Is Power Washing Bad for Concrete

Is Power Washing Bad for Concrete?

Power washing, also known as pressure washing, is a popular method of cleaning outdoor surfaces, including concrete.


However, a question arises among homeowners and business owners: Is power washing terribly for concrete?


In this blog post, we will explore the various factors that can cause damage to concrete during power washing and what precautions can be taken to prevent it.


How Can a Pressure Washer Harm Concrete?

A pressure washer can damage concrete by using water pressure that is too high or by holding the nozzle too close to the surface being cleaned. 


The pressure can cause cracks or pits in the surface of the concrete. The water pressure can also dislodge small particles from the surface, leaving it more susceptible to damage from other sources.


Why Would Concrete Be Easy to Damage?

Concrete is a porous material that can absorb water, oils, and other substances.  


When pressure washing, these substances can be forced deeper into the concrete, causing more damage and staining. 


Also, concrete can be weakened by exposure to extreme temperatures or chemicals, making damaging it easier.


The Status and Quality of the Concrete

The quality and condition of the concrete will also play a significant role in how it reacts to power washing. 


High-quality concrete poured correctly and appropriately cured will be less likely to experience damage.


On the other hand, low-quality concrete or concrete that has been poorly maintained will be more susceptible to damage from power washing.


The Age of the Concrete

Another factor that affects the safety of power washing on concrete is the age of the surface. 


Newly poured concrete requires a waiting period of at least 28 days before it can be power washed. 


This waiting period allows the concrete to cure and harden fully. 


It newly poured concrete can damage the surface and reduce its lifespan.



In conclusion, power washing can only harm concrete if done correctly. 


The best way to avoid damage is to use a low-pressure setting, hold the nozzle at least 6 inches away from the surface, and avoid power washing newly poured concrete. 


Additionally, regular maintenance and care of concrete surfaces can help prevent damage and extend the surface’s life. 


By following these guidelines, you can safely and effectively clean your concrete surfaces using a power washer.
