The Dos and Don’ts of Pressure Washing Concrete

Are you looking to revitalize your concrete surfaces with a thorough pressure washing? Before you dive in, it’s important to understand the dos and don’ts to ensure a successful and safe cleaning process. By following these guidelines, you can achieve professional results while avoiding potential damage to your concrete surfaces. Let’s explore the key dos and don’ts of pressure washing concrete.

Dos of Pressure Washing Concrete

Use the right pressure and nozzle

When pressure washing concrete, it’s important to use the right pressure setting on your machine. Using too high of a pressure can damage the surface, while using too low of a pressure may not effectively clean the concrete. Additionally, using the correct nozzle for the job is crucial. A narrow, high-pressure nozzle is best for tough stains, while a wider, lower-pressure nozzle is better for general cleaning.

Test on a small, inconspicuous area first

Before diving into pressure washing your entire concrete surface, it’s a good idea to test the pressure washer on a small, inconspicuous area. This will allow you to see how the surface reacts to the pressure and adjust accordingly. It’s better to be safe than sorry when it comes to potentially damaging your concrete.

Work in sections

To ensure a thorough and even clean, it’s best to work in sections when pressure washing concrete. This will help you focus on one area at a time, making sure each section receives the proper attention. Working in sections also helps prevent streaks or missed spots, resulting in a more uniform finish.

Don’ts of Pressure Washing Concrete

Don’t use excessive pressure

Using excessive pressure when pressure washing concrete can actually do more harm than good. It can cause damage to the surface by etching or chipping away at the concrete. It’s important to use the right amount of pressure for the job to avoid costly repairs in the future.

Don’t neglect safety precautions

Safety should always be a top priority when pressure washing concrete. Neglecting safety precautions can result in serious injuries or accidents. Make sure to wear protective gear such as goggles, gloves, and closed-toe shoes. It’s also important to be mindful of your surroundings and avoid spraying water near electrical outlets or wires.

Don’t hold the nozzle too close to the surface

Holding the pressure washer nozzle too close to the concrete surface can cause damage by etching or gouging the concrete. It’s recommended to keep a safe distance of at least a few feet away from the surface. This will help ensure a thorough clean without causing any harm to the concrete.


In conclusion, pressure washing concrete can be a highly effective way to clean and revitalize your outdoor surfaces. By following the dos and don’ts outlined in this article, you can ensure that you achieve the best results without causing any damage. Remember to always test a small area first, use the right equipment and techniques, and prioritize safety at all times. With proper care and attention, your concrete can look fresh and new for years to come. So go ahead, grab your pressure washer and get ready to see the transformative power of a good cleaning session!
