Paving gypsum board under the tiles in hardcover room can protect the tiles from damage. Before gypsum board installation, pay-off should be started according to the position of the wall surface, and the wall line should be set out at the ground position and lead to the roof and side wall of the house. Before the construction of the wall mat, the contact between the wall mat and buildings and the ground should be cleaned to avoid stains on the surface.

Matters needing attention in laying gypsum board

Apply a layer of interfacial agent on the surface, then pour C20 concrete on the wall, and evenly coat the concrete surface. Then after installation, fix the keel along the ground and along the top, and then fix it with nails. Each nail position should be 900 mm apart. Pay attention to the position of the nail when fixing, and avoid the position of the concealed pipe laid on the wall to avoid breaking the water pipe.

When installing vertical keel, we should also pay attention to the installation spacing and keep a certain distance, so as to ensure the stability of gypsum board. Draw a line on the keel along the ground and the top, and arrange the vertical keel from both ends of the wall according to this line. If windows are installed on the wall, they should be arranged from the windows to one side or both sides. The upper and lower ends of the vertical keel should be fixed to the keel along the ground and the top, preferably with rivets.

Finally, the installation can be started, and the installation should be arranged vertically. When installing gypsum board on both sides of the keel, the gap should be staggered, and the gypsum board and keel can be fixed with screws.
