Can Pressure Washing Crack Concrete? – Your Quick Guide

Can power washing crack concrete? This is a vital question, as using too much pressure during washing risks damage to many outdoor materials. However, you might wonder if this includes concrete! Since cars can drive over concrete, can power washing risk damage including cracks or etching?

The short answer is yes, power washing can crack concrete when done incorrectly. High-pressure water streams can crack or etch concrete and dislodge aggregate. It can also peel paint! However, when done properly power washing offers excellent concrete cleaning.

This is just a quick overview of the question, can power washing crack concrete. To find out more, keep reading! Also, never hesitate to contact a power washing contractor for needed cleaning on your property. They’re usually happy to prepare free quotes and explain your best cleaning option.

Can Power Washing Crack Concrete and Other Outdoor Materials?

Power washing can potentially crack concrete if not done properly, as said. The force of pressurized water used for power washing can be strong enough to damage concrete. This is especially true if it’s held too close to the concrete. Check out the most common reasons why power washing could lead to concrete cracking in a bit more detail:

  • Note if the power washer is set to a very high pressure setting or if the operator uses too much pressure. This can weaken the surface of the concrete and even cause cracks and chips.
  • Holding the power washer nozzle too close to the concrete surface can focus the water pressure in a concentrated area. This increases the risk of cracking or dislodging aggregate.
  • Older concrete is more susceptible to cracking under high-pressure water.
  • Repeated power washing over a short period of time can gradually wear down the surface of the concrete. This makes it more prone to cracking.

In summary, power washing can crack concrete if not done carefully. It’s important to use the right equipment, pressure settings, and techniques to clean the concrete without causing damage.

How Do You Avoid Cracking Concrete During Power Washing?

To minimize the risk of cracking concrete while power washing, it’s vital that property owners consider their technique. Adjust the pressure setting on the power washer to an appropriate level for the surface you’re cleaning. Lower pressure settings are usually safer for concrete.

Also, keep a safe distance between the nozzle and the concrete surface. A general guideline is to keep the nozzle at least 12 to 18 inches away from the concrete. Use a wide spray pattern instead of a narrow, concentrated stream to distribute the pressure more evenly.

Moreover, you might test the power washer on a small, hidden area of the concrete before starting. This can ensure that the pressure isn’t causing any damage. It’s also good to cover nearby plants, sensitive surfaces, and items that could be damaged by the water or debris.

Should You Treat Concrete After Power Washing?

Yes, contractors often recommend treating concrete after power washing. This will protect and maintain its appearance, durability, and longevity. Note, power washing can remove dirt, grime, and even some types of stains from the surface of the concrete. However, it can also strip away a thin layer of the concrete’s protective coating and leave the surface more porous.

In turn, treating the concrete after power washing helps to seal the surface, prevent water penetration, and enhance its durability. It can also keep it cleaner overall, blocking dirt and grime from concrete pits and pores. Note some common treatments for concrete you might consider after power washing:

  • Applying a concrete sealer is one of the most common post-power washing treatments. A sealer creates a protective barrier that helps to prevent water, stains, and contaminants from penetrating the concrete. It also enhances the appearance of the concrete by giving it a glossy or matte finish.
  • If you want to change the color of your concrete or enhance its visual appeal, consider staining it. Stains and colorants can add depth and character to the surface.
  • If you notice any cracks or damage on the concrete surface after power washing, repair them promptly. Cracks can allow water to seep into the concrete and cause further damage over time. Fillers and other repair methods keep out that water, protecting concrete from damage.
  • In some cases, especially if the concrete has been significantly worn down, you might consider resurfacing the concrete. This involves applying a thin layer of concrete overlay to restore the surface’s appearance and functionality.

The specific treatment you choose depends on the concrete’s condition and what you want it to look like. For instance, some sealants offer a glossy, slick look while others provide a matte appearance. Overall, treating concrete after power washing can help protect the material. It maintains the appearance of your surfaces, and extends the lifespan of the concrete as well.
