For most residential pressure washing tasks, a pressure washer with a PSI rating between 1500 and 3000 is generally sufficient, but it's crucial to consider the specific surface you're cleaning and start with a lower PSI setting and increase it as needed. So what square inch pressure washer do I need? For the most common outdoor surfaces, such as wooden decks, vinyl siding and concrete driveways, a pressure washer with a range of 500 to 2000 psi should provide effective cleaning power without risk of damage if used properly. Learning to pressure wash a house is an effective way to ensure that your house looks its best, especially if you want to prepare it to receive a new coat of paint. Choosing the optimal PSI pressure washer involves taking into account the type of surface, its condition, the distance between the nozzles, the accessories used and the degree of cleaning required. When determining what PSI range you want from a pressure washer, there are two general schools of thought.
The pressure that a pressure washer emits is measured in PSI (pounds per square inch), and PSI requirements can vary depending on what you need to clean. If, for example, you want a pressure washer to clean your car, but later you realize that you want to use it to clean your driveway, remove stains and remove paint, PSI's recommendation ranges are very different, and you might be disappointed that yours isn't powerful enough to do the job efficiently. This measures the amount of water your pressure washer emits per minute, and more water equals faster cleaning. When I say commercial, I mean that the system is good enough to make money by pressure washing homes and maybe businesses.
For cleaning residential entrances, a pressure of 1800 psi should provide sufficient pressure to effectively remove dirt, grime, mud, and other debris from concrete, asphalt and cobblestone roads without damaging the surface if used properly. The first is to buy with the pressure you'll eventually want, since you can lower the pressure enough to manage any smaller project and you'll benefit from the “buy it right and buy it once” effect, instead of upgrading later. Use the equipment you have and go wash some houses, spend a little on marketing instead of buying equipment now, make sure it's intelligent marketing equivalent to your current situation, prices with marketing, advertising can quickly get out of control. Now place your thumb on the end of the hose and you can wash away any lumps of soil from the entrance or sidewalk. For example, much less pressure will be needed to clean dirt and salt from the vehicle than to clean oil stains from the garage floor.
On the other hand, if you're never going to exceed 2500 PSI for your projects, you can save some money if you choose a 2600 PSI pressure washer instead of a 4000 PSI pressure washer. When washing vinyl, wood or fiber cement siding, a pressure of 1800-2000 psi should provide enough cleaning power to remove dirt, mold, fungi and other accumulations. While water pressure provides the power to break up stains and dirt, the volume of water is what removes that broken dirt.
