What is the best PSI for pressure washing a house? When you pressure wash your home there are a few things that you need to consider.
One of those is the flow rate, and you also need to think about what detergent and nozzle type you want to use. Today we cover all of that and more with guest expert Mark William.
What PSI Is Good for Pressure Washing A House
“Every time I pressure wash my home, it doesn’t look like I have cleaned it, let alone the sparkling look. Is there anything wrong with my pressure washer, or I make the mess each time?”
Questions like this are common among homeowners, as many of them fail to clean their homes despite many efforts. Sadly, the numbers of complaints aren’t ignorable.
Improper washing is mainly a result of the lack of pressure from your washer. It often happens because you are probably running the machine under pressure, or the engine isn’t powerful enough. So, before you clean your house or shop for a pressure washer, you must know what PSI is good for pressure washing a house?
The suitable PSI range for pressure washing a house
When you clean home with a pressure washer, there’re lots of things you need to consider. One of those prime concerns is what kinds of materials and surfaces you are going to pressure wash. It’s essential that a home has a broader spectrum when it comes to cleaning substances, and the pressure will vary accordingly.
For instance, cleaning regular dust from a concrete floor requires less PSI. Whereas garage cleaning will need much higher PSI outcome.
Also, you have to note that higher PSI doesn’t always guarantee better cleaning. There’re other factors involved, too, like the water flow rate. Or what cleaning agent you are using. We will discuss them in the latter half of the write-up, but for now, let’s get back to the PSI level.
2500-3000 PSI Works Perfectly
Apparently, for pressure washing your home around 2500-3000 PSI works perfectly. But as we told you that it would vary from material to material and also the amount of dirt you are going to clean.
Here’s an approximate list of PSI you need to clean different house objects: Concrete floor or stucco: Around 2500-3000 PSI. Garage gunk: 2500-3000PSI. BBQ Grills: 1500 PSI. A driveway made of asphalt: 3000 PSI
This is an estimated PSI value for pressure washing your home correctly. You must be clear by the time now that most of the home cleaning requires around 2500 PSI. So, when you decide to buy a pressure washer, choose one with about 2600 PSI instead of 3000 PSI the rest power won’t be any need for you. Also, why should you pay for the extra PSI when it doesn’t come useful for you?
Selecting the Appropriate Water Flow Rate
The PSI from the pressure washer won’t clean your home surface by itself. The water coming out from the appliance has an even more crucial role to play.
The water pressures help to break the chemical bonds of the dust and grime, whereas the water flow or GPM sweeps off the dirt and debris away.
With high pressure and low water flow, your cleaning task will become tedious and challenging. Similarly, less pressure and high water flow will soon turn your home into a swimming pool. So, you must keep a balance between the two.
A Higher Flow Rate Makes the Work Swift
Also, with a higher flow rate, which means more water coming from the pressure washer nozzle makes the work swift. We have considered all these issues and tested hands-on to pile up the following data of GPM for you.
A 2.00-2.50 GPM for most objects. 2.50-4.00GPM for difficult stains and gunk in the garage, patio, and driveways.
So, the next time you pressure wash your home, keep this GPM data in head and use it to increase the cleaning efficiency of your home. Also, make sure the water you are using is clean; otherwise, you will have to do the job twice.
Some Useful Tips to Pressure Washer Your Home
Pressure washing your home is fun when you know the tricks. And if you don’t know the proper way, the cleaning experience can soon turn upside down. And we want you to always remain on the sunny side of the fence.
So, we have compiled the following tips for you to pressure wash your home with increased effectiveness.
Gas vs. Electric Pressure Washer
First, choose a pressure washer you are comfortable with working. Experts suggest using a gas-powered pressure washer for cleaning home since it has higher GPM.
The gas-powered pressure washers will complete the task 2X faster than the electric ones. But, an electric pressure washer may delay your job but can be handheld and cause less work fatigue.
The nozzle has a vital role when it comes to home cleaning. You should pick a nozzle tip with a 25° to 40° angle. These angles are designated for medium-duty pressure washers that you use at home.
Then choose a black nozzle suitable for soapy water if you are going to use detergent for the pressure washing. Also, you will require a wand to reach the nook and crannies of your home for perfect cleaning.
A brush attachment will come handy to sweep away the soapy water and grime quickly. It will make the job much more comfortable. The best thing is that the brush attachment won’t cost you much.
Choose Your Detergent
Without using detergent, you will risk damaging the stucco or home paints with higher water pressure and flow. When you pick the right cleanser, your washer will need less GPM and PSI to sweep off the debris.
It is because the detergent will break down the chemical bonding of the debris easily.
Also, whenever you pressure wash, wear protective goggles to safeguard your eyesight. Also, start washing from at least 3 ft distance and slowly go closer to the object. It will help you find the right spot for comfortable cleaning without damaging the surface.
Having a quality pressure washer is fun. You can perform extensive cleaning jobs with it in a few moments.
And pressure washing your home is one of them. The task will become even more enjoyable when you choose the right PSI and GPM.
So, the next time you think of pressure washing your home, don’t forget the tips and suggestions; we bet you won’t be disappointed.
