Precautions for waterproof and leak-proof in toilet:
1, brush method should pay attention to the uniform force when brushing, and be careful not to miss the brush; When painting twice before and after, keep the angle of vertical intersection, so as to fully cover in place; Single-layer coating should not be too thick, especially at the nozzle and corner, and should not exceed 1mm to prevent cracking after drying. Flexible waterproof coating should be used for nozzle and corner. Brush the shower area 180cm or ceiling height, and brush other walls with a height of 30cm.
2. Base surface treatment is the key to base surface treatment and waterproof construction. Before construction, the surface of the base must be cleaned to ensure that it is firm, flat and clean, free of dust, oil, wax, mold release agent and other sundries. If there are defects such as pores and cracks, they must be repaired and smoothed with cement mortar in advance, and the corners of yin and yang should be painted into circular arcs. Keep the base surface moist but free of Mingshui.
3. Waterproof slurry is suitable for use at 5℃-40℃, avoiding high temperature, low temperature and outdoor rainy days; The prepared mixture must be used in about 65438 0 hours; It is forbidden to add water to the condensed waterproof slurry;
Please keep ventilation after waterproof construction to make the waterproof layer dry; Pure cement slurry is prohibited when the waterproof layer is plastered with bricks, and construction shall be carried out according to the requirements of tile construction; It is recommended to use tile glue; Fresh concrete should be dried before waterproof construction; Skin contact should be avoided during construction.
