Putty powder peeling

現(xiàn)象：施工完成及干透后，用手觸摸有掉粉現(xiàn)象。

Phenomenon: After the construction is completed and dried thoroughly, there is a phenomenon of powder falling when touched by hand.

產(chǎn)生原因：

Cause of occurrence:

1、內(nèi)墻膩?zhàn)臃蹝伖鈺r(shí)間掌握不好，表面已經(jīng)干燥后再進(jìn)行拋光處理就會(huì)脫粉；

1. The polishing time of the putty powder on the inner wall is not well controlled. If the surface is dry and then polished, the powder will peel off;

2、外墻膩?zhàn)臃郏椕鏁r(shí)涂層比較薄，在夏天高溫下，水分揮發(fā)很快，面層未能足夠的水分進(jìn)行固化，因而容易脫粉。

2. The exterior wall putty powder has a relatively thin coating when facing, and under high temperatures in summer, the moisture evaporates quickly. The surface layer does not have enough moisture to solidify, making it easy for the powder to peel off.

3、產(chǎn)品超過保質(zhì)期，粘結(jié)力度大幅度下降。

3. The product has exceeded its shelf life and the bonding strength has significantly decreased.

4、產(chǎn)品儲(chǔ)存不當(dāng)，吸潮后粘結(jié)力大幅度下降。

4. Improper storage of the product results in a significant decrease in adhesion after moisture absorption.

5、基層吸水率高，導(dǎo)致膩?zhàn)痈稍锼俣群芸欤瑳]有充足的水分進(jìn)行固化。

5. The high water absorption of the base layer results in a fast drying rate of the putty and insufficient moisture for curing.

解決方法：

Solution:

1、內(nèi)墻膩?zhàn)用鎸訏伖鈺r(shí)要掌握適宜的拋光時(shí)間，拋光的佳時(shí)期就是待膩?zhàn)颖砻嫠∠Ш螅⒓催M(jìn)行拋光。實(shí)踐證明，飾面1~2m2就應(yīng)該進(jìn)行壓平或拋光處理。

1. When polishing the inner wall putty surface layer, it is necessary to grasp the appropriate polishing time. The best polishing period is to immediately polish after the watermark on the putty surface disappears. Practice has shown that the surface area of 1-2 square meters should be flattened or polished.

2、外墻膩?zhàn)颖砻娓稍锖螅M(jìn)行適度打磨，并進(jìn)行充分的淋水保養(yǎng)，一般保養(yǎng)分為兩次或兩次以上進(jìn)行，如果有必要，請(qǐng)用透明封閉底漆兌水（1：5）作為第二道淋水液，效果會(huì)更好。

2. After the surface of the exterior wall putty is dry, it should be moderately polished and thoroughly watered for maintenance. Generally, maintenance is divided into two or more times. If necessary, use a transparent sealing primer mixed with water (1:5) as the second watering solution, which will have a better effect.

3、產(chǎn)品一定要在保質(zhì)期內(nèi)使用，如果超過保質(zhì)期，必須進(jìn)行試刮，經(jīng)檢驗(yàn)合格后，再行施工；

3. The product must be used within the shelf life. If the shelf life is exceeded, a trial scraping must be carried out, and construction can only be carried out after passing the inspection;

4、產(chǎn)品一定要注意防水處理，應(yīng)存在在陰涼干燥處，并且保證包封完好。

4. The product must pay attention to waterproof treatment, should be stored in a cool and dry place, and ensure that the packaging is intact.
