I've been tasked with painting the daughters bedroom. After the removal of posters blue tack has left an oily stain.


What do I need to do to paint over these to ensure the marks don't seep through the new emulsion?


Thanks

    Could try rubbing alcohol or another name is isopropyl alcohol excellent degreaser. I think nail vanish removal is same stuff. I always have some because of good for cleaning windows when highly diluted

    Nail varnish remover is Acetone. A completely different chemical from isopropyl alcohol (IPA). Both are pretty good solvents, and nail varnish remover is a lot easier to buy than IPA.

    I have used the special paint for hiding water stains as an undercoat.

    Just use some meths to clean the stains.

    Don't use 'white spirit' - aka petroleum spirits or turpentine substitute - it moves grease around rather than lifting it.

    I've been looking at how to prepare walls to paint and the advice seems to be to use sugar soap - £2.50 from wilkos

    https://www.wilko.com/en-uk/wilko-sugar-soap-ready-to-use-trigger-gun-500ml/p/0127762

    It's slightly acidic, so wear gloves.
    That sounds like a classic case of premature extrapolation.

    Like knightstyle I would use stain block paint on the stains before going over it all. It does what is says on the tin!

    I wouldn’t waste time and money on stain block paints unless you need to. I’d clean using something recommended above, then paint over each stain with the paint you intend to use, wait for it to dry and see if the stain shows through before painting the entire wall.

    I repainted a magnolia coloured wall in daughters student accommodation due to blu tac (worth an hours work rather than risk no return of deposit)

    I put some paint just on the blue tac stains first just to give them a quick, additional spot coat (similar to what has already been suggested with a specialist product) and after 30 minutes just did the whole wall as normal - my experience was it worked fine.

    Hope this helps
