HOW TO COVER WATER STAINS ON A CEILING – If you’ve had a water leak from upstairs then this generally leaves a water stains on your ceilings. It is futile to simply paint the ceiling as a water stain will seep through the emulsion and then you’ll be right back to square one. In this guide we’ll show you how easy it is to cover any water stains on your ceilings with step-by-step instructions.
The first thing you need to do is locate where the water is leaking from. This could be a cracked pipe, or leaking tap fittings in your bathroom or the silicone sealant may need replacing around the bath or sink. Once you have located and fixed the problem it’s time to cover up the water stain.
Check the area on the water stain and around it. You may need to sand down any flaking paint.
Take a dry cloth and wipe down the area of the stain.
Lay down a dust sheet and cover any light fittings with masking tape.
You can buy a stains blocker and this comes in either a spray can or in a regular tin that’s applied using a paint brush. Whichever type you choose, read the manufacturer’s instructions for application. The spray can version is very quick to use and most dry within about 10 minutes. Ask the staff at your local DIY Store if in doubt.
Put on your safety goggles and face mask before applying.
If you have chosen to use a spray then shake the can as directed by the manufacturer. Hold the nozzle about 12″ from the ceiling and depress the nozzle cap. Work from side to side and then up and down, until the area of the stains is completely covered.
Once the stain blocker is dry you should not be able to see the stain any more. If you can still see the stain then apply a second coat once the first is completely dry. Follow the manufacturers guidelines on drying times, which can be found on the tin or can.
Now that you have covered the stain and it is no longer visible you can paint the ceiling with emulsion if required and the water stain will not seep through the emulsion paint.
