   What are you using to prime the stains? I've had this happen to me before, and I first cleaned the stained area well (removing some of the stain in the process), then I primed with Bullseye 1-2-3. I would think that a good stain blocking primer should do the job.

   *I've had consistent success with Zinsser BIN or other pigmented shellacs sealing stains but the drywall or plaster has to be dry.

   Both Zinnser products (1-2-3,B.I.N) have given me good results over water stains but as others have memtioned, the plaster or drywall MUST be dry ....closing the room off and and running a dehuidifier for a few days may help .... you may be suprised at the the ammount of moisture you collect from a seemingly dry area. A heat gun or hair dryer will work to dry small areas but Be Careful not to overheat the area, especially if you have wood lathe behind the plaster. Good luck. jc

   Use Kilz aerosol. Very easy to feather in and to spray thin coats.

   This problem is not uncommon.

   After finishing the NC State Capitol they had this one little spot, about 1/2 foot around, that would just keep coming back. They had a real slow leak causing it.

   This spot was thirty feet off the ground so it was a real pain for them to have to fix it.

   What finally got the job done was about 5 or 6 coats of Kilz.......And a lot of time and money.

   *I've seen plaster walls that remained damp for 6 months! In this case I could go into the attic to remove the loose fill insulation to increase air flow. I was floored when the homeowner told me that the roof was repaired 6 months before! Water stain will bleed through spackel,latex, acrylic and most oil based paints. The only sure remidy ispigmented shellac, Kilz, Bin or similar product.But it must be dry, or it will flake off.

   I recently occurred water damage in my house from a leaking roof. I have water stains on drywall ceilings and walls as well as some original plaster ceilings and walls. No matter how many coats of paint I apply, the water stains still bleed through. How do you prepare the surface to properly cover and conceal these water stains? Are there any specific products or procedures?
