How to remove black sticky stuff from a white emulsion ceiling.

JamesEB · 20 Sep 2015

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.

Thanks. I don't have any DIY shops or tradesmen here which I why I love to have this site.

There is also some white frothy stuff on this ceiling. What is this please?

Thanks for help.

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.
