During the decoration, we are afraid that the bathroom leaks, because it is a hidden project, so it is difficult to repair after the tile is finished. It is not necessarily able to find the leak when the tile is used, unless it is re-furnished once again, it is not only time-consuming. The cost is not low, so many owners choose to re-do the waterproof layer.

A landlord reflected that he also wanted to protect the bathroom at home from leaking water. During the renovation, he bought a large bucket of waterproof paint, and he personally brushed it three times. However, after staying for 3 months, he found that the bathroom leaked, so he found it. The decorator wants to see if there is any way to repair it. The decorator came over and looked at the owner and said: You don’t understand at all. If some details are not noticed, it is useless to brush 10 times.

The first point to note is that when brushing the waterproof layer, be sure to pay attention to some corners. This place is the focus of painting, because there are many subtle settlements in the later buildings, and the ground and wall corners are very easy to appear. The place where the water leaks.

The second point of attention is the place where the water pipe and the floor drain are located. These places are the places with the highest probability of water leakage. The ten times of leaking water for ten times will be the water leakage between the water pipe and the ground, so the paint must be in the lower ppr pipe. It is best to make several times of waterproofing around the roof. It is best to make the corners of the down pipe and the ground curved, and then the waterproof layer is more secure.

Thirdly, the base layer of the waterproof layer should be firm, and there should be no floating particles and floating dust and small construction residues. If the waterproof layer is brushed on the top, it is easy to loosen or cause the waterproof layer to detach or leak, otherwise it will be brushed. It is also a white brush.

The fourth point, the material of the ground can not be stretched or cracked. For example, some cement layers have a certain expansion ratio after construction. Do not apply when the cement layer is not dry. Otherwise, it will easily cause water to disperse and not be waterproof. The quality of the layer will also have a certain impact.

The fifth point, many owners feel that the thicker the waterproof layer, the better the number of brushes, the better, in fact, this is also a misunderstanding, after the waterproof layer reaches a certain thickness, it is too thick, not only waste unnecessary materials for waterproofing The layer is not good, the waterproof layer should choose the appropriate waterproof material, on the one hand, the hardness of the waterproof layer, and one index is the flexibility of the waterproof layer, both of which are indispensable.

Finally, after completing the waterproof layer, you must do a water shut-off test, plug the floor drain of the bathroom, and then put a tap water of about 3 cm deep. After 24 hours, check whether the water volume has changed significantly. Go to the neighboring house and look at the roof. Is there a watermark, so as to ensure the quality of the waterproof layer, whether it is the owner’s own hand brush, or the construction worker’s brush should be constructed according to the standard, otherwise it is a foolish thing, let alone brush 3 times is the same as brushing 10 times!
