of your premises. For more information, click here
