epoxy over oil

[bannanabread04]

I know that tis has probably been posted time and time again. but im sorry here it is again. ive scrubbed and scrubbed and scrubbed. ive used rocksolid heavy duty degreaser from rustolum and ive even used some chemicals from work that obliterate fats and oils. but I just cant seem to get rid of this oil. my main question is im getting ready to say screw it and paint over it but im worried about it just not seating at all and pulling up like stick on linoleum without any glue on it. will it stick enough that I really wont have to worry about it? is the epoxy hard enough to "bridge" the gap of non-adhesion? I really don't like the idea of someone coming in and grinding it. i don't like to pay people DIY! lol

thanks in advance for the help!

If you dump water on the stain does it soak into the concrete? If so, I'd think you're ok.

 

[bannanabread04]

It's soaks in but slowly.

You can get small diamond grinding discs from HD/Lowes that's made for masonry, they're $30-40 iirc. I'm not sure if it'll match the finish of the rest of it post grind though...and you might create a low spot.

Put some water on the oil area and some water on a dry patch and compare the time to soak in. If it's close then you should be alright.

Might try some bleach on those skid marks

Pour some lacquer thinner on them and then cover with baby powder. The thinner pulls the oil up and the powder absorbs it. You may have to apply two or three times.

 

[bannanabread04]

Didn't have any lacquer thinner so I just put some baby powder down to see if that will get some up.

This guy tried a few things and looks like carburetor cleaner worked pretty well:

It's pretty harsh stuff so it's not surprising that it did work.

 

[bannanabread04]

I know I seen that too but I was worried what kind of chemicals it left behind and if it would do anything to the epoxy

My experience with this problem is a lack of patience shown.
We have come to expect “instant gratification” and we do not take into balance that many of these problems took years to occur.

My solution to soaked in oil is powdered Tide sprinkled on deeply and moistened to a paste.
And then just allowed to sit under a bath towel or poly sheet.
Do nothing but keep it damp.
The soap will soak in and wick up.
But not overnight.
It can take over a week.

 

[bannanabread04]

Now that I can try it's supposed to rain all week any way I'll go buy some tide today...do you just keep the towel wet then or do you just lift it up and water the tide? I'm in no rush to paint the floor I just want it done right.

This is what I used, http://www.pour-n-restore.com/ It worked fairly well on my oil spots. I used it and a combination of Simply Green and lots of scrubbing with a really stiff brush.

As far as I know you have to do it on the computer I don't think you can make one one tapatalk.... Welcome anyway

Go rent one of these for a day (with a vac) and prep the floor the best way. Adhesion to oil is going to be an issue without removing it.

I hate to tell you this but grinding doesn't do anything for oil stains. You have to get them up as good as you can, before you grind the floor.

 

[jaye944]

mine was like yours, its is now a lot better; havent updated my thread, but check the links in the sig

you may not need to grind, after I de-oiled as much as I could the acid etch did a great job -- (havent uploaded the pics yet)

Yea I don't think I'll grind I've etched it already and the oil came back again. So I'll try most of these methods and re etch. I'll let you guys know what I come up with.

 

[jaye944]

with me I had a really bad bit, and it was fine;

check to see if the water BEADS on the surface; the oil can go in really deep.
ALSO when you grind you re-ope the pores and the oil goes deeper. apparently !

Try Pour & Restore, I couldnt as its not readily available in Canada

Guys I use this product for all of my oil spills. It seems to do a fantastic job and it has worked for me every time. It's made for machine shops and other oil rich areas, Kem Tech Surfact 1281. It's something like $75 bucks for a 5G of it, so I am sure much less for a single gallon. Just throwing another option out for ya. If anything, call KemTech and see what they recommend.

This stuff looks promising... Where can I buy it? And that oil looks like it was just put on there and not quite soaked in yet though

There was another thread here where soemone suggested using a mixuture of 50/50 water and dawn dishwashing detergent. I tried it and it does work, but it takes a few days per spot. Put some clean paper towels down over the stain maybe two or three layers. Thouroughly wet the towels with the diltuted dawn. use a piece of flat metal or painted plywood or melamine over the spot, completerly covering it, so it can't evaporate too quickly. Wait a few days, and you will find the oil has moved from the concrete into the paper towels. If you wipe the exposed wet spot with a clean paper towel, it wont stain if the oil is gone. if not gone, redo the process. After you're sure the oil is gone, with a brush scrub the spot with hot water and rinse it to remove the detergent from the concrete.

Almost everything people suggested DIDNT work for me, I think try what you see and some works, depending on the stain, how deep and what it is.

See my link for a list of stuff which defo wont work

You would buy it from them, they ship it from Wisconsin.
