Does the ceiling gypsum board sunny corner need to be attached to the seam paper tape? Thank you,

Hello, this is the common sense of decoration, the joints of the gypsum board must be on the top of the secondary keel, so that the gypsum screws can be better fixed, so that the interface will not be cracked after scraping the putty powder.

Gypsum powder is mixed with white latex or polyethylene glue, but 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 gaps 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.

At the joints of the gypsum board of the ceiling, it is better to use the grid bag than the seam paper, because the toughness of the grid bag is higher than the seam paper, so the seam paper is easy to rib, and the grid bag is not easy to rib.

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
