In summer, the personality is extreme
.
The ambient temperature for putty construction is within 5-35 ℃, and the air humidity is less than 85% and 10%
.
2
.
Avoid construction in high temperature environment and strong direct sunlight
.
under high-temperature drying environment, the substrate can be sealed with interface agent, or the wall can be wetted with clean water two hours in advance before putty construction, and the putty layer can be cured after it is completely dry; b
.
The correct construction method of putty powder in summer is as follows: 1
.
On the one hand, the temperature soars to a maximum of 40 degrees Celsius, and on the other hand, there is plenty of rainfall
.
As a result, the putty surface dried too fast after construction, resulting in skin curling, powder falling and cracking after scraping
Ensure that the base course is well and firmly treated: the base course is not cracked, powder falling, sand rising, hollowing, peeling, lime bursting point and old coating with poor adhesion; Cleanliness: the surface shall be free of dust, laitance, oil stain, rust, mildew, salt precipitates, moss and other sundries; Leveling: the elevation is vertical, the internal and external corners are vertical, square and free of missing edges and corners, and the depth of dividing joints is consistent, horizontal and vertical
.
We respect originality,
.
Wet environment will also make the strength of water-resistant putty rise faster and the polishing time shorter
.
If the next layer is constructed before the drying of the current layer is completed, it is easy to cause blistering and peeling of the finish layer
.
What are the impacts of improper construction in hot and humid weather in summer, and what is the correct construction method in summer? High temperature exposure, summer exposure, high temperature, not only the substrate is easy to dry and absorb water quickly, but also the strong sunlight will accelerate the water evaporation rate of putty powder
.
The allowable deviation shall meet the requirements and the surface shall be flat and not smooth

The putty powder has been prepared, and it is recommended to use it up immediately; c
.
According to the flatness of wall bottom materials, the putty powder generally needs to be scraped twice or three times
.
Remove the influence of high-temperature drying A
.
It is rainy and humid, but the weather is humid for a long time, the air humidity is too high or the moisture of the base course is large, which will affect the drying speed of the putty
