Prior to having a new roof put on,my skylight leaked a bit in one corner and has stained the acoustic ceiling in our modular home.Is there any solution for removing the stain other than replacing the whole section or painting the whole ceiling.If I paint just the stained area it will not match the rest of the ceiling.

 

Try a product like Kilz in spray form. It will prevent the telegraphing of the stain through paint. Once the Kilz is dry, you can paint it with a matching paint.

 

It is hard to get old ceiling paint to touch up. As suggested you must use a solvent based primer to coat and seal the stain to keep it from bleeding thru the new paint.

 

I had a stained ceiling in my kitchen for years and even though we went over it with kills etc... the stain kept coming through the paint. a freind suggested "problock" primer by sherwinn williams, and it worked great! its been over 10 years and no stain to be seen.

As Marksr indicated, there are two types of Kilz, latex and solvent based. The solvent based id really the best to keep stains from telegraphing through the newly paint. I'll have to check out that problock. Always need good primers, right?

 

SWP has several primers in their problock line, one of which is very similiar to oil base kilz.
