The perceived quality level of the project is an important factor affecting people's judgment of the quality of the project, and it is very important for the owner and user to leave a good impression. Today we will tell you how to achieve high quality plastering projects.
Material inspection. 1) plastering engineering should be cement setting time and stability for re-inspection, general plastering should be ordinary cement, slag cement, pozzolana cement or fly ash cement, cement into the factory need to product name, code, net content, strength grade, production license number, production address, factory number, implementation standards, dates and other visual inspection, while acceptance certificate.
2) Grind the fine lime powder, control the cumulative sieve allowance of the sieve, and soak it in water before use to make it fully matured.
3) The sand for plastering is generally selected as a mixture of medium sand or coarse sand and medium sand, and the sand also needs to be sieved before use, and the mud content of the sand is reduced, and there are no harmful impurities.
4) The fineness of fly ash must be controlled, and the carbon content and loss on ignition and other indicators should be detected.
5) Plastering gypsum can be used to eliminate potential quality hazards such as hollowing and cracking as much as possible.
Grassroots treatment. 1) For the parts where there is a deviation in the flatness of the base layer, the parts with a total thickness of plastering greater than or equal to 35mm are treated.
2) Reinforcement measures are set at the junction of the wall and the beam and column, and steel wire mesh can be added, and the lap length is controlled to be not less than 200mm.
3) The wall masonry mortar should be hooked into groove joints to increase the bonding area between the mortar and the base layer.
4) Strictly seal the construction holes on the wall.
5) Clean up dust, dirt and other debris on the surface of the base layer, and carry out hair treatment on the smooth surface of the base layer. After finishing, sprinkle water to moisten.
Kick handling. 1) According to the plastered ash cake filling as the basis for wiping skirting or wall skirting and wall plastering, the bottom layer is plastered with 1:3 cement mortar.
2) Detect whether the thickness of the skirting or wall skirt meets the design requirements, and when there is no design requirement, the wall surface should protrude 5 7mm, and ensure that the protruding part is smooth and straight.
3) The corners of the skirting foot protruding from the wall should be made into obtuse angles, and the quality problems such as stubble should be cleaned and eliminated.
Corner protection construction. 1) The sunny corner between the wall columns should be used as a corner protector with 1:2 cement mortar before plastering the wall and column, and the height should be greater than 2m.
2) Wipe cement mortar on the side of the sunny corner, and clean up the excess cement mortar according to the width of the corner protection after trowel treatment.
3) The positive treatment of the yang angle is the same as before, and then the sharp corners of the corner protection are painted with plain cement slurry, and finally treated into an obtuse angle.
Closing phase. 1) The surface layer light collection time is the key stage of the whole plastering project, which should be carried out when the surface layer mortar has begun to solidify, so that the disturbance caused by the surface will not cause a large area of hollowing, and will not cause local falling.
2) When closing the surface, first wet the wall with water with rollers, and then file it with a hemp file, and then close the surface horizontally.
3) After the completion of the large-scale treatment, check whether there are cracks, falls and other diseases, and the plastering must be repaired in time. The actual plastering should be divided into the same batch of operations according to the temperature, so as not to cause the mortar to dry and crack.
The above is the detailed display of the construction of the ** exhibition hall project analyzed by Zhiye Cultural and Creative Construction Group for you.
