1), base surface treatment:

Leveling, cleaning (the base surface is free of sundries and dirty oil), and the base surface is wet. The pipe root, floor drain, drain, yin-yang angle and other parts prone to leakage that protrude from the ground and wall surface should be treated first.

2) stir:

First, pour 2/3 of the liquid material into the container, then slowly add the powder and stir for 3-5 minutes at the same time, then continue to pour the remaining 1/3 of the liquid material, and fully stir until a uniform slurry without powder lumps and particles is formed (it is best to use a stirrer);

3), brushing:

Brush directly on the base surface with a brush or roller brush, and use the force evenly, without brush leakage; Generally, it needs to be painted twice (depending on the use requirements), and the thickness of each painting shall not exceed1mm; After the previous one is slightly dry, the next one shall be painted (just not sticky, usually with an interval of 1-2 hours), and the front and rear vertical cross painting shall be conducted, with a total thickness of1-2 mm; If the coating is cured, wet it with water before painting another layer.

4), maintenance and protection:

After 24 hours of construction, it is recommended to cover the coating with wet cloth or spray water to maintain the coating. Please take protection against trampling, rain, sun exposure, sharp injury, etc. before completely drying after construction.

5), check (closed water test):

After the waterproof coating is cured, there should be no blistering, hollowing, buckling, tire exposure, peeling, etc. Toilets, pools and other parts should be filled with water for 48 hours after the waterproof layer is dried (at least 24 hours in summer and at least 48 hours in winter) to check whether the waterproof construction is qualified. Lightweight walls need to be drenched with water.

Precautions:

Three-point materials and seven-point construction are generally recognized in the waterproof industry, which fully reflects the importance of waterproof construction. If the construction is improper, even the best materials will leak.

1), base surface treatment is the foundation.

The treatment of base surface is the key to waterproof construction. Before construction, the base surface must be cleaned to ensure that it is firm, flat and clean, free of dust, greasy, wax, release agent and other debris. If there are defects such as pores and cracks, it 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.

2), besmear brushs method should pay attention to

When brushing evenly, be careful not to miss the brush; Keep the angle of vertical intersection when painting twice before and after, so as to fully cover in place; Single brushing should not be too thick, especially at the nozzle and corner, which should not exceed 1mm to prevent cracks after drying, and flexible waterproof coating should be selected for nozzle and corner. The shower area shall be painted180cm or the ceiling height, and other walls shall be painted 30cm high.

3) Maintenance and protection are also important.

After 24 hours of construction, it is suggested to cover the coating with wet cloth or spray water to maintain it. Treading, rain, exposure and sharp damage must be prohibited before it is completely dry, especially when installing sanitary ware in the later stage, special attention should be paid not to destroy the waterproof layer.

4), carefully check to prevent future trouble.

Be careful when painting, and check carefully after painting, especially at joints, yin and yang angles, nozzle and other parts; After the completion of the construction, the closed water test shall be carried out for 48 hours, and the closed water height shall be increased as much as possible, not less than 20cm. Carefully check whether there are traces of water seepage or water drops on the ceiling downstairs. The light wall shall be subjected to water spraying test, and the back wall shall be inspected.

5), pay special attention to

Waterproof slurry is suitable for use at 5℃-40℃ to avoid high temperature, low temperature and outdoor rainy weather;

The prepared mixture must be used up in about 1 hour;

It is forbidden to add water to the condensed waterproof slurry; Please keep ventilation after waterproof construction to make the waterproof layer dry;

Prohibit pure cement paste when sticking bricks on the waterproof layer, and construct according to the requirements of tile construction; It is recommended to use mortar glue;

Newly poured concrete should be dried before waterproof construction;

Skin contact should be avoided during construction. If it is careless, it should be washed with clear water in time, and eye contact should be treated promptly.
