Make sure the horizontal circuit along the circuit, 10 mm 10 mm. At the end of each construction must be checked and the heart essence of air monitoring stations.-The standby losses, electricity, water, ventilation, fire, information be located before the most recent tile demolition to avoid compromising the quality of building blocks. The electrical axis focus countries needed available before building the wall.-Maintenance of building blocks, according to the rules. When the new building should be built and cover the sunny rain, avoid shocks marks. Need lightweight rain spray a few times in the early days of building blocks to develop good intensity, avoiding the dried mortar correctly due to the water drain tiles. Construction of the mortar was ready digital type of gravel mixed, impurities, hotels. Do not use more than 1 hour, do not use the excess mortar back of previous batches. Grade level rate distribution and mortar right design.+ Do not go back on the newly built wall. Do not shock, vibrate switch, lean heavy objects to walls.2. plastering work-Plaster cement M50 # , 15, 20 must be ready for sand many times the type off the gravel hotels, impurities, finely mixed, use no more than 1 hour, do not reuse the excess mortar, the mortar mix of previous times.-Before finishing plastering must perform the following basic tasks:+ Locate and mold the entire wall before executing a warrant.+ Insert and insert all the waiting hole, hole electric water ... stucco concrete rubble.+ Wall plastering work was done after the wall has dried enough under the rules.+ Next to the column, the leading door ... to straight edge, square, right-angle pedestal bezel door are aligned to each other.+ Before the wall plastering must be clean and must be watered the entire wet surface with clean water. For the plastered area must be made meshing squares 1, 5x1, 5 m, use the dọi or to the benchmark survey of monitoring by the floor. From the standard mold of the proceeding for the other wall meshing. Plastering layer thickness guarantees in accordance with the requirements of the design, the legal process to ensure no birds, no cracks cuts flow, marks of plastering tools, uneven stain locally or other disabilities. The leading edge of the corner of the wall, the edge of the door is good, straight, perpendicular to each other. The wall plastered after 24 hours water spray must be legal according to the maintenance lasted several days.-The wall was plastered only when there has been rain-covered solarium.The work inspection in accordance with the current regulations: use size 2 m and light a torch to check the flat. Use ke 90o to check the angles of the wall together, taking the rod type to check the dense adhesion.3. The work of the son, baits3.1. Baits by the mixture of paints + white cement + admixture-We must first check the wall: dry, flat, dense, not chapped, as actinodaphne ellipticbacca warped ... not detect possible would have warped phenomena actinodaphne ellipticbacca is using electric cutters to remove the plaster and dry mortar, wait for the new one.-Cleaning, abrasive removal off the grainy, clinging dirt, grease ...-Use of materials designed to upset one on baits of the wall have been processed. -Mold material will fill all the openings, most lyty holes and compensate all convex concave. Use paper borders (2) polished surface). Keep baits, polishing paper 1st, after the same baits for the third-last ball paper Polish number 0.Note that you can use fabric to dry, then with the rough wet cloth to clean the surface of the wall Rails ... instead of paper borders.3.2. water Paint on the wall-Use type primer Onip-arcadia mat and interior paint, water paint 3 ORNesPaint types up the wall outside wall, in the ceiling, beams, columns, sanitized, clean the dust on the surface of the wall already.
