Ceiling Stains

[boo coo tracks]

Old house, owned by me for 3 years. 1 stain dinner plate size has been repainted 6 months ago. Now brown stain appears again. Roof does not leak insulation added 3 times over the years. Attic is well vented & appears to be dry. Any issues I have missed??

use Kilz on it. Then your ceiling paint.

This.

Any critters that might have a nest up there ?

Where is the stain..middle of the room/out near an outside wall...?

I had this with a popcorn ceiling.

I used Killz spray can on it and it took a couple of coats but the stain is now gone and the satin white of the Killz was a close enough match that I didn't have to paint the ceiling.. A few years later I did repaint and painted the ceiling too - then we threw out all of my wife's candles... Soot.

I was the carpenter, for a General Contractor, who had to do punchlist for a 550 condo construction project, lots of ceiling stains. We used a 50/50 mix of clorox and water in a pump spray bottle to kill the stain then when dry used kilz spray . Then usually had the ceiling repainted. Worked on flat and popcorn ceilings.

I'll agree with the Kilz too, I prefer the oil based primer.

is there a bathroom above it?

I was a painter for 20 years. Kilz is the best for it. If you are painting the whole ceiling just use an interior oil primer thinned down as it will be much cheaper than Kilz.

No just standard attic, bathroom is on other side of house.

Is there a place where snow or water might be leaking in? From a vent or something in the side of the house? Water from a leaky pipe can travel a long way before it finds a place to come through.

We use this for acoustic ceiling tiles in our stores, its not always a perfect match but it matches better than the stain and is designed to spray up. You need to practice so you can feather the edge and make it less noticeable. Just an option.
