In wall decoration construction, putty powder is the basic material for creating a flat wall, especially for exterior wall putty. It not only needs to ensure flatness, but also withstand the erosion of wind and sun. But many construction workers and owners have encountered a headache problem - dense bubbles appear just after the exterior wall putty is applied, which not only affects the appearance, but also reduces the adhesion of the putty, and is prone to cracking and falling off in the later stage. In fact, the foaming of exterior wall putty is not accidental, but mostly related to improper construction operations or material ratios. Today, we will specifically popularize knowledge related to putty powder, focusing on dismantling the 5 core reasons for the foaming of exterior wall putty, to help everyone avoid construction pits.
第一個(gè)常見原因是膩?zhàn)訑嚢璨痪鶆颉:芏嗳藞D省事,攪拌時(shí)敷衍了事,導(dǎo)致膩?zhàn)臃酆退疀]有充分融合,內(nèi)部結(jié)構(gòu)雜亂無(wú)章。這樣的膩?zhàn)优蔚綁γ嫔虾螅S著水分逐漸蒸發(fā),內(nèi)部不均勻的間隙會(huì)形成空氣腔,最終頂起膩?zhàn)訉樱纬蓺馀荨S绕渫鈮κ┕きh(huán)境復(fù)雜,攪拌不勻的膩?zhàn)雍罄m(xù)還可能因結(jié)構(gòu)不穩(wěn)定,加劇破損問(wèn)題。
The first common reason is uneven mixing of putty. Many people try to save time by mixing hastily, resulting in incomplete fusion of putty powder and water, and a chaotic internal structure. After scraping such putty onto the wall, as the moisture gradually evaporates, uneven gaps inside will form air pockets, ultimately lifting the putty layer and forming bubbles. Especially in the complex construction environment of exterior walls, uneven mixing of putty may further exacerbate damage problems due to structural instability.
第二個(gè)原因是膩?zhàn)蛹铀窟^(guò)多。不少施工人員覺得加水多的膩?zhàn)痈门危瑓s忽略了水量對(duì)膩?zhàn)有阅艿挠绊憽<铀^(guò)多會(huì)讓膩?zhàn)舆^(guò)于濕潤(rùn),內(nèi)部水分蒸發(fā)時(shí)會(huì)帶動(dòng)空氣流動(dòng),而過(guò)多的水分又會(huì)阻礙空氣排出,最終形成氣泡。這里給大家一個(gè)明確的參考:一般外墻膩?zhàn)拥募铀拷ㄗh控制在10%到20%之間,具體可根據(jù)膩?zhàn)臃鄣漠a(chǎn)品說(shuō)明微調(diào),既保證施工流暢性,又能避免氣泡產(chǎn)生。
The second reason is that there is too much water added to the putty. Many construction workers think that putty with more water is better for scraping, but they overlook the influence of water on the performance of putty. Adding too much water will make the putty too wet, and when the internal moisture evaporates, it will drive air flow. However, excessive moisture will hinder air discharge, ultimately forming bubbles. Here is a clear reference for everyone: it is recommended to control the amount of water added to exterior wall putty between 10% and 20%. Specific adjustments can be made according to the product instructions of the putty powder to ensure smooth construction and avoid the generation of bubbles.
基層處理不當(dāng),也是外墻膩?zhàn)悠鹋莸闹匾T因。外墻基層長(zhǎng)期暴露在室外,容易積累灰塵、油污,或存在松散的表層。如果施工前沒有對(duì)基層進(jìn)行充分的清潔和打磨,膩?zhàn)泳蜔o(wú)法和基層緊密貼合,兩者之間會(huì)殘留空氣和雜質(zhì)。后續(xù)隨著環(huán)境溫濕度變化,這些殘留的空氣會(huì)膨脹,導(dǎo)致膩?zhàn)訉悠鹋荨K酝鈮κ┕で埃欢ㄒ鸦鶎忧謇砀蓛簦匾獣r(shí)進(jìn)行打磨處理,提升膩?zhàn)拥母街Α?/p>
Improper grassroots treatment is also an important cause of foam formation in exterior wall putty. The base layer of the exterior wall is exposed to the outside for a long time, which can easily accumulate dust, oil stains, or have a loose surface. If the base layer is not thoroughly cleaned and polished before construction, the putty cannot be tightly adhered to the base layer, and air and impurities will remain between the two. Subsequently, with changes in environmental temperature and humidity, these residual air will expand, causing the putty layer to bubble. So before the construction of the exterior wall, it is necessary to clean the base layer and polish it if necessary to improve the adhesion of the putty.
第四個(gè)原因是單層批刮過(guò)厚。有些人為了節(jié)省工期,想一次性完成找平,把膩?zhàn)优蔚煤芎瘛5@樣做會(huì)讓膩?zhàn)訉觾?nèi)部的空氣難以順利排出,隨著水分蒸發(fā),空氣被封在內(nèi)部,就會(huì)形成氣泡。正確的做法是分批次薄批,建議批刮兩到三層,而且每層之間必須等上一層完全干燥后再進(jìn)行,這樣能讓空氣充分揮發(fā),避免氣泡和開裂問(wèn)題。
The fourth reason is that the single-layer scraping is too thick. Some people, in order to save time, want to complete leveling in one go by scraping the putty very thick. But doing so will make it difficult for the air inside the putty layer to be discharged smoothly. As the moisture evaporates, the air is sealed inside, forming bubbles. The correct approach is to divide the batch into thin batches. It is recommended to scrape two to three layers, and wait for the previous layer to completely dry before proceeding. This can allow the air to evaporate fully and avoid problems such as bubbles and cracking.
最后一個(gè)容易被忽略的原因,是膩?zhàn)又欣w維素添加量過(guò)大。纖維素能提升膩?zhàn)拥娜犴g性和保水性,但添加過(guò)多反而會(huì)適得其反,讓膩?zhàn)觾?nèi)部結(jié)構(gòu)變得過(guò)于松散。這樣的膩?zhàn)訌?qiáng)度不足,內(nèi)部間隙多,空氣容易積聚,施工后很容易出現(xiàn)起泡現(xiàn)象。根據(jù)行業(yè)經(jīng)驗(yàn),纖維素的添加量建議控制在2%到6%之間,才能保證膩?zhàn)拥恼P阅堋?/p>
The last easily overlooked reason is the excessive amount of cellulose added to the putty. Cellulose can improve the flexibility and water retention of putty, but adding too much can have the opposite effect, making the internal structure of putty too loose. This type of putty has insufficient strength, multiple internal gaps, and is prone to air accumulation, making it easy to produce bubbles after construction. Based on industry experience, it is recommended to control the amount of cellulose added between 2% and 6% to ensure the normal performance of putty.
其實(shí)外墻膩?zhàn)悠鹋輪?wèn)題,大多可以通過(guò)規(guī)范操作避免。從均勻攪拌、控制加水量,到做好基層處理、分層薄批,再到合理控制材料配比,每一個(gè)環(huán)節(jié)都不能馬虎。希望通過(guò)這次科普,能讓大家更了解膩?zhàn)臃鄣氖┕ひc(diǎn),在后續(xù)外墻裝修中避開這些常見問(wèn)題,打造出平整、耐用的墻面。如果大家在膩?zhàn)臃凼褂没蛏皾{施工中還有其他疑問(wèn),也可以多關(guān)注相關(guān)施工規(guī)范,或向?qū)I(yè)人士咨詢。
In fact, the problem of foam formation in exterior wall putty can mostly be avoided through standardized operations. From uniform mixing and controlling the amount of water added, to well treating the base layer, layering and thinning the batch, to reasonably controlling the material ratio, every step cannot be taken lightly. I hope that through this science popularization, everyone can have a better understanding of the construction points of putty powder, avoid these common problems in subsequent exterior wall decoration, and create smooth and durable walls. If you have any other questions about the use of putty powder or mortar construction, you can also pay more attention to relevant construction specifications or consult professionals.
