As a green and environmentally friendly lightweight building material, aerated concrete wall panels are widely used in exterior wall panels, interior partition walls and roof panels of housing construction. Although the benefits of aerated concrete wall panels are many, the cracking problem of plastering panels is more prominent. Let's take a look at the places that need to be paid attention to in the plastering operation.
1. The plastering of the aerated concrete wallboard is generally a thin layer of cover ash directly on the base, so the basic structure of the wall is very important. When installing the wall panel, the position should be calculated to ensure that it is flat and firm.
2. The joints of the aerated concrete wall panels are generally controlled at two to three centimeters. If the board seam is too large, the filled sand will have greater drying shrinkage; if the board seam is too small, it is not easy to fill the mortar.
3. After the board seam treatment is completed, it is necessary to wait for a period of time before plastering, generally at an interval of more than two days, to give the mortar between the board seams a certain drying time.
4. Before plastering, the aerated concrete wallboard should be cleaned, the loose particles and protruding parts of the wall surface should be treated, and sprayed to moisten.
The above are the construction points of the plastering of aerated concrete wall panels. They are just some suggestions. I hope they will help you in your construction.
