Chengdu PVC plastic flooring

Ground detection and treatment is one of the laying of resilient flooring the most important part, the ground kind of complicated, must be handled with caution. All the grassroots must be clean, dry and clear all will affect the bonding effect of the substance, there is no structural defects. (1) Before installing the ground must be kept clean, remove dust, paint, glue, and other residue. (2) the use of CCM rule measure ground moisture content, moisture content can be less than 4% of construction, the moisture content of between 4% -8% of ethylene need brushing interface agent on the back cover, moisture content of more than 8% or more must be waterproof layer construction . (3) a thorough cleaning floors, use more than 1500W grinding machine with diamond grinding head stuck in the ground cover small particles and laitance clear. First, the self-leveling construction - rendering 1, the absorbent grassroots such as concrete, cement mortar layer should be multi-use interface treatment agent according to 1: 1 ratio for blocking primer diluted with water. 2, grass-roots non-absorbent such as tiles, terrazzo, marble, etc., we recommend using dense rendering interface treatment agent. 3, such as the moisture content is too high (> 3%) and the need for immediate construction, epoxy interface treatment agent may be bottoming process, but only if the moisture content should not exceed 8 percent. 4, the interface treatment agent construction should be uniform, no obvious effusion. After the interfacial surface treatment agent to dry, self-leveling construction can be carried out the next step. Second, the self-leveling construction - stirring 1, a packet of self-leveling cement ratio in accordance with the provisions of Shengyou Qing into the mixing bucket of water, while stirring dumping. 2, in order to ensure self-leveling stir, to use high-power, low-speed electric drill with a special stirrer. 3 and stir until no lumps of homogeneous slurry, which was allowed to stand for aging for about 3 minutes, stirring once again briefly. 4. The amount of water should be strictly in accordance with the water-cement ratio (see corresponding leveling instructions). Too little water will affect liquidity. Excessive strength after curing is reduced. Third, self-leveling construction - laying of the stirred slurry was poured self-leveling in the construction of aerodromes, it will own flow and leveling the ground, if the design thickness ≤ mm, you need a little help of the special tooth scraper Scraping. 2, followed by the construction workers should be allowed to wear special cleats into the construction ground, with a special self-leveling deflated self-leveling surface in gently rolling drum, stirring mixed in the air release, to avoid air bubbles pockmarked face and interface elevation. 3, please closed immediately after completion of construction site, is prohibited within five hours walk, within 10 hours to avoid heavy impact 24 hours after laying PVC floors. 4, winter construction, laying of the floor after leveling construction should be completely dry. 5. For fine grinding polishing of self-leveling, self-leveling appropriate after drying. Fourth, the pre-shop and Cutter 1, the environmental impact of construction by the construction quality, the ideal temperature is about 20 degrees, 24 hours in advance before construction, the product in the construction and glue into place. 2, using a dedicated edger cutting edge of web cleaning. 3, the sheet laying, should be close and no seam between two materials. 4, the web laying, lap two volumes of materials cut by overlap method generally requires overlapping 3cm. Keep the knife cut. 5, in the same area as far as possible using the same batch of product. 6, playing the line: according to design requirements elastic line, cell and positioning, pay-principle using two-point line elastic line shall visually, estimation methods. 7, Conference materials: arranged according to the room shape and layout designs materials, parquet do first, do full shop, the first sophisticated, simple post. V. paste 1, choose the appropriate class of floor glue and scrape board according to the manufacturer's guidelines. Such as: the glue evenly with A2 or A3 scraper blade on an absorbent base layer, select the appropriate glue to dry according to the environmental conditions of the time, about 10 minutes. When the glue by a sallow becomes translucent (non-stick means is appropriate), to paste. 2, when the Stones roll, roll one end of the folded sheet, first clean the floor and roll on the back, then scraping gum above the ground floor. 3, paving the sheet, the sheet is turned up from the middle to the ends, the same will be back on the ground and the rear floor cleaning glue. 4, different adhesives in the construction requirements will vary, please refer to the relevant product specifications for construction.
