防水济南涂料作为防水材料中的一个大类别，在防水工程中得到广泛应用。好的防水工程，材料的选择及的施工缺一不可。所谓“三分材料，七分施工”就形象的说明了施工对于材料性能大化中所起的作用。但是目前我们在防水材料使用过程中由于对材料本身的不了解，致使防水涂料的使用存在的较多的误区，下面就来看看吧。

Waterproof coatings, as a major category of waterproof materials, are widely used in waterproofing engineering. Good waterproof engineering, material selection, and professional construction are indispensable. The so-called "three parts for materials, seven parts for construction" vividly illustrates the role of construction in maximizing material performance. However, currently there are many misunderstandings in the use of waterproof materials due to our lack of understanding of the materials themselves. Let's take a look below.

误区一：水泥基类防水涂料施工前基层不做润湿处理

Mistake 1: Cement based waterproof coatings do not undergo wetting treatment on the base layer before construction

水泥基防水涂料(JS、K11等)作为防水涂料中的主要类别在家庭装修中往往作为选择，水泥基防水涂料在施工前，需要对基层进行润湿，保证防水涂料的性能优，往往很多施工者知道水泥基防水涂料施工前需要润湿基层，但是实际做的过程中往往忽视或者只是象征性的做一下基层润湿处理后直接刷防水涂料，由于基层未做润湿处理或者润湿不充分，导致水泥基防水涂料中的水泥水化不完全这样水泥基防水涂料的涂膜强度达不到要求，致使无法承受后续铺贴瓷砖带来的重量和瓷砖铺贴材料收缩所带来的应力，从而导致瓷砖空鼓脱落，给业主带来经济损失。

Cement based waterproof coatings (JS, K11, etc.), as the main category of waterproof coatings, are often the first choice in home decoration. Before construction, cement based waterproof coatings need to wet the base layer to ensure the excellent performance of the waterproof coating. Many construction workers often know that cement based waterproof coatings need to wet the base layer before construction, However, in the actual process, it is often overlooked or simply symbolic to apply waterproof coatings directly after wetting the base layer. Due to incomplete or insufficient wetting of the base layer, the cement hydration in the cement-based waterproof coating is not complete, and the coating strength of the cement-based waterproof coating cannot meet the requirements, resulting in the inability to bear the weight caused by subsequent tiling and the stress caused by shrinkage of the tiling material, As a result, the tiles will become hollow and fall off, causing economic losses to the owners.

划：水泥基类防水涂料施工前基层充分的润湿至关重要

Key points: Adequate wetting of the base layer is crucial before the construction of cement-based waterproof coatings

误区二：防水涂料加水

Mistake 2: Adding water to waterproof coatings

不可以！这是一个误区。很多人在做防水时喜欢加水，因为这样比较好刷，一旦加水量多，就容易导致涂膜太薄、流挂，防水功能大打折扣，这样做有很大的风险。楼固的防水材料有着严格的配比，必须按照包装指引进行施工，随意加水调稀，改变配比，会影响终的防水效果。

may not! This is a misconception. Many people like to add water when waterproofing because it is easier to brush. Once a large amount of water is added, it can easily cause the coating to be too thin, sagging, and the waterproofing function to be greatly reduced, which carries great risks. The waterproof materials of Lou Gu have a strict ratio and must be constructed according to the packaging guidelines. Adding water to dilute them at will or changing the ratio can affect the final waterproof effect.

划：防水涂料不能加水，会严重影响防水效果

Key point: Waterproof coatings cannot be added with water, which will seriously affect the waterproof effect

误区三：防水涂料只要厚度够了就可以了，刷几遍无所谓

Mistake 3: Waterproof coating only needs to be thick enough, it doesn't matter how many times it is applied

刷防水一定要按工艺要求一遍一遍地刷，上一遍完全干透了再刷下一遍，否则上层未干后层覆盖后期会产生空鼓起皮，如果为了图省事，把防水涂料倒在地上随便涂抹，各个部位有厚有薄，干燥的速度肯定不一样，厚的地方表面干了，下面还呈糊状，厚的地方与薄的地方干燥速度不一样，就会从厚薄交界处开裂，一旦此时闭水，防水就等于白做了。

When applying waterproofing, it is necessary to brush it again and again according to the process requirements. If the previous one is completely dry, the next one will be brushed again. Otherwise, the upper layer will not be dry and the later layer will be covered, resulting in hollowing and peeling. If the waterproof coating is poured onto the ground and applied casually to save trouble, the drying speed will definitely vary depending on the thickness of each part. The surface of the thick part will dry, but the bottom will still be mushy, and the drying speed of the thick part and the thin part will be different, It will crack at the junction of thickness, and once the water is closed at this point, waterproofing is equivalent to being done in vain.

划：防水涂料需要分两遍涂刷，不可一次涂刷过厚导致开裂

Key point: Waterproof coating needs to be applied in two coats, and cannot be applied too thick in one coat to cause cracking

误区四：防水涂料涂刷完24小时就做闭水测试

Myth 4: Conduct a closed water test after 24 hours of applying waterproof paint

防水全部施工完成并且完全干透后，需要进行闭水试验，一般在竣工48小时后进行。如果未完全固化时进行闭水实验，易造成防水层起翘、脱落等现象。防水涂料由于化学反应及物理挥发双向作用使防水涂料干燥形成具有防水能力致密的涂膜，但是化学反应及物理挥发均需要过程，当两个过程还未进行完成的时候进行闭水试验，会使涂膜与基层脱开，起泡等问题。

After all waterproofing construction is completed and completely dried, a closed water test is required, usually 48 hours after completion. If a closed water experiment is not fully cured, it is easy to cause the waterproof layer to warp and fall off. Due to the bidirectional effects of chemical reaction and physical volatilization, waterproof coatings dry to form a dense coating film with waterproof ability. However, both chemical reaction and physical volatilization require a process. When the two processes are not completed, conducting a closed water test can cause the coating film to detach from the base layer, cause foaming, and other problems.

划：防水涂料施工后短要过3-4天才能进行闭水试验

Key points: After the construction of waterproof coatings, it should be 3-4 days before conducting a closed water test
