Hey Guys,
Looking for some help on my floor.
Long story short - we rented an Edco floor grinder and it was WAY too aggressive. We returned it and rented a "concrete floor prep tool" (American Sanders) with a diamond coated flap disk on it. It worked better - smoothed out the damage the Edco left and overall did what we needed - prepped the floor and gave it a nice profile for epoxy. wish I would have rented this first.
The problem now is I have some areas on the floor, say 1/4 of the garage, where the concrete is rough/not smooth. It almost looks spalled. Certain areas have part of the original "cap" and then adjacent to it rougher concrete that is maybe 1/32 to 1/16th of an inch lower.
I've tried hand grinding these areas with a cup disk and hard masonry disk - but again it is too aggressive and removes too much material (much like the Edco). A 40 grit flap disc was better at smoothing it out and easing the transitions but it certainly isn't as smooth as the other area of the floor
The finish: Armorseal 33 prime, 650 epoxy, rejection broadcast of flakes, 650 epoxy and then HS topcoat the floor - a solid finish - but obviously prep is everything and I don't want to put a great finish that's just going to show a poorly prepped floor.
I come from a wood finishing background, so I may be over thinking how smooth this needs to be (if it catches your finger you can see it type thinking) - I don't want these imperfections to coming screaming out when light hits them though
what do I need to make this concrete right?
The first picture, along the wall, is the worst area - the second and third pictures were after I hit some of the problem areas with the 40grit flap disc. better for sure - and I can do this where it is needed, just want to make sure that is what's needed.
