Teach you how to make your own waterproof!

I chose "Sika rigid" waterproof material, with 2 bags in each group, one bag is powder and the other bag is white liquid, which are used in proportion! The following is the experience: let's talk about rigidity and flexibility first. It stands to reason that the ground should be elastic. Why? Because cement is laid on the ground, there is no so-called problem of weak adhesion in flexibility. Why should walls be rigid? Then you understand that flexibility can't stand it. But a new problem has come. The key pipelines on the ground are all pvc. How to combine them with flexible waterproofing? So after careful consideration, it is better to use rigid ones! First of all, you must clean your bathroom, including the ground must not have all kinds of garbage, brick powder, cement caking, the wall must be flat. What kind of water improvement scheme should be considered in this process to determine when to start waterproofing. I'll finish the waterway reconstruction first (it's not safe to walk inside the wall and cross it, so it's better to take a vertical slot on the ground and lead it to the wall). After the gap cement is pasted, keep the wall flat and then clean it. Don't clean up all the bricks, ashes and cement blocks brought by water improvement, and don't let such substances exist between the original ground and the later waterproof layer. If necessary, wash the floor with washbasin water. Then the basement wall is dry before waterproofing. During the period, we should continue to carry out many sanitary cleaning, and sweep the floor if nothing happens. At this time, building materials such as sand may accumulate in the blank room, so avoid secondary pollution when cleaning! After the last floor drying, spray water with a coke bottle to make the floor and wall wet. When there is no clear water, start to brush Sika, and Sika will stir in proportion according to the instructions on the bucket. Note that the paint will be hard at this time. You can add water until the brush can be stirred at will! There is no strict water ratio, so don't make it too thin. While brushing and stirring, it is best to prepare a thin iron bar. If it is the first brush, the second brush will be from north to south to form a layer of net. Don't mix all the paints in proportion at once, but use a little, which can control the dosage well! Brush from the inside out, you can't get here after brushing, step on it! After the first drying, the second drying. Remember, when spraying some water, it is difficult for water to penetrate in time, but it stays on the first waterproof line in the form of water droplets! 1, there should be no damage and pollution between two times. The second pass is still carried out according to the first pass procedure. Remember to pay more attention to pipes, corners and walls every time you brush them, and brush them several times! Pay attention to the connection between the lines and the surroundings. Just twice, and it shall not be damaged or polluted before drying. Try to avoid stepping on the bathroom too often before laying tiles. When laying ceramic tiles, it is forbidden for craftsmen to carry out destructive operations such as cement and knocking on the waterproof floor of the bathroom, so as to avoid serious friction between the construction table frame and the waterproof layer! Otherwise, no matter how waterproof it is, it is no use! Bricklaying, digging old floor drains and installing new ones require experienced masters, which is also a crucial step! I wish you all success! I made it waterproof, don't worry! Watching many decoration companies smash tiles and redo waterproofing. I chuckled!
