Fortunately, pressure washers are available in the market, and they can make cleaning jobs look easy. Many questions arise in the mind of users when they are buying pressure washers. One of them is what size pressure washer do I need for cleaning concrete. Let’s discuss it in this buying guide.
Minimum Pressure & Flow For Concrete
The ideal PSI for cleaning concrete has to be at least 3000 PSI. The 3 GPM is the minimum flow of water rate, which you should consider while buying the best pressure washers. If you want to clean the building from the outside area, you will not like that the paint should be harmed. In this situation, look for a pressure washer, which boasts of 1500 PSI, and it will deliver 1.8 GPM. If you want to clean the usual debris or dust, you should cover the surrounding walls first and then startup with the cleaning.
Detailed Cleaning Techniques
You need to have a hot pressure for water while cleaning the concrete or brick surfaces. You are advised to use a 25-degree nozzle, which will suit best for cleaning concrete from driveways, patios, and pool areas. Some people prefer a 40-degree nozzle, but for handling that, you need to take care of yourself. You should keep yourself away from the pressure washer when using a 40-degree nozzle.
If you are planning to clean off the concrete, using a degreaser should be a wise option. You can scrub the concrete using a brush while other additional accessories can be used for cleaning it. The high powered pressure washers are considered to be the right choice for cleaning concrete as they contain more of a degreaser. If you are interested in using a natural degreaser, you have the option to try out the vinegar. You have to add the degreaser in the detergent tanks, and concrete will sweep away instantly. The vinegar can blend into the pressure of water quite quickly. If you are working manually, you can use baking soda powder. It isn’t recommended to put baking soda inside the pressure washer as it will damage the machine.

When you are using a pressure washer with 2500 PSI, it will rip the concrete; however, you have to make sure that the surface will not tear up. You also need to stay away from the pressure washer, as it can cause injuries. You should use the light spray as the flow of water should be moderate enough. The concrete which contains Stenciled or imprinted should be dealt with carefully. Otherwise, the pressure washer can damage the design of the surfaces. If you are trying to remove coating or sealers even then, you have to be careful. If you seal your concrete, you can save it from getting damaged.
