Because the wooden keel ceiling is put together by pieces of wooden shelves! The 90-degree angle is the splicing of the wooden shelf, there is a gap, if the gypscale board is normal on the top, just the joints of the gypsum board and the wooden keel overlap on a seam, so that there is no structural force!
Plus the wooden keel is affected by the weather temperature! In that case, no matter how you deal with it in the later stage, it will always be a crack! In order to solve this problem, 90 degree angles are cut with a whole wrench!
But the iron keel does not have to be like this, the construction process of the iron keel is different!

One is to try to have gypsum board joints in the corners; >>>More
The putty is usually polished twice, and you can see that the kraft shadow is too thin.
Laying direction, fixed transversely and longitudinally.
The strength performance and deformation of gypsum board are determined according to the direction, and the longitudinal performance of the board is superior to the transverse, so the longitudinal part of the gypsum board is not allowed to be parallel to the covered keel when the ceiling is suspended, and it should be perpendicular to the keel, which is an important measure to prevent deformation and cracking of joints. >>>More
Mix white latex or polyethylene glue with gypsum powder, but now there are anti-cracking products on the market that do not need to be adjusted, but the price is relatively high. And the effect is not as good as gypsum powder, fill the gap after adjusting evenly, and then paste gauze tape on the outside (kraft paper is better than gauze tape, there is a new type of fiberglass mesh belt), and then scrape putty.
1. Gypsum board against the crack of the wall, is the wall and gypsum board. >>>More
