after my water tank leaked in the atic there is a water stain on the celling how can i paint over this?

Answer 1

Use a spray called "stainblocker". Shake the can well and spray over stained area from a distance of about 18 inches. Don't apply glue as it will then seal the stain in as well as not allowing the plaster to breathe./

Answer 2

Firstly... I have listened to the advice given here... but they all have forgotten one very important thing... You will have too treeat the whole ceiling...

1... water causes damp... the spores will move if you already have a stain... it is there! The water will not have only made this area wet... it WILL have soaked into the plaster... causing it to weaken...

2... you will need to inspect from above the whole area, and treat with browning, or a silca bond sealant, for plaster (B&Q around a tenner a tub) you may have to remove and reboard the area... it is better to do the job proper, saving expense later! 3ft by 6ft board is 7 quid.

If you do not need to do this, follow my previous instuction!
Use the bond and allow 7 days for the sealant to take! Then paint as normal with Johnsons ceiling paint, as it already has anti mould additves! you will need to paint the whole ceiling as you don't want a patchwork job done!

I won't lie it's a messy task! remove your things from the room! it'll take about 4 hours to do the initial job... leave for a week and then paint!

Don't be silly and do half a job or your ceiling may give in a few months or a couple of years!

Good Luck! A plasterer should do it for around 100 quid! and that is a proper job... better than 500 for a new ceiling!

Answer 3

Hello there!!
There is only one way to remove the water stain from your ceiling and that is to put 2 or 3 coats of water proof primer on the area first.
If you just try to paint it with the original paint, it will always moisten the area and discolor it like the stain. With a water proof primer, you are sealing in the damaged area which then allows the paint to stay on top of the primer and not be discolored.
Also remember, going cheap on a primer will cause you more headaches then solutions. Start with a good primer and you will be fine!
I hope this helps

Answer 4

Make sure it is dry - clean off anything on the surface that might come off (eg light mould or water residue) then paint over the stain with a special stain covering paint - every diy store will have some. It is normally white so you might get away with it on a white ceiling - otherwise repaint afterwards.

Hope this helps

Answer 5

Is the ceiling acoustic? If so,has it ever been painted before?(most sprayed-on acoustic ceilings haven't) If it hasen't,get a small spray bottle with a adjustable nozzle.(16 oz. indoor plant mist bottle with trigger pump) Fill it with household bleach,protect any furniture below ceiling with plastic drop cloth,adjust nozzle to a fine mist,get close to the ceiling(approx.3 to 6 inches), keep your body especially your face away from the spray nozzle.Be careful there is no one below the mist as some might fall to the floor. be careful not to breathe the mist as it is chlorine.(sodium hypochlorite 6%) Spray your stain,watch it dissapear.Amazing isn't it? Some stains are tougher to eliminate than others, if stain does not completely dissapear try swimming pool chlorine instead of household bleach.(twice as strong,sodium hypochlorite 12%)I can't emphasize enough to be careful not to breathe the mist as it can float your direction as it slowly drops to the floor. if the air gets too unbreathable, get out!,let the air settle for a few minutes,and return with precaution. I have done this dozens of times with no problems. Just use common sense.

Answer 6

If you paint the edge of the stain first, the brown line it leaves, then leave that to dry. Once its dry then paint the rest of the ceiling. Totally works as I did it on my ceiling when I had water damage marks.

Answer 7

I'm a professional painter 30 years you can use any kind of spray can paint on the stain it doesn't have to be stain sealer then apply two coats of your ceiling color paint that's it easy huh ?

Answer 8

Seal the stain with an oil based paint - gloss or eggshell, then emulsion as usual

Answer 9

paint over it with PVA glue, leave it to dry over night. Then just paint over as normal. This is also a good way to deal with damp as it seals the plaster and will not allow moisture to seep through.

Answer 10

Only a few got it right, the answer is STAIN_BLOCK obtainable from paint shops. It's based on shellac in an alcohol base, and it definately blocks anything.
