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.

Hello Sujeeta, Take care of the waves in the wall while preparing the base . The reason behind this is, when you finish the wall with the wall paper the waves in the wall is noticeable or the gap creates the bubbles in that particular area. Practically go for the pop putty or the gypsum sheet fixed for the perfect finish.

Hi Shivam, the backdrop for a wall mounted TV depends on a lot of factors like placement of TV wrt window, size of wall, volume of the room and overall length available. You must first check the wall for leakages so that mounting the panel and TV does not cause damage in the future. Accordingly, you may decide to do waterproofing, if required and finish it in POP for a clean undulated surface or finish it in a matt finish material in either wood, veneer, custom - fit panel boards, marble or glossy look in PU / lacquer. In case you want to make it cost effective you may go for wallpaper/vinyl.
