In the modern home life, the bathroom water consumption is the largest, so the wall surface must be waterproof, otherwise not only the wall surface will have black moldy, off and other phenomena, here we introduce: wall surface Ground waterproofing and precautions.
Wall surface waterproofing
Waterproof treatment
Be sure to level the floor first with cement mortar and then do a waterproof treatment so that leakage of the waterproof coating due to uneven thickness can be avoided. The specific approach is, before doing waterproofing, be sure to clean the ground, with polyurethane waterproof coating repeated brushing 2 to 3 times. , And try to ensure the formation of a smooth, do not have large air bubbles in the process of laying the gap.
Waterproof treatment
The seams between the wall and the ground and the pipe seams between the upper and lower water are the most prone to problems. The corners must be properly handled. The decoration team is required to provide cement mulch to the upper and lower water pipes in the kitchen and bathroom. Brush a 10 to 20 cm polyurethane waterproof coating upward from the floor, and then re-do the polyurethane waterproofing on the ground, and add the original waterproof layer to form a composite waterproof layer. To enhance waterproofness. There will be a transfer excuse for the water pipes at the transition between the wall and the ground. It must be ensured that there will be no water leakage at the interface. After the installation is complete, the water test can be conducted.
Waterproof treatment
During the construction process, when the pipeline, floor drain, etc. cross the floor, the waterproof layer around the hole must be seriously constructed. Buried water pipes in the wall, so that a reasonable layout, decoration design, the laying of the water pipes must be neat and unified, do not mess scattered. Laying pipes shall be made of grooves larger than the diameter of the pipes. The grooves shall be smooth and smooth, and then the grooves shall be brushed with polyurethane waterproof coating.
Waterproof treatment
When the bathroom takes a bath, the water will splash on the adjacent wall. If there is no protection of the waterproof layer, the partition wall and the diagonal corner wall will become mildly damp. So be sure to waterproof the walls before you apply the wall tiles. In the general waterproofing process, the wall surface is to be treated with a waterproof height of 30 cm. However, for a non-load-bearing lightweight wall, the entire wall should be waterproofed, and at least 1.8 meters high should be achieved. The waterproof surface of the wall adjacent to the shower position should also be 1.8 meters high. If a bathtub is used, the height of the waterproof coating on the wall adjacent to the bathtub is also higher than the upper edge of the bathtub.
Ground waterproof construction precautions:
1, plastering shelf to leave the wall 15cm. When breaking the shelf, you must not touch the mouth and the wall.
2. Floor ash should be cleared up and used in time, so that you can live and work hard.
3, people on the ground can not be too early.
The prone to quality problems in ground waterproof construction:
1. Empty drums and cracks: The base layer was not well treated, and the surface of the concrete before brushing the pulp slurry was not cut. The oil stain was not cleaned with ash, resulting in empty drums and cracks. In addition, poor conservation and inadequate maintenance period are also one of the reasons.
2. Leakage: The plastering time of each layer is not properly mastered, and it is too tight to fall. The pulp is too dry, and the screed mortar is not easily bonded to cause water seepage. The detailed handling of the wall-to-wall and wall-pass pipes is not easy to handle, and it can easily cause partial leakage. During the construction, it must be carefully handled according to regulations.
