Anonymous users2024-01-24"Waterproof gypsum board" can only be said to be water-resistant, and gypsum board has no "waterproof" ability. If the bathroom of the house upstairs in your house does not leak, then it is possible to use the exterior wall paint on the ceiling surface.

Anonymous users2024-01-23Answer: Not waterproof.
The real meaning of a gypscale ceiling is fireproofing. If there is a leak on the floor, you must negotiate with the owner of the upstairs in time, and you can't find the property.
For small quantities, short periods of time, yes. If there is a lot of water, you must poke a hole as soon as possible to prevent waterproofing!
Bathroom waterproof package material price reference: do js waterproof once 15 yuan square; Make polypropylene (TS) once 25 yuan square; To make oily polyurethane is generally between 40 and 60. To make gypsum board ceilings, the price of the construction is determined according to the difficulty of construction, which is generally 80 150 yuan square. >>>More
In the design of hotels, mansions and villas with high requirements for top shapes such as stacked levels and light strips, the top material of the bathroom is basically water-resistant gypsum board (note that water-resistant gypsum board is not moisture-proof), batch waterproof putty, and waterproof latex paint on the surface.
Personally, I think the bathroom is still not suitable for waterproof gypsum board ceilings. Waterproof gypsum board is gypsum board after all, and it also has a service life! The humidity in the bathroom is heavy, and it is inevitable that it is damp, and at the same time, there is no way to make a waterproof gypsum board ceiling! It is recommended to use integrated ceilings and aluminum gusset ceilings!
Although it is waterproof plasterboard, it can also be affected by moisture, but it is recommended to use other materials (such as aluminum integrated materials, etc.).
