Decoration, how to solve the transparent scale of gypsum board ceiling?

That is the top surface of the moisture, water vapor, there is a wooden keel where there will be white, no keel will be dark, the reason may be that the roof ventilation is not good, the quality of the gypsum board used in the ceiling is too poor, the solution: 1, the cost of re-ceilinging is too high 2, re-scrape putty, paint, treat the symptoms but not the root cause, in a few years will be like this, 3, if it does not affect the use, make do with the use of it,

It must be damp, so first check the cause of the dampness when you recuperate. If you don't want to redo it, you can consider rolling paint to cover up the marks and protect the surface from moisture.

Also, don't buy low-quality gyppool board in the future, good drywall will not cause too many problems.

The solution to this kind of situation has to see whether the surface of the current gypsum board is flat, and if it is possible, see whether the quality of the previous wooden keel can be seen through the inspection port, if the two premises are no problem, it can be simply processed: one is to continue to hoist the quality of gypsum board or calcium silicate board under the original top surface, this method can restore the previous decorative effect; The other is to directly hoist the plastic steel plate under the original top surface, this kind of ceiling is light in weight and good in construction, but the effect is different from before. The method of suspended ceiling is to directly drive self-tapping nails to fix the new plate along the ground method of the log keel.

The solution is simple: brush it with latex paint and you're good to go.
