Multi-layer composite floor installation method

Directly applied (for geothermal and non-geothermic): Moisture-proof cloth floor is suitable for the floor of plus or minus 2mm height difference.
installation steps:
(1) On the refurbished ground, firstly lay a damp-proof cloth to cover the entire ground in order to achieve a moisture-proof sound insulation and balance production effect. The cushion material used for geothermal should not be too thick to facilitate heat conduction.
(2) Spread multi-layer solid wood flooring on moisture-proof cloth.


Straight-laid (non-geothermic): plywood damp-proof floor
1. Applicable scope: It is applicable to the ground with the flatness of no more than 5mm and the second floor above.
2, installation steps:
(1) To clean the floor, the splint should be cut to a size of not more than 600×600 mm, and a gap of 5 to 10 mm should be reserved between the splint and the splint.
(2) Laying damp-proof or flame-retardant foam on the plywood, the wall-side damp-proof cloth should be more than the ground 8-10MM, and do not stick between the plywood and the moisture-proof cloth.
(3) Lay the floor on the moisture-proof cloth, and do not stick it between the floor and the moisture-proof cloth, and nail it into the fixed floor with a 45-degree angle on the male nail.


Elevated type (applicable to non-geotherm type): Special wood keel thick plywood moisture-proof cloth floor
1. Applicable scope: It is applicable to the ground with the flatness of no more than 5mm and the second floor above.
2, installation steps:
(1) A special wooden keel is prepared. The spacing between wooden keels is less than or equal to 350 mm, and the plane must be flat.
(2) Apply a water-resistant adhesive to the wooden keel. Lay the plywood with a thickness of about 12 mm on the skeleton. The plywood should be cut to a size no larger than 600×600 mm. The spacing between the splint and the splint should be 5 to 10 mm. Use an air gun to drive the headless nail into the splint and the frame.
(3) Spread a damp-proof cloth on the plywood, lay the floor on the damp-proof cloth, and nail it into the fixed floor with a headless nail at an angle of 45 degrees.
