Destroyed floor......Maybe not!! Diamabrush
Hello all. Been a long time lurker. Really some great info on here from all of you.
A little background: 6 years ago I bought a 20,000 SF warehouse that was built in the 40's, in the heart of Chicago. I use it for my race shop and fabrication space. I am a contractor, so I'm not an idiot when it comes to doing any type of construction.
Now my floors are all concrete. I had a company come in when we bought the place and they used hot water and a industrial pressure washer to "clean" the floors. Well they have always been ****. Full of oil, caked on oil and dirt. I mean thick in spots 1/2". I had given up over the years trying to get them clean. I got a quote to just tear them out and pour new concrete. Now the price was far as one of my subs was cutting me a break, I still didn't want to pay that much.
Soooo, I bought a Diamabrush 7" wheel from my big grinder. Cost me just under $170.00.
Wow. Wow.Wow. It works. Really well. I did my back loading dock, which has the least beat up floor. It had big spots of built up oil and dirt that came right off.
It took me about 1.5 hours to do about 1,000sf. When I started with the new blades, they measured .377 or so. When I finished this section of the floor They where wore down to 0259. So not bad.
I had spots where the concrete transitioned to patches for my dock plate what where uneven. Not a problem, ground them level!
On this type of concrete it works great. I used an old Milwaukee grinder. It spins @ 5,000 rpm. Its heavy, @ least 10-15 lbs. I put no real weight on the tool, just the weight of the tool seemed to work just great. I used they dust shield which I had to make an adapter to work with my grinder. The shield works really well. There was almost no dust.
My only issue is the grinding marks. The blades where 25 grit. I don't know if I use a different grit?? But they are not bad. I might go over it one more time just to get out some more of the imperfections.
Then I might seal it with Legacy sealer?? Not real sure what to do as I have never done anything like this before.
I have the rest of my shop floor that is in real bad shape that I'm working on. The guys @ Legacy have been a wealth of info and help.
Sorry its so long, hope this helps someone out in the future.
