1. Material requirements
The organization is required to be fine, solid, weathering resistant, no corrosion spots, no hidden injury, bright color, complete edges and corners, neat bottom, and can be polished. For the finished products processed by the factory, their varieties, specifications and quality should meet the design requirements and relevant standards, and have the factory certificate of quality. The cement shall be made of ordinary Portland cement or Portland cement no. 325 or above, and white cement for rubbing joints shall be prepared, and shall not be affected by moisture and agglomerate. Medium sand or coarse sand, should be screened, particle size should be less than 5mm, mud content is less than 3%. Oxalic acid, wax, etc
2. Main machinery and equipment
Mortar mixer, grinding wheel cutting machine, stone cutting machine, small table grinder, polishing machine, flat spade, alloy flat chisel, hardwood clapping board, wood hammer, iron trowel, rubber hammer, level, straight ruler, by ruler board, wood by ruler, etc.
3. Operating conditions
Roofing waterproof layer, ceiling, interior wall plastering has been completed, the door frame has been erected and protected, all kinds of pipelines and embedded parts have been installed, the floor drain has been covered, the pipe hole through the floor has been blocked solid block. The ground cushion has been made and its strength has reached more than 5.0Mpa. On the wall has played or set up control surface elevation and drainage slope of the horizontal reference line or mark. Clean, inspect, check and select the specifications, colors, varieties and quantities of granite. The same room with flowers, colors, varieties of selection size is basically the same, uniform color, smooth pattern for pre-weaving.
4. Operation process
(1) Construction process: preparation work a try to spell a bomb line a try row a brush cement slurry and mortar combined layer a shop granite stone a irrigation joint, rub a dozen wax a protective surface layer.
(2) clean up the base: the surface of the base ash, oil, slurry and debris clean up. Such as local uneven, should be convex chisel level, concave with 1:3 mortar fill level.
(3) Find elevation and elastic line: from the corridor to introduce elevation line in each room. Then in the main part of the room on the cushion layer play mutually vertical control cross line, and lead to the bottom of the wall, as the inspection and control of granite, plate position.
(4) test and row: before laying, try the granite plate of each room according to the pattern, color and pattern texture. After trying to spell, number them in two directions, and then put them neatly by number code. Check the plate for the gaps between the test plate, and metope, column, the hole position is in line with the requirements, such as general also try to make a row, in the room of two mutually vertical directions, with two wide plate dry sand belt, not less than 30 mm thick, the marble plate lined up according to your drawings, after try lined up number packed neatly, and removal of abrasive belt.
(5) Paving screed layer mortar: the thickness of the surface screed layer is determined according to the horizontal line, and the cross line is pulled to pave the screed layer cement mortar. The general use of 1:3 dry hard cement mortar, consistency to hand kneaded into a group, not loose appropriate. Before spreading moistening cushion, sweep water cement ratio of 0.4-0.5 plain cement slurry once, and then spread mortar from inside to the door, spread after scraping big rod, pat, leveling with a spade, its thickness is appropriately higher than the leveling layer thickness of 1-2mm according to the horizontal line.
(6)P, paving granite: paving sequence generally according to the line from the door to the vertical and horizontal and the room in a number of horizontal paving standards, and then partition according to the row and line paving, can also start from the interior side, row by block to the door entrance retrograde paving, but attention should be paid to the joint with the aisle ground should meet the design requirements. But when there is a middle column in the room, the column should be laid first, and then laid outwards along both sides of the column. When laying, it is necessary to "sit" according to the numbered plate of the trial and trial row. Before spreading, the plate will be soaked and dried in advance. When the shop will be around the plate at the same time square in the harsh leveling cement mortar layer prepared, try shop right after, opened the plate on the cement mortar pouring a layer of water cement ratio of 0.5 cement slurry, then put the plates gently on the in situ down, with a rubber mallet or wooden hammer tap on plate wood plate makes the board level, according to a horizontal line with iron level leveling, make the board smooth corners, Meet the requirements for sewing and flower; After the shop, then to both sides and backward direction sequence inlay shop, until the shop is finished. If the gap is found, the SLATE should be lifted with mortar and then laid. The joint between granite plate should be strict, generally the gap width should not be greater than 1mm, or according to the design requirements.
(7) filling and rubbing joints: after the board paving is finished 1-2h, it begins. Should be adjusted according to the color of the plate plate with white cement and pigment tone similar to 1:1 dilute cement slurry, into the small mouth slurry pot slowly poured into the gap between plates, flow in the edge of the slurry with a horn scraper feed into the seam, to the basic full so far. After 1.2h, use cotton yarn to dip pulp and rub the seam until smooth and smooth. Glue on the surface of the slurry with a wet yarn wipe. Joint width is larger person, appropriate uses 1: 1 cement mortar first (with fine sand) fill seam 2/3 plate thickness, press the color that designs a requirement again next with cement color paste inlay brush dense, brush the mortar that falls in board surface with gauze head conveniently.
(8) maintenance: grouting wipe sewing 24h after the application of clean wet sawdust cover, water conservation is not less than 7d. (9) waxing: polished granite in the combination of cement mortar strength to meet the requirements, the completion of each process is no longer human, before waxing. Waxing should achieve smooth clean bright.
(10)K: Stick granite skirting board: waxing the surface of the skirting board shall be carried out together with the floor. 5. Protection of finished products
Plate storage shall not be exposed to rain, long-term soaking water and sun, the bottom of the wooden pad, transport with light. After the finishing of the surface layer, the room is closed, and the passageways that cannot be closed are covered with straw MATS and plastic woven bags to protect them. It is strictly prohibited to mix mortar and pile up materials, paint buckets and other sundries on the finished surface layer. Indoor paint, brush pulp to protect the finished surface layer from pollution.
