防水涂料日常使用中存在典型的幾個誤區(qū)

來源：http://www.wavc.cn 日期：2023-04-22 發(fā)布人：

防水濟南涂料作為防水材料中的一個大類別，在防水工程中得到廣泛應(yīng)用。好的防水工程，材料的選擇及的施工缺一不可。所謂“三分材料，七分施工”就形象的說明了施工對于材料性能大化中所起的作用。但是目前我們在防水材料使用過程中由于對材料本身的不了解，致使防水涂料的使用存在的較多的誤區(qū)，下面就來看看吧。

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.

誤區(qū)一：水泥基類防水涂料施工前基層不做潤濕處理

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)作為防水涂料中的主要類別在家庭裝修中往往作為選擇，水泥基防水涂料在施工前，需要對基層進行潤濕，保證防水涂料的性能優(yōu)，往往很多施工者知道水泥基防水涂料施工前需要潤濕基層，但是實際做的過程中往往忽視或者只是象征性的做一下基層潤濕處理后直接刷防水涂料，由于基層未做潤濕處理或者潤濕不充分，導(dǎo)致水泥基防水涂料中的水泥水化不完全這樣水泥基防水涂料的涂膜強度達不到要求，致使無法承受后續(xù)鋪貼瓷磚帶來的重量和瓷磚鋪貼材料收縮所帶來的應(yīng)力，從而導(dǎo)致瓷磚空鼓脫落，給業(yè)主帶來經(jīng)濟損失。

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.

劃：水泥基類防水涂料施工前基層充分的潤濕至關(guān)重要

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

誤區(qū)二：防水涂料加水

Mistake 2: Adding water to waterproof coatings

不可以！這是一個誤區(qū)。很多人在做防水時喜歡加水，因為這樣比較好刷，一旦加水量多，就容易導(dǎo)致涂膜太薄、流掛，防水功能大打折扣，這樣做有很大的風(fēng)險。樓固的防水材料有著嚴格的配比，建議按照包裝指引進行施工，隨意加水調(diào)稀，改變配比，會影響終的防水效果。

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.

劃：防水涂料不能加水，會嚴重影響防水效果

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

誤區(qū)三：防水涂料只要厚度夠了就可以了，刷幾遍無所謂

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

刷防水一定要按工藝要求一遍一遍地刷，上一遍完全干透了再刷下一遍，否則上層未干后層覆蓋后期會產(chǎn)生空鼓起皮，如果為了圖省事，把防水涂料倒在地上隨便涂抹，各個部位有厚有薄，干燥的速度肯定不一樣，厚的地方表面干了，下面還呈糊狀，厚的地方與薄的地方干燥速度不一樣，就會從厚薄交界處開裂，一旦此時閉水，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.

劃：防水涂料需要分兩遍涂刷，不可一次涂刷過厚導(dǎo)致開裂

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

誤區(qū)四：防水涂料涂刷完24小時就做閉水測試

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，需要進行閉水試驗，一般在竣工48小時后進行。如果未完全固化時進行閉水實驗，易造成防水層起翹、脫落等現(xiàn)象。防水涂料由于化學(xué)反應(yīng)及物理揮發(fā)雙向作用使防水涂料干燥形成具有防水能力致密的涂膜，但是化學(xué)反應(yīng)及物理揮發(fā)均需要過程，當(dāng)兩個過程還未進行完成的時候進行閉水試驗，會使涂膜與基層脫開，起泡等問題。

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.

劃：防水涂料施工后短要過3-4天才能進行閉水試驗

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