The second photo you showed wasn’t delamination, it was concrete failure, which grinding, might expose by removing all the loose concrete, then obviously patching as necessary. But it also may just skim over that and you will have that problem down the road. even with grinding. A shot glass would do more justice to remove that spalling. Big drawback of shot lasting is the overlap lines or zebra stripes as i’ve heard them called. If you’re coatings thick enough, it will hide that but you really need to pour it down almost as a leveler . It would be nice to know the grit you are using for your grinding. I know our initial passes are like an 18/20 then we go to a 30/40 which may be good enough for a sealed concrete. Then our next step is 100 grit That is also a good finish for a seal.

Thanks for the comment! The final grit of the diamonds would depend on what type of coating/flooring you plan on applying in the end. For high build coatings or broadcast flooring, the 18/20 is all you should need. If it's a thin coating or a stain & topcoat system, you would want to clean it up with the 30/40. There might be times that you'll need to hit it with something in 60/80 range if there are still a lot scratches from the 30/40's. I would not recommend going any higher than 80 grit because it can start to close up the pours of the concrete. Hopefully this helps! Thanks for watching Deco-Crete TV!!
