The first step of room wall painting: major inspection When painting the room wall, major inspection is a very important part. For indoor cement walls, generally check whether there are any major defects in their walls. For the putty wall, it is necessary to verify whether the putty on the wall surface is waterproof. If not, you must redo the waterproof putty. If you paint directly without inspection, it is likely to bring problems to later life.
The second step of room wall painting: protection of finished products When painting, putty, paint or other glue will inevitably overflow, so it is necessary to protect the finished products from the room in advance.
Step 3: Make preparations before caulking to ensure that the wall is solid and flat. Brush the wall with a brush or other tools, so that the concrete wall will not settle and the floating dust will float.
The fourth step of room wall painting: scraping putty. Generally, putty can scrape the wall twice, which can level off and cover the bottom. If the smoothness of putty is low, it should be scraped several times in each part. If the flatness is poor and the wall is seriously inclined, you can scrape off the gypsum to make it smooth, and then scrape off the putty.
The fifth step of room wall painting: putty grinding is generally difficult to grind when water-resistant cement becomes particularly firm. Therefore, it is recommended to start grinding putty 1 0 ~ 2 days after scraping putty.
Step 6: Paint the wall of the room: brush the primer to clean the surface of the putty, and then brush the primer. Primer must be applied evenly at one time. Pay attention to indoor ventilation after painting the primer, so that some chemicals can volatilize better.
When painting the walls of the room, paint according to the above six steps, so that the final effect is satisfactory.
