Likewise, people ask, can you damage concrete with a power washer?

The quick answer is yes, power washing can degrade a concrete surface. You can notice visible damage from water pressure at the level at which even light-duty power washers can operate. Therefore, if you aren't careful, you can cause irreversible damage to your driveway or patio.

Subsequently, question is, how long after power washing can I seal concrete? After the concrete has sealed completely, pour your sealant into the paint pan and begin applying on the surface with your paint roller. Use the same motion as before, working your way down the driveway. When this process is completed, you must wait 24 hours before parking any vehicles on the surface.

Beside above, how often should you pressure wash concrete?

That is why most professionals agree that your driveway should be pressure washed at least once a year. This will keep the grime off the surface and you can keep washing it per your need and time over the year yourself, to keep it in the best shape.

What is the best chemical to clean concrete?
