Preparation

Before starting the pressure washing process, it’s important to prepare the area. Clear away any loose debris, like leaves or dirt, and apply a suitable cleaner or detergent to the surface. This pre-soaking helps loosen the dirt and makes it easier for the pressure washer to remove stains.

Positioning the Nozzle

Proper nozzle placement is crucial for effective cleaning. For concrete surfaces, a wide-angle nozzle, such as a 25- or 40-degree tip, is typically recommended. Hold the nozzle at a consistent distance from the surface to ensure an even and thorough clean.

Maintaining the Right Distance

The distance between the pressure washer nozzle and the concrete surface is essential to prevent damage. Typically, a distance of 6 to 12 inches is recommended. Holding the nozzle too close can cause etching or gouging, while keeping it too far may reduce the cleaning power. Experiment with different distances to find the sweet spot for your specific pressure washer and concrete surface.

Safety Precautions

Safety should always be a priority when pressure washing, as it involves powerful equipment and potential hazards. Follow these safety precautions to protect yourself, others, and the concrete surface.

Wearing Protective Gear
