1, ground basic requirements The yin and yang angles between the wall and the ground are 90°, and the yin and yang angles are straight and flat. The ground should be smoothed and the error should be less than 2mm 2m 2 . 2, ground grinding Before construction, it is necessary to check whether the ground is shelled, protruded or recessed into the ground, or cracks. If this phenomenon occurs, it must be repaired and polished. The foundation of the ground should be level and the humidity must be greater than 40%. 3, the basic grinding Pay attention to the ground conditions while polishing, and where the polishing time is longer, and the grinding time in those places should be as good as possible. Ground dust and other debris that is attached to the ground should be ground. Then sweep the floor with a broom and inspect the grinding results to see where the ground still needs to be polished. 4, bottom oil processing Before vacuuming, use a vacuum cleaner to clean the floor, leaving no dust. If it is a cement floor, the bottom oil can be watered in a ratio of 1:1, while marble and water milled ground are not watered. When the base oil is to be evenly painted, do not miss the paint. Brush it horizontally and horizontally. The foundation of the ground should not be painted once more. Only 1-2 hours after the base oil can be self-leveling. 5, self-leveling construction According to ground conditions Flooring Marble Cement
