Surface parquet wood surface construction cement grassroots should be smooth, hard, dry and free of grease and other impurities, moisture content should not exceed 9%. When the grass roots from the sand surface pockmarked face, cracks phenomenon, should be brushing (Scraping) emulsion putty processing, each time brushing putty thickness should not exceed 0.8 mm, dried and polished with a 0-iron emery cloth, apply Brush putty second time until after the smooth surface, and then diluted with water emulsion brushing again. Flatness of the surface of the substrate, using a ruler to check 2m gap should not exceed the allowable 2mm. In order to ensure quality assurance and paste wood in Sichuan, the primary surface can be pre-brushing a thin uniform adhesive base. Preparation of gum base: when using water-soluble adhesive, glue should add water according to the same; when using a non-water-soluble adhesive, glue should be added according to the same weight of 10% gasoline (65) and 10% ethyl acetate (or acetic acid ethyl) and stir well. Floorboards before the Stones should be designed mosaics and size requirements for line test bomb shop, and check the level of patchwork and sewing, etc., numbered to meet the requirements. Construction, should be self-center to the surrounding room in numerical order to start paving. Adhesives can be polyurethane rubber, epoxy glue, polyvinyl acetate emulsion adhesive 4115, 8123 PVC adhesive, YJ-1 polymer construction adhesive, glue and various multi-purpose building 926 all-purpose adhesive and so on. When brushing the adhesive surface of base Sichuan wood factory, plastic varieties should use the appropriate method. When using emulsion adhesives Sichuan wood flooring, adhesives should be separately painted surface and ground plate on the back of the grassroots; when using solvent-based adhesives, should be uniform coating on the substrate surface. Coating thickness of the base plate surface and the back should not be greater than 1 rnm; After the glue should stand 10--20min, then wait while paving sticky glue or adhesive products according to the specific requirements of the operation; and should be in place to accurately and paste dense. The gap between the plates parquet wood surface layer should not exceed 0.3rrllTl. Should stay out of the surface layer between the wood floor and wall 10--201mm gap, the gap cover with wooden skirting boards. Color PVC sheet flooring 1. Product specifications (1) Width (format width): 2000 mm; (2) Thickness: 1.5 ~ 3.5 mm; (3) per roll length: 20 133 (40 m2) or 30 rn (60 m2). Such as size specifications have special requirements, agreed upon by both parties. 2. Storage and transport of the product during transportation and storage, should be stacked upright way, or set aside for the use of the inner core of the way through the bracket to avoid foam plastic layer stack caused by prolonged pressure and loss of elasticity. Should be stored indoors, avoid direct sunlight and pay attention to ventilation Sichuan wood manufacturers, room temperature should not be higher than 50 ℃. 3. Construction Points (1) primary requirements: indoor ground floor in the dry grass roots should be smooth, clean and free of sand and other lobes. (2) the laying of approach: Depending on the requirements, you can choose a fixed tiling adhesive type, temporarily fixed laying ceremony, and the activities of the different approaches, such as floating laying ceremony. ① adhesive fixing Stones - For long-term requirements for ground Stones roll, can be painted over adhesive bonding methods. ② temporarily fixed laying ceremony - For the relocation plan to roll laying on the ground, can be double-sided tape on the back of the four sides of the membrane attached to the grass roots, pay attention to prevent Qiaojiao Alice and other conditions. ③ Activities floating shop style - less space for indoor floor, also without any adhesive fixing, furnishings, etc. can be used to suppress the web site of the corner, can play the same membrane using specialty and decorative effect. (3) stitching web: Ground floor rooms are often greater than the width of the web width, the need to widen the web splicing. When stitching, you must pay attention to the design patterns for the entire fight together; splices using flooring adhesives bond firm, or with double-sided tape to bridge joints, and with the primary cement.
