& emsp;& emsp; When waterproof in the bathroom，Pay attention to the following points，Otherwise, it may cause leakage。
& emsp; & emsp; First of all: try not to destroy the original waterproof layer
& emsp; & emsp; in the newly delivered building，bathroom、Bathroom、The floor of the kitchen has a waterproof layer made in accordance with relevant specifications，As long as it does not destroy the original waterproof layer，Generally, there will be no leakage。
& emsp; & emsp; but the common problems now are: add some bathroom facilities in the decoration，Re -arrange or move all kinds of water pipes，Destroy the original waterproof layer，No timely restoration or re -waterproof construction，Leakage is easy to occur。Second: If you lay heavy floor tiles，Floor waterproof
& emsp; & emsp;，After cutting the original floor tile，You must first find the ground with cement mortar，Then perform waterproof treatment，Avoid uneven thickness and cause waterproof coating leak。Before waterproof，You must clean up the ground，Repeated brush 2 to 3 times with waterproof coatings with polyric acid。
& emsp; & emsp; 3: Must be waterproof and waterproof
& emsp; & emsp; during bathing，It will splash on the neighboring wall。If there is no protection of the waterproof layer，Partitioned walls and top corner walls are easy to wet and moldy。Therefore，Before laying wall tiles，Be sure to do a good job of waterproofing the wall。Generally speaking，Wall surface should do 30 cm high waterproof treatment。but，For non -loading lightweight walls，The entire wall should be waterproof，At least 1.8 meters high。
& emsp; & emsp; four: water pipe tank in the wall must also be waterproof
& emsp; & emsp; during the construction process，Dangdang、When the floor drain passes through the floor，The waterproof layer around the hole must be carefully constructed。The water pipe buried in the wall should be reasonable。When laying a water pipe，Should be a slot that is greater than the pipe diameter。Plasma smoothly in the groove，Then brush the polyinetine waterproof coating in the groove。
& emsp; & emsp; during the renovation process of second -hand and old houses，The transformation of hydropower lines is a particularly important project，Almost every family will involve。Especially some old houses，If you do not change water and electricity，Can't use it normally，It is even prone to fire、Danger of running water。So，In such an important transformation process，What should we pay attention to?
& emsp; & emsp; waterway transformation is very necessary。Houses with a service life of more than 15 years，During the second decoration，The water pipe must be transformed。
& emsp; & emsp; First，In a place where the water quality is hard，After the water pipe is used for a long time，Mineral material will be deposited in the inner wall of the water pipe，Dirty，Lead more impurities in the water，Affecting family water health。
& emsp; & emsp; second，Most of the houses built before 1990 are used in galvanized iron pipes。Due to the oxidation of water，will cause local corrosion and pollution of pipelines，Especially the internal and external parts of the water pipe connector sleeve，Easy to rust，Reduce resistance，Leaks leak、Cracking or even water pipe broken。After 1990，Popular aluminum-plastic tube or PP-R pipe、PE pipes and other new water pipes will also crack aging，In practice, it happened。
