1. The Installation Technology

1.1 Floor Examination

1.1.1. Temperature hygrometer were used to detect temperature and humidity, indoor temperature and surface temperature at 15 ℃ advisable, should not be below 5 ℃ and 30 ℃ above construction. The relative air humidity for construction should be between 20% and 75%.

1.1.2 The water content of the primary area should be measured by the water content tester, which should be less than 3%.

1.1.3 The strength of the base should not be lower than the requirement of the concrete strength c-20, otherwise suitable self-leveling will be adopted to strengthen the strength.

1.1.4 The test results of the hardness tester should be the surface hardness no less than 1.2 MBPS.

1.1.5 For the construction of the PVC flooring, base not flatness should be within 2 meters ruler fall of on any account is less than 2 mm, otherwise should adopt suitable self-leveling leveling.
1.1.6 Self-leveling be on probation before the surface should be smooth, dry, solid, no dust and grime, free tile ground drum, should the vacuum summoned the layer of the ground to kick off. Remend the ground.

1.2. Ground level pretreatment

1.2.1 The use of more than 1000 w floor polishing machine with appropriate grinding to whole floor polishing, remove paint, glue residue, such as convex and loose plot, free drum plot must also be removed.

1.2.2 Use an industrial vacuum cleaner less than 2, 000 watts to clean the floor.
1.2.3 For cracks on the ground floor, stainless steel reinforcement and polyurethane water-resistant adhesive surfaces are used to repair the cracks.

1.3.  Self-leveling construction -- bottom

1.3.1 The absorptive base such as concrete and cement slurry should be treated with a multi-purpose interface.

1.3.2 Non-absorbent grass roots such as ceramic tile, terrazzo, marble, etc., suggest the use of solid type interface to handle the base.
1.3.3 Such as the moisture content is too high (> 3%) at the grass-roots level and instant construction, epoxy interface treatment agent can be used to render processing, but the premise is the moisture content should not be greater than 8%.

1.3.4 The construction of interface treating agent should be uniform, no clear liquid. After the surface drying of the surface treatment agent, the next stage of self-leveling is done.

1.5.4 Construction in Winter, the laying of the floor should be done after 48 hours in the construction of self-leveling.
1.5.5 If it is needed to polish the self-flowing flat, it should be done after the self-leveling and drying.

1.6. The shop of the floor - cut

1.6.1 Whether it is a coil or block, it should be placed on the spot for more than 24 hours, making the material memory return and the temperature is consistent with the construction site.

1.6.2 Use special trimmings to cut and clean the edges of the coil.

1.6.3 When the block is laid, there should be no seam between the two pieces of material.

1.6.4 When the coil is laid, the overlap of the two materials should be overlapped, which usually requires the overlap of three centimeters. Be careful to keep one knife cut.

1.7. The shop of the floor -- pasted

1.7.1 Select suitable glue and scraping plate suitable for PVC floor.
1.7.2 Roll up the end of the coil when it is spread. Clean the ground and the back of the paper first and then scrape it over the ground.

1.7.3 When the block is spread, please turn the block from the middle to the side, and then the back of the floor and the back of the floor.
1.7.4 The different stick mixture will be different in the construction, please refer to the corresponding product specification for the construction.

1.8. The pavement of the floor -- exhaust

1.8.1 After the floor is pasted, first use the cork to push the surface of the floor to smooth and extrude air.
1.8.2 Then roll the floor with 50 or 75 kg of steel, and make up the splicing in time.
1.8.3 The excess glue on the floor surface should be erased in time.
1.8.4 After 24 hours, the grooves and welds will be carried out.

1.9. The pavement of the floor -- open seam

1.9.1 The slot must be made after the glue is completely solidified. Use the special grooves to open the groove along the seam, to make the welding firm and open seam not to be transparent, and suggest that the groove depth is 2/3 of the thickness of the floor.
1.9.2 At the end of the opening, please open the seam with the same depth and width.
1.9.3 Before the weld, the dust and debris left in the slot shall be removed.

1.10. The pavement of the floor -- the weld

1.10.1 A manual welder or automatic welding machine can be used for welding.
