Waterproofing works in the bathroom renovation process, the bathroom, the kitchen is an important part of the entire renovation project is directly related to the comfort level of the home to live after, so be sure to pay attention to.

1, the acceptance of the grassroots, the requirements are as follows:

Whitewashed walls with waterproof mortar stucco, to ensure that paint the flat, smooth, compacted, can not afford the sand, not hollowing;

Ground leveling, leveling layer slope to drain port, and to ensure the smooth, smooth, compacted, can not afford to sand, not hollowing meet decoration design requirements ensure that the elevation of the leveling layer;

The bathroom floor overcast angle at the pan of water have to do 20-50 ㎜ steel retaining angle, angle of 45 °, height room elevation prevail;

Were built toilet threshold retaining waterproofing mortar construction of permanent threshold retaining line, size 20 * 180 * 780 mm (height of not less than 20 mm, whichever room elevation);

2, grassroots clean-up, sweeping to no dust, clean, and fully pre-wet grass-roots, keep moist without Mingshui state;

3, node processing:

Pipe root process: JS waterproof coating brushing twice capillary crystalline material, then Flexibility material brushing twice ≧ 2.0 mm thick;

Wall the ground hole filling: water did not leak repair all holes in walls and floors, where necessary using polyethylene fiber waterproofing paste fill flat;

Kok Yin Pan-water treatment: polyethylene fiber polymer the waterproofing membrane cold Nianman Shop Act wrapping angle processing, material selection is not less than 400 g / m, a width of not less than 300 mm;

4, the start of the large area waterproof construction:

Waterproof wall: brushing method is elevation ≧ 2000 mm, material selection, JS waterproof coating capillary crystalline material, at least two coated ≧ 1.5 mm thick, criss-cross brushing, to ensure that the brush is not missed, not dew point, no pinhole;

Ground water: brushing method operation, material selection, JS waterproof coating penetration of crystalline materials and flexible materials, twelve selection penetration type, the third choice of flexible type ≧ 2.0 mm thick, criss-cross brushing to ensure that no leakage brush, dew point, no pinholes, overall smoothness and uniformity;

5, sealing water test:

Filled with water to not less than 5 cm, less than 48 hours, to ensure no leakage, no wet stains;

6, finished the conservation and protection of:

According to weather conditions, the waterproof layer curing water conservation, walls, floors conservation of not less than 2 times, product protection to ensure that not stampede, as little as possible when installed stone nail before curing.

Note:

The product powder should be stored in a dry place, the liquid material shall be kept in the shade temperature should be above 5 ° C, and configured the paint should be used up in 3h;

Each face construction must be a process of construction is completed, after acceptance into the next process, can not be cross-operation.

Coating overlap lap must request that same layer coating has lap width of 50 mm, the construction joints lap width is greater than 100 mm, the upper and lower operating workers must pay attention to cooperate with each other.

After construction should be promptly cleaned of construction tools, so as not to dry and difficult to remove.

The tube root site to be protected, no collision damage displacement construction;

Coating should be completely dry for 2 days before the construction of the protective layer.
