Solution: When the base layer is too dry, it should be moisturized during construction, avoiding high temperature periods such as noon. For the putty powder that has been peeled and scraped in batches, the putty powder should be removed and scraped again.

Reason: In summer, the temperature is high, and the base layer is too dry, causing the putty powder to dry quickly, resulting in bubbles.

Solution: When mixing putty powder, it should be thoroughly mixed as required and constructed within the appropriate temperature range. If there are bubbles in the putty powder during batch scraping, it can be repeatedly compressed while the surface is dry to eliminate the bubbles.

After the construction is completed and dried thoroughly, there is a phenomenon of powder falling when touched by hand, and in severe cases, there may even be peeling between the two layers of putty powder or between the putty powder and the substrate.

原因：膩?zhàn)臃墼诟邷馗稍飼r(shí)施工，水分揮發(fā)快，沒(méi)有足夠水分進(jìn)行固化，因而容易脫粉。而底層膩?zhàn)臃凼杷煞刍瘒?yán)重，面層膩?zhàn)臃厶玻稍锾鞎?huì)造成脫層。另外,外墻膩?zhàn)臃郾挥晁疀_刷后，粘結(jié)劑流失，重批后也容易脫層。

Reason: Putty powder is applied at high temperatures and dryness, causing rapid moisture evaporation and insufficient moisture for solidification, making it easy to peel off the powder. And the bottom layer putty powder is loose and severely powdery, while the surface layer putty powder is too hard and dries too quickly, which can cause delamination. In addition, after the external wall putty powder is washed away by rainwater, the adhesive is lost, and it is also easy to delaminate after re approval.
