What is the ideal pressure for washing concrete?
The ideal pressure for washing concrete depends on the type of concrete, its age, and the level of dirt or staining. A general rule of thumb is to start with a lower pressure setting (around 1000-1500 PSI) and gradually increase as needed. This approach helps prevent damage to the concrete surface. However, for more stubborn stains or heavily soiled areas, a higher pressure setting (up to 2000-2500 PSI) may be necessary.
It’s essential to note that using excessively high pressure can damage the concrete, especially if it’s old or poorly maintained. Therefore, it’s crucial to test the pressure setting on a small, inconspicuous area before applying it to the entire surface. Additionally, the type of nozzle used can also affect the pressure and distribution of the water stream, so be sure to choose the right nozzle for the job.
Can a 2000 PSI machine really get the job done?
A 2000 PSI machine is a popular choice for cleaning concrete, and it can be effective for many tasks.
