Is it normal to be waterproof and white?
If it is only slightly whitened locally, it is a normal phenomenon and has little influence on the quality of waterproof layer, so it can be left untreated. Of course, if there are serious whitening and strength problems, it needs to be carved out of the roots and rebuilt.
What are the reasons for the whitening of waterproof layer?
1. Meet Mingshui
There are many reasons for encountering Mingshui, but they are mainly divided into two situations: before brushing waterproof and after brushing waterproof.
First, there is clear water at the grass-roots level: for example, water is added to waterproof paint, which will get damp during maintenance.
Second, there is clear water after waterproof construction: after brushing waterproof paint, it accidentally meets water.
Suggestion: No matter before or after construction, there should be no open water. In addition, the base must be wetted before waterproof construction, but there must be no Mingshui.
2. Weather
Wet, low temperature and other weather lead to slow drying and curing of the waterproof layer, which leads to whitening of the waterproof layer.
Suggestion: avoid wet weather and construction when the temperature is below 5℃
Step 3 brush your teeth unevenly
If the waterproof coating construction is uneven, it is very likely to lead to whitening of the waterproof layer. If it is partially whitened, but there is no water seepage after the water storage test, it means that the whitened part has little influence on the waterproof layer and can be left untreated. However, if serious whitening or strength problems occur, resulting in water leakage, it is necessary to carve out the roots and rebuild them.
Suggestion: the thickness of the waterproof layer on the ground is 1 ~ 1.5mm, and it is recommended to apply 1 ~ 2 times to the water-permeable parts such as floor drains and pipelines.
4. Mix the color with the basic cement.
During construction, the paint is brushed thin and easily mixed with the color of the base, which will appear white, but it is not white in fact. As long as there is no problem in the water storage test, no special treatment is needed.
Suggestion: the waterproof layer is not easy to brush too thick or too thin.
