I originally produced this video to show how to prepare a driveway for the F9 Rust Removal process but thought it would be good for some of you to see how to properly power wash any driveway.
There are a few techniques you can use if you watch closely, like how to keep the hose off your surface and behind you at all times. This eliminates the need for a hose guy.
I also use a double-direction pressure washing technique, going faster on the 2nd time over. This helps to reduce any possible surface cleaner lines and makes everything come out a little cleaner.
Use of a good degreaser allows us to adjust the Landa Water Jet up higher so the impact of the tip to surface spray is lower, yet wider… which allows me to work faster while reducing the possibility of damage to the concrete.
If you have any questions, feel free to post them here.
Perhaps the driveway cleaning you do in CA is a bit different from what we do here in NC. We have to walk at about 1/4 that speed and with each pass, it’s like drawing white chalk on a black chalkboard. Even then, we usually have to follow with bleach to kill the residual mold. I couldn’t even tell a difference between the before and after cleaning of the driveway in this video.
You are correct, Rob. Pressure washing is much different depending on your location, the psi of the concrete, the stains you are trying to remove and if you have mold etc. In this video the concrete did not have any oil or mold, but did have an amorphous paste layer from the customer using a HCL product to try and remove their orange battery acid burn.
BUT… this is also the way we clean all of our driveways out here, regardless of the contaminants. If there is an oil stain we will follow up with BT-200, an enzyme, rekrete or other types of residual oil stain cleaners.
Mold removal is an entirely different process. We don’t have much mold because it’s too dry in Palm Springs, CA.
Below is a video of before and afters using the F9 process
