this is my first post so i hope i do it right!
My question is how to paint over some stajns that keep coming through the paint.
there ws a leek in the roof and water came through , if i am to put a fresh coat of emulsion on how do I stop the stain comi9ng througfh?
also we have some old beams that have been painted over but whatever they were treated with shows through as a brown stain. what can I do to seal the beams and paint over . we'd like to use emulsion on the beams as it will be same as ceiling.
looking forward to hearing how to do it
