4, the laying of moisture barrier membrane isolation film can delay the moisture absorption of the floor in the short term expansion. Each moisture-proof film should be about 5 cm overlap, and sealed with a bandage paper. In the wall around the isolation layer should also grow 5-10 cm, up curl. 5, wood floor can usually be arranged in accordance with the vertical alignment of the room or along the light, the use of rules or irregularities in two ways. The laying of rules is very neat, but the loss is large; irregular laying, the length of the floor is not limited, less loss. The floor must be pre drilled, the floor must be nailed to the floor, and wood keel phase. If the wood floor and keel, ground nail or nails in the small amount is not strong, will cause the hollowing. Every install board, application of foot, if the sound should be reworked. Laying should also be based on different materials, moisture content, and so on, to grasp the reasonable splicing gap, and set aside a reasonable expansion of space around. Note that between the plank joints shall not be more than 0.3 mm, bianju wall panels should allow the appropriate ventilation slot. Also note: construction is best to maintain the indoor temperature and humidity stability, should avoid working in heavy rain, rain and other weather conditions; the same room should be disposable wooden floor laying is completed; glue installation should be promptly wiped out.
2, leveling the ground floor, the floor must be flat. If the local potholes are very powerful, should be leveling. Gypsum binder can be used to add 30% of the sand, add water and stir into a paste, quickly smooth. Attention should be consolidated for more than 24 hours, in order to ensure that the ground dry, and then to lay wooden keel, so as not to damp wood floors. 3, set up a wooden frame wooden keel, must be crossed, positioning. Its spacing to 30-40 cm is appropriate. Such as too wide, step up to tremble; is too narrow, it will make the wood floor is very hard, lack of flexibility. Wooden keel should be used pine, fir and other deformation is not easy, holding a strong force of wood, with expansion screws fixed on the cement floor. The moisture content must be controlled within 18%. Wood keel, skirting the back should be moisture-proof treatment. The wooden keel should be fixed and firm, the surface to be smooth, so as not to affect the installation of the floor. Use level ruler to keel surface level, if not, should be adjusted. The wooden keel should be used for ventilation. If the above requires the laying of multilayer board or Blockboard and other auxiliary plate, each plate should be evenly divided into several blocks, fixed on wooden keel, and maintains a gap of 3-5 mm, and then walk a few steps, to see whether there is a sound.
Therefore, the focus here on the empty shop wood flooring products. 1, ready to go all the wood floors to the construction and installation of the site, should be opened in a room for more than a week, so that the wood floor and room temperature, humidity, to avoid future deformation. Before installation should be selected, remove the obvious quality defects. Placed in the same room as the color, pattern, and thickness of the same room; with a slight quality defect but no influence on the use of the bed. 2, leveling the ground floor, the floor must be flat. If the local potholes are very powerful, should be leveling. Gypsum binder can be used to add 30% of the sand, add water and stir into a paste, quickly smooth
