How does Concrete Sealer Work? 

Concrete sealers are designed to provide a protective barrier against stains, moisture, and other elements that can cause damage. However, over time, these sealers may wear off or become discolored, requiring removal and reapplication.

Why Power Washing Removes Concrete Sealer

Power washing utilizes high-pressure water jets to forcefully remove dirt, grime, and even stubborn sealant from the surface of the concrete. The force exerted by the water stream combined with specialized nozzles helps break down and dislodge the sealer particles.

Tips for Power Washing Concrete Sealer

If you are doing your own Power Washing job to remove concrete sealer, here are some nifty tips and tricks you can use to get the most out of your power washer. 

Verify Your Equipment is Up to the Task

It is important to note that not all power washers are suitable for this task. Using too much pressure or incorrect techniques can potentially damage the underlying concrete surface. Therefore, it is recommended to hire professionals who have experience in power washing specifically for concrete sealer removal.

Use the Right Distance and Angle 

Another critical aspect to consider is the distance and angle of the power washer nozzle. Holding the nozzle too close to the concrete can etch the surface, leaving permanent marks. 


A good rule of thumb is to keep the nozzle at least 12 inches away from the surface and to use a sweeping motion. This method ensures a uniform cleaning pattern and reduces the risk of concentrated pressure on one spot. 

Use a Fan Tip 


Always use a fan-tip nozzle instead of a zero-degree nozzle. The fan tip spreads the water over a larger area, reducing the force of impact on a single point. 

Avoid Direct Sunlight 


It’s also advisable to avoid power washing in direct sunlight. The heat can cause the sealer to soften, making it more vulnerable to damage. Opt for a cooler part of the day, such as early morning or late afternoon, for your power-washing endeavor.

Consider Hiring an Expert 

When performed by experts using proper equipment and techniques, power washing can be highly effective in removing sealer from concrete surfaces. It offers a convenient and efficient solution for restoring the natural beauty of your concrete while preparing it for resealing if desired.
