Best way to remove a water stain on ceiling?

"You can use a stain blocker in paint or spray versions or replace the board re skim and paint."

"Hi, use a oil base stainblock to cover the stain and then repaint ceiling"

"Make sure stain has dried then apply zinsser primer or zinnser stain block. Use oil based under coat if you haven’t got any zinsser and apply twice. Touch up with emulsion when dry.
Might not blend in perfectly."

"Hi Greg the best way to remove water stains is to buy a can of spray stain blocker which you can usually paint over in ten minutes alternatively you can coat the stained area in a oil based paint i.e undercoat but you will need to leave approximately 16 hours before painting over

Hope this helped with your question."

"You can buy a stain block at most DIY place in areosal and drys withing 20 minutes then can be painted over but make sure room is vented it can be brought where you can paint on but that is more expensive but depends on how big the stain is. This dries white."

"Buy and use a stain block spray from any decent DIY store or your local Screwfix.
The spray is easy to use, dries in 10 minutes and depending on which brand you use, will dry flat white like emulsion. It may be that you need to touch in the ceiling with the white you used previously so that it colour matches.
Zinsser is one of the best branded, market leading stain blocks available.
There will be a strong after smell from any of the stain blocks so ensure that the area is well ventilated and this will subside quickly

Hope this helps.

"The best idea is to cut that side of ceiling where is the leak and to change with a new piece of plaster board, depend how big the area is"

"Unfortunately you will have to repaint the ceiling after sealing the stain with BIN. Give 2-3 coats and then you can repaint ceiling."

"Good evening, first use zinsser paint. Let it work for 1 h and apply colour over"

"You will need to put stain cover on it. This may still stand out a little but not as much as the stain."

"You need to use a blocker first. This comes as a paint and aerosol form. Once dry you can emulsion over."

"Use b.i.n by Zinsser, it’s a stain blocker that dries to a Matt white"

"Firstly as long as it has dried out use oil based gloss paint. Paint over the patch let it dry for 2 days then just paint over with a few coats of emulsion"

"Providing the surface is sound you can use 2 coats of zinsser BIN primer this will seal the water stain."
