I am about to buy a house which has a garage with major oil stains all
over the garage floor. The stains appear to be old ... maybe put down
over a couple year time frame.
I am thinking about cleaning the floor with muriatic acid. Then I
intend to paint the floor with a couple coats of patio concrete deck
Does anyone have experience with this. Will the paint hold for a least
a couple years? Are the stains likely to show through over a couple
Thanks for your input,
I would use an epoxy paint and clean prep as the manufacturer recomends.
One manufacturer has this to say..
"Remove any oil or grease spots on your floor. Use a scrub brush and a
cleaner/degreaser (such as Simple Greenฎ) or use a solvent such as mineral
spirits. Scrub the spot thoroughly and wipe up excess cleaner with rags or
paper towels to keep contaminants from spreading. Rinse thoroughly with
fresh water. Repeat as necessary to completely clean."
Muriatic acid is not a degreaser its basicly diluted hydrocloric acid.
Put some mineral spirits over the stains and scrub with a stiff bristle
brush. Then cover the mineral spirits with cat litter. Allow the cat litter
to absorb the mineral spirits then sweep. Repeat as necessary and the stains
will eventually disappear.

In addition use flat soled shoes, NO TREAD... Helps grin in the kitty
A friend had a spot in his driveway that was years old now it is clean and
Plan on several applications, and let sit for several days.
I suggest choosing a good two part epoxy garage floor paint. Note: If
it is not made for garages, it likely is not made to handle hot tyres and
will not hold up, although it might work fine in a basement.
Follow the instructions on the can 120% percent. Especially the part
about preparation. It will tell you have to clean up that oil. The acid
will help provide the proper surface, but it is not an oil solvent.
Sounds like a recipe for disaster. Muriatic is not a cure-all or
clean-all. It won't eat acid, but eats concrete. I would try some
kitty litter to suck up oil, a couple of applications. Have never
tried, but would not entertain thoughts of painting oily concrete.
Whatever you do, do not use paint on the garage floor. When your tires are
hot, it will melt the paint, lift it up and leave an awful mess. Even epoxy
is iffy, depending on preparation and the presence of efflorescence.
