Conscientiousness is an attitude, and standardization is the attitude of waterproof construction. In order to control the quality of domestic waterproof construction reasonably and effectively, it is necessary to have a clear and objective understanding of each link of waterproof construction, clear its construction steps and correct construction methods.
Standard construction procedures for waterproofing of toilet furniture
1. Site investigation and recording
Check the waterproof base, measure and calculate the waterproof construction area, post and fill in the construction flow form.
2. Handle the grass roots
Prepare construction equipment and materials, clean the base, ensure the base level is smooth, no cracks, no sharp, convex, meet the requirements of waterproof layer construction.
3. Handle details
The groove around the pipe root is 20mm wide and 10mm deep. After cleaning and cleaning with a brush, fill the stop water bar, and then wipe the stop water for radian treatment. The corner of the Yin is treated with stoppage and arcing.
4. Adhesive tape
The waterproof construction of wall should be carried out first, and the scope of wall painting should be determined. Metope top and floor board of kitchen and bathroom should be pasted with metope tape.
5. Waterproof additional layer construction
A 300mm wide waterproof coating film enhancement layer was made at the root of floor drain, floor drain pipe, and wall ground interface, and 150mm each for plane and elevation. First brush the coating film, then apply the mesh cloth, and then brush the coating film on the surface of the mesh cloth to ensure the non-dew cloth. The film thickness of the additional layer is up to 1mm.
6. Waterproof coating construction
In the coating to dry fully before again the next time the construction, such as testing have not curing phenomenon, need to strengthen ventilated for a period of time, again, achieve all testing point on the surface after curing, can be on to the next time coating brushing. The direction of the two-pass film brush is perpendicular to each other to avoid local leakage and the phenomenon of outcropping. After the painting is finished, ensure the air circulation at the waterproof construction site, and set warning signs at the door to avoid damage before the coating solidifies.
7. Closed water test
After the waterproof coating film is completely dry, the water outlet is sealed and the water shutoff test is conducted for no less than 24 hours. The water level at the highest point of the plane is no less than 20mm.
8. Final acceptance and protective layer construction
After passing the closed water test, the ground will be drained of water. Cement mortar is used to make a protective layer of cement mortar with a thickness of 1cm and a thickness of 1:3 on the surface of the planar coating film, so as to avoid damaging the coating film in the later decoration construction.
Matters needing attention
▶ due to internal Angle place is easy to crack, so need to do with arc processing;
▶ construction waterproof coating layer thinner coating, coating to dry for each time, can not glue the hand next time brushing;
▶ finally again after construction completely dry (pressure not sag) can be closed water test.
