Waterproof and leak-proof working methods:
1, primary treatment
First of all, the dust, oil stains and sundries on the surface of the base should be cleaned up to make it solid, flat and clean. For the wall root, the angle of yin and yang, the pipe root and other parts, cement mortar should be used to repair and smooth, and arc should be made to facilitate the application of waterproof coating.
2, wet the grass-roots level
Spray the wet base with roller brush or clear water, but there can be no water. This can increase the adhesion between the waterproof coating and the base, and reduce the absorption of the coating.
3, besmear brushs waterproof layer
According to different waterproof materials, choose appropriate painting tools, such as rollers, brushes, spray guns, etc. Waterproof layer should be painted in layers, and each layer should be uniform, without leakage, foaming and cracking. After each layer is brushed, wait until it is dry before brushing the next layer, and the direction of each layer should cross vertically. Waterproof layer should be painted more than twice, and the thickness should not be less than1.5mm..
4. Additional waterproof layer details
For parts with high water seepage risk, such as wall roots, pipe roots, floor drains, etc. On the basis of normal waterproof layer, additional waterproof treatment should be carried out for details. The specific method is to seal these parts with plugs or other special materials, then reinforce and fix them with waterproof tape or grid cloth, and finally brush waterproof paint again.
5. Water storage inspection
After the waterproof construction is completed, water storage inspection shall be carried out to check whether the waterproof effect is qualified. Water storage inspection time is generally more than 24 hours, during which it is necessary to regularly observe whether there is leakage. If there is leakage, find out the cause and repair it in time.
6, protective layer laying
After the water storage inspection is qualified, a protective layer should be laid on the waterproof layer to prevent the waterproof layer from being damaged in the subsequent construction or use. The protective layer generally adopts cement mortar or other isolation materials.
