1. Wallpaper Construction Program Wallpaper Paste is the decoration method often used in home decoration. The standard construction procedures are: sweeping the base layer, filling the embossing, gypsum board surface seam joints, putty, matte paper → Full of scraping, smoothing → brushing moisture-proof agent → brushing primer → wallpaper, brushing adhesive on the grass-roots level → squeezing → wiping glue → cleaning and trimming.
Wallpaper paste is a key link that affects the quality of the entire home decoration project. It must be constructed in strict accordance with the standard procedures to ensure quality.
2, the construction of the wall paper paste application specification At the time of the primary treatment of the air crack site should be chiseled redone, full scraping child should be at least two times, will stomata, pitting, uneven filling smooth and smooth. Every time the putty is thin, scrape it and scrape it again. The seams of the base materials of different materials must be attached to the seam tape. Should pay attention to the angle of yin and yang, under the window sill, after the dew channel, the upper edge of the skirting board, etc., must be clean, smooth and smooth.
Brushing dampproof agent is to prevent the wallpaper due to damp off, moistureproof agent is generally coated with moisture-proof paint, phenol varnishes and gasoline by varnish: gasoline = 1:3 (volume ratio) ratio of preparation, moisture-proof paint should be painted evenly, not Too thick.
Brushing primer is generally used 107 glue to prevent the treated wall from getting wet and improve the bonding ability with the wallpaper. The backing glue survives once, but there can be no omission.
Lines are the basis for ensuring that the wallpaper is pasted horizontally and vertically and the pattern is correct. When the vertical line is played, the wall with doors and windows is divided by standing. Without walls of windows and doors, you can pick a corner near the window sill and shoot a vertical line 50 mm from the width of the wallpaper. If you make a pattern and ask for a symmetrical pattern, you should pop out the centerline in the window and split the lines on both sides. If the window is not in the middle of the wall, in order to ensure that the sunken angle of the wall between the windows is symmetrical, it shall be divided at the centre of the wall surface and divided by the sides of the centerline.
Cut the wallpaper, you should accurately measure the height of the wall to the skirting board, according to the requirements for leaving 30-50 mm, cut the wallpaper. Patterned wallpapers, especially large-patterned wallpapers, should start with the graphics from the upper part of the wall. There must be someone responsible for the overall planning, careful cutting, and numbering should be done. Put it out, prohibit erection.
Different wallpapers, different ways of running paper. Plastic wallpaper should be immersed in clear water for 3 minutes before use, remove and shake off the floating water, put it aside for about half an hour, or use suffocating water. After the paper is evenly brushed with water, keep it for 15 minutes. , can also achieve the purpose. Glass fiber substrate wallpaper, wall covering, etc., no water stretching, no need to run paper. Composite wallpaper and textile fiber wallpaper should not be boring, use a wet cloth before the back of the paper can be brushed, if you do not understand the water swelling of the wallpaper, you can first cut a small strip, soaked in water after the test, observation Use it after shrinking changes.
Walls are generally not glued, but thicker wallpapers should be glued. Wall glue brush should be thin and uniform, brush or roller brush can be used, but no leakage brush, in addition to the brush at the female corner two times, the rest brush again. Paper back glue is mainly used when the ceiling is covered. The glue should be even, not wrapped, and not piled. After the wallpaper has been brushed, the paper is stacked on the back.
Paper paste wallpaper should be in accordance with the first horizontal surface after the horizontal plane, the first detail after the big surface, the principle of first up and down. There are wallpapers for the mosaic, and you should grasp the principle of vertical and afterwards. In the horizontal plane, it is high and low first, from the vertical line of the wall surface to the closing of the female corner.
The emphasis is on patchwork stitching, generally using overlap stitching method, the two sides of the wallpaper on the flowers overlap 20 mm, in the overlap with a wallpaper knife cut from top to bottom, clear after the scraping, the operation method shown in Figure 4-11 As shown. Particular attention should be paid when applying joints. Use one knife to cut two layers of wallpaper. Don't leave frizz. You can't cut through the walls. Foaming wallpapers and composite wallpapers can't be scraped with a scraper. You can use a towel or a brush to press.
The yin and yang corners should not be patched and should be overlapped. The width of the wallpaper around the corner should be greater than 12 mm. When wall papers are removed as much as possible when they are being smashed, it is not easy to remove them. The stencil can be cut using the center cross cutting method.
3, wallpaper paste acceptance wallpaper paste wallpaper and adhesives and other auxiliary materials of the variety, level, color, specifications should meet the design requirements. The surface treatment of the primary layer meets the standard, the surface color of the paste is consistent, no stain, no glue mark. Each piece is spliced, horizontal and vertical, the pattern is correct, and the patterns and patterns of the joints are matched. Visual observation at 1.5 meters without seams. There is no seam at the corner of the sun. The wallpaper is solid, without empty drums, alice, skirt wrinkles and other quality defects, the surface is smooth and clean.
4, wallpaper paste common quality problems and processing methods wallpaper paste common quality problems are two categories, one is the grassroots improper handling, one is the error in the paper construction. The quality problems that occur when the foundation is not handled properly are: PuTTY ripping, cracking, blemishes, bottoming, biting, etc. During construction, attention should be paid to the viscosity of putty, and appropriate amount of glue can be added. For holes, bumps, and ash deposits, it is necessary to apply a layer of glue on the surface. After the antirust paint is applied on the exposed iron parts, use white paint. Covering the grass-roots level and causing quality problems should be reworked and re-constructed as required by the standard.
The common quality problems in the construction of paste are: dead skirts, Alice, falling off, bubbles, detachment or loss of paper, and the surface is not clean.
The dead skirt is the most influential defect of the paste effect. The reason is that, besides the poor quality of the wallpaper, it is mainly due to the fact that when the skirt wrinkles are not smooth, they are squeezing and flattening. In the construction process, the wallpaper must be flattened before it can be crushed, and skirt creases must occur. After the wallpaper has been lifted, it must be slowly pushed up until it disappears. If there is a dead skirt, the wallpaper can be lifted and reattached when it is dry. If it is dry, then the wallpaper is scummed. After the grass-roots layer is processed, re-stitching is an important defect that affects the effect of the paste. The main reasons are that the base layer is not clean and the adhesive viscosity is poor. At the angle of the sun, such as throwing seams. In the construction process, after the grass-roots level processing and inspection is passed, the wall-papering process shall begin. The wallpapers of different materials shall use adhesives that are matched with them. The wallpaper shall be wrapped over an angle of more than 20 mm. Such as Alice flipped, according to the reasons for the rework, local grassroots improperly handled, re-cleaning the grassroots, fill the adhesive adhesive brush, such as glue viscosity is small, can replace the sticky adhesive, a larger range of Alice, It should be distributed and re-confused.
The main reason for the bubbles is uneven brushing of the glue, and the bubbles are not ejected when the paste is used. During the construction, to prevent the part of the glue from leaking, you can scrape it with a scraper after brushing to ensure even brushing. After scraping, scrape from the inside out with a squeegee to drive out bubbles and excess glue. If bubbles are found during use, a knife can be used to cut through the wallpaper. After the air is released, the glue can be used to clean the surface. The syringe can also be used to pump out the air. After the glue is injected, it can be flattened.
The main reason for wallpaper missing or missing is that the size of the paper is not measured accurately, and the paper is not vertical. In the construction, the actual size of the wall should be verified repeatedly, leaving a margin of 10-30 mm when cutting. When squeezing the adhesive, the seam must be pressed outwards from the patchwork and must not be slanted or pushed from the middle to the center. After 2-3 sheets are attached, the verticality is checked at the seam using a hammer. Timely correction. The occurrence of micro-breaking or loss of paper, the same color emulsion paint can be used to fill or use the same paper recommended to make up, such as from the seam or loss of more serious paper, you should tear off the weight.
Unclean surfaces are mainly caused by contamination of the glue in construction. Therefore, during construction, the operator should have a clean towel, wipe the excess glue at any time, and clean the hands and tools. If glue contamination occurs, wipe with a cleaner.
