What if the expansion screw is hung on the ceiling of the bathroom and the waterproof layer is opened?

Further waterproof construction is required. It is recommended that you choose waterproof products of Oriental Yuhong and standardized construction team. Oriental Yuhong is the best waterproof listed company in China. It is a powdery waterproof plugging material made of special cement and additives through a special process, which is used as a matrix for leakage or water gushing. \x0d\ There are three kinds of water leakage in general waterproof works, namely, point leakage, joint leakage and area leakage. According to the specific situation of water leakage in the project, quick-setting waterproof and plugging treasure can be used, and different water stopping and plugging technologies can be used to deal with it. \x0d\ 1。 Waterproofing and plugging of leaking holes \x0d\ Waterproofing treatment of parts around leaking holes. Use powder: water = 1:0.35, mix the powder with water, and apply it around the leakage hole. Generally use a trowel or scraper for 2~3 times, and the material used each time is about 1.2Kg/m2. After each coating is hardened (without fingerprints), spray it wet (but without water), and then proceed to the next step of construction. \x0d\ Remove the circular groove for plugging. Centering on the water leakage point, carve a groove (the groove diameter × depth is 10mm×20mm and 20mm×30mm, and the general capillary seepage carves a round hole with a diameter of 10mm), and rinse the groove with water. Mix the powder with water and knead it into a cone with a diameter close to that of the tank. When it feels hard by hand, put it into a jar, squeeze it with a wooden stick, tap it to make the inside and the surrounding area solid and dense, and then stop the water instantly. \x0d\2。 Waterproof and plugging of water leakage cracks \x0d\ Waterproof treatment of surrounding parts of water leakage cracks. Use powder: water = 1:0.35, mix the powder with water and apply it around the leaking gap. Generally use a trowel or scraper for 2~3 times, and the material used each time is about 1.2Kg/m2. After each coating is hardened (without fingerprints), spray it wet (but without water), and then proceed to the next step of construction. Lift the splayed groove for plugging. Dig a splayed groove with a depth of 10mm~30mm and a width of 15mm~50mm along the crack. Put a small rope along the crack at the bottom of the cylinder. The length of the rope is about 200 ~ 300 mm After mixing the powder with water, knead it into strips and leave it for a while. When it feels hard by hand, fill it in the groove where the rope is put, quickly compact the edge, then pull out the rope and compact it again to make the water leak out along the rope hole. For longer cracks, they can be filled step by step, and the length is about 100mm~ 150mm, with a gap of 20mm wide for each gap. At the gap of 20mm, when the mixture is about to solidify, insert the nail wrapped with the mixture into the gap and quickly compact the gap around the nail with the mixture. At the same time, rotate the nail and pull it out immediately to make water flow out along the nail hole. After the sealing material is solidified, the nail hole is treated according to the waterproof sealing method of the leaking hole. \x0d\3。 Treatment of large-area water leakage \x0d\ When plugging, water must be diverted to relieve pressure first. The principle of water diversion is to change surface leakage into line leakage and point leakage, so as to minimize the water leakage and concentrate the water leakage on one or several points to reduce the seepage pressure in other parts. After that, waterproof and plugging shall be carried out according to the treatment method of point leakage or line leakage. \ x0d \ x0d \ wallbillie interfacial agent (concrete interface treatment agent) \ x0d \ x0d \ concrete interfacial agent mainly refers to a product which can obviously improve the bonding strength between concrete and other products by increasing the roughness of concrete surface or its own strength, and is widely used in surface treatment of various cement bases. \x0d\ Wallbury interface agent (concrete interface treatment agent) is a new type of high permeability material composed of polymer emulsion and multifunctional additives.

After it is completely dried, the next working procedure can be carried out. \x0d\3。 Brushing the base course \x0d\ Mix the interface agent and cement (recommended 42.5 ordinary portland cement) into mixed slurry according to the ratio of 1:2, and brush 1-2 times on the base course with a hard brush, with a thickness of about 2mm. After hardening, it can enter the next process. \ x0d \ x0d \ color tile sealant (soft and delicate) \ x0d \ x0d \ tile sealant is a mixture of cement, filler, pigment and modifier, which is used to fill gaps between tiles.
