anyone have experience concrete floor grinding?

[hoshanaeckhart]

After considering epoxy and cement-based leveling for my shop floor, I'm now thinking maybe all I need is to grind it and seal it. I can rent an Edco 2-wheel grinder locally for $150/day. I figure I'd need to remove about 1/8" on average over the 400 square feet to get it as smooth and level as I'd like concrete grinding cape coral. The manufacturer says this grinder can remove 1/32" over 350-500 feet per hour concrete grinding brisbane. Four-plus hours of grinding sounds like a bit of a slog, but if it turned out well, probably worth it. I got 'resurfacing' (grind, level, epoxy coat) estimates from $4.50 to $7.50 per square foot.

Does anyone have experience and advice about grinding concrete floors?

I had to grind down and smooth out the old concrete subfloor in my old house. We removed this ugly tile in half the house which left all sorts of mortar, and the kitchen subfloor for whatever reason looked like the face of the moon.

This was 15 years ago now, but I rented the same machine you mentioned above and did the work myself. A few things I learned:

a) It took off years of my life from all the dust. Use water, it helps keep the dust down but damn.
b) It's a hell of a lot of work
c) I put a big heavy toolbox on top of the machine so I didn't have to push down as hard
d) Make sure you get the right grinding discs for the bottom of the machine. The ones that cut quickly leave grooves, so you want to use the harsh ones to take off whatever material you need and then switch to something that smooths afterward.

The smooth towards the glass door is after the first pass


first pass on the left, old on the right


after. We didn't need a mirror surface since I was putting down wood floors, but it was smooth.

When I moved into my house it was 15 years old and I wanted to epoxy the garage floors (2 car garage). Cleaning and acid etching just wasn't doing the trick to prepare the surface. I rented a grinder from HomeDepot and it took me roughly 6-7 hours to get a result I was happy with. It had a water hookup so the dust was cut to a minimum. I then did a DIY epoxy coating thats holding up great.

How uneven is it? Could just put down Racedeck over the existing floor.
