6. Surface joint and seam wiping. After bonding, the surface mortar shall be wiped off with clear water in time, and jointing shall be carried out after 24-48 hours.

Six, wall tile facing

1, grass-roots treatment: clean up the mortar debris on the wall and chisel out the obvious prominent parts. The bottom mortar should be absolutely flat, and the angle of Yin and Yang should be absolutely square. Before laying bricks, the surface of the base should be watered and wetted, and then leveled with cement mortar.

2. Elastic line: according to the design requirements of the drawings, according to the layout of the doorway and the vertical and horizontal decorative lines.

3. Priming: Before tiling, the surface of the base should be watered and wetted, and then the cement mortar leveling layer should be painted. The bottom mortar should be absolutely flat, and the angle of Yin and Yang should be absolutely square.

4, tile paste: according to the design elevation pop-up horizontal and vertical lines, and then according to the design requirements and tile specifications to determine the width of the frame joint. Bricks are paved with plain cement slurry from bottom to top, which can be completed at one time. Brush cement mortar on the wet bottom layer before sticking the adhesive layer. At the same time, spread the brick on the wooden pad, coat it with a thin layer of plain cement slurry, and then paste it. After the unit brick is paved stably, the bending and torsion gap is adjusted with a metal dial before the cement mortar solidifies, so that the spacing is even. After all bonding layers are laid and finally set, caulking shall be done with thick white cement slurry, and the joints shall be wiped hard to make them full and dense.

Seven, coating engineering

1. Basic treatment: After the surface is cleaned, the wall shall be leveled with putty. After the putty is dry, first level the excess putty with a shovel, and then polish it with 1 sandpaper. Paper tape for panel stitching. Brush the nail head with antirust paint and smooth it with gypsum putty. Filled joint paste for internal corners.

2. Plate surface coating process

(1) Full scraping putty and polishing: After the large gaps in the indoor painting surface are filled up, full scraping latex paint putty with batch embedding tools, and all small sand holes and shrinkage cracks shall be fully scraped, which shall be subject to compactness, smoothness and neat edges. Scrape horizontally one by one along the wall, the thinner the better, no leakage, no seams, no fouling of doors, windows and other surfaces. Apply putty twice in turn. After the putty is completely dried, wrap it on a flat sand rack with 1 sandpaper, and smooth the putty paint and uneven places. Pay attention to the uniform stress and protect the edges and corners. Clean it up with a broom after grinding.

(2) Brushing: Before brushing, the surface of the base must be cleaned and the floating ash must be wiped off. The order of painting should be from top to bottom, from left to right, first horizontal and then vertical, then edges and corners, then facets and then facets. There shall be no residual paint in the internal corner and no wrapping in the external corner.

(3) Re-putty: After the paint is completely dried, it should generally be inspected. If there is any defect, it should be repaired locally.

(4) Polishing: After the patching putty is completely dried, fine sandpaper should be used to polish the surface of the coating film smoothly, and the force should be light and even, and the coating film should not be worn through.

(5) The second coating.

Eight, pasting project

1, grass-roots treatment: the grass-roots wall should be flat, the obvious unevenness should be repaired and leveled, and the smaller pits and stains should be filled with putty. The wall should be kept dry to prevent mildew after installation. The wall should be clean, free of dust and floating ash. And paint a layer of primer on the wall.

2, elastic line: horizontal and vertical, considering the symmetry and uniformity of wallpaper, the format is symmetrical. The first piece of paper on each wall should be arranged straight as a guide line, and the second piece should be pasted from top to bottom in turn.

3. Cutting: The wallpaper should be planned as a whole according to the material specifications and the wall size, and numbered in sequence. The cutting length of wallpaper should be slightly longer than the size of the pasted part100 mm-150 mm. ..

4. Paper pasting: Choose a good location and hang a vertical line to ensure that the first wallpaper is pasted vertically and evenly. Adhesive should be prepared as needed, limited to the amount of the day. Hydroxymethyl cellulose is first dissolved in water for about 10 hour, then filtered with fine pore sand to remove impurities, and then mixed with other materials and stirred evenly. The thickness of the glue solution is convenient for installation. Brush the glue evenly on the wall with a combination brush, then gradually put down the cut wallpaper into a roll from top to bottom according to the requirements of flowers, smooth the wallpaper with a wet towel and stick it firmly, and cut off the redundant paper materials from top to bottom with a blade. The installation can be carried out by grinding method. Two adjacent pieces are at the flat-fell seam, and the last piece is about 3cm higher than the previous one. Then, use a ruler and a cutter to cut through the double-layer wallpaper in the middle of the overlapping range, and tear off the two cut wallpapers. For wallpaper with patterns, in order to ensure the integrity and continuity of the patterns, the splicing method can be adopted when mounting, and the patterns can be spliced first and then spliced. After the patterns match up and down, scrape the glue obliquely with a scraper to make the flat-fell seam dense, and then scrape out the excess glue in the flat-fell seam and wipe it clean. For wallpaper with important overlap and matching, it should be mounted and matched first. After the glue dries to a certain extent, the remaining edges should be cut off, and then leveled and compacted. Use the knife evenly. Cut straight at one time to avoid knife marks. When mounting and collage, the internal corners should overlap, and the external corners should not have seams, so the corners should be compacted. Use the whole wallpaper in the obvious place on the wall, and stick one less wallpaper in the dark or inconspicuous place. The connection with the hanging mirror line, skirting line, face sticking and other parts should be close, and there can be no gaps. Then evenly drive the glue from top to bottom to discharge bubbles, and wipe off the excess glue when using.

5. Finishing: If local nonconformities are found, remedial measures shall be taken in time. If wrinkles appear on the paper, wipe it with a wet towel before drying it, flatten it with your hands, and then flatten it with a rubber roller. If the wallpaper is dry, it needs to be reworked and pasted again.

In short, the basic process of hotel decoration has the above eight items.
