At that time, White Snake flooded the Jinshan Temple to save Xu Xian and touched countless audiences. People admired this eloquent love. However, the story is always a story. In reality, it would be romantic if it drowns the family. Home improvement waterproofing is an important part. If it is not done well, the family can become a fish pond in minutes, leaving the sea view without leaving the house. So, let's learn together about the construction method of the waterproof coating.
I. Construction preparation: do a good job at the primary level
Waterproof grass-roots requirements: In the waterproof construction before the construction of the wall, the ground to ensure that the grass-roots surface solid, no cracking, pulverization, peeling, from the drum and so on. At the same time, the surface of the base must be clean, free of dust, mold release agents, etc., which will affect the adhesion of the paint.
Grassroots treatment method: firstly carefully clean the base surface to remove floating dust, remove cement agglomerates and loosen the base layer; carry out special treatment on roots, drainage holes, yin and yang angles, and voids left on the wall after the hydropower reform, etc. Should be rounded (or V-shaped). Uneven, cracked parts need to be repaired and leveled.
Second, construction preparation: Proportional deployment of waterproof coating
In the past, waterproof materials only required simple brushing. Nowadays, new waterproof coatings are mostly two-component or even three-component. Therefore, before construction, you need to understand how to deploy and how much to deploy. If not proportioned, the formulated waterproof coating may not achieve the original effect.
Third, brushing method: the first wall after the ground
Waterproof paint is similar to general liquid paint when it is applied, and it is brushed from the bottom to the top and back to the front wall. When using, if there is a bubble in the slurry, the bubble needs to be opened, and no bubbles can exist. The first pass only needs to be applied in one direction, and the second pass is done in the opposite direction. The time between the first pass and the second pass is preferably about 4-8 hours.
Fourth, special treatment: caisson treatment of the bathroom backfill
Many bathrooms generally do caisson and therefore need to be backfilled. Before backfilling, it is generally necessary to do a waterproof and then backfill after the water closure test. After backfilling, leveling requires a further layer of waterproofing.
V. Construction Standards: Waterproof Height and Thickness Index
In general, the bathroom waterproof 180 cm high, non-shower wall in principle waterproof paint can not be less than 30 cm. However, in order to enhance the waterproof effect, it is recommended to achieve a uniform height of 180 cm. In addition, it is recommended that the waterproof height be the top for light walls and self-built light walls that have been remodeled in toilets. In terms of thickness, the waterproof coating must be brushed to the 1.5mm thickness of the national acceptance specification.
Waterproof projects can not be sloppy, and construction quality must be strictly controlled so as not to affect the normal life in the future. The above is the introduction of the waterproof coating construction process.
