Ask for waterproofing problems When the upstairs was renovated, a big hole was made around the bathr

Looking at this picture, whether he did it or not, first asked him to plug the hole, and it was uncomfortable to look at. It is recommended to use the plugging king and waterproofing agent to rub a little sand, the effect is particularly good. Secondly, after doing a good job of waterproofing, you must personally confirm that there is no leakage, and it is best to participate in the acceptance with the person in the property management, because if there is a problem, the property management has nothing to do with it.

To be honest, when I saw that hole, I was very skeptical that they could do it well.

Waterproof material has three points of material seven points of workmanship, the material is good to the aspect, workmanship is also very important, generally said that there are holes or nozzles where the elasticity of the material is good (such as the United States Shuanghong brand flexible waterproof coating), in the construction process if the safer approach is to add fiberglass cloth, if the nozzle around the void is large, then fill it with Shuanghong fast plugging king, this material has impermeability.

First of all, you have to make sure that he did it? You'd better go up and pour water yourself and try it yourself!

The bathroom is not sloppy, it is a place where there is always water!

You'd better do it yourself with plain cement first, and then do it again with a good German Sika waterproof!

It's not good to say, it should be safer to do multi-layer waterproofing.
