Waterproof sealing process waterproof sealing material

Waterproof plugging, as its name suggests, is the construction of indoor and outdoor water-repellent treatment of buildings and the leakage of leaks inside and outside the room. Broadly speaking, this is a treatment for the treatment of space objects such as water repellent treatment and fluid and liquid trapping. Waterproof trapping project has a very important position in our lives and is closely related to our life. Next, Xiaobian introduced waterproof trapping procedures and waterproof trapping materials for everyone.

Waterproof plugging process

1, brush the first time waterproof paint. Before construction, ensure that the construction site is clean and dry. The waterproof coating should be completely filled with no missing material. It should be firmly bonded to the grass roots, free of cracks, bubbles and no shedding. The brushing height is the same. The thickness must meet the product requirements.

2, brush the second time waterproof coating. Note that there is a certain time interval between the first and second pass of the waterproof coating. After the first pass of the coating, the second pass can be performed. The specific time depends on the coating. The interval time is too short, and the effect of waterproofing will be greatly reduced. Therefore, it should be noted whether the construction workers have been “lazy” in this regard.

3, shop protection layer. In order to prevent the subsequent construction from damaging the waterproof layer, a protective layer should be applied on the surface of the waterproof coating. The protective layer must completely cover the waterproof layer without any omission. It has a strong bond with the grass roots, no cracks, no bubbles, and no shedding.

4, closed water test. In the closed water test, the water at the highest point on the ground must not be lower than 2 cm, and it should be stored for at least 24 hours, and it should be considered as qualified after observing no leakage. If there is leakage, it needs to be redone and you must not neglect it.

1, PM108 neoprene waterproof glue: applicable to all kinds of plants, residential roof waterproof, two cloth six coated, 2 kg per square meter.

2, PA108 elastic polyurethane waterproof rubber: applicable to all kinds of roof, waterproof, 1.6 kg per square meter, a cloth three.

3, PM110 roof waterproof glue: apply to the old and high-end waterproof roof, a four-coating, 2 kg per square meter.

4, PM109 advanced caulking ointment: applicable to crack repair of various buildings, roof expansion joints, structural joints, pools, seams joints waterproof.

Waterproof trapping base requirements

The interface with the waterproof material must not have bulging, sanding, beehive, wood, paper scraps, sludge, small stones, nor can it be done on a loose loose body because of poor adhesion and The destruction of the sun's ultraviolet rays, the thermal expansion and contraction of the building itself, and the destruction of water vapor pressure can easily cause the waterproof layer to deteriorate and fail.

If the roof is waterproof, it should be directly on the roof surface. The wall waterproofing should be done directly on the outer wall. The water leakage in the tank is done directly on the inner layer of the tank. The water will spread to other parts of the tank. The corners of the house are not easy to construct. The "superiority" mentioned here is relatively comparative, not absolute. With the development of science and technology, there have been the introduction of waterproof materials for back surface construction and the use of high- and low-pressure synthetic resin to produce expanded crystals, which can also be waterproof. However, not all occasions can be successfully constructed, so they must be adopted. Waterproof construction.

Editor's summary: The waterproof trapping process and waterproof trapping materials are introduced here, and we hope to help everyone. If you want to know more about yourself, you can follow the information on this site.
