If the wall is painted without drying, it is easy to cause peeling and cracking of the wall.

Summer is a season of frequent typhoons, with strong and frequent winds.
Humidity conditions are equally important for coating construction.
In addition, when hanging putty, wipe the water vapor on the wall with a dry cloth to keep the wall as dry as possible, which is conducive to the painting of the wall.
The overheated weather will dry the coating too fast and affect the final effect.
If it is not preserved properly, it is easy to change the coating performance and cause problems during construction.
Therefore, the paint should be stored in a cool and ventilated place in summer, and the sealing of the storage container must be better.
The temperature is high in summer.
The optimum humidity is 60%.
In summer, the temperature is high and the sun is fierce.
If the wall is difficult to dry due to high temperature, the dehumidifier can be used to accelerate the drying of the wall.

The wall also needs sunscreen and windproof.
The wall is difficult to dry.
Pay attention to the preservation of the coating.

Because the weather in summer is hot and wet, especially when heavy rain comes, the air drying time of putty will be longer.
Low humidity is conducive to coating film formation, but if the humidity is too low, it will lead to too fast solvent volatilization of solvent based coating and too fast drying of water emulsion coating, so that the conjunctiva is not complete and affect the wall effect.
In summer, it is very easy to appear the illusion that “the wall has been completely dry”.
Extend the drying time of wall putty.
When the wall temperature drops after painting, the paint surface will crack.
Apply putty on the wall first, generally 1-3 times, and the normal drying time is 1-2 days.
In terms of coating construction, the temperature is very important for coating construction, because the drying and conjunctive effect of coating depends on the temperature and humidity, and different types of coatings have different film-forming conditions and requirements for temperature.
Generally speaking, the best humidity for coating construction is 60% ~ 70%.
Strong wind will accelerate water evaporation and raise dust, which will affect the film-forming effect and wall cleanliness.
In summer, in addition to high temperature, there is also high humidity.
In summer, the sun is strong, and long-term exposure is easy to lead to the rise of the surface temperature of the base course, so that the water or solvent volatilizes too fast, resulting in unsatisfactory film-forming effect and affecting the quality of the coating.
If the painted wall is often exposed to the sun, it is easy to make the wall color fall off, and the white wall will turn yellow.
Therefore, try to avoid exposure to the sun after painting the wall.
In summer decoration, the time for the putty to dry out shall be extended as much as possible, generally 2-3 days.
The painting of the wall shall avoid rainy days.
During construction, the construction personnel must ensure that the wall base is completely dry before painting the wall paint.
The above introduces some problems that may occur in the construction of wall coating in summer.
It is recommended that the purchased coating be used up within the validity period.
In addition to temperature and humidity, the paint construction should also pay attention to sunscreen and windproof.
The finished wall shall be protected from exposure to the sun.
If possible, the moisture content of the wall should be measured with the help of professional instruments, and the construction can be carried out after reaching the standard.
For our coating construction, high temperature is definitely not a good thing.
What should we pay attention to in the high temperature construction there? Today, let’s talk about the precautions for wall coating construction in summer.
4.
Solvent based coatings should be applied under the temperature of 5 ~ 30 ℃, and water emulsion coatings should be applied under the temperature of 10 ~ 35 ℃.
2.
In summer, the painting of the wall shall not be carried out in high humidity or rainy days.
Before construction, the construction personnel must ensure that the wall base is completely dry before proceeding to the next step.
4.
The illusion that the wall has been completely dry will appear during wall construction in summer.
This is not necessarily a product problem, but a series of problems caused by high temperature.
Now let’s talk about what to pay attention to? 1.
Be careful of the “illusion” of wall dryness.
2.
In addition, exposure will also lead to wall temperature rise.
Cracking and peeling will occur during construction in summer.
Because during construction, the wall foundation is relatively wet and the paint is painted before it is completely dry, the water infiltrates into the paint surface, resulting in the loss of adhesion of the paint film, resulting in the bulge of the wall into a drum shape.
