    We had some damp come in the ceiling together with some black sticky stuff.

    It may have been caused because of a damaged tile on the roof.

    Can anyone tell me how to remove the black sticky stuff please? It may be tar?

    Thanks

    Scrape it off using a ....scraper :) then using white spirit on a small sponge, dab it on the patch and scrape off the excess left behind. Repeat till you're happy with the result.

    Latex gloves and goggles are a must. Or it's dermatitis and blurred vision for some time. :(

    Having said that, I've used T-cut to remove tar from car paint, and sometimes WD-40 too.

    If its difficult to shift give it a coat of knotting solution, this will seal it. It does bleed through most things but not Shellac.

    Like RobbieUk says, you'll need to block it using a sealer. Scraper wise, just a standard wallpaper/paint scrapper. If you not sure, then I'd recommend taking a picture of the condition of the area, and taking it to your diy shop for a suggestion. Just make sure it's sharp.

    Chemical reaction with the water and paint?

    Crystallisation?

    A picture might help... :)

    The white stuff is efflorescence, just scrape it off, do not wash it off.
