Hey DC - love your series on garage floor renovations. Quick question - my floor has an area with a pretty steep grade towards the back wall. Would you recommend spending more time grinding down the surface in that area, or will the coating itself have some leveling properties? I would plan on doing the PolyArmor system recommended in your other video. Thanks!
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!!

Thanks for the comment! We recommend our Quik Fix product for filling cracks and saw cuts. I'll leave a link to our how-to video and the page on our website.

Thanks for the comment! It took around 4 hours to grind this floor. That was with one 8" walk behind grinder and a 4" angel grinder for the edges. You could speed this process up with a second person working on the edges while the other you grind the main part of the floor. A larger walk behind grinder would also speed things up.
