Choose brands with good quality and good reputation, such as: Leibangshi, Degao, etc.

2. How to construct? Deal with the base surface (substrate) of the waterproof position. The base surface is treated into a firm, flat and clean surface, free of dust, greasy, wax and other debris substances; If there are pores, cracks and unequal defects on the base surface, it must be repaired and smoothed with cement mortar in advance, plastic strips are recommended to be pasted on the expansion joints, a layer of non-woven fabric must be added to the node, and the nozzle filling is recommended to use Leibangshi plugging king or nozzle grout; The corners of the wall should be plastered into an arc shape (or V-shaped); Make sure the base surface is sufficiently wet, but there is no open water;

Pay attention to the waterproofing to be in place. Use a brush or roller brush to apply directly to the base surface, and the strength is used evenly, and the brush should not be missed; Generally, it needs to be brushed twice (according to the requirements of use), and the thickness of each brush should not exceed 1mm; After the previous one is slightly dry, the next one is brushed (just non-sticky, generally at an interval of 1-2 hours), and the front and rear vertical cross brushing, the total thickness of the brush is generally 1-2mm; If the coating has already cured, moisten it with water first when applying another layer. Special attention should be paid to the corner part of the wall to be treated into an arc type and then painted, and the painting can not be too thick (the total thickness does not exceed 2); The pipe should be sleeved with a casing, and the holes of the casing and the wall should be filled with a plugging king, and the waterproof material should be brushed to the height of the casing 10 and not too thick;

3. What are the special precautions? Pay attention to the position and height of the waterproof applied. Ground; Generally, the wall is repainted and brushed 30 high; Paint the wall around the shower area 180 high or to the top of the wall; There is a bathtub where the upper brush is 30 higher than the bathtub.

Do a good water test. After the waterproof coating is painted to form a waterproof layer (about 24 hours later), the water storage is 20 high, and after 24 to 48 hours, see if the water is significantly reduced or go downstairs to see if there are wet water spots on the roof, and if not, it means that the waterproof construction is successful.
