In summer, the weather is generally hot and the temperature is relatively high. But some people also choose to decorate their houses in the summer. House decoration in summer is not only a great challenge to the physical strength of decoration workers, but also a big problem to the decoration materials, especially putty. So summer decoration, putty powder prone to what problems? Jinan putty powder manufacturers summarized three main problems.

问题一：干得快

Problem 1: fast work

腻子粉料在桶里调配时干的很快，难施工，批刮后失水快，不能正常收压或施工后干燥过快。

The putty powder dries very fast when it is mixed in the bucket, so it is difficult to construct. It loses water quickly after scraping. It can't be compressed normally or dried too fast after construction.

原因：施工环境气温太高，湿度太低、通风太强及阳光直晒，腻子中的复合材料反应加速。

Reasons: the temperature of construction environment is too high, the humidity is too low, the ventilation is too strong and the sunlight is direct, and the reaction of composite materials in putty is accelerated.

解决方案：预防为主，注意施工环境，避免在高温时段、阳光直晒时段施工，控制施工场地通风强度。当基面出现太过干燥、 吸水快的情况时建议刷涂界面剂或者预先湿润基面(但不能有明水)再施工。

Solution: prevention first, pay attention to the construction environment, avoid construction in high temperature period and direct sunlight period, and control the ventilation intensity of the construction site. When the base surface is too dry and absorbs water quickly, it is recommended to brush the interface agent or wet the base surface in advance (but there is no open water) before construction.

问题二：掉粉、 脱层

Problem 2: powder falling and delamination

施工完成及干透后，用手触摸有掉粉现象，严重的甚至出现前后两道腻子之间或腻子与基底之间相互剥离。

After the construction is completed and dried thoroughly, there is powder dropping phenomenon when touching with hands. In serious cases, there is even peeling between the front and back putty or between the putty and the base.

原因：腻子在高温干燥时施工，水分挥发快，没有足够水分进行固化，因而容易脱粉。而底层腻子疏松粉化严重，面层腻子太硬，干燥太快会造成脱层。另外,外墙腻子被雨水冲刷后，粘结剂流失，重批后也容易脱层。

Reason: Putty in high temperature dry construction, moisture volatilization fast, not enough moisture for curing, so easy to powder. The bottom layer putty is loose and powdered seriously, the surface layer putty is too hard, drying too fast will cause delamination. In addition, after the external wall putty is washed by rain, the binder is lost, and it is easy to peel off after re approval.

解决方案：高温、干燥强风天气施工，更好将基面润湿无明水后再进行腻子施工。施工时要收压密实，适度掌握干燥时间。处理起来具体情况具体分析:

Solution: high temperature, dry and windy weather construction, it is best to wet the base surface without water before putty construction. During the construction, the pressure should be collected and compacted, and the drying time should be controlled appropriately. The specific situation is analyzed in detail

1、内墙耐水腻子涂过封闭底漆后，强度会增加，一般无需另行处理。

1. The strength of water-resistant putty for interior wall will increase after being coated with sealing primer, so it does not need to be treated separately.

2、外墙腻子应严格执行保湿施工，避免阳光直射施工，面层腻子表干后及时适度打磨并充分淋水2次以上。

2. The external wall putty shall strictly implement the moisturizing construction to avoid direct sunlight construction. After the surface layer putty is dry, it shall be timely and moderately polished and fully watered for more than 2 times.

3、压光腻子表面应再薄批腻子一道，并及时进行压光处理。

3. The surface of calendered putty shall be applied with a thin layer of putty and calendered in time.

问题三：开裂

Problem 3: cracking

腻子层产生裂缝，开裂分为有规则线状裂、“T型裂”、 网状裂”、大的龟裂、不规则短线状裂、局部小龟裂、阴角同时有较多垂直短线裂等。

The cracks in the putty layer can be divided into regular linear cracks, "T-shaped cracks", reticular cracks, large cracks, irregular short linear cracks, local small cracks, and many vertical short linear cracks in the internal corner.

原因：单遍批刮太厚，干燥太快，表干里不干，当然裂纹有多种，主要有以下几种。

Reason: single pass batch scraping is too thick, drying is too fast, surface drying is not dry, of course, there are many kinds of cracks, mainly the following.

1、有规则线状裂主要是裂缝处开裂。

1. The regular linear crack is mainly at the crack.

2、“T型裂”、“网状裂”主要是基层开裂。

2. The "T-type crack" and "network crack" are mainly the base crack.

3、大的龟裂及不规则较短线状裂纹是腻子批刮太厚的干裂。

3. Large cracks and irregular short linear cracks are dry cracks of too thick putty.

4、阴角裂同时有较多垂直短线裂主要是基层太松或修角腻子太硬、太厚。

4. At the same time, there are many vertical short line cracks in internal corner cracks, mainly because the base is too loose or the corner putty is too hard or too thick.

解决方案：腻子严重开裂需要铲掉后重批；结构松动要待结构稳定后施工；接缝开裂应该预先做好接缝处理再批刮腻子。

Solutions: serious cracks of putty need to be removed and re approved; structural looseness needs to be constructed after the structure is stable; joint cracking should be treated in advance before putty is applied.

因为夏季温度高风大，所以，夏季批腻子，主要是解决好防晒、防风这两个问题，当然高温季节施工，工人防中暑的工作也要做好。

Because of the high temperature and strong wind in summer, the main purpose of applying putty in summer is to solve the two problems of sun protection and wind protection. Of course, workers should also do a good job in heatstroke prevention during construction in high temperature season.
