Stair step marble paving

Preparation → bullet → trial assembly → number → brush cement slurry bonding layer → lay mortar → lay marble stones → fill joints, wipe joints → wax.

1. According to the elevation control line, divide the errors of all the steps of each segment of the stairs equally, and mark them on the wall as the standard for checking and controlling the elevation and position of the plate.

2, The stair surface plate material should be selected first (step should be selected to meet the requirements of anti-skid block), and according to the color and pattern classification stacked spare, shop paste should be based on the material situation before soaking wet, but the use of the surface should dry.

3, The soil of the base, floating ash.Ash to clean up, such as local uneven, should be in the shop before the spit gouge, concave with 1:3 cement mortar leveling.

4. Before laying and pasted, the facade and plane plate of each step shall be put into trial assembly and trial arrangement according to the pattern, color and parquet texture. After the trial arrangement, the number shall be numbered and put away for reserve.

5. Spread the semi-dry hard cement mortar of the combined layer, and 1:3 cement mortar is generally used.Before laying, sprinkle water to wet the base, with the brush of plain cement slurry with paving mortar, after paving with scraping rod scraping, patting, with a trotter pressed flat and dense, paving order is generally according to the first step facade, step facade, and then spread the stair railing and the color belt against the wall.

6, The stair plate material surface layer laying order is generally from the bottom to the top level of the paving, paste the facade first, after the paving of the plane, paving should be according to the trial, trial of the plate number of the number of the paving.

7. Before laying, the plate will be soaked and dried in advance for standby. When laying, the four corners of the plate will be placed on the semi-dry hard mortar layer with a good paving.

Use small wooden hammer or rubber hammer to hit the plate so that the four corners are flat, the seam and the flower meet the design requirements, and the seams are uniform, the color and lustre are consistent, and the surface layer is firmly combined with the base surface.Clean the surface layer in time and clean the seam.12h after laying at room temperature, start curing. After 3d, it can be pointed or rubbed.

8. When the design requires the use of white cement and other colored cementing materials, the white cement and pigment are used to make the colored cement slurry similar to the plate tone, and the special tool is used to point and compaction until smooth and smooth.

9, Wipe (hook) seam 24h with clean wet sawdust cover or spray curing is not less than 7d.

10, The stair skirting board: the skirting line with the ground with the same variety, the same specification, the same color of the block, vertical seam should be aligned with the ground seam, laying in the room at both ends of the shade corner of a brick, the wall thickness and height is consistent, and the top of the brick as the standard, hanging line shop.

Paving using adhesive method, will turn back up, full of 1:2 cement mortar, immediately pasted to the bottom of the scraped cement paste, squeeze flat, knock solid, make its upper mouth with the line, and at any time to squeeze the extruded brick surface of excess mortar scrape, the brick surface clean.Sun Angle block should be used 45° Angle seam.

11. Winter construction: the temperature of raw materials and operating environment shall not be lower than +5℃, the sand with frozen blocks shall not be used, and the surface of the plate shall not be frozen.
