A, ground level ground test

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. For the construction of relative humidity of the air should be between 20% to 75%.

2, the moisture content tester were used to detect the moisture content of grassroots, grassroots moisture content should be less than 3%.

3, the strength of the grass-roots should not be lower than the requirement of concrete strength C - 20, otherwise should adopt suitable self-leveling to enhance strength.

4, hardness tester is used to inspect the result should be a basic surface hardness of not less than 1.2 million mpa.

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.

Second, the ground level ground preprocessing

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.

2, with no less than 2000 watts of industrial vacuum cleaner dust collection was carried out on the floor clean.

3, for the crack in the floor, can use stainless steel reinforcement and polyurethane waterproof adhesive surface of quartz sand to repair.

Three, the pavement of the floor - before paving and cut

1, whether coil or piece of material, should be 24 hours to the scene, make the material memory reduction, temperature in accordance with the construction site.

2, use special trimming device for coil cutting burrs of cleaning.

3, tile laying, should be close to and no joint between two pieces of material.

4, coil laid, two pieces of material set it should use overlapping cutting, usually require overlapping 3 cm. Keep a knife to cut.

Four, the pavement of the floor - paste

1, choose suitable for PVC
