15. Ash patches
15. 1 discrepancies are allowed for wall plastering: the vertical vertical level allows a 4mm surface flatness and 4mm yang angles allow for a 4mm wall mass deviation to be compared to the 4mm wall mass of the owner, to the extent allowed for the physical examination of empty wall drums: the one-sided wall allows an area of 5 cm of empty drums at 5 m2; the one-sided wall allows an area of 5 cm of empty drums at 5 m2 and allows an area of 5 cm of empty drums each; when an empty drums or cracks need to be repaired, the plaster layer should be sawed beyond the empty drums, the edge of the cracking 50 m and the ground should be removed, a piece of sand should be removed manually, residual powder removed, and the cut surface of the dust plaster should be removed and cleaned。
15. 2 remedial slurry recovery should be comparable to the slurry mix used for large areas of plastering, and should not be of a greater or lower intensity than large areas of slurry. Before we wipe the ash, water and moist the floor of the wall, then a layer of solid cement mixed with environmentally friendly glue, which is suitable for the ds-m15 cement ash, which is controlled at about 7 mm each time and is not too thick, then grazes the surface; and then wipes the surface the next day, which is better than the ds-m20 cement slurry, which is solid on the surface, and prohibits drying the surface or painting the concrete. After the dust has been wiped, the patches shall be protected by specialized water spills, which shall not contaminate or damage the parts of the surrounding area that have been scraped. The maintenance was reviewed one week later to confirm that no empty drum cracks were necessary to carry out the next process. Painting of environmental glue at the grass-roots level before shaving the accelerants is done. The patched ash layer intersects with the original ash layer in order to prevent cracks from occurring and spreading to affect the face layer. The patched plaster layer is fitted with a grid that connects to the original undivided part and is not less than 100 mm wide。
