1, brush the first time waterproof paint. Before construction, ensure that the construction site is clean and dry. The waterproof coating should be applied completely, with no omissions. It must be firmly bonded to the grass roots, free from cracks, bubbles, and shedding. The brushing height is the same and 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 is too short and the effect of waterproofing will be greatly reduced.
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 firm 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, you need to redo it, and you must not neglect it.
Primary treatment, cleaning, do leveling layer, bonding layer, additional layers, acrylic waterproof layer, water storage test, protective layer construction, secondary storage test.
1. Correctly check the elevation of the kitchen and toilet, and pay special attention to the correct position of the floor drain.
2. The quality of the wall leaks on the floor drains and pipelines should be carefully inspected. The wall holes should be densely packed and the roots of the pipelines must be required for caulking.
3, Yin Yang angle should be made into a circular arc, and straight, flat light.
4, leveling layer construction: base surface voids, cracks, inequality defects, repair and smooth with cement mortar. The base must be sturdy, smooth and clean, free of dust, grease, wax, mold release agents, and other debris.
5. After the leveling layer is dry, it can be used for waterproof layer construction. The construction period should be fireproof and waterproof. Construction workers should wear soft-soled shoes.
6, after the completion of the waterproof layer, to protect the finished product, no businessmen can move. After passing the inspection and passing the inspection, the company can apply for the concealed project acceptance visa before proceeding with the next process.
7. After the water-proof construction is completed, a water storage test is conducted and no leakage is considered qualified after more than 24 hours. After the installation of the equipment is completed, a secondary impoundment test is performed.
