Hotel restaurants will be renovated when they are renovated, or after they have been in operation for a long time, and the project will not be completed in a short time. In the renovation, under normal circumstances, the wall construction will choose to brush latex paint or directly use wallpaper. However, due to the long construction period, it is difficult to guarantee the construction quality. Here, the brand building of Shanzhi Catering will teach you a few tricks, so that everyone can have a specific understanding of how to ensure the quality of wall construction. Before decoration, the wall should be inspected to determine whether it is necessary to shovel the wall, and the construction materials should be selected according to the situation. Here is a brief talk about how to determine whether it is necessary to shovel the wall: after the wall is sprinkled with water, use a shovel to hang the wall. If it is difficult to remove it, it means that the wall is a cement wall; On the other hand, if it is easy to eradicate, it means that the wall is wet and powdery, and the project containing formaldehyde is watered, so it is necessary to eradicate it. The next work to be done is to seal the solid layer. First, clear the empty drum, soak the white layer of the wall with water, shovel off the wall skin, then roll the interface agent on the wall surface to clean the floating ash, improve the adhesion, repair the empty drum, slot and five holes with leveling repair mortar, and caulk the gypsum for joint treatment. Check the flatness of the wall surface. If the flatness of the wall surface meets the standard specification (3 mm), it is unnecessary to wake up the thick leveling treatment with leveling repair mortar. It is more feasible to use milk putty for fine leveling directly. Fine leveling needs to be done according to the construction instructions of putty, and attention should be paid to sufficient and uniform mixing, batch scraping thickness and polishing, etc., to avoid problems caused by improper construction technology. The specific requirement of fine leveling is that the flatness of the wall after treatment is 1 mm. After finishing the above work, you can polish the putty and prepare for the following work. The next work depends on the situation. If you choose to paste wallpaper, you only need to brush a layer of basement membrane, and you can paste wallpaper after the basement membrane is dry. If you choose to brush paint, after polishing the putty and cleaning up the ups and downs of the surface, you can brush the alkali-resistant primer, and then apply it for the first time with a paint roller. Depending on the dryness of the surface, apply it for the second time after two to four hours. After the second finish painting, you need to wait for one or two days until it is completely dry. At the same time, don't forget to do waterproof, drought-proof, dust-proof, fresh air and sun-proof work before the paint is completely dried to prevent problems with the paint film. After completing the above work, the whole project is basically completed, leaving only the last step of acceptance. The specific acceptance rules are not the core of the topic to be discussed this time. The basic standards are that the wall surface should be solid, flat, with vertical angles of yin and yang, no cracks, no holes, uniform color, full paint film, and seamless and bubble-free stitching of wallpaper lines from a distance.
