How To Prevent Moisture On Ceiling In Bathroom?


The two major factors in reducing condensation are air flow and heat. The best way to increase air flow around the bathroom is to open a window. By giving the warm, damp air a means of escape, it reduces the amount of water in the atmosphere and so reduces the amount of condensation.


Remember to install a strong, water-resistant base behind the tiled surface. Some options include polyethylene membranes such as KERDI — which prevent moisture from entering your ceiling through the cracks between tiles and stones. Another alternative is to trowel thin-set mortar or plaster over the tiles when setting them.
