(1) The floor should be laid in the later stage of construction and should not be cross-constructed. It should be sanded and painted as soon as possible after laying. So as not to soil the floor or deform the moisture. (2) Before laying the floor, it is advisable to unpack and stack it on the paving site for 1-2 days to adapt it to the environment, so as to avoid expansion and contraction after laying. (3) The paving should be well protected against moisture, especially in the case of wet conditions such as the bottom layer. Moisture-proof measures include applying moisture-proof paint, paving moisture-proof film, using padding treasure, and so on. (4) The keel should be flat and firm, and should not be reinforced with cement. It is best to use expansion bolts and US nails. (5) The keel should be made of larch and Liuan with strong nail holding power. The moisture content of the keel or wool floor should be close to the moisture content of the floor. The keel spacing should not be too large, generally not more than 30 cm. The ends of the floor should be placed on the keel, and should not be left empty, and nails must be nailed on each keel. Do not use water based glue. (6) The floor should not be laid too tightly. There should be enough expansion joints (0.5~1.2 cm) around it, and it should not be over-widely laid. If it is wider, it should be separated and cut, and then the copper strips should be transitioned. (7) Floors and halls, toilets, kitchen rooms, etc. should be thoroughly isolated and protected from moisture. (8) The chromatic aberration of the floor is inevitable. If there is a high requirement for chromatic aberration, it can be pre-sorted and adopt a gradual transition method to reduce the visual abrupt change. (9) Avoid flushing with water during use, avoid long-term sun exposure, continuous air blow of air conditioner, prevent rain forest at the window, and avoid hard objects from rubbing. To protect the floor, wax can be applied to the painted surface (from the perspective of protecting the floor, waxing is better than painting).
