Before you buy any pressure washer for yourself, you should know the strength of that power washer. The dirty and grimy house’s external surfaces need higher pressure.

Various surfaces need diverse cleaning pressure. Cleaning the concrete needs almost 3000 psi. Cleaning decks need pressure between 500 and 600 psi. Higher pressure can damage paints or some surfaces. Before you clean any surface, check the pressure you will use to limit damages. If you aren’t sure of the exact pressure needed, start cleaning with low pressure and increase it slowly.

Adjust the pressure of the washer to appropriate levels before cleaning your surface. Using the washer t clean isn’t an easy task. The washer forces water streams through the nozzles at more than 60 times more pressure than an average garden hose. If you don’t use it well, it will destroy the surfaces you are cleaning. It’s easy to damage your car paint or the paved driveway. To clean concrete surfaces, you need high psi machines of about 3000 psi. Decks need between 500 and 600 psi rating. It’s thus essential to choose a machine that will match the surface you are to clean.

What’s the pressure for cleaning driveways?

Generally, you need a pressure of about 3000 psi to clean a driveway. The pressure you use must have a flow rate of about 3 GPM. If your driveway has stains, apply a degreaser.

You need to have better water pressure and flow rate for effective driveway cleaning. Remember to abide by the preventive measures for safety. The recommended pressure is 3000 psi with a 3 GPM flow rate if you need to remove any filth. The faster the water flow rate per minute in your nozzle, the quicker the cleaning process.

Do you want to clean office driveways that can lose paint from high pressure and GPM? Instead of using the machine with high ratings, use a 1.8 GPM and 1800psi machine. The machine will be gentle on the delicate driveway but clean it better.

What’s the psi for cleaning decks?

You need the lowest pressure rating machine to clean decks. The machine should limit damages caused by high pressure. It should also be effective. You will need between 500 and 600 psi for softwoods like cedar and pine. For hardwood, you need between 1200 and 1500 psi. You need to be careful with the high pressure not to damage the deck surfaces.

Though it appears to be an easy task to shoot and point water, the process has some technicalities. Washing decks using wrong washers or settings will bring more irreplaceable damage to the wood. It will turn out to be an expensive method. You need to use the correct Gallons Per Minute (GPM) and psi rating for effective cleaning of any deck. Power washers can curve into bricks and gently remove all the cobwebs and some stains.
