How to break the wall in high temperature in midsummer

Some decoration friends choose to decorate in summer. However, there are some precautions in summer decoration, such as what should I do if the wall decoration encounters high temperature weather? What are the most suitable conditions for construction? How important is the weather for house decoration? These questions were told to you by Bian Xiao.

Paint structure depends on temperature.

Temperature is very important for paint construction, because the drying and conjunctival effect of paint depend on humidity and temperature, and different types of paint have different film forming conditions and temperature requirements. Solvent-based coating should be applied at 5~30℃, and latex paint should be applied at 10~35℃. Too hot weather will make the paint dry too fast, which will affect the final effect.

Optimum humidity 60%

Besides high temperature, there is also high humidity in summer, and humidity conditions are equally important for paint construction. Generally speaking, the optimum humidity for coating construction is 60%~70%. Low humidity is beneficial to film formation, but too low humidity will lead to too fast evaporation of solvent-based coatings and too fast drying of water-emulsion coatings, which will make the conjunctiva incomplete and affect the wall effect.

Sun protection and wind protection

In addition to temperature and humidity, paint construction should also pay attention to sun protection and wind protection. In summer, the sunshine is strong, and long-term exposure can easily lead to the increase of the surface temperature of the base layer, so that the water or solvent evaporates too quickly, resulting in unsatisfactory film-forming effect and affecting the quality of the coating. Summer is a season with frequent typhoons and strong winds. Strong wind will accelerate the evaporation of water and raise dust, which will affect the film-forming effect and the cleanliness of the wall.

Use within one month.

No matter how tight the package is, once it is opened, it is best to use it up within one month. If the seal is not good after opening the cover, it will easily lead to paint pollution and deterioration. The storage environment should be cool and ventilated, away from open flame power supply.

There is an illusion that the wall is dry.

In summer, the wall construction sometimes appears the illusion that the wall is dry. Before construction, the construction personnel must ensure that the wall foundation is completely dry before proceeding to the next construction. If the wall is difficult to dry due to high temperature, a dehumidifier can be used to accelerate the drying of the wall. If the wall is not painted, it will easily lead to peeling and cracking of the wall.

Rain and sun are not suitable.

Wall painting needs to avoid rainy weather and exposure. Rainy weather, heavy water vapor, the wall will be wet. In this weather, the wall construction will cause water vapor to penetrate into the paint surface, resulting in the loss of adhesion of the paint film, and the wall is easy to bulge. After a long period of exposure, the painted wall is easy to yellow and fade. After exposure, the temperature of the wall is high, and after painting, the temperature of the wall is reduced, and the wall is prone to cracks.
