Painted sidewalk: washed or dammaged? (pics)

We will be pressure washing the sidewalk of a shopping center as soon as I am sure, we will not do more damage than cleaning. The side walk has been previously painted with this: "DYCO Paints TUFF-COAT Stain Enamel" and it has already started to peel off at some spots. The PM wants to know if the paint will peel off all over the sidewalk prior we do the job. I was thinking to hit it with max heat and less than 2000PSI, so I could avoid the paint to peel off as much as possible. I will make some tests with different size nozzles (as soon as they arrive). Below you will find some pics, please let me know what do you think and what would you suggest?

Thanks Again!
 
We've got a property like that just now... whole property had a revamp, sidewalks were greasy, stained and in real bad condition - so they painted them, looked great for a couple of months but paint was flaking with foot traffic and 'grease tracking' at restaurant entrances.

Told PM that we can not pressure wash with same methods and to same standard as at other properties because paint will just flake off and make property look terrible. It's frustrating leaving property knowing that it is not up to par.
 
Hey Dimitar, do yourself a favor and put down a light coating of degreaser let it sit a bit and run cold water over it with reduced pressure.

I agree, chemical action is what is needed here, if you are going to use a surface cleaner you would have to experiment and dial in the pressure needed, but you have a flow type unloader, somewhat of a disadvantage. You may still be able to warm the water, for better cleaning FOX.
 
I did a building that had 4 entrances that were painted, you have to reduce the pressure a lot or the pressure will remove a lot of the paint.

Reducing the pressure on a surface cleaner is still a lot faster than wanding the whole area.

Nick do you remember "Malls Corner" just outside of Atlanta? It had all the twist and turns in it and it was painted as well (had the big HH Gregg store)

I dont think I ever did that one. Maybe who the hell can remember anymore.:neo:

Nick, I'll try that. What degreaser do you use in cases like this?
The whole surface is 9600 sq ft.
Thanks!

Hey Dimitar, I only use a Butyl based degreeser, it's pretty stong stuff but you can dilute it down for you specific need's. It dont take a strong mix to remove stains from a painted surface so I would just do a 50/50 mix then downstream it on.
 
Soap and RINSE. Let the soap take off the surface layer of the paint and it will look like new, then Stay Away with the nozzle.

Soap wont bring up the heavy stains and oil in the paint like degreeser will. :no:

I was thinking to spray it with the fatboy pump and then to lower the pressure to 1500PSi with bigger nozzles.
 
Soap, degreaser, I mean the same thing. That would be my plan - let the chem clean and then rinse - you'll know immediately how close you can get with the spray. You may or may not be able to get some gum with the low pressure.

If you come right out of a chemical tank with a pump then I would dilute it even more. I will see ya soon, I have a Demo in Miramar on the 14th then I will be in Ft Laurderdale.
