What should be paid attention to in exterior wall coating construction

When constructing exterior wall coating, we should pay attention to the following points to ensure the coating quality.

Influence of construction temperature

Generally, the latex paint in the exterior wall coating needs to be above 5℃ before construction, and a small amount needs to be above 10℃. In the cold winter, only a high temperature at noon can meet the construction requirements of exterior wall coatings, but the temperature will drop sooner or later, so the construction workers do not pay attention to adjusting the construction time in time, which will show that the coating film of some construction walls is not well formed.

Avoid water saturation.

To avoid moisture on the north side of the coating. Such as bathroom, toilet, etc. Waterproof sealing layer should be made on the indoor wall, otherwise the paint on the front of the external wall will be simply powdered, frosted, blistered or polluted, which will seriously affect the decoration effect.

Influence of construction humidity

The influence of construction humidity on exterior wall coating construction is often ignored by many construction teams, but when the humidity is more than 85% or the wall is still wet after rain, exterior wall coating construction cannot be carried out.

Influence of basic treatment

In the construction of exterior wall coatings, in addition to the construction humidity, the bottom treatment will also be one of the problems that are simply ignored. Low-strength putty is widely used, which affects the coating quality and eventually damages the whole coating.
