Exterior wall plastering is an important part of construction engineering. It can visually reflect the quality of the project during project acceptance, so it is important to do a good job of plastering the exterior wall. If you work in construction, they must be familiar with external plastering construction technology processes and basic common sense external plastering materials, the decoration of the home network Xiaobian today to bring you a look at the exterior wall plastering construction process related processes I hope I can bring you some help.
The external plastering construction process is mainly the following steps:
I. Technical specifications for plastering construction of external walls
1. The materials, specifications, quality and other elements of construction must meet the specified requirements. The construction layers must be firmly bonded. It is not possible to have delamination, empty drums, no ash and cracks in the surface layer.
2, the surface of the gray layer is required to be smooth and clean, the joint is smooth, the line angle is straight and clear, and the hair path is uniform.
3, the design of the holes, grooves, wire boxes and other parts, after plastering to do the correct size, shape, neat appearance, smooth texture, the paved pipe should be plastered behind.
4, the width of the grid, the width and depth of the reserved gap should be uniform and consistent, so that the horizontal and vertical, smooth and straight.
5. The water flow slope of the clean water line and the drip water tank is correct, the drip line is straight, the depth and width of the drip tank are less than 10mm, and they are neat and uniform.
Second, the external wall plastering construction requirements
1. Base treatment: If it is a concrete base layer, add a layer of 1:1 porridge cement mortar to the surface, which is filled with 20% 107 glue for surface solidification, concrete and brick wall joints, steel layout Net, the general width is 300mm, the mesh size is 10mm×10mm, the floating ash and other impurities should be removed before the arrangement, and the steel mesh should be flat and tight.
2, straight, set of rules: according to the reference line that has been popped up on the wall, respectively, at the corner of the door window, åž›, wall, etc., vertical, set of plastering cake. The ash cake is filled with ribs, and the wall surface is filled with ribs to control the flatness of the wall surface.
3, the bottom layer of mortar: should be layered and covered with the filling of the ribs, and flattened with a large bar straight, wooden trowel to reduce hair, the first layer 12mm thick, 1:2.5 cement mortar.
4. Wipe the surface layer mortar: After the bottom layer mortar is wiped, the surface layer mortar can be wiped the next day, the surface layer mortar is 8mm thick 1:3 cement mortar; the cement is used for 3.8% purpose gold ace waterproof powder, 0.9kg Dura Fiber/m3 cement mortar, smoothed with the dividing strip, and scraped with the plaster layer and the dividing strip of the golf ball by the ruler or the small bar. It should be flattened horizontally and horizontally, and flattened with a wooden trowel.
5, drip line, trough: in the cornice, window sill, window sill, awning, balcony, pressing top and protruding lines on the protruding wall, etc. should be done on the slope, the following should be made of drip line (slot), flow and drip line ( The groove is not less than 40mm from the outer surface, and the drip line should ensure that it is super-directional.
6. Pipes that are buried through the waterproof layer of the outer wall. The pipe clamp is fixed in place before plastering, and it is forbidden to install after plastering.
7. Maintenance: The plaster layer of cement mortar should be cured under humid conditions.
Third, the quality requirements of exterior wall plastering
The allowable deviation is generally 1, the vertical of the facade: 5mm; 2, the surface is flat: 4mm; 3, the balcony angle is vertical; 4mm; 4, the balcony angle is square: 4mm.
Exterior wall plastering basic materials:
The basic materials for exterior plastering are mainly in the following three categories.
1. Cement mortar plastering: cement, sand, water;
2. Cement lime mortar plastering: cement, sand, lime, water;
3, tools: trowels, ash buckets, mixers, scaffolding.
The above-mentioned decoration home network Xiaobian introduced some aspects of the exterior plastering construction process and the basic materials of the exterior wall plastering. If you are a practitioner in the construction industry, this knowledge will give you some help. If you want to improve your business skills, you need to learn more in practice. I don't know if you are satisfied with the introduction of Xiaobian? If you still need more information, please continue to pay attention to our home encyclopedia!
