Hello Jagriti, For internal walls , you may want to identify and fix the source of dampness to avoid recurrence. You may then treat the wall with 1 coat of Asian paints damp guard or Dr Fix it damp-proof solution and then with putty mix of same material followed with 2 coats of this paint again. Follow the instructions as given on respective products. Thanks, Nitin CORNERSTONE DESIGNS Bangalore.

Anita Vitrified tiles by themselves do not particularly allow the walls to breathe, and hence are prone to cracking. That being said they do not collect moss either. If you are however set on using these tiles, I suggest you use them in a mosaic fashion, where smaller tiles or broken pieces are used. This will allow the wall to breathe, though the moss collection might be more due to the greater amount of grating.

I am not sure if this project is over, But try zinc sheet it looks great and gives you an industrial look.

not really reason its not very good or eco-friendly material as far as bedroom is concerned
