How to deal with wall damp

　　由于腻子是碱性的，水后会是碱性的，墙面干燥后轻易出现黄色痕迹，尤其是墙面干燥、潮湿接缝时，痕迹更明显。

　　Because putty is alkaline, it will be alkaline after water, and yellow traces will easily appear after the wall is dry, especially when the wall is dry and wet, the traces are most obvious.

　　现在施工多采用防霉腻子，墙面吸水后一般不会发霉。

　　Now, anti mildew putty is widely used in construction. Generally, the wall will not get moldy after absorbing water.

　　1、瓷砖受潮变色处理

　　1. Treatment of tile discoloration due to moisture

　　瓷砖受潮后，会产生颜色变化，颜色会变暗，但不会变颜色;瓷砖干燥后，可以恢复原来的颜色。

　　When the tile is damp, it will produce color change, and the color will be dark, but it will not change color; when the tile is dry, it can restore the original color.

　　2、壁纸潮湿处理

　　2. Wet treatment of wallpaper

　　贴壁纸的墙面受潮后，壁纸就有可能变得翘曲、变形和变色。而乳胶漆墙面不同，装修壁纸墙面对温湿度没有什么要求，但装修破坏壁纸墙面必然产生色差，建议整体更换墙面壁纸。在修补壁纸墙面时，将损坏的壁纸撕掉后直接刷一层壁纸胶，粘贴壁纸即可。

　　When the wall with wallpaper is damp, the wallpaper may become warped, deformed and discolored. But the emulsion paint wall is different, the decoration wallpaper wall has no requirements for temperature and humidity, but the decoration damage wallpaper wall will inevitably produce color difference, so it is recommended to replace the wall wallpaper as a whole. When repairing the wallpaper wall, tear off the damaged wallpaper and directly brush a layer of wallpaper adhesive, then paste the wallpaper.

　　具体碱度原因及处理方法

　　Specific alkalinity reason and treatment method

　　在建筑工程中，混凝土的主要成分是弱酸强碱盐，这种材料遇水后，会产生化学反应，形成游离钙、硅酸盐和碳酸盐等盐材料。混凝土在中间有一个差距,随着时间的推移,水携带的盐混凝土材料在混凝土表面移动,游离钙、硅酸盐和碳酸盐蒸发盐材料后,将结晶成白色粉末晶体,晶体的一部分,然后与空气中的二氧化碳反应,凝结成白色块状物在混凝土的表面,这是通常被称为“具体FanJian”。

　　In the construction engineering, the main component of concrete is weak acid and strong alkali salt. When this material meets water, it will produce chemical reaction and form free calcium, silicate, carbonate and other salt materials. There is a gap between the concrete and the concrete. Over time, the salt concrete material carried by water moves on the concrete surface. After the free calcium, silicate and carbonate evaporate the salt material, it will crystallize into a white powder crystal, a part of the crystal, and then react with the carbon dioxide in the air to condense into a white block on the concrete surface, which is usually called "specific Fan Jian".

　　虽然混凝土是非常普遍的现象，但一旦混凝土出现，就会出现两个负面影响:

　　Although concrete is a very common phenomenon, once concrete appears, there will be two negative effects:

　　一是减少了混凝土中的盐，形成了碱度，这部分混凝土的钢筋会开始腐蚀。

　　One is to reduce the salt in the concrete and form the alkalinity, and the reinforcement of this part of the concrete will start to corrode.

　　第二部分是碱度发生的地方，碱度通常是由水分或渗漏引起的，导致过量的水流动并除去盐分。

　　The second part is the place where alkalinity occurs. Alkalinity is usually caused by water or leakage, causing excessive water flow and removing salt.

　　1、混凝土易出现碱性条件的现象

　　1. The phenomenon of alkali condition in concrete

　　(1)水泥质量问题。如果混凝土是由纯波特兰水泥和普通波特兰水泥制成，大量的氢氧化钙被水带到混凝土表面形成碱。

　　(1) Cement quality problems. If the concrete is made of pure Portland cement and ordinary portland cement, a large amount of calcium hydroxide is carried to the concrete surface by water to form alkali.

　　(2)混凝土结构。如果混凝土结构过于松散而不紧密，那么混凝土内部的水很容易渗透到外部，也会造成碱度。

　　(2) Concrete structure. If the concrete structure is too loose and not tight, the water inside the concrete is easy to penetrate to the outside, which will also cause alkalinity.

　　2. 如何防止混凝土返碱

　　2. How to prevent concrete from alkali return

　　(1)中和混凝土中多余的盐。

　　(1) Neutralize excess salt in concrete.

　　施工过程中，在混凝土中加入粉煤灰、矿粉、硅灰等活性外加剂。这些物质将与水泥中的盐发生二次反应，将氢氧化钙转化为硅酸钙凝胶，使它们在表面下“游动”。或直接使用复合水泥。

　　In the process of construction, fly ash, mineral powder, silica fume and other active admixtures are added to the concrete. These substances will react with the salts in cement for the two time, transforming calcium hydroxide into calcium silicate gel, enabling them to swim under the surface. Or use composite cement directly.

　　(2)降低混凝土的渗透性。

　　(2) Reduce the permeability of concrete.

　　为了降低水泥的渗透性，可以使用一些防水剂。

　　In order to reduce the permeability of cement, some waterproof agents can be used.

　　3.混凝土退碱处理

　　3. Alkali removal of concrete

　　对于已经有碱度现象的水泥所，要先重新清理治理(如碱度的墙面不处理，以后的涂料层轻易起壳、脱落)。混凝土碱度低，如外墙渗水，需涂一层防水材料。对于已经碱性的混凝土墙，先用硬毛刷(必须是干毛刷，用酸洗或中和也不可能完全除去)多刷几次，清洗干净;然后刮层腻子底，配料为建筑白水泥、腻子粉和JS防水材料;之后才能按照正常的流程进行装修。

　　For the cement place with alkalinity, it is necessary to clean up and treat it again first (for example, the wall with alkalinity is not treated, and the coating layer will easily shell and fall off later). The alkalinity of concrete is low. If the exterior wall seeps, a layer of waterproof material shall be applied. For the alkaline concrete wall, first use a hard brush (it must be a dry brush, which can not be completely removed by pickling or neutralization) for several times, and clean it; then scrape the bottom of the first layer of putty, which is made of building white cement, putty powder and JS waterproof material; after that, the decoration can be carried out according to the normal process.

　　(1)先用硬毛刷清洁水泥表面;高压水枪可以用在顽固的地方。对于不溶于水的物质，要用稀释后的弱酸清洗，如5~10%的盐酸溶液。使用弱酸溶液时，注意保护干净的墙面不受酸性物质的侵蚀。

　　(1) Clean the cement surface with a hard brush first; high pressure water gun can be used in stubborn places. For water-insoluble substances, dilute them with weak acid, such as 5-10% hydrochloric acid solution. When using weak acid solution, pay attention to protect the clean wall from the erosion of acid substances.
