If you want the best outcome when you are pressure washing, it’s important take a closer look at your machine’s washing settings first. Cleaning the dirty surface of a driveway, deck, and other parts of your property requires the right amount of force, which is where PSI and GPM come in. These are terms to describe the pressure and flow of the water, allowing you to get the sparkling clean you are looking for. Learn about why PSI and GPM are important for your cleaning needs!
According to Hotsy Water Blast, “PSI stands for pounds per square inch. It refers to the intensity of the pressure with which the machine sprays.” If a machine has a high PSI setting, it’s more likely to lift grime from the surface. Commercial pressure washers have higher PSI’s that can range anywhere from 2,000 to 3,000. For residential washers, they tend to be lower than 2000 and can be handled by the average homeowner.
“GPM stands for gallons per minute. It refers to the flow rate or the volume of water that moves through the pressure washer’s nozzle every minute”, states Hotsy Water Blast. After buildup of dirt and grime has been removed, it needs to be rinsed away. You can adjust the GPM and quickly rinse away any particles or leftover debris. Cleaning detergents may also be added to the water to remove dirt more easily.

For a homeowner, graffiti can be a pain to deal with; if murals are for embellishing, one may say that graffiti are for defacing. Staring at a beautiful building whose surfaces are marred by garish doodles, derogatory epithets, expletives, or other vulgarities is quite unpleasant. Thankfully, with powerful pressurized water, one can kiss all that graffiti goodbye. But how does that all work?
As with most pressure washes, graffiti removal can be an
extremely satisfying thing to spectate. But before spraying all that H2O
on the painted surface, remember to apply some chemical when appropriate. Although
sheer water may somewhat attack the doodles, some product can help soften the particularly
hardened layer of paint. Different surfaces require different chemicals, so
take care to examine whether the graffiti is on a smooth surface like masonry.
Ruining the surface further would be a travesty.
Using only water (with no addition of chemical supplement)
is beneficial to the graffitied surface in that it minimizes the wear and tear
on the surface. One intuitive strategy is to keep the pressure washer nozzle at
a steep angle; blasting the water straight on can make the graffiti sink deeper
into the surface. (Yikes!) As far as water goes, hot water is more effective
than cold water, since raised temperature can make the painted surface expand
and break up the graffiti material. Do be careful with the pressure; a pressure
of 2000-35000 PSI may suit concrete surfaces, but walls made up of materials
like stucco or wood are more fragile!
Graffiti removal is a little bit like reverse graffiti in
that it is a craft that relies on how well a person can trace the curves and
shapes that form the graffiti. (After all, graffiti
means “scribblings” in Italian.) Being surgical and patient is crucial to
success. Mastering the use of high-pressure tips and the rest of the pressure
washer too enhances the job very much. But even if you end up mastering neither,
don’t panic; professionals can help.
The tools of vandalism may keep coming, but thankfully, pressure
washers continue to prove to be a formidable threat to them. Know that you
don’t have to go through graffiti removal alone. The team at Hydra Pressure Washing LLC is out to
help. Simply contact us!
