gypsum false ceiling is a lot better nowdays . it is easy to install and uninstall . There are different types of gypsum boards available in the market like plain, water resistant / moisture resistant etc ... Make sure to buy good quality gypsum board for better durability .

living/dining/kitchen it's an open layout like in one of the images. the ceiling is uneven so we are planning to get it fixed with re-plastering. I might not be able to get a skilled painter in my budget to get the textures right, so I thought by just applying a coat of cement I wouldn't need a very skilled worker and also get the industrial look.

Shailesh, Although it is NOT a recommended thing to do but should you install a gympsum board under a water exposed area - Please ensure that 1- The cement board slope is tested for leakages and painted with waterproof lining. 2- Use only Gyproc Glassroc H board for false ceiling 3 - It will be better to use Water proof Grid Ceiling than a regular ceiling for future maintenance and repairs. As there are many finer details, please get it done under supervision of a trained professional. Thanks, Nitin
