It looks to me like you didn't wait for the plaster to completely dry before you painted it. Then you must primer over fresh plaster before you put the finish color on.

but its only on this area and noy=t anywhere else.i think we gave time for it to dry.can it be because of fungus or something!!how to fix it

Do you have rising damp, leaking pipes or a leaking roof? Did you paint in the rainy season? Resist the urge to fill every space up.

I learned from the professional painters that they "sponge down" or wash walls before painting especially if construction dust has recently been in the air. If dust or dirt has settled on freshly primed walls and then you paint without cleaning walls then you are painting dirt that will later fleck off.

There are other things that could be happening too, Here the pros I know swear by "kilz" as a primer and barrier against mold so, without question they all insist upon a PROVEN primer barrier on the wall to get a good paint finish. The commercial painters are unwavering on this issue as their liability is great, So, you must research your primer and use a proven product as well as a quality paint. Go to Benjamin Moore website to see and explore other "paint trouble shooting problems and advice". Good luck!

wht shd i do to fix it..there are no leaking pipes or anything

the primer and paint i used was asian paints which is best in india..its funfus resistant and mold resist but i dnt know wht is it..it happened in sum other places of home too where i scrubed it and got it painted again...there a groove in wall but looks better than these bubbles..

what shd i do to prevent it and fix dis other than my idea??

thnx dear..sure will do dat

Is your wall a masonry wall? If so, What I see looks like efflorescence. It is caused by moisture migrating from the outside to the inside, and with it it captures and brings with all sorts of minerals and salts.
scraping and priming and patching will temporarily stop your problem but it will not be permanent. The issue lies on the other side of the wall or possibly above that spot .

I agree with R. Rodgers. If you found fur like material under the paint you have some sort or mold or fungus problem caused by moisture. There are products available that act as moisture barriers but I have no experience with them.

I was told that this usually happens when a paint is applied on top of another finish and no primer was used . Example oil and latex wont adhere .
Also look for leaks .

Looks like latex over oil or not completely dry substrate before paint job.

There is no problem using latex over oil. In fact, it is the only thing that can be used to solve problems caused by oil based finishes, such as mold and mildew.
Latex paint has adhesion characteristics that are far superior to oil / alkyd paints in almost all situations.

"sum fur like material inside."
The "fur" could be a mold, or it could be crystals of plaster from trapped moisture. I've seen fine needle-like crystals of gypsum appear near leak areas and push out the paint. The plaster dissolves and recrystallizes.

"we put 4 layers of white puttey and cement first "

If you are painting over plaster or stucco you have to let it completely dry and cure for 60-90 days before you paint. 4 layers of paint probably trapped moisture and it bubbled.

Scrape out the bubbled area, patch it with plaster or spackle, let it thoroughly dry and then prime and paint.

What are the walls made of? Does the rain hit them? I have a mud brick house in the USA (we call it "adobe", but it's just sun-dried mud) and have to be careful to not use interior or exterior paints that will trap moisture coming through the walls. My house has to "breathe" or first the paint will pell and then it will turn back to mud and collapse.

The old-fashioned mineral pigments, lime-washes and clay washes work best on my house.

===============
I like the room style - it's very modern yet unmistakeably Indian.

You don't need anything in front of the window. It's an attractive window.

That room is elegant and nicely decorated! I would let the drapes fall naturally. Try taking the tie backs off the drapes and letting them hang straight down.

I think what tsudhonimh discuss may have good insight for you. I suspect something is gong on where the walls will always need "to breath". I too, live in the southwest and there is a product American Clay that allows for that. You may want to investigate this product or find something similar that will give you wall color but, allow air and moisture to work with a colored coating applied to the wall. See wwwamericanclay.com. You will not be able to have the rich, vibrant color you have on the wall now but, you will eliminate the bubbles, flaws and peeling with a "natural" clay coating. The look is more subtle bur, still attractive with a lot of textural appeal. I have had at least one client use this product in his home and he said it was a lot of work to apply but, he was glad he tried it and he liked it a lot and would use it again. Worth looking into I think.

Is the soil around the outside of your house wet or moist most of the time? Could your neighbors have a water leak that is affecting your house? Is this the only wall that is affected?

It looks like water seepage. Is this a wall exposed to exterior on the other side?

hi..thnx for all the comments.ya my wall is made up of bricks and there is an open ground on another side of wall..i checked it for leaks and bushes growing over but there was nothing there.may be the moist soil on another side is doing so..what should i do to permanently prevent it??coz scrapping off leaves a groove and i dnt want it here.can i cover the groove with sumthng..

any ideas on that??

we put 2 layers of white puttey and 1 layer of primer and three layers of paint..

In American, code requires for structures to have a concrete foundation between structure walls and the earth. It sounds like you have a permanent problem as long as building walls are sitting on ground? Now would be a perfect time to post a picture of what you are saying. In this country 200 years ago in the American West at least, buildings were built directly on the earth but, that has been changed for many, many years. If you are saying there is no foundation and walls are directly in contact with the earth and ground then you will always have moisture conditions to deal with. I would direct you back to post by tsudhonimh for how to live with walls that need to BREATH.

Seek advice from a waterproofing expert in your area. Perhaps there is a crack in the groove abutting the wall or waterproofing around that wall and ground has started to fail over time. It's impossible to advice without seeing the actual conditions and you need local experts who are familiar with similar problems in your area.

I agree it's time to call in a professional. Any further attempts on your part will probably be a waste of time and money. I hope it's an easy fix. Your home is beautiful and you need to enjoy it and be free of worry!

The cause could be any of the things mentioned or something totally random that was in the putty. I doubt you have a permanent problem, but just something that happens during construction from time to time. I would scrub it and then let it dry for a week. Then paint it like you did the other one for now. Let your walls have some more time to climatize. Then, in a few months, or after the next rainy season to give it a good test, smooth it out with more putty for a finished look and repaint. Once it quits doing it, my guess is it will be done for good.

"coz scrapping off leaves a groove and i dnt want it here.can i cover the groove with sumthng.."

Scrape out all the bad stuff. Then use "patching plaster" or "spackle" to fill the groove flat, sand it smooth and level with the rest of the wall.

After it's completely dry, prime and paint the patched spot with the same paint.

PREVENTION:
This may have been water coming up through the walls from wet soil outside, or trickling down the wall and seeping through.

1 - Make sure the dirt on the other side of the wall slopes AWAY from your house for a couple of feet. The slope doesn't have to be extreme, but it has to be there.
2 - Check your roof and drains to make sure they aren't letting water trickle down the wall.
3 - Check the entire wall from top to bottom looking for cracks or missing pieces in the mortar that let water through. If you find these, fix them. (It's called "tuckpointing" and there are videos on YouTube showing how to do it.
4 - Also look for places where excess mortar sticks out and holds water like a tiny basin. If you find these, tap them with a hammer to knock them off.

ya i will do dat for now..i called an expert and he says its bcoz f moist soil on other side but that ground is of my neighbours and i cant help it out..i think there is only temperory relief and i ve to do it often like evry 6 months or so..there is no leakage but just moist soil and as in chromatography moist is getting soaked up on this wall...i hope my neighbours find sumthng to do wid ground..its a tropical area so lots f rainfall here!!

thnx all

help me here too

Your problem won't just go away! And more than likely your neighbors won't fix the problem unless they are also having the same problem. You need to get a professional to come in and make a plan to solve the drainage problem. The wall will continue to act as a wick and as time goes by more of the wall will show signs of being wet!

Now, I'd love to look at your other post! I had to get the wet wall idea out of my head! lol.

This Wiki article on damp( structural) may be helpful with some information on structural dampness, diagnosing rising damp properly and possible rectifications.

(the link doesn't load correctly. You need to copy and paste the entire link.)

it may be humidity , it's what it looks like , but also could be the primer used or that there was ones wall paper behind

If I understand the seasons in India correctly, you have already been through the rainy season. Don't wait until the next rainy season to get the problem with your drainage fixed. Now will probably be the ideal time to get it fixed. Please get someone who will tell you what to do and then have the work done. The paint on that wall in your beautiful home will keep coming off!

sure will get it fixed in next week
