Floor grinding

[gnxtc2]

For the guys that have done their own floor grinding, thinking back, would have subbed it out or are you happy that you have done it on your own?

I am at that stage where I have to make a decision on my flooring.

If you rent, make sure you get a good grinder with weight and diamonds, not stones. Also, you need a good vac and then damp mop to get all the remaining residue.

Being that you are in my neck of the woods, I can lead you to the right rental place. PM me if you like

I hand grinded my 860 sq ft garage with a diamond grinder and a 7" grinder. It wasn't too bad, just dusty as hell. I wouldn't have liked paying somebody else to do it.

I would do it again by myself. It was done in a day.

Today I rented an EDCO 10" 11 horsepower gas grinder. What a pain in the ***. I would have gladly paid someone to fo that part of this job. The disk did not sit flat to the floor when the machine was in use causing a lot of swirl shaped gouges. My 19 yr old son spent at least 3 hours on hands and knees with a 7" angle grinder with a diamond cup wheel to clean up the mess. He probably has that many more to go tomorrow. I really am starting to doubt the outcome of this whole floor thing right at the moment. I guess if it totally ***** I can put racedeck down in a few years.

I did 850 sqft with a 7" angle head grinder. It wasn't bad after I bought a high grade diamond cup wheel. I used a garden hose with water trickling out to eliminate dust.

An important consideration is the condition of the floor. If it's very even and smooth then a grinder with the right media can do a fairly quick job of it. If it has undulations, high spots, low spots, then grinding can be a real chore.

The grinders with one or more large (10"+) discs will handle smooth level concrete, for the uneven floors look for single head high speed "turbo" grinders, but start slowly, they can gouge easily. Another option for uneven floors are shot blasters, but they're tougher to source, with them also start slowly - bit more of a learning curve.
