1. Correct: U.S. nails are important auxiliary materials for fixing keels. We must use stainless steel nails that are waterproof and rust proof. This will not rust for a long time. Wrong: An irresponsible company cut corners and used nails. Although the nails can also hold the keel, it will take a long time to rust, the keel will loosen, and of course the floor will buzz. 2, correct: keel buried under the floor easily damp, so the keel wood must be better. The keel is the best choice for larch timber, after drying, degreasing, anti-corrosion treatment, to avoid keel moisture, corrosion, thus ensuring the quality of the floor. Wrong: This is the wood keel used by the guerrillas of the road. The ordinary wood has been treated with moisture without any treatment, and there are large holes in the fixed place. The keel is prone to moisture fracture for a long time and directly affects the quality of the floor. 3. Correct: There will be some joints in the keel of a room. At the junction of the wooden keel, the keel joint is at an angle of 45 degrees and the connection is more stable. Mistake: Sloppy companies do not connect the keel to save trouble. The keel is difficult to fix in a straight line. It will be easy to loosen after a long time. 4. Correct: There are only one nail in each fixed position of the mounting keel, and the nail is very firm and smooth without any looseness. Wrong: The irresponsible company used two nails at the keel fixation. Although firm, it made the keel crack. 5. Correct: Use impact drill to drill on the keel. The drill bit must pass through the keel and the studs. Avoid keel and loose wood when drilling. Error: The unevenness of the keel is also a factor that causes the floor to rattle. Some road guerrillas do not pad small blocks at all. How can the keel be flat? 6, correct: There are pipes in the corner, the dragon skeleton is in the pipeline, but does not squeeze the pipeline. The keel can both protect the pipeline and ensure that the floor is flat and free from loosening. Wrong: In the place where there is a pipe line, the plan is to simply stop here and the keel is too far away from the corner so that the floor can not fall? 7. Correct: After the workers install the keel, they must clean the site quickly and keep the keel clean and dry. Error: This site is not only dirty, but also dirty with keels. It is also easy to provoke ants. Del floor nature floor room stainless steel decor
