1 After pasting the bottom layer of the grid bar or the mat layer, when the mortar is 6~7 dry, according to the design requirements, the elastic line determines the position of the grid bar, but it must be noted that the strip size is uniform and the vertical bars are symmetric. The height of the section of the wooden strip is the thickness and width of the overcoat layer, which is made into a trapezoidal narrow outer width. The partition strip is soaked in water before sticking to prevent the strip from expanding after plastering; when pasting, it is used on the grid The cement slurry is firmly bonded; it should be horizontal and vertical after being pasted, and the joint is tight and smooth. 2 wipe the surface stone slurry in the bottom layer or the cushion layer to achieve a certain strength, after the separation of the grid strips, depending on the dry and wet degree of the bottom layer, watering and moistening as appropriate, first thin and uniform scraping of cement slurry together, this is the key to prevent empty drums . The thickness of the squeegee is about 1mm, and the squeegee is followed by a steel trowel to wipe 1:2~1:2.8 cement stone slurry (depending on the size of the stone particles, if the small eight grains should be 1:2.5, such as with the use of the beige stone It should be 1:2.8). Sample test should be done before operation, and appropriate amount of lime slurry can be added for convenient operation. In each of the compartments, slap from the bottom to the top with the slap, use the trowel to repeatedly smooth the compaction, and gently flatten the exposed stone sharp edges to make the surface press the cement slurry. When wiping the stone slurry on the wall surface, it is slightly higher than the grid strip, then brush the surface to float the surface with a brush, pat the light and press it again, then brush and press it again. This is not less than three times. During the process, the stone rotates in the mortar, and the large face is facing outward and the surface is arranged closely and evenly. In order to solve the obvious smear after the surface layer is alive, after the stone slurry is pressed, a small roller with a diameter of 40 to 50 mm and a length of about 500 mm can be used to make a small roller, roll back and forth several times and then level with a trowel. Easy to lift the pulp, while the compactness is also good. At the corner of the sun, hang the vertical line, temporarily fix it on one side with the wooden slats, and set the height of the overcoat on the other side. Then wipe the ash paste. After wiping the side, use the ruler to lean against the stone paste. On one side, do the unsmeared side, and the joints should be staggered to avoid black edges. The yin angle can be gently tapped by the shaman's yin angle to make the yin angle straight. Now we generally use the practice of adding a vertical grid at the corner of the yin, which can achieve more satisfactory results. 3 Spraying brush is the key process of water brush stone. Spraying is too early or excessive. The stone surface is too easy to fall off when the mortar surface is exposed. If the spray is too late, the mortar is not washed properly, which causes the surface pollution to affect the appearance. The spray should be carried out when the surface layer has just started to condense, that is, it is better to use a finger to press no trace or brush the stone without falling off, which is the key to ensure the quality of the spray. The brushing action of the water brush stone wall is fast. One person in the front uses a soft brush to rub the surface mortar off, revealing the stone and avoiding the falling of the grain. The latter one uses the sprayer to spray the adjacent parts first. Then, the water spray is washed from the top to the bottom, each section is about 80cm, the nozzle is sprayed evenly from the wall surface by about 10~20cm, and the cement slurry on the surface is washed away, so that the exposed particle size of the stone is about 1/3. . When spraying the corners, the nozzles should be sprayed at an oblique angle to keep the edges sharp and tidy. Flush should be moderately too fast, too slow or leaky. Local stone particles are uneven when sprayed, and gently tapped with iron trowel to achieve uniform surface stone particles. If cracks occur, use a trowel to clean the surface of the cement slurry and expose the stone. Rinse the top and bottom with a small kettle. After removing the grid, the upper and lower parts should be cleaned. The stone can not be pressed. On the wall surface after spraying, use 1:1 cement mortar to make the concave depth 3~4mm and color. It is best to add color in the cement mortar and mix it evenly before caulking to increase the appearance.
