One of the advantages of double-layer gypsum ceiling: the fireproof and moisture-proof performance of double-layer gypsum ceiling has a strong protection ability for houses. Although fire prevention is not practical, in the future prevention, after all, more than one ceiling may have an extra layer of safety. Dampproof is a big problem. Tide can be said to have always existed in the house. Humidity will bring inconvenience to people's lives and cause great damage to houses.
The second advantage of double-layer gypsum ceiling is that it can improve the crack resistance and moisture resistance of ceiling. The construction of double-layer gypsum board needs to be covered with polyethylene emulsion to really play its role. When the whole suspended ceiling structure is deformed, it can increase strength and prevent cracking. The final decorative effect of adding a layer of gypsum board is the same as that of single layer gypsum board. Another factor affecting the top surface cracking is the surface latex paint and other processes. There is a big gap between single layer and double layer. When water enters the dry wall in the ceiling, most of the water vapor will be absorbed and then slowly volatilized, which will not affect the effect of the surface coating.
One of the installation of double-layer gypsum ceiling: gypsum products should avoid contact with water as much as possible and should not be stored in the open air. Waterproof and moisture-proof measures must be taken. When transporting and installing decorative gypsum board, please handle it with care and pay attention to cleaning. If the product is contaminated, white or other required tones or coatings are required after installation.
Installation of Double Gypsum Ceiling (II): Conduct a comprehensive inspection of its installation model, size, founder, thickness and surface flatness. If it does not meet the requirements, it should be repaired and replaced in time. In order to prevent the plates from moving, there should be a certain gap between the plates during installation. The main reason is that the water in the space is not dispersed and the ventilation problem is not solved. Therefore, decorative gypsum board should be placed in a ventilated and dry room to prevent deformation due to moisture.
The third installation of double-layer gypsum ceiling: During installation, the interface between the panel and the base plate should be staggered and cannot be butted at the same position. Docking of gypsum board shall be handled according to product requirements. Gypsum board is fixed on the keel, and it should be fixed from the middle of the board to the periphery. Multiple points are not allowed to work at the same time. The buried depth of the nail is slightly embedded in the surface of the nail head, which will not damage the paper. Pinholes should be derusted and coated with gypsum putty.
The fourth way is to install double-layer gypsum ceiling: the fireproof and moisture-proof performance of gypsum ceiling has a strong protection ability for the house. Although fire prevention is not practical, in the future prevention, after all, more than one ceiling may have an extra layer of safety. Dampproof is a big problem. Tide can be said to have always existed in the house. Humidity will bring inconvenience to people's lives and cause great damage to houses.
The fifth installation of double gypsum ceiling: it can improve the crack resistance and moisture resistance of the ceiling. The construction of double-layer gypsum board needs to be covered with polyethylene emulsion to really play its role. When the whole suspended ceiling structure is deformed, it will increase strength and prevent cracking. The final decorative effect of adding a layer of gypsum board is the same as that of single layer gypsum board. Another factor affecting the top surface cracking is the surface latex paint and other processes. There is a big gap between single layer and double layer. When water enters the dry wall in the ceiling, most of the water vapor will be absorbed and then slowly volatilized, which will not affect the effect of the surface coating. The above is the introduction of the advantages and construction methods of double-layer gypsum ceiling.
