3.3.3 Before the inner wall is dust

3.3.3 Before the inner wall is dusted, first release on the ground the whitewash thickness of each room large sample lines, the dust thickness of the loft line from the wall is controlled within 1 to 2cm, the loft line must be angular square, the whole side of the yang angle.3.3.4 The roof measures its flatness before dusting, polishes and mends the unevenness of the surface, and then erases the ash as required.3.3.5 sets square, hanging straight, made of gray cake. Before erasing the bottom layer of gray must first find good rules, that is, four-corner rules, horizontal line to find flat, vertical line hanging straight, pop-up baseline and kick line, and according to indoor graying requirements to do a good job of gray cake.3.3.6 Wall punches, to be hardened, using the same mortar as the plaster layer. In the upper and lower gray cake between the line 30 to 50mm wide mortar belt, and above, under the gray cake for the ruler flattening, punching completed and wait for a little dry, before the wall bottom plastering work.3.3.7 do guard angle: according to the gray cake and door frame edge from the gap in the wall, with square ruler square, respectively, on both sides of the yang angle hanging straight and fixed the foot plate, wipe out the cement mortar guard angle, and use the yang angle smear to push out the small fillet, and finally use the foot plate, 50mm outside the yang corner position, with 40o angle to remove the mortar, clean.3.3.8 before erasing the bottom ash, in advance will be the wall wet, waiting for the wall when there is no open water on the wall to dump cement slurry (or brush interface agent), and maintenance, and then wipe the bottom ash, the thickness of the bottom ash is generally controlled at 5 to 7mm, until the bottom ash slightly dried, and then the same mortar to wipe the thickness of the middle layer of 7 to 9mm. After the middle layer of gray wipe to find flat and comprehensively check its verticality, flatness, yin and yang angle is square, straight, found that the problem should be repaired and dealt with in a timely manner.3.3.9 layers of plaster according to the design requirements mixed plaster, kitchen, bathroom and other veneer brick wall layer made of wool, other batch of putty wall press or shimmer.3.3.10 Key points of greying construction:Before smearing should check whether the window frame position is correct, and the wall connection is strong, aluminum alloy and aluminum alloy doors and windows used in the seam material should meet the design requirements, and the inlay is dense, and pre-paste the protective film, before erasing must first find good rules, that is, four corners Rules, horizontal line flattening, vertical line hanging straight, ejection baseline and kicking line, indoor wall, column yang angle and door and window hole yang angle, with l:2 cement mortar to wipe out the guard angle, and with the angle and cement sand The pulp is out of the small fillet; the grass roots should first use 1% caustic soda to clean the wall oil before smearing, and then use the water-doped weight of 2% 108 glue 1:1 cement glue to throw on the wall or top, finally watering maintenance Until the cement mortar moths are all glued to the surface of the crucible and have a high strength (until the hand is not moving), then the walls and roofs are dusted, and the brick walls and walls should be fully watered and moisted one day in advance before the ash is erased. Cement mortar surface laminated light must not be less than twice, and should master the pressing time, so as not to cause empty drums and hemp surface, cover the next day after the sprinkler maintenance. Paper-reinforced gray cover surface should be carried out in the base ash 5 to 6 dry, cover face is pressed twice to catch up with the light. Window sills, window stilettos, rain canopies, tops and prominent waistlines, etc., to strictly follow the detailed practices and requirements, careful construction, before the construction should play a good baseline, and the grass-roots to do careful treatment, to prevent the emergence of empty drums, skew, water, up and down the straight and other phenomena, resulting in rework.
