Ceiling Painting after leak

choccymousse

Hi Folks ,

We recently had a leak from the bathroom which has ruined the kitchen ceiling leaving crop circle style brown patches all over ! Would anyone have any advice about painting over same - anything particular we should do prep wise before painting or any special paint to use ?

Thanks and any advice much appreciated !

You can get a stain block paint, I've used it in the past and its fine but a bit expensive. I've heard most oil based paints do the same job but heard that after I had used the stain block so never used anything else. Obviously use it when the ceiling has dried out properly.

I used Thompson's one coat damp seal on a similar problem and it came up great. It is expensive but you can get a small 250 ml tin.

Leave it to dry completely (4 hours or so) before painting. When you first paint over it, it shows through but when the paint dries it it looks fine.

You can also get aerosol cans of damp seal to spray on over water leak stains.Any good diy store will stock the aerosol cans.About 8 euro for an aerosol can.

I have used white undercoat paint in the past to mask such watermarks. Then repainted the ceiling.

White undercoat will do the job.
