Definitions

  • the invention relates to the technical field of plastering mortar construction, in particular to a construction process of plastering mortar.
  • plastering mortar any mortar that is applied on the surface of buildings and components and the surface of the base material, and has the functions of protecting the base layer and meeting the requirements of use, can be collectively referred to as plastering mortar (also called plastering mortar).
  • Plastering mortar is mainly used for anti-crack protection layer outside the insulation layer in benzene thin plastering insulation system, also known as polymer plastering anti-cracking mortar.
  • plastering mortar when applying plastering mortar, it is mainly to apply the plastering mortar directly on the wall at one time after cleaning the wall. Controlled, it is easy to cause the final adhesion of the plastering mortar to be poor, and it is easy to fall off. At the same time, it is easy to cause hollowing and other connection of the plastering mortar during the drying process due to too thick one-time application, which greatly reduces the plastering quality of the plastering mortar. On the other hand During the plastering process, due to the inability to effectively level and seal the wall, the quality of the final surface mortar after construction is poor and prone to cracking.
  • the object of the present invention is to provide a construction technique for plastering mortar in order to solve the above problems.
  • a construction technique for plastering mortar which comprises the following steps:
  • Step 1 Base treatment: Remove dust, dirt, alkali film, mortar and other attachments on the wall, and sprinkle water to moisten it.
  • the prepared cement mortar can be evenly sprayed on the surface by chiseling and blowing.
  • On the wall use a grinding board to dry the rough surface.
  • a steel trowel to cross and draw oblique lines at certain distances on the surface. After the cement mortar is hardened, apply the bottom ash;
  • Step 2 Squaring and hanging straight: Before plastering the bottom layer, you must first perform operations such as square corners, leveling horizontal lines, hanging vertical lines, and popping up reference lines. For intermediate plastering, you can first check the wall with a mop board Flatness and verticality, and in the case of controlling the squareness of the sun angle and the crossing curve, roughly determine the thickness of the plaster and then hang the line. For advanced plastering, the room is firstly squared, and the cross line is popped up on the ground as a benchmark. Combined with the flatness and verticality of the wall surface, the position of the hanging line is roughly determined. After the wall is plastered, the supporting line is pier.
  • a standard pier When pierning, a standard pier should be made on each of the left and right corners, and then the vertical line of the hammer should be used to make the lower corner of the wall. Two standards, and then pass the line between the two standards on the left and right corners of the wall, and make several mortar piers at the upper and lower corners of the doors and windows at intervals of about 1.-1.3 meters;
  • Step 3 Wall punching reinforcement: After the mortar pier is hardened, apply the same mortar as the plastering layer, and make a 35-50mm wide mortar belt between the upper and lower mortar pier, and use the upper and lower mortar pier as a reference, and push it flat with pressing teeth After punching the rib tile city, the blocking and plastering operations can only be carried out after it is slightly dry;
  • Step 4 Make corner protection: According to the gap between the mortar pier and the edge of the door frame and the wall, after using a square ruler to measure, hang it straight at the outside corner twice, fix the ruler board, wipe the place with cement mortar, and use the outside corner Push out the small rounded corner with the trowel, and finally use the ruler to cut off the excess mortar at a position 50mm away from the male corner twice at an oblique angle of 45 degrees;
  • Step 5 Wipe the bottom layer and middle layer of dust: When the wall is wet, wipe the bottom layer of dust. For the surface of the concrete wall, brush one side of the cement slurry first, and then wipe the bottom layer of dust with the brush. After the bottom layer is slightly dry, use the same method If the middle layer of ash is too thick, apply it layer by layer, and test its verticality, flatness, and positive angle after application;

  • the sub-tweets are smooth and smooth, and the gray overlay of the paper bars should be bonded firmly without spoon marks, air bubbles, paper particles and uneven joints, and the internal corners intersecting with the walls or beams should be in a straight line;
  • Step 7 Apply cement mortar surface layer: The next day after the middle layer mortar is applied, use 1:2.5 cement mortar to plaster the surface layer with a thickness of 5-8mm. When operating, first wet the wall surface, and then scrape it thinly with mortar. Make it stick to the middle layer of ash, and then apply the second layer to reach the required thickness. Use a pressure gauge to level it out and straighten it. After it is closed, use a gray spoon to compact and calender;
