　　济南家里装修、自建房的朋友们，今天跟大家唠个实在话题——家用抹面砂浆的强度怎么选？很多朋友装修时，被商家忽悠，觉得砂浆强度越高越好，盲目选十级以上的高强度砂浆，最后不仅多花了钱，还留下墙面开裂的隐患，得不偿失。其实家用场景，选M5或M7.5强度的济南抹面砂浆就完全够用了，既能满足日常需求，又能避开很多坑，今天就把其中的门道讲透彻，新手也能轻松选对。

　　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.

　　先跟大家说个核心结论：家用抹灰，M5和M7.5强度的抹面砂浆，是最适配、最省心的选择，不用追求更高强度。很多朋友不懂，觉得强度高=质量好，其实不然，砂浆强度的选择，关键看使用场景，家用场景没有那么高的负荷，高强度不仅浪费钱，还会带来额外隐患，咱们一步步慢慢唠。

　　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.

　　先说说M5强度的抹面砂浆，这是家用最常用、性价比最高的一款，完全能满足大多数日常装修需求。它的强度不算高，但足够应对家用场景，尤其是济南家庭室内干燥的墙面，比如客厅、卧室、书房的墙面找平、打底，还有一些异形墙面的抹灰，用M5强度的砂浆都特别合适。

　　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.

　　可能有朋友会担心，M5强度会不会太低，不耐用？大家完全放心，家用墙面大多只是起到找平、打底的作用，后续还要刷乳胶漆、贴壁纸，不需要承受太大重量，M5的强度完全够用。而且它还有一个很大的优势，就是施工方便，和易性好，抹灰的时候容易摊抹、找平，哪怕是新手师傅施工，也能做出平整的墙面，不会出现起砂、脱落的情况。

　　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强度的砂浆，能有效避免因强度过高导致的墙面开裂。很多朋友选了高强度砂浆，后期墙面很容易出现裂纹，就是因为砂浆刚性太强，和墙体变形不协调，温度变化、墙体轻微沉降时，就会产生裂缝，反而影响装修效果，而M5强度适中，柔韧性更好，能减少开裂风险，住着更省心。

　　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.

　　再说说M7.5强度的抹面砂浆，它比M5强度稍高一些，适配的场景更有针对性，适合家里一些特殊区域使用。比如厨房、卫生间这些潮湿区域，墙面长期处于潮湿环境，对砂浆的粘结性、耐久性要求更高，这时候选M7.5强度的就很合适，它的粘结性更强，不容易出现返潮、起鼓、脱落的情况，能更好地适应潮湿环境。

　　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，家里如果有墙面需要虚挂重物，比如墙面要挂吊柜、置物架，或者电视背景墙需要挂电视，这些区域的墙面抹灰，也建议选M7.5强度的抹面砂浆。因为这些区域需要承受一定的重量，M7.5的强度更高，粘结性和耐久性更优，能牢牢固定住重物，避免后期出现墙面松动、重物脱落的安全隐患，用着更放心。

　　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.

　　这里必须提醒济南的朋友们，家用抹面砂浆，完全不需要选十级以上的高强度款。很多商家为了多赚钱，会忽悠大家选高强度砂浆，说强度越高越耐用，但实际上，家用场景根本用不上这么高的强度，高强度砂浆不仅原材料成本高，售价更贵，会增加装修预算，而且还有一个致命缺点——刚性过强。

　　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.

　　咱们家里的墙体，难免会有轻微的沉降、变形，尤其是自建房的墙体，后期可能会有细微的位移，而高强度砂浆刚性太强，没有足够的柔韧性，无法适应墙体的轻微变形，很容易出现墙面开裂的情况，一旦开裂，后期修复起来特别麻烦，既费钱又费力，反而得不偿失。

　　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.

　　可能有朋友会问，怎么区分M5和M7.5强度的济南抹面砂浆，避免被商家以次充好？其实很简单，买的时候，一定要认准包装上的强度标注，正规的抹面砂浆，包装上都会清晰标注“M5”或“M7.5”字样，同时要索要相关的检测报告，确认强度达标，不要买没有标注、来路不明的砂浆。

　　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.

　　还有一点，济南的朋友们装修时，要根据自家的实际场景选择：室内干燥区域，比如客厅、卧室，选M5就够了，性价比高、施工方便；厨房、卫生间等潮湿区域，或者需要挂重物的墙面，选M7.5，粘结性、耐久性更有保障。不用盲目追求高强度，适合自己家的，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.

　　总结一下，家用济南抹面砂浆的选择，核心就是“适配”二字，M5和M7.5才是家用刚需，完全能满足日常装修需求。选对强度，不仅能节省装修成本，还能避免后期墙面开裂、脱落等隐患，住着更省心。希望今天的分享，能帮到济南正在装修、自建房的朋友们，避开砂浆选择的坑，选到合适的抹面砂浆，让装修更顺利、住着更放心。

　　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.
