Wall Damage
Hi All DIYers,
Please take a look at this screenshot: http://prntscr.com/qrnfy5
I don't know what's this problem is called. How can I solve this?
I've used the painting a year ago to solve this issue by repaint all the walls but after six months this problem happening again.
Guys all your help will be highly appreciated.

Is this an exterior wall? I suspect moisture is migrating thru the wall causing the issue, if so, you need to stop the moisture on the other side of the wall.

First damp proof applied, after that, wall putty applied, and finally, Berger Robbialac painting used.
But it seems like the salt, damp is kept producing from the wall.

I have never seen a paint on water/damp proofing product that has held up for more than a few years. Eventually the water vapor pressure from behind pushes the coating off the wall. I bet you've got efflorescence or chalking of the concrete's surface so the surface that the paint was bonded to has come loose. It's sort of like trying to patch a hole in a boat from the inside. The water is always trying to push your patch off the wall. The only true fix I have seen work long term, as Marksr suggested is to stop the water on the outside.
