Water damage on bathroom ceiling

Question

I am about to patch up this water damage on a low bathroom ceiling. What can i paint/seal the entire ceiling with to minimize future water damage? the ceiling is very low, and the shower moisture is what accumulates on it. thanks!

Charlene · Answer

I would apply at least 2 coats of Kilz, which is a mildew preventative primer.  Kill is excellent in moisture areas like kitchens and bathrooms.

She7831955 · Answer

First, as a retired drywall contractor... you need to peel off ALL the loose bubbled paint... then sand the edges of the old paint that is not loose (to cut the edges)... Then paint with Kilz one heavy coat should do it... then put 2 coats of the regular paint that you want to use. It is best to paint the entire ceiling, as you will see the patch, if you don't.

Hello Tova. It looks like the moisture has only affected the top layer of what is covering your ceiling. Do you have a vent fan or window in your bathroom? You'll need to wait until everything is completely dry and then scrap everything loose off. You'll need to sand, apply a  good sealer and then repaint. Look for paints that are made for high moisture and humid areas. I see you're in Israel, so check out Denber paints. They sell water repellent paints and  wet surface protection sealers. Good Luck! :)

Zinzer works well too and can be found at your local Home Depot.

Maine paint!!

Michael J Balsamo · Answer

If you have this problem it means there is NOT ENOUGH VENTILATION in the bathroom. No matter what you paint / repair with, it will be temporary unless you add an exhaust fan. Then I would apply any Kilz or similar product or even better, go to your local major hardware store where you can buy wallboard especially designed for bathrooms (often called greenboard). I would just place it OVER the existing ceiling, screw or nail in, finish the edges, paint and you're done

Shirley Kalinosky · Answer

All these seemed helpful and I agree with them all.  Only thing to add is, get the paint especially made for wet areas and def either open a window, or get an exhaust fan.

•This type of 'thing' happens often with cement & paint;& not to forget climate inside & outs.. The easiest & most attractive,& versitile way is firstly the area is lightly sanded, one light spray colour paint touchup to cover cement. Then from most craft shops/ or novelity gift shops, purchace sheets of foam felt of either a colour to make the area pop, or stay neutral, but the sheets you design  with ones own pattern, so it can be added to the roof using non toxic glues( thus simple to remove if needing to),& designing ones own roof pattern makes for a beautiful look.( Note before placing up, a light spray of clear matt/or gloss paint over your cut outs(back & front), depending on your personal style, will allow for longer lasting with absorbtion still being able to happen. This is good as it to quickly dries & thus it doesn't allow for moulded areas.) If one can't design their own then packs of pre-cut patterns, often used for coffee tables as different coaster holders/or vase on glass decor, can be obtained. *For extra safety if an owner is picky & doesn't understand that non toxic childs glues can come off neatly, then there are label tabs, that are a bit expensive, though will hold anthing just about to anything, then when removing only requires a pulling down  motion thus leaving a clean surface totally: I have done this method in three batrooms & always the owners want to keep, thus they will pay you..If choosing a colour keep within muted shades, as it allows depth with light making the area look bigger yet again.. Only wishing the best to all for keeping a smile while 
crafting.. M.Rã

By looking at the picture, it appears that the surface was not properly prepared when it was originally painted. If it was a glossy surface underneath, it should have been scuffed up to remove the gloss. Then it should have been primed with something like Kilz before the final color was applied. Should use two cars. There is also an additive that can reduce mold/mildew problems. Ask your paint store

MargaretHoulihan · Answer

Coats not cars... Stupid auto correct!

Lisa · Answer

We tiled our ceiling in the bathroom using large 12x24' white tiles. We had the same problem.  The bath fan we had was not enough.

HausDoctor · Answer

Make certain you properly size your bathroom exhaust fan and that is discharges outside the home not inside the attic. Then remove all loose paint and paint with Kilz or BullsEye which makes a paint specifically for this purpose.

Linda Santo · Answer

I used Zinzer Perma-White on my bathroom ceiling.  My roof leaked and the drywall actually buckled and dropped but the paint stayed perfect!  Only thing I've used in 2 bathrooms-old house-no exhaust fans.  Swear by it.    And hello, Margaret from a few miles down the road!

Suellen Hintz · Answer

Seems that you need to install an exhaust fan or a newer/more effective one than you have.  No sense in repairing the moisture damage until this is done.

Mizzhoneysuckle · Answer

Never use a flat based paint in a bathroom or kitchen.  Use Semi-gloss or gloss.  That will keep moisture out.  I used a Semi-gloss Ultra Pure White by Behr, and no problems at all.

Sophia,M.,McConnery · Answer

Semi gloss exterior paint is the best for bathrooms.It is meant to withstand all weather conditions.Most of them have a warranty for 8 + years as well.

Jean · Answer

I surely don't have the answer, and cannot find one here, BUT would love to see one (or more) solutions, because I have the same situation. Thanks for sharing.   Je

Lori Siska · Answer

I have the same problem.  The house we bought is over 100yrs and the glass block window the developer installed doesn't open.  The fan installed is poor quality and doesn't do a thing in the winter when we need it most for moisture control, so we know we need to get a better one - any suggestions would be helpful (but it's gotta have a light).

JEWEL C · Answer

I have a water damaged ceiling but from AC overflow. I am putting  Faux tin pressed panels on it. You just glue them up over the damaged areas. 
they are plastic and light weight so @ 80 years old I can handle them easily.

Maggie Hecht · Answer

When I was repainting some rooms in my Parent's old house, one of the bedroom ceilings was really stained from a leaky roof that had been fixed.  Nothing worked to cover the stains until I bought a product called Kilz.  it's a wonderful paint that  does the trick if you decide to use oaint

Genny N · Answer

In order to keep bacteria from spreading, any water damaged sheet rock, if re-usable has to be treated/painted with Kilz, used to protect the ceiling from continuing mold etc, therefore preserving the ceiling.  Black mold must be treated in order to keep it from spreading.  Black mold is highly allergic

Charlette Vroman-Smith · Answer

we used cheap hair spray before painting. It contains lacquer spray about 3 coats. let dry (drys very fast) then paint. It has lasted over10 years . Is cheaper then KILLS, easier and smells much better

Updiane · Answer

Besides agreeing with Maggie's post about using Kilz-many decades ago a carpenter gave me a tip to brush over the stained area with shellac before painting. It worked well for me.

Pamela Robertson Pullmann · Answer

There is a product called Kilz that is supposed to kill mold and bacteria in these kinds of situations. I know Home Depot carries it. Then you probably should put a waterproof sealer on top. 
Good luck.

Linda Johnson · Answer

We used Zinzer oil based primer on ours.  It's like KIilz.

J747725427 · Answer

best stuff to use is Zinsser mold killing primer. you can roll right over mold its awesome !! roll dont brush 2 coats then paint. it drys in less than hour!!

Helen · Answer

Drastic, but best.   Using a saw, cut around  the affected area. Replace that spot only with new dry wall  After replacing you will need to 'tape' the edges before adding joint compound and smoothing.  To finish off the job lightly sand joint compound to make ir  smooth as the other space.  Once done you will have to paint the whole area,

Wilson Stevens · Answer

I have a home in Michigan that was on the historic registry that had to have approval for any repairs. We had extensive water damage to the ceilings in several rooms. I used 'Kilz' and it worked in every case. I have had to use it several times since, and have always have great success.

D roach · Answer

the easiest way is to add ventilation. ie Open the window after taking a shower and never close the bathroom door. It allows the room to circulate air and dry out. if you close the  moisture in the room it has to settle somewhere.

Janet · Answer

No one has mentioned a ventilation fan, or am i  too linear in my thinking (accused!)?
