The waterproof construction of the bathroom has always been one of the most prone to problems in home decoration. It is not uncommon to see moldy furniture, water seepage in walls, and even neighbor disputes caused by inadequate construction or unqualified waterproof materials. Only by using qualified waterproof materials and constructing in strict accordance with the process requirements can all kinds of troubles be eliminated and the decoration really worry-free.
Construction preparation
Before carrying out waterproof construction, the original rough ground must be strictly inspected to see if there is any hollowing. If there is a hollow on the ground, it must be repaired before proceeding to the next step of construction.
Most of today’s rough houses in Xinjiao are equipped with floor drains with balls. This kind of floor drain has a good anti-leakage function. You should try not to replace it during decoration to avoid leakage.
It is best to do a closed water test before waterproof construction. During the test, carefully observe the water launching speed of the floor drain. If the water is launched quickly and accompanied by a grunting sound, it indicates that the water is well launched. Otherwise, it should be dredged before decoration.
construction process
When draining the sewer pipes in the bathroom, the pipes should be slotted from the ground. And pre-coat the waterproof material before putting the water pipes. The paved pipeline should be filled with glue and mixed with cement to ensure that there will be no leakage.
If the back of the bathroom is the wall of the living room or bedroom, then the waterproof material should be painted from bottom to top during construction, and the waterproof height of the wall should be more than 1.8m, so as to effectively block the intrusion of moisture.
When the floor of the bathroom is raised, it is not allowed to fill the bottom layer with sundries or even construction waste. The correct process is to use cement to mix yellow sand and melon seeds, and use the mixed concrete to raise it.
Before laying wall and floor tiles, the ground should be cleaned and carefully coated with professional waterproof materials to ensure that the waterproof base surface is dense and prevent any capillary pores from becoming the culprit of leakage in the bathroom.
In order to have a good waterproof construction effect, a flooding slope on the ground should be prepared in the shower room. The standard flooding slope is generally about 1%, which can not only ensure that there is no water accumulation, but also prevent people from feeling excessively inclined when standing .
When laying wall and floor tiles, they must be soaked fully first. The proportion of cement, glue and yellow sand used for tiling needs to be reasonably configured and wait for 20 minutes before use. The tiles pasted in this way are very strong and can prevent the intrusion of water vapor.
After the wall and floor tiles are pasted, the supervisor should carefully check them one by one. The wall and floor of the bathroom should not appear hollow tiles. Only by sticking the tiles on these important parts can they become the first line of defense against water .
After laying the tiles, you should also pay special attention to the surroundings of the floor heating pipes, downpipes and sewage pipes. The gaps between these places and the tiles are usually the key parts of leakage. In addition to using cement to repair, it is best to use silica gel to seal if necessary.
The bottom of the door cover in the bathroom is also an important part that needs to be waterproofed. In order to prevent indoor water and moisture from causing mildew on the door cover, floor tiles or marble must be used to make the water-retaining threshold during construction.
Editor’s reminder: In addition to the above steps during waterproof construction, you should also pay attention to blocking all the sewers in the bathroom after the construction is completed, and conduct a 24-hour closed water test. Only when there is no leakage on the wall and floor can it show that the waterproof quality of the bathroom is good. After all waterproofing is done, tile grout cannot be ignored. Choosing a good sealant product can effectively block water vapor from entering the interior of the tile and ensure a good waterproof construction effect.
