I work in the monument (gravestones) industry and we occasionally need
to remove oil spots on granite/marble monuments, usually caused by careless lawn workers putting an oil can on a monument. While the following method may not be suitable for an entire floor, it works good for smaller spots. Make a poultice paste of common white plaster and laquer thinner (or white gas) and slather it on the stain with a trowel, leaving it approx 1/2" thick (thickness not critical). As it drys the plaster will draw out the oil. When dry, scrape/sweep it off. Be careful not to let the plaster get wet from water (if outside cover with plastic sheet) or it will harden and will have to be chipped off with a chisel. Like I said, this may not be practible for a large floor....but will do the trick for smaller stains from engine oil drips on a hanger floor. Deep stains may require more than one treatment. Usual disclaimer about being careful with fire/sparks near flammable substances, etc. Rich A. |

I'm not sure I'd like to try that...probably would end up setting the
whole township on fire with my luck Scott Stan Kap wrote: Scott, I watched a guy at an airport one time that took a 55 gal drum cut off both ends then set it over the spot on the floor where the oil was, he then poured some fuel on the stain inside the perimeter of the drum and set it on fire. It burned away the oil stain completely. Later he epoxied the entire hangar. It was a big hangar too, about 150 x 200 for King Airs and the Citations. Stan Kapushinski "Scott" wrote in message ... I'm looking to find some product that can remove oil stains from concrete so that paint will stick. My shop used to be used by a car mechanic and now that I build airplanes in it, I'd like to paint the floor a very light gray or off-white. I don't think that just using "Gunk" will remove it enough to get the paint to stick. Maybe some sort of epoxy-like sealer first?

I've had good luck with two unlikely products.
1. Cement. Straight out of the 94 pound bag. I use it as a sweeping compound. It sucks the oil right out of the concrete. I've never tried painting over it, though. 2. Liquid diswashing detergent. Not the kind you squirt in the sink, the kind you squirt in the dishwasher. It works especially well outdoors where the sun can later bleach it. "Scott" wrote in message ...

I used Pour 'n Restore to get the oil stains out of my concrete floor so I could paint it. Worked great, I'm a believer. After I got the oil stains up, then I did the acid etch. IIRC, I used the Sherwin Williams garage floor treatment, and after they sold it to me and I botched the application, they said it should only be applied by professionals. Oh, well. Ed Wischmeyer |

Ed,
Didn't we talk about my experience in painting my garage floor before you did yours? What do you think got "botched" when you applied it. I believe I used the same product and got awesome results.

said: Didn't we talk about my experience in painting my garage floor before you did yours? What do you think got "botched" when you applied it. I have no idea what I did right or wrong. Other folks in the neighborhood have used the same product, some got great results, some got poor results. It might be the concrete, stains that didn't come out completely, or phase of the moon. Totally flat learning curve on this one... Ed |
