Toilet waterproofing membrane construction

(1) Grassroots cleaning: first use a shovel and a broom and tools to remove the protrusions, mortar and pimples on the surface of the grassroots and clean up the dust and debris, and carefully clean up the yin and yang corners, pipe roots, floor drains and other parts.

2) Brush the waterproof layer on the bottom surface: A special person is responsible for weighing the materials and preparing them, weighing the liquid, powder and water used in the ingredients according to the mix ratio provided in the above table, and stirring evenly with a portable electric mixer to make it not contain undecomposed powder.

Evenly paint the bottom layer with a roller brush or paint brush, and the bottom must not leak out, and the general dosage is. After the coating is dry, the next process can be carried out.

3) Additional layers of details.

Parts prone to water leakage, such as floor drains, pipe roots, and yin and yang angles, should be sealed or strengthened.

Embedding sealing paste: According to the design requirements, the sealing paste should be embedded in the groove of the pipe root and other parts, which should be tightly pressed and embedded to prevent air from being entrapded, and firmly bonded with the seam wall, and there should be no cracking, bubbling and collapse.

Detail additional layer: in the floor drain, pipe root, yin and yang angle and entrance and exit and other weak parts that are prone to water leakage, a layer of carcass reinforcement material can be added, the width of the carcass reinforcement material should not be less than 300mm, and the lap width should not be less than 100mm. During construction, a layer of JS composite coating is applied first, then the carcass reinforcement material is laid, and finally a layer of JS coating is applied.

4) Paint the middle and surface waterproof layers.

The prepared waterproof coating is evenly brushed on the surface of the base layer, and the amount of each layer of brushing should be applied multiple times until the coating thickness requirement specified in the design is reached.

1) Test the water for the first time.

After the last waterproof layer is dried for 48 hours, the water is stored for 24 hours, and no leakage is qualified.

2) Protective layer or finishing layer construction.

After the first water storage test is qualified, the protective layer or finishing layer can be constructed.

3) Test the water for the second time.

After the protective or finishing layer is completed, a second water test should be carried out to ensure that the toilet is waterproof.
