Construction Skills of Waterproof Engineering
一、做好水电基础工程
1. Improving Hydropower Foundation Project
从安全角度来讲，卫生间水管电线走上面比走下面好。但很多马路装修队伍贪图省力，水电走地上，甚至在卫生间开地槽，凿圆孔。这对防水施工来说是特别不利的。
From a safety point of view, it's better to walk up the toilet water pipes and wires than down. But many road decoration teams are eager to save energy, water and electricity on the ground, and even in the bathroom groove, drilling round holes. This is particularly disadvantageous to waterproofing construction.
二、清理基层和墙壁
2. Cleaning up the grass-roots and walls
首先，用小锤子敲墙面和地面，如果发现清脆和的空声，意味着里面有空鼓，必须把空鼓部分全部敲掉。然后仔细清理四个墙面基层和地面，拔掉铁钉，清理杂土垃圾，最好用清水冲洗一遍，然后待其干燥。
First of all, knock on the wall and the ground with a small hammer. If a clear and clear sound is found, it means that there are empty drums in it. It is necessary to knock out all the empty drums. Then carefully clean the four wall base and ground, pull out the nails, clean up the debris, it is best to rinse it with clean water, and then wait for it to dry.
三、准备涂料
3. Preparation of Coatings
一般是先以粗胚水泥打底，等水泥干了以后再刷防水涂料。刷涂料前，地面必须平整，不可以有凿孔或者凹槽。然后在地面上洒水，排出小孔内的气体。粉料与涂料搅拌时最好用电钻，搅拌后放5分钟。如果是人工搅拌要放10分钟。刷涂料时如果出现气泡，要把气泡刷开。
Generally, the base is made of coarse-grained cement, and then the waterproof coating is brushed after the cement has dried up. Before painting, the ground must be flat, and no holes or grooves should be allowed.jianlouyi.75ix.com   jianceyil.75ix.com   jianceyiq.75ix.com

When mixing powder and paint, it's best to use electric drill, and mix for 5 minutes. If it is stirred artificially, it will take 10 minutes. If there are bubbles in the paint, the bubbles should be brushed away.
