② The gypsum board is fixed on the secondary keel and cross brace with self tapping screws, with a nail distance of 150-170mm and a nail distance of 10-15mm from the board edge.
③ When installing double-layer gypsum board, the joints between the two layers shall be staggered, which shall not fall on the same keel, but shall be staggered by 300mm;
④ When laying and nailing gypsum board, fix it from the middle to the periphery of each board, and do not work at multiple points at the same time;
⑤ Nail holes shall be embedded in the board surface for 0.5-1mm, and coated with antirust paint and plastered with putty;
⑥ Add a layer of yarn cloth to the putty on each plate, and then scrape a layer of smooth putty
