If you don't pay attention to the importance of the wall, carelessness or procedural errors during the construction, it may bring a lot of inconvenience to your life after moving in. Whether it is painting or wall decoration, there are key points to pay attention to, and many problems need to be paid more attention to when painting walls in spring.
■ Seasonal
Allow enough time for the wall lining to dry.
Under the influence of climatic conditions such as moisture content and temperature change all the year round, it is inevitable that cracks will appear in the wall of newly renovated houses. However, in the spring when the air humidity is high, cracks are more likely to appear if the base is painted before it is dry. Therefore, we must pay attention to the grassroots treatment when decorating the wall.
According to Wang Xiangmu, the engineering department of Kuoda Decoration Company, the wall lining has to be scraped three times before the wall finish can be painted, and the normal drying time between each pass is 1 to 2 days. Spring is a rainy season, and the selected wall ash must be waterproof, moisture-proof, powdery and moldy. If you scrape the wall in rainy days, wipe the water vapor off the wall with a dry cloth and try to keep the wall dry. At the same time, the drying time of wall lining should be extended as much as possible according to the actual weather conditions.
Ma Bingyin, the chief designer of Kuoda Decoration Company, told the reporter that due to the hot flashes in spring, after the paint absorbs the moisture in the air, it will produce a layer of fog, which will make the paint emulsified and whitened. Therefore, in spring, we can consider using desiccant to make the paint dry faster. There are many details that need to be paid attention to in spring decoration, such as buying latex paint and adhesive, which must be flexible.
■ Quality inspection
The joints of the walls should be installed together.
According to Wang Xiangmu, the engineering department of Kuoda Decoration Company, according to different wall types, there are different methods and know-how to check wall projects.
Partition wall: generally speaking, it refers to a partition project with light steel keel as the skeleton and gypsum board, cement pressure board or plywood as the cover panel. This kind of project should ensure that the varieties, grades, specifications and colors of materials used must meet the design and current standards. Inspection can be done by observing, pulling by hand, measuring by ruler, and checking the product certificate.
Advanced plastering wall: including lime mortar, cement mortar, mixed mortar and other advanced plastering projects. This kind of project must first ensure that the plastering base meets the standard and the position of the columns in the column group is correct. Secondly, the plastering surface should be smooth, clean and uniform in color. Third, the plaster size behind holes, grooves and pipes is reasonable. The above contents can be observed with eyes, touched with hands, struck with a small hammer and checked with a ruler.
Paste paper decoration: wallpaper, wall cloth and other decoration projects. The varieties, grades, properties, specifications and colors of surface materials and auxiliary materials must conform to the interior decoration design and fire protection regulations of buildings. The inspection method mainly depends on naked eye observation, and the glued veneer should have the same color, and there is no glue mark and obvious indentation in the direction of orthogonal projection and oblique projection; The splicing place is horizontal and vertical, away from the wall 1m, without flat-fell seam on the wall; Sticking panels, skirting boards and other splicing places are closely connected.
■ Speaking from experience
Large core board needs to adapt to the drying time.
● Ai Yuzhou, carpenter.
The large core board requires clear and smooth texture and no knots on the surface. In fact, the decoration process of large core board is very demanding, especially in wet spring, which requires enough space for wood to adapt to natural drying and strict drying process control through drying kiln.
Paint should be dehumidified by air conditioning in spring.
● Wen Shasha, department head
Because my home was decorated in spring, the latex paint used on the wall surface dries slowly and tends to be moldy and stale. So the foreman taught me a solution, that is, after the construction, turn on the air conditioner to completely remove the moisture in the air, and the effect is really good.
Painting needs clean environment and tools.
Song Yang, a teacher.
Not long after my home was renovated, the walls were blistered. Later, the decoration company redone it for me and told me to avoid painting in the humid season. Besides, I have to wait for the putty or paint film to dry before painting the next layer. The most important thing is to clean up the construction environment and painting equipment before painting construction.
