Of course, you can level it, use cement mortar or mixed mortar to level, and then scrape putty, brush latex paint is very flat, the price will not be very expensive, cement mortar is 12 yuan per square meter, gypsumboard ceiling is about 50 yuan per square meter.
For prefabricated panel structure houses to make suspended ceilings, if you want to be thinner, it is generally suitable to choose lightweight materials as the first choice, and you can use wooden needles for the fixation of the roof. The drilling should be selected at the solid core of the plate, and the expansion bolt below No. 8 should be selected if the metal expansion bolt is selected, and the strength can be moderate to prevent brute force from damaging the prefabricated plate structure and forming holes. >>>More
It is still possible to make expansion bolt holes on the prefabricated slabs and load-bearing beams for the ceiling. This hole is relatively small and basically does not affect the bearing capacity of the beam plate.
The top latex paint is mostly used in caisson ceilings and original top decoration. The operation is divided into three steps: bottom treatment, re-brushing, sealing and priming, and topcoating. The order of operation is as follows: >>>More
