Re: Removing Oil Spots From Concrete.


Fred...I bought a can of rustoleum cold galvy and for some reason decided not to use it after shining them up on the bench grinder/wire wheel to descale some rust...probably should of I know.

Busy at work means not much time on the garage...I did however get some shelves up and walls and ceiling painted...17 gals to date. The masonry CMU's sucked up most as expected and required 3 coats to close up the surface and get a true hue.

Today I removed cover paper from the floor, jockied chit up on the shelves and was able to grind out my rear floor repairs I did awhile back...and let me tell you that stuff is truly 9000psi at this stage, a considerable difference in grinding the following day I will say.

Another thing I noticed is what appears to be the creep of small amounts of oil still coming up to the surface, not everywhere, mainly were it was worse (center back section) Think i'll wash again with TSP and hit it with the pressure washer before final etch. I want to still drag a chain over the slab in search of hollows and if I find more I'll get them grouted solid before I do the epoxy.

Re: Removing Oil Spots From Concrete.


Little update - long, cold, busy winter and this floor got put on hold until the lazy owner decided to get off his arse and get it finished.

Armorseal 8100 2 cts./ Armorseal 1K 2cts. Decided on doing 100% broadcast of the chip which took about 20lbs of flake.

Looks much nicer in person...

Looks great!! I would have never thought that TSP would have removed the oil like that,, oh and the hot water.
