3.2.10 Large-area lime plaster surf

3.2.10 Large-area lime plaster surface should be tested in the laboratory in advance, and the consistency and setting time that can guarantee the quality and facilitate the operation can be obtained before construction.3.2.11 General plastering is divided into three levels: ordinary, intermediate and advanced according to the quality requirements. Our company uses high-level plastering construction: find the square at the yin and yang corners, set up the standard ribs, level up in layers, trim, and calender the surface. 3.2.12 Plastering of kitchens, toilets, roofs, etc., where flooding is required, should be made into a flooding slope inclined toward the outlet. 3.2.13 Medium sand should be used for plastering, and it should be sieved before use. Extra-fine sand should not be used. 3.2.14 Lime paste for plastering shall be made with massive quicklime, and must be sieved with a sieve with an aperture of no more than 3mm×3mm during the pour, and stored in the sedimentation tank. Maturation time: generally no less than 15 days at room temperature. When in use, the lime must not contain uncured particles and other impurities. 3.2.15 For the concrete wall surface is relatively smooth, in order to prevent the occurrence of large hollowing and other quality problems, measures have been taken for this: polish the smooth concrete wall surface, and then clean, moisturize, and shake the wall (or spray slurry) as required. Interface agent), watering and curing, plastering and other processes. 3.2.16 Before construction, a prototype (sample room) should be made in advance and approved by the company's quality management department before proceeding. 3.3 Plastering the wall with cement mortar or mixed mortar 3.3.1 Before plastering, the pipe holes passing through the wall and floor must be embedded and filled, and the back of the pipe should be plastered before installation. 3.3.2 Prevent cracking at the junction of different structural bases: due to the different deformation values ​​of different structural bases, the stress generated is very easy to crack the surface layer. If the top brick of the masonry is not strong, the surface layer will crack in this part. Therefore, add steel wire mesh or alkali-resistant glass fiber mesh to these weak parts, and the steel wire mesh spans 150mm across the base layer of the structure on both sides. At the same time, the management of the construction of the masonry top bricks should be strengthened to prevent the loosening of the top bricks. Schematic diagram of steel mesh hanging:
