damp celings and hairline cracks

[channy00]

could anyone please help me, how do you treat damp on celings? there was a leak from up stairs and the downstairs room is showing signs of damp? what steraliser, barrier cream and fungaside do i need. and please could you explain step by step on what to do. also on the celing is hairline cracks...is there any point in filling these in with fine surface filler or should i just flood them with paint. thanks x

Assuming the leak is now fixed, and you just want to be rid of the stains, use an oil based primer on the ceiling before painting with emulsion.

If the room is actually cold and there is condensation forming, you need to increase the temperature or the ventilation, then the dampness should go and you can decorate as above.

I think the thin cracks will more or less get covered over with the paint.
