Abstract: construction process steps of sportsPVC floor
 
1. the ground must be kept dry, dry and free of cracks. 2. the water content of the concrete ground must not exceed 3%. 3. keep the flatness of the ground: the difference between the ground surface of the ground surface and the range of 2m ruler is not more than 3mm.
4. the floor of sports wood, composite wood floor, tile, marble and the floor of marbles can be directly paved. First, floor detection 1, using temperature and humidity meter to detect temperature and humidity. Indoor temperature and surface temperature should be 15 degrees, not 5 and below 30 degrees. Relative air humidity should be suitable for construction
Between 20%-75%.
2. The moisture content of the base is detected by the water content tester, and the water content in the base should be less than 3%. 3, the strength of the base should not be lower than the requirement of the concrete strength C-20, otherwise the suitable self leveling should be adopted to strengthen the strength. 4, the hardness tester test results should be the surface hardness of the base is not less than 1.2 MPa.
5, for the construction of PVC flooring, the roughness of the base should be within the range of 2 meters, the difference between high and low is less than 2 mm, otherwise, the proper self leveling should be used for leveling. Two, floor 1, pretreatment with 1000 watts or more of the floor grinding grinding machine with the appropriate floor of the whole grinding, remove paint, glue and other residues
, bump and loose plots, empty plots must be removed. 2, use an industrial vacuum cleaner with no less than 2000 Watts to clean the ground. 3. For cracks on the floor, stainless steel reinforcement and polyurethane waterproof adhesive can be used to repair the surface of quartz sand. Three, self leveling construction - bottom 1, absorbent base such as concrete, cement mortar leveling layer should use multipurpose first
The interface treatment agent was diluted by 1:1 and diluted to the bottom. 2. The non absorbable base, such as tiles, terrazzo, marble, etc., suggest the use of dense interface treatment agent to carry out the bottoming. 3, if the base water content is too high (>3%) and need immediate construction, the epoxy interface treatment agent can be used for bottoming treatment, but the premise is that the moisture content of the base should not exceed 8%.
4, the construction of the interface treatment agent should be uniform, without obvious liquid accumulation. After the surface wind drying of the interface treatment agent, the next step of self leveling construction can be carried out. Four, self leveling construction - mixing 1, a package of self leveling in accordance with the specified water cement ratio into a mixing bucket with clean water, side dumped and stirred.
2. In order to ensure the uniform mixing of self leveling, the electric drill with high power and low speed must be used to mix with a special agitator. 3, stir to the non - lump uniform slurry, the static and mature for about 3 minutes, and then briefly stirring once.  4, the amount of water added should be strictly in accordance with the water cement ratio (please refer to the corresponding self leveling manual).
Too little water can affect liquidity. Too much will reduce the strength after curing. Five, self leveling construction - laying 1, self leveling slurry mixing well dumped in the floor construction, it will automatically flow and leveling the ground, if the design thickness is less than or equal to mm, it needs a special tooth scraper scraping. 2. The builder should be followed

Staff wear special spikes, enter the ground construction, with the self leveling roller for deflation in self leveling the surface gently rolling, mixing in the mixed air release, avoid bubble pits and interface height. 3, after the completion of the construction, please close the scene immediately, no walking within 5 hours, 10 hours to avoid the impact of heavy objects, 24 hours after the laying of PVC floor. 4, in winter construction, the floor should be laid for 48 hours after the construction of self leveling.  5, if the self leveling is required to be polished and polished, it should be carried out after 12 hours of self leveling construction. Six, the floor of the pavement - laying and cutting 1, both sports flooring is a material or bulk, should be placed in the field for more than 24 hours, the reduction of material memory, temperature consistent with the construction site. 2. Use a special trimming machine to cut and clean the edges of the material. 3, the bulk of laying, between two pieces of material should be close to and no seams. 4, when the rolling material is laid, overlapping cutting should be adopted for the lap of two pieces of material, which is generally required to overlap 3 centimeters. Pay attention to the cutting of a knife. Seven, floor 1, Beijing pavement - paste Nobel Ka select glue suitable PVC sports flooring and scraping plate. 2, tiles, one end of the coil will be folded up. First the Qing Ping sweep and roll back, then on the floor above frictioning. 3, block paving, please send the bulk from the middle to both sides turn up, also will be back after cleaning on the ground and floor glue. 4, different paste in the construction requirements will be different, specifically refer to the corresponding product instructions for construction. Eight. The paving of the moving floor - exhaust and rolling
1, after the floor is pasted, the floor surface is pushed and pressed with the soft wood block to smooth and squeeze out the air. 2, then use 50 or 75 kilograms of steel roller evenly roll the floor and timely repair the stitching edge of the edge of the situation. 3, the excess glue on the surface of the floor of the sports floor should be cleaned in time.
