1. Use the moisture content tester to measure the moisture content of the base layer, and the moisture content of the base layer should be less than 3%.
2. The strength of the grass-roots level should not be lower than the requirement for concrete strength C-20, otherwise proper self-leveling should be used to strengthen the strength.
3. The test result with a hardness tester should be that the surface hardness of the base layer is not less than 1.2 MPa.
4. For the construction of badminton flooring materials, the unevenness of the grass-roots level shall be within 2 meters of the ruler and the height difference should be less than 2 millimeters. The surface shall have no wheel marks, cracks, rotten edges, etc. Otherwise, according to the ground conditions, do the appropriate ground treatment.
Flooring - Pre-paving and cutting pre-paving: Clean the floor before prefabricating the floor, and then lay OS Euclidean rubber floor tile for more than 2 hours to restore the material's memory and make the material better. Fits with the ground.
Cutting: Use a special edger to cut the raw edges of the coil.
Note: When the floor is pre-paved, the overlap between the two pieces of material should be fully aligned and the gap should be controlled within 1mm.
Pavement of the floor - paste Choose OS Euclidean rubber special PVC tape. When sticking, both sides of the two pieces of plastic are rolled up. Then stick the PVC tape on the clean floor. Before the ground glue is fixed on the tape on the ground, once again, the overlapping parts of the two materials should be fully aligned, the gap is controlled within 1mm, and then the tape protective film is torn off from the bottom of the ground glue.
Slot The depth of the slot should be controlled properly. The purpose of our slotting is to weld two floors together. It is only the wear-resistant layer of the floor that can be welded together, so the depth of the groove must be controlled just beyond the wear-resistant layer.
Welding Using a special welding gun, the welding wire is glued together with the ground glue. After welding, there will be a protruding electrode at the joint. A special blade will be needed to make it flat.
