dry ground marble paved construction technical requirements

1) Stone (live loft, loft drawings admit, by the stone factory processed products) the types of standards, quality and construction standards should fit depicting needs.
2) Cement: Portland cement is usually 32.5 or slag cement, and prepare appropriate rub with a special seam sealant (color and stone control). If laying is light-colored stone, white  masonry saw blades  cement shall prepare white perlite.
3) sand: the sand or coarse sand (sand to golden yellow as the best, avoid using a large quantity of black sand mud) clay content <3%. Through a sieve aperture of 8mm.
4) stone dedicated posted agent, stone exterior protectant (proposition selection of imported goods).
5) Material: stone appearance filed proof testing representations guarantee the quality of goods, re-examination statement (per 500 square feet as a batch) quantitative detection of radionuclides statement, stone adhesive, protectant product certification, testing statements ( full chapter is useful in order to cover the red).
 
2, the operating conditions
1) should be stacked stone plate after playing indoors, Celi accumulation should be added under the skids party. And specific check type, standard, quantity, quality, etc. is not fit depicting needs, cracks, missing edge off angle shall not apply. Requirements cut holes of the concrete crack chaser  plate, before the processing of the device is good. Stone processing organizations in the OTC processing. Interior plastering, water pipelines and other equipment have been completed. Room near the wall playing good +100 cm horizontal line. Released before construction stone laying the ground construction large drawing.
2) After the appearance of stone to stone shovel to negative mesh, and then use the stone for six stone protector and face protection for disposal, dried and then for paving it.
B operating techniques
1, knowing Drawings: drawings and work orders to the basis, knowing that all parts scales and practices, to clarify the hole, corners and other parts of the linkage between.
2, try to fight: the official before laying, for each room of the stone (or granite) segment; should be drawing, color, texture try to fight. After trial spell placed at number two directions, and then press the number put regular.
3, the elastic line: The first part of the pop-up in the room with each other straight manipulation crosshairs to view and manipulate the orientation of the stone plate, can play in the crosshairs on concrete pads and lead to the wall at the bottom.
4, the test row: two each in the room straight direction, laying two dry sand, and its width is greater than plate thickness not less than 3cm. Demand based on drawings lined the stone plate in order to see the gap between the plates, check the plate and the walls, columns, such as the relative orientation of the hole.
5, the underlying self: paving stone plates in concrete pads before cleaning clean (including test row with dry sand and stone blocks), then watering moist, sweep again prime grout.
6, laying mortar: According horizon, set on the granite polishing pads  ground to do the leveling layer thickness ash cake locate, pull the crosshairs, paving screed cement mortar, leveling layer is usually chosen 1:3 cement mortar dry hard, dry and hard level to hand shape into groups not loose appropriate. Mortar from the inside toward the door at the paving, paved after scraping a large bar, making real, with the trowel leveling up based on the thickness of the horizontal line given proper leveling layer thickness.
7, paving stone blocks: usually in the room should be laid outside after that start with the entrance on the side away from the beginning, according to trial spell numbers sequentially paving, gradually retreat door. Shop before the stone plate paved dry hard cement mortar shop on the first test after appropriate, open slate, stone plates in opposite first full batch after batch of stone Posted agent grout, and then formally set shop. When placed together to the whereabouts of the four corners, with a rubber hammer or mallet tap wooden pallets (not a direct hit with a wooden hammer stone plate), according to the horizontal with a spirit level leveling blocks Puwan top order to set the direction of the sides and retreat Shop, if found open space should be filled stone mortar reuse lift device again. Stone plates, seams to be strict, leaving no gaps.
8, polishing Disposal: Disposal needs professional manufacturer for polishing. Some particularly high water absorption stone marble, crystal stone probably use disposal. Professional manufacturers based on the actual situation, please proceed.
C, Quality Standards
1, the master project
1), stone blocks used in the surface layer types, standards, colors and functions should be fit depicting needs.
2), the surface layer and the next layer should contact the firm, without hollowing.
3), decorative panels installation work embedded parts, the number of pieces of convergence, standards, orientation, cohesion and corrosion measures necessary to fit depicted disposal requirements.
2, usually project
1), the appearance of the stone surface should be clean, flat, no wear marks, and should clear picture, color common, uniform joints, surrounding straight, inlaid correct, crack-free plate, off angle, lack of flute and other shortcomings.
2), the surface layer of stone promise quality inspection standard error should fit the rules.
3) primary control data: Appearance Flatness: 2mm; straight stitch grid: 2mm; seams Bump: 0.5mm; baseboard catchy straight: 2mm; plate gap width: 1mm.
D, six-sided stone Protectant brushing is required to note:
Brushing is necessary to be protective stone water stone dry before brushing. If water has not yet dry, duration rushed the case, you can first brush five surface protectants, the front end of the project to be completely stone surface moisture transpiration before doing the final disposal of a positive stone protector, crystal stone eventual disposal. If brushing stone Protectant disposal was not good, the water will shut down in the stone stone ran out, constitute a stone in water retention shadow, once constituted the water film, the kind of quality problems will be very difficult to deal with and correct it.
