Ⅰ Detail processing
1. Internal and external corners: the connection between the ground and the wall should be plastered into an arc with a radius of 20mm.
2. Pipe root part: After the pipe root through the wall is positioned, the floor is tightly blocked with cement mortar, and the parts around the pipe root connected to the ground are plastered into a figure-eight shape with cement mortar.
3. Pipes and connecting parts through the wall should be installed firmly, and the joints should be tight.
Ⅱ Waterproofing layer construction:
1. Requirements for the base surface before construction: it must be flat, and there should be no defects such as gouges and grooves.
2. Before construction, the wall and ground need to be wetted with water to remove the air in the wall hole, so that the wall surface is denser and the surface is more permeable.
3. When mixing powder and liquid material, it is necessary to use an electric drill. After stirring at a constant speed, place it for 3-5 minutes; if it is manually stirred, it needs to be stirred for about 10 minutes, and then place it for 10 minutes before use.
4. When using, if there are bubbles in the slurry, the bubbles need to be brushed away, and there should be no bubbles.
5. Note: For brushing, you only need to brush in one direction in one pass, and in the opposite direction for the second pass.
6. The interval between the first and second brushing is preferably about 4-8 hours.
7. It is not easy to brush the thickness of the facade, and it can be brushed several times. When brushing, there will be holes of about 1.2-1.5mm, so it needs to be brushed in multiple times to increase its compactness and fill the void density.
8. Check whether the waterproof is qualified
After the waterproofing project is completed, seal the door and water outlet, fill the toilet floor with water to a certain level, and mark it. If the liquid level does not drop significantly within 24 hours and the roof of the downstairs does not leak, then the waterproofing is qualified. If the acceptance fails, the entire waterproofing project must be redone before acceptance. After confirming that there are no leaks, re-lay the floor tiles.
