1. Before the construction of plastic wood flooring, it is necessary to ensure that the concrete base ground of the construction site is flat. This is very important. I hope everyone does not force construction to save time, otherwise the consequences will be more than worth the loss.

2. The middle distance of the keel should be controlled between 310-410mm, and a gap of about 10mm should be left between the butt joints of the keel ends to facilitate drainage. At the same time, the end joints between the keel rows should be staggered and not in a straight line. The allowable error of keel spacing is<10mm, the flatness is<3mm, and the expansion joint between keel and wall is 8-10mm.

3. When the construction site has poor basic ground construction conditions and cannot achieve proper structural stability, it is necessary to replace the wooden plastic keel with steel keel. The previously used galvanized steel should be used, and the welded joints should be treated with rust prevention after removing welding slag.

4. The size of the floor splicing gap should be reasonably determined based on the temperature and humidity of the environment during the installation of the wood plastic floor, the length of the floor, the moisture content of the floor, and the specific situation of the laying area.
