Getting ready to do my OTHER garage floor

I don't think that would be bad but, just don't let it "dig down". I probably would only do the tough spots with that machine and then sand the rest of it, or it might come out uneven..
just fyi-- I have never used that machine, but I am sure you have the same thoughts as I do with it.
Good Luck!

In my experience with staining floors, that's too aggressive to start out with. And trying to get 1000 sq feet to look uniform with a machine that uses 2 9" discs is going to be tough. I'd first rent their floor buffer with about 3-4 black pads, add water and the texture and paint scrubs right up. If yours is really 1/2" thick, I'd prolly chisel most of it up by hand otherwise, just keep the buffer pad on it longer and it'll eventually come up, just keep the hose going at a low spray, turn on some music and take your time. If you don't like the results of the buffer, then get more aggressive if you like.

BTW, my floor had some hard paint and texture on it as well and this is what I found to work best. Turns out the builder also painted some shelves in the middle of our floor and the buffer got it up with a little patience.

Thanks, it was 1/2" thick in spots but overall averages probably under than 1/16". So maybe a floor sander with some serious low grit wet discs will do the trick.

My painters told me the texture will loosen up by just getting it wet. Will see what the rental places have in the order of a large disc sander

A pressure washer will do miracles with bedding material and paint...and it will move a helluva lot quicker than that montrosity of a machine.

I know the Owner of a company called Final Touches and she specializes in flooring. Grinding and what not. Was Contracted with Lowe's and did those floors during the building process. She knows her stuff if you need to ask questions about grinding/sanding the floor. I actually called her the other day myself to ask about prepping my floor for the epoxy type paint stuff I'd like to do.

It does look pretty menacing doesnt it? Wonder how fast those discs spin?

Fast enough to fling your old ass all over that 1000sq ft garage, especially when it "grabs" the concrete...LOL!

I missed this post earlier - do you have her contact info?

you have the correct machine..........but i have the diamond inserts you need to cut up mastic and any other kind of crap that might be on the floor. If they will lease you the diamond inserts go for it, cause it takes about $2K to fill that single machine with diamond inserts. a shot blaster will not take up mastic.

cool - this is just some paint and texture that was smeared and tracked around in one corner near the stairs. They actually did the same business up in the loft as well but its wood and I was probably going to cover with berber or some other studly carpet.

I have a 2500 PSI pressure washer but for removing minor suface paint and texture, and generally roughing up the surface maybe a 17" rotary disc style floor sander would be more suited for the task?

The grinder looks enticing, but how do you control the level of it? Sure looks like it would be one loud MF as well. How fast do those discs spin?

it's a very low rpm machine and the noise with diamaserts is really not to bad, and it controls it's own level, the wheels have enough surface area and float so as to not dig in, and trust me, it doesn't cut near as fast as i'd like it too sometimes.

If you don't have much of the tuff stuff to get up you can get one of those diamond wheels that's 7" diameter on a buffer and do it by hand..........this is what we edge with, but damn, it makes a mess and where a mask.

Cool, now all I need is some help to do all this. Sanding, cleaning and prepping 1000 sq ft will be a full day of fun for one guy.

When we had our restaurant floors diamond grinded to take the glue up from carpet it took the guy days.

Lucky for me I dont have any mastik or carpet glue to deal with, only the paint smears and some wall texture near the base. I have scraped most all of it already. There is some unkown crap that looks like some sort of resin that was spilled. It's covers 20-30 sq ft. Hopefully the floor sander will make quick work of it.

My idea is to sand and remove surface contaminants, sweep, spot clean and pressure wash, rinse, then mild acid etch, and final rinse.

Floor prep

After I moved all my 49 year collectiuon of junk and stuffed it into our other garage I found a couple of oil spots that concern me. I swept them clean and put Milsorb down on them. I hope to roll paint on Saturday, what is the best way to super prep those areas?

I thought I read where someone had used a propane torch to burn off what residual oil had soaked in beneath the surface. Is that a standard practice or? Any special treatment for such areas other than scrubbing with soap and a heavy wire brush?

i'm gonna give you the million dollar secret to cleaning oil from concrete for coatings...................rosebud propane torch, and it will crystalize and make most of it come up when you pressure wash it

Looks good so far. I want to do mine so bad on my next vacation, but I'm wary about moving all my shit in to the driveway and having to leave it there for several days. My garage is behind the house, but still.
