Matters needing attention in decoration and wall painting

Matters needing attention in decorating and painting walls Step 1: Check. Comprehensively check whether the cement wall to be painted in the blank room is solid and flat. If the plastering layer on the wall is not firm enough or there are big cracks and holes, it is suggested to complain to the developer or property and ask them to redo it. If individual holes are repaired by themselves, they can be filled with gypsum.

Wall inspection

Checking whether the wall is solid and flat is a step to check the house. Find a hard object (such as a key, screwdriver, etc.). ) and draw a line on the wall to see if there is any slag. There is no shortcut to finding cracks and loopholes, only care and patience.

Finished product protection

There will be dust when the wall is treated, and it is inevitable that putty, paint or other glue will drip, so we must do a good job in protecting the finished interior decoration products in advance.

♂? Preparation before scraping putty

Ensure that the wall surface is solid and flat, and clean the wall surface with steel brush or other tools, so that the cement wall surface has no floating soil and floating subsidence as far as possible. Roll the concrete interface agent evenly on the wall as far as possible, and after it is dried (generally more than 2 hours), you can blow putty.

Joint with putty

Before blowing putty, measure the flatness of the wall (with a measuring ruler of more than 2m) to determine the method of blowing putty. Generally, putty can be scraped on both sides of the wall, which can both level and cover the background color. Putty with poor flatness needs to be scraped several times locally. If the flatness is extremely poor and the wall is seriously inclined, you can consider scraping gypsum for leveling first, and then scraping putty. The interval between each batch scraping of putty should be more than 2 hours (after the surface is dry).
