1. If it is a micro-arc wall, the gypsum board can be directly fixed on the keel, and the deflection and deformation of the board itself are enough for that arc bending.

2. The deflection of the plate is not enough to reach the radian you need. Cut a V-shaped groove (lengthwise) on the back with a utility knife and fix it.

3. Just cut the gypsum board into slender strips, and then polish them into circular arcs with gypsum caulking, which is common in column wrapping practice.

Precautions:

Arc (concave-convex) construction method: firstly, make the joinery board into an arc, connect the formed joinery board with keel (wooden keel or light steel keel) at a suitable position, and then paste gypsum board on the joinery board and keel. The following picture shows the basic practice of arc (concave) roof, and the practice of arc wall is the same as it.

If the radian is not large, you can directly bend the gypsum board into the required radian; If it is slightly larger, you can spray a small amount of water or wipe it to bend it; No matter how big the radian is, it needs keel encryption, gypsum board splicing and then leveling with putty.
