3. Gypsum board shall be fixed in a free state, and the secondary keel shall be laid along the long edge. Self-tapping screws are 0/0-15mm away from the edge, 0/7mm away from the cutting edge, 0/50-170mm away from the nail, and 3-5 mm away from the gypsum board joint. Screws are screwed in vertically with a screwdriver.
