Guidelines for hardbound construction of construction projects Plastering of interior wall I. Preparations before plastering: 1Indoor plastering construction should pay attention to the reasonable arrangement of working procedures, indoor dotting, socketing and then the stability of wire boxes and electric boxes on the wall. After the stability of wire boxes and electric boxes is completed, steel wires are embedded in the pre-embedded pipeline (all the unopened pipelines are disposed of before plastering). After the above work is completed, the inner wall plastering is carried out. 2The surface of the wall should be cleaned up of oil stains, dirt, dust, etc. The surface of concrete and block should be treated with wool, and 1:1 cement mortar mixed with appropriate amount of glue slurry to ensure a solid bonding between the base and the surface.The protrusions on the surface of walls and columns should be eliminated. 3Prepare Yin-Yang angle ruler, prescription and paste ash cake to ensure the rectification of Yin-Yang angle.In order to ensure the same width of the interior window mesa, the inner ash cake is measured according to the plane of the outer wall to avoid big and small heads. 4Strengthened measures should be taken at the junction of indoor partition wall, concrete wall and beam. When plastering, 20 mm wide grooves should be reserved at the joints. The groove depth is the same as the plastering thickness. After plastering, the anti-cracking mortar should be filled densely with anti-cracking mortar. After the final setting shrinkage of anti-cracking mortar, 200 mm wide glass fiber mesh strengthening layer should be affixed. Before large area plastering, a layer of glass fiber mesh cloth should be affixed.All pipes, switch boxes and sockets should be packed in accordance with the requirements. They should be layered and embedded with 1:3 cement mortar, and the original reserved wall holes, including scaffold holes, should be sealed. 5Before the start of construction, the sample room should be made, and large-scale construction can be carried out only after Party A and on-site supervision and acceptance are qualified. 6Before the start of the construction, the site workers and team leaders should give a detailed account. II. Operating Technology 1The wall is watered and wetted one day before plastering. 2When plastering, it should be carried out in layers.Before plastering, the first time the thickness of plastering is 8 mm. Then the plastering is covered with a ruler and rubbed with a wooden plaster to erase the sand holes and holes.After the first time of plastering, the second time of plastering, the thickness of 6mm, with aluminum scraper flat, and then rubbed with wooden plaster, with a sponge to draw fine wool lines.Pubic corner plastering should be square and not distorted.And the Yin and Yang angles are all right and straight. 324 hours after the wall plastering is finished, necessary water spraying maintenance measures should be taken. III. Quality Standards 1The variety and quality of materials must meet the requirements of design quality and material standards. The bond between plastering layers and between plastering layers and base walls must be firm. There must be no delamination, empty drum, explosion ash and cracks (except cracks in wind cracks) in the surface layer. 2Surface smooth, clean, stubble flat, straight and clear line angle. 3The plastering around holes and groove boxes should be smooth and smooth, with accurate size, and the plastering surface behind the edge of the neat pipe should be smooth. 4The door width frame and the wall are compactly filled and the surface is smooth. 5Allowable deviation: The vertical surface is 3 mm; 2. The surface is 3 mm flat; the Yin-Yang angle is 3 mm square; the wall entrance straightness is 2 mm.
