Pressure Washing Tips For Concrete

Concrete is an easy surface to pressure wash, but it can also be damaged if done incorrectly. Using the wrong tip or too much pressure can damage the concrete and cause it to become etched. Thankfully, there are several pressure washing tips that will help you safely clean concrete without damaging it. Read on for a few of these tips to make the process go as smoothly as possible.

First, always read the manual that came with your pressure washer. It will show you how to connect the wand to the pressure washer’s water supply. You can also learn about the different nozzles that are available. Low-pressure nozzles are best for applying detergent, while high-pressure ones should be used to rinse. Always remember to follow the manufacturer’s instructions when using a pressure washer, since you don’t want to damage your concrete.

Before you begin pressure washing concrete, be sure to first remove any oil stains. Oil stains can be especially difficult to remove. A solution of baking soda or cat litter can soak up excess oil without harming the surface. Apply the mixture to the stains and leave it for ten minutes. Then, rinse the surface thoroughly with a pressure washer. Oil stains and rust stains usually come off easily, but paint stains are harder to remove. You may have to repeat the steps to remove stubborn oil stains.

If you’re using a light-duty power washer, remember that high water pressure can cause permanent damage to the concrete. In addition to removing sealers and coatings, it can also break down the top layer of concrete, leaving etch marks. Since the top layer of concrete is where the majority of its strength is located, removing this layer can cause it to deteriorate.
