When it comes to waterproof construction, our kitchen and bathroom are also the more serious water-proof places. So whether or not everyone is ready for this kind of construction, there is none. In the following, we will give you a list of several high-quality waterproof constructions. Have a look.
First, waterproof construction process
1, do a good job at the basic level
Before the waterproof construction, it is necessary to do a good job in the primary treatment of the wall, and it is necessary to ensure that the surface of the primary layer is solid, non-powdering, peeling, and drumming. At the same time, the surface of the base must be clean, free of dust, mold release agent, etc., which will affect the adhesion of the paint. Moreover, the surface of the grass-roots level should be smooth, with no major defects, and no obvious scars.
The treatment method is usually to carefully clean the base surface to remove the dust, remove the cement and loosen the base layer; special treatment shall be taken for the roots, drainage holes, yin and yang angles, and voids left on the wall after the hydropower reform. The yin and yang corners should be wiped. Rounded (or V-shaped). After processing, use a brush to sweep the dust on the base surface, dilute the appropriate amount of waterproof paint to milk, and dip the diluted material to the bottom with a roller. Brush the water-repellent surface on the front wall and back wall to completely remove dust.
2, how to brush the construction
After doing a good job at the grassroots level, we must begin to apply waterproofing paint. We must pay special attention to the comprehensive waterproofing. For the buried water pipe in the wall, we must cut out the groove larger than the pipe diameter, plaster the groove, and brush the waterproof coating. . If the original drainage and sewer pipes and floor drains are changed during the renovation, waterproof measures must be taken in the surrounding area.
3, standard construction to do a good job of waterproofing
General brush waterproof height can be determined according to need, in general, bathroom waterproof 180 cm high, non-shower wall in principle, waterproof paint can not be less than 35 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. Waterproof coatings must be brushed to the 1.5mm thickness of the national acceptance specification.
Different waterproof coating construction methods are not the same. However, when brushing, it is similar to general liquid paint. 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.
Second, pay attention to the construction of small details
When brushing, it is necessary to pay attention to using a brush or a roller brush to brush on the base surface firstly, and use evenly to make sure that it cannot leak the brush. Generally, it needs to be brushed twice (according to the use requirements), and the thickness of each brushing should not exceed 1mm. The first time after a little dry solid after the first brushing (just not sticky), vertical and horizontal cross brushing, brushing the total thickness is generally 1-2mm; if the coating has been cured, when brushing another layer Wet with water.
