Oil based paint on slabs

    Just wondering If anyone can help me out. I was finishing up painting my door with red oil based paint and cleaning up soem paint I spilled. It was late and dark and I was unaware there was paint on my shoes walking the paint in to Indian sandstone slabs out the back. I didn't notice it until the next morning until it was dried. The slabs has obsorbed the paint making it difficult to remove. I've tried power washing it, scrubbing it with white spirits and santrax brick and concrete cleaner but non has really worked. Any help is much appreciated

    Paint all the slabs the same colour. #simplefix

    You are going to have to mechanically remove it i reckon.
    Sandstone is very porous unless you have treated it and based on your results you haven't.
    Are the slabs cemented or sanded in place? Are they regular shapes?

    Wire brush.

    Thanks for your reply. They are cemented in place.

    I've tried wire brush with white spirits but unfortunately doesn't work. The paint has soaked in to the slabs

    Hammer and chisel. Progressing to pneumatic tools.

    How big is the paint mark
    What kind of slab

    Post up a pic

    I'd try Nitromors paint remover as the paint is already dry. Dab it on and off. Try it first on an unseen part of the tiles/slabs just in case it causes discolouration.

    Chemicals are the way to go.
    You need some of the serious stuff pro firms use, not the DIYer stuff. And it will probably require repeat goes.


  • Registered Users, Registered Users 2 Posts: 268 ✭✭SnazzyPig


    Remove the slabs and replace them upside down.

    Acetone spray(nail polish remover)might soften it.
    Or pour some petrol on it and set it alight.

    Close the patio doors first though.

    But the insurance pay out will buy him a new house with new slabs!

    There really is no way to get rid of oil based paints that have penetrated porous tiles/slabs. The paint has gone right through it. You could try sanding it but I doubt it would work. Being red it should fade over the years as the uv rays break it down.

    I wonder is there a fast track way to 'bleach' it with UV? Like an intense lamp?
    Then again I have no idea what I'm on about, but it makes sense in my head.

    He should have used a lamp instead of painting in the dark

    If it has soaked in I'd guess any solvent won't do much, it might soak across a larger area and dilute the colour a bit, but you won't be able to remove it any more than you can take the piss out of a swimming pool. Have you tried consulting a druid?

    Could you not just flip the tile over? Presuming both sides have the same finish of course.

    I'd say the other side could be destroyed cement.

    Acetone.

    I'm going to try a small bit of acetone and see if it works. Thanks

    Pretty much what mad muffin has said.

    You could try using a hot pressure washer, it will come up a bit but may not be perfect.

    What you could do is seal the rest of the slabs to make it blend in a bit, don’t seal the painted slab, let it weather for the summer.

    The good news with sandstone is that paint will fade over time, if it was me I’d leave it until next year and then worry about it.

    No, it is even stronger than acetone. A strong acid. Seen it used very effectively on a project I was on.

    Acetone will evaporate before having any effect I would imagine.


  • Registered Users, Registered Users 2 Posts: 3,689 ✭✭✭Signore Fancy Pants


    Have you tried turning it off and back on again?

    Sandstone, because of it's nature will clean itself over time. But depends on how deep the stain is.
    I would say maybe a few mm's but not much more.

    Soak some rags or tissues in paint stripper and leave it on overnight,might draw out the paint.

    Build a sacrificial altar just above the stained slabs, nobody would question the red stains then.

    He could try HF and get rid of the whole slab.

    Perhaps DMSO with 6% sulphuric acid to remove the paint.

    Get a Sander machine and try and sand a bit off and see how that goes. I wouldn't try add any more liquid based solution to it. All that's going to do is make your tiles look like Mikhail Gorbachev's noggin x 100
