　　How to choose Jinan household plastering mortar? M5 and M7.5 are essential, don't waste money unnecessarily

　　濟南家里裝修、自建房的朋友們，今天跟大家嘮個實在話題——家用抹面砂漿的強度怎么選？很多朋友裝修時，被商家忽悠，覺得砂漿強度越高越好，盲目選十級以上的高強度砂漿，最后不僅多花了錢，還留下墻面開裂的隱患，得不償失。其實家用場景，選M5或M7.5強度的濟南抹面砂漿就完全夠用了，既能滿足日常需求，又能避開很多坑，今天就把其中的門道講透徹，新手也能輕松選對。

　　For friends who decorate and build their own houses in Jinan, today we will talk about a practical topic - how to choose the strength of household plastering mortar? Many friends are deceived by businesses when decorating, thinking that the higher the strength of the mortar, the better. They blindly choose high-strength mortar with a grade of ten or above, which not only costs more, but also leaves the hidden danger of wall cracking, which is not worth the loss. In fact, for home use scenarios, choosing M5 or M7.5 strength Jinan plaster mortar is completely sufficient, which can meet daily needs and avoid many pitfalls. Today, we will explain the tricks in detail, and beginners can easily choose the right one.

　　先跟大家說個核心結論：家用抹灰，M5和M7.5強度的抹面砂漿，是最適配、最省心的選擇，不用追求更高強度。很多朋友不懂，覺得強度高=質量好，其實不然，砂漿強度的選擇，關鍵看使用場景，家用場景沒有那么高的負荷，高強度不僅浪費錢，還會帶來額外隱患，咱們一步步慢慢嘮。

　　First of all, let me share a core conclusion with you: for household plastering, M5 and M7.5 strength plastering mortar are the most suitable and worry free choices, without the need to pursue higher strength. Many friends don't understand, thinking that high strength equals good quality. In fact, the choice of mortar strength depends on the usage scenario. Household scenarios don't have such high loads, and high strength not only wastes money but also brings additional hidden dangers. Let's talk about it step by step.

　　先說說M5強度的抹面砂漿，這是家用最常用、性價比最高的一款，完全能滿足大多數日常裝修需求。它的強度不算高，但足夠應對家用場景，尤其是濟南家庭室內干燥的墻面，比如客廳、臥室、書房的墻面找平、打底，還有一些異形墻面的抹灰，用M5強度的砂漿都特別合適。

　　Let's first talk about M5 strength plastering mortar, which is the most commonly used and cost-effective option for household use, and can fully meet most daily decoration needs. Its strength is not high, but it is sufficient to cope with household scenarios, especially for dry indoor walls in Jinan households, such as leveling and priming walls in living rooms, bedrooms, and study rooms, as well as plastering some irregular walls. M5 strength mortar is particularly suitable.

　　可能有朋友會擔心，M5強度會不會太低，不耐用？大家完全放心，家用墻面大多只是起到找平、打底的作用，后續還要刷乳膠漆、貼壁紙，不需要承受太大重量，M5的強度完全夠用。而且它還有一個很大的優勢，就是施工方便，和易性好，抹灰的時候容易攤抹、找平，哪怕是新手師傅施工，也能做出平整的墻面，不會出現起砂、脫落的情況。

　　Some friends may be worried that the M5 strength may be too low and not durable? Everyone can rest assured that most household walls only serve as leveling and base, and later need to be painted with latex paint and wallpaper. They do not need to bear too much weight, and the strength of M5 is completely sufficient. And it also has a great advantage, which is convenient construction and good workability. When plastering, it is easy to spread and level. Even novice craftsmen can make smooth walls without sanding or peeling.

　　更重要的是，M5強度的砂漿，能有效避免因強度過高導致的墻面開裂。很多朋友選了高強度砂漿，后期墻面很容易出現裂紋，就是因為砂漿剛性太強，和墻體變形不協調，溫度變化、墻體輕微沉降時，就會產生裂縫，反而影響裝修效果，而M5強度適中，柔韌性更好，能減少開裂風險，住著更省心。

　　More importantly, M5 strength mortar can effectively prevent wall cracking caused by excessive strength. Many friends choose high-strength mortar, which can easily cause cracks on the wall in the later stage. This is because the mortar has too strong rigidity and is not coordinated with the deformation of the wall. When the temperature changes or the wall slightly settles, cracks will occur, which will affect the decoration effect. M5 has moderate strength and better flexibility, which can reduce the risk of cracking and make living more worry free.

　　再說說M7.5強度的抹面砂漿，它比M5強度稍高一些，適配的場景更有針對性，適合家里一些特殊區域使用。比如廚房、衛生間這些潮濕區域，墻面長期處于潮濕環境，對砂漿的粘結性、耐久性要求更高，這時候選M7.5強度的就很合適，它的粘結性更強，不容易出現返潮、起鼓、脫落的情況，能更好地適應潮濕環境。

　　Speaking of M7.5 strength plastering mortar, it has slightly higher strength than M5 and is more targeted for specific scenarios, making it suitable for use in special areas of the home. For example, in damp areas such as kitchens and bathrooms, where the walls are exposed to moisture for a long time, higher requirements are placed on the bonding and durability of mortar. At this time, choosing M7.5 strength is very suitable, as it has stronger bonding and is less prone to moisture regain, bulging, and peeling, making it better suited for damp environments.

　　另外，家里如果有墻面需要虛掛重物，比如墻面要掛吊柜、置物架，或者電視背景墻需要掛電視，這些區域的墻面抹灰，也建議選M7.5強度的抹面砂漿。因為這些區域需要承受一定的重量，M7.5的強度更高，粘結性和耐久性更優，能牢牢固定住重物，避免后期出現墻面松動、重物脫落的安全隱患，用著更放心。

　　In addition, if there are walls in the home that require hanging heavy objects, such as hanging cabinets or shelves, or TV background walls that require hanging TVs, it is recommended to use M7.5 strength plaster mortar for wall plastering in these areas. Because these areas need to bear a certain amount of weight, M7.5 has higher strength, better adhesion and durability, and can firmly fix heavy objects, avoiding safety hazards such as wall looseness and heavy object detachment in the later stage, making it more reassuring to use.

　　這里必須提醒濟南的朋友們，家用抹面砂漿，完全不需要選十級以上的高強度款。很多商家為了多賺錢，會忽悠大家選高強度砂漿，說強度越高越耐用，但實際上，家用場景根本用不上這么高的強度，高強度砂漿不僅原材料成本高，售價更貴，會增加裝修預算，而且還有一個致命缺點——剛性過強。

　　It is necessary to remind friends in Jinan that there is no need to choose high-strength products with a grade of ten or above for household plastering mortar. Many businesses, in order to make more money, will deceive people into choosing high-strength mortar, saying that the higher the strength, the more durable it is. However, in reality, such high strength is not necessary for household use. High strength mortar not only has high raw material costs and higher prices, which will increase decoration budgets, but also has a fatal disadvantage - excessive rigidity.

　　咱們家里的墻體，難免會有輕微的沉降、變形，尤其是自建房的墻體，后期可能會有細微的位移，而高強度砂漿剛性太強，沒有足夠的柔韌性，無法適應墻體的輕微變形，很容易出現墻面開裂的情況，一旦開裂，后期修復起來特別麻煩，既費錢又費力，反而得不償失。

　　The walls in our home are inevitably subject to slight settlement and deformation, especially those built by ourselves. There may be slight displacement in the later stage, and high-strength mortar has too strong rigidity and insufficient flexibility to adapt to the slight deformation of the walls. It is easy to cause wall cracking, and once it cracks, it is particularly difficult to repair in the later stage, which is both expensive and laborious, and not worth the loss.

　　可能有朋友會問，怎么區分M5和M7.5強度的濟南抹面砂漿，避免被商家以次充好？其實很簡單，買的時候，一定要認準包裝上的強度標注，正規的抹面砂漿，包裝上都會清晰標注“M5”或“M7.5”字樣，同時要索要相關的檢測報告，確認強度達標，不要買沒有標注、來路不明的砂漿。

　　Some friends may ask, how to distinguish between M5 and M7.5 strength Jinan plaster mortar to avoid being sold as inferior by merchants? It's actually very simple. When buying, be sure to pay attention to the strength label on the packaging. Regular plastering mortar will be clearly labeled with the words "M5" or "M7.5" on the packaging. At the same time, you need to request relevant testing reports to confirm that the strength meets the standard. Do not buy mortar without labels or unknown sources.

　　還有一點，濟南的朋友們裝修時，要根據自家的實際場景選擇：室內干燥區域，比如客廳、臥室，選M5就夠了，性價比高、施工方便；廚房、衛生間等潮濕區域，或者需要掛重物的墻面，選M7.5，粘結性、耐久性更有保障。不用盲目追求高強度，適合自己家的，才是最好的。

　　One more thing, friends in Jinan should choose according to their actual scene when decorating: for indoor dry areas such as living rooms and bedrooms, choosing M5 is enough, with high cost-effectiveness and convenient construction; For damp areas such as kitchens and bathrooms, or walls that require hanging heavy objects, choose M7.5 for better adhesion and durability. Don't blindly pursue high intensity, what suits your own home is the best.

　　總結一下，家用濟南抹面砂漿的選擇，核心就是“適配”二字，M5和M7.5才是家用剛需，完全能滿足日常裝修需求。選對強度，不僅能節省裝修成本，還能避免后期墻面開裂、脫落等隱患，住著更省心。希望今天的分享，能幫到濟南正在裝修、自建房的朋友們，避開砂漿選擇的坑，選到合適的抹面砂漿，讓裝修更順利、住著更放心。

　　To sum up, the core of choosing Jinan plastering mortar for household use is the word "adaptation". M5 and M7.5 are essential for household use and can fully meet daily decoration needs. Choosing the right strength can not only save decoration costs, but also avoid hidden dangers such as wall cracking and peeling in the later stage, making living more worry free. I hope today's sharing can help friends in Jinan who are renovating or building their own houses to avoid the pitfalls of mortar selection and choose the appropriate plastering mortar, making the decoration smoother and living more reassuring.
