Help With Bid -- Stucco on Concrete

[HighTide]

I have been asked to provde an estimate for cleaning up the stucco that has dried on the concrete and brick pavers of this home that just had all the house siding redone with new stucco. The front porch is the worst with the brick pavers showing spotting that can be chipped or scraped off. Will 3,500 PSI get any of this off or will a chemical be required to do it? If the front porch concrete can't be returned to normal, what are other options to get this home sale ready? Thanks for any advice.

This application sucks... I have had it and made several trips back and forth testing different chems, at different strengths, with different dwell times. I worked with EacoChem using both NMD80 and Safe Restore. My app was similar with mortar dried on the pavers.

I tried NMD80 starting at 8:1 and worked my way to 3:1 with lengthy dwell times to see no improvement. TomTuscon had a similar post. I asked him if he had any luck but never received a response.

Let me know if you have any success...

We just did a very similar commercial project, we were lucky enough to just be able to use a turbo tip at 3200 psi and 6gpm, you have to kind of work it at an angle to get under it a bit. We did stucco and spilled cement.

If you can try to let the PM know that results may vary, just to cover you in the long run.

Good luck.
