I wouldnt strip using diamonds,it will ruin the bond to the velcro among other issues. If you want to take that topical off which sounds like it is delaminating in some areas try using 80 or 150 grit honing powder. Far from a perfect solution as the edges will require some stripping and handwork(scraping).It does seem to degrade the topical on the edges making it easier to to remove. We have been successful at getting most of a lighter to medium quality coatings off with out stripper. We do small sections at a time because we always find shiny spots and issues with edges where we need to use stripper or work it by hand. We also do small sections so we can remove the stripper slurry with a cheap vac and rinse. Then we use our extractor to remove any leftover honing powders in the grout lines.
You might consider using the honing powder with a green stripper.
Sounds like a nice job except for the sealing part.
Take freds advice .
Make them sign off that if the stone spalls in the future you wont be held liable.

Genuine concern.

I'd imagine, though, if you pre-wet the plants and exercised meticulous control of your slop with squeegees and wet vac, you should be fine. A helper would work to your benefit here.

I am wondering if removing the sealer mechanically would work. there are plants, grass and a pond that surround the patio. I would think that any stripper would harm the surrounding area.

recommend trying an alkaline based stripper to remove seal then apply StoneCare Central Solvent based sealer.  Be sure to test prior to bidding the job to make sure the seal can be removed with an alkaline based stripper. If this does not remove the sealer you will need to use other more aggressive stripper that may increase the time required to remove the sealer . If you know the name and manufacturer of the sealer contact them and they should be able to tell you how to remove it.
