Well it has begun

[newgarageguy]

Well I started the process of grinding off the old junk half painted floor the previous owner did in my attached garage. Even with a 10" grinder the work wasn't what I would call easy, oh and teaching myself how to use this thing was an experience. There are some spots that this thing just would t get as I realize they are too low and I would really have to take a lot of material off to get to. What do you guys recommend just a hand grinder with a similar disk? Also I'll be doing an epoxy on this floor not to sure which one I'll go with it's approx 550 sq ft. And I usually use this garage as the entrance to my home. Since my front door is a bit out of the way of my drive way.

Is your wall concrete?

Home Depot has a RIGID diamond wheel that fits a 7" grinder and it cuts into concrete pretty well. It runs about $80 for the wheel. If you don't have a grinder, Harbor Freight has some nice ones that hold up pretty well. Or, rent one. What is your plan after grinding?

 

[newgarageguy]

It's a block base that is raised just slightly above the floor (walls). I think my plan is to do an epoxy floor.....

Not trying to be a jerk here, but don't you think it would be a good idea to know exactly what you want to do before grinding the floor?

Not really I mean it needed done and not like it's going to be a long time before applying an epoxy basically I know I'm doing an epoxy not sure which vendor to go with yet

I wasn't trying to be insulting, it's just that if you aren't sure what you want for a floor covering you may end up deciding to go with a plastic floor tile in which case the grinding wouldn't have been necessary. But since you KNOW that you want epoxy, then grinding is a good thing.

I don't think anyone doubts that a 7 inch angle hand grinder with a diamond wheel will grind a concrete floor. The only issue a lot of us foresee is the amount of time it will take and how hard on your knees and back it will be. It would be like painting a large house with a 1 inch paint brush. You can do it, but why would you want to?

My advice is, rent the right tool to grind the floor. You will be done in a lot less time and your knees and back will thank you.

Very sound advice. Mike

Why epoxy? Porcelin tile would be much better and cheaper.

Before you commit to epoxy, at least read up the porcelain tile threads and get some pricing for materials and labor. I would not even consider an epoxy floor coating as I have never, ever, seen one that has not lifted, discolored, bubbled, etc., after a couple years of use with daily drivers rolling in with hot tires. For me, the only solution is porcelain tile. Do it once, do it right and never have to revisit again.

Ok apparently you guys missed the fact I rented a grinder and did the majority of the floor, I was asking for the portions along the edge and the low spots that I couldn't get with the grinder....

 

[newgarageguy]

I mean come on guys I even posted a pic of the edco grinder

I used a 4 1/2" Dewalt Grinder on my Porter Cable. Just make sure you keep it moving as it works fast on concrete even with light pressure. I bought a dust shield but was a waste of money as it went everywhere.
