How to solve common problems in colorful paint construction?

Water-in-water whitening

After the main material is applied, it is fully dried and then coated
.
The top coat should be of good quality and don't save materials
.
These can all improve this problem, but in the final analysis, it is a material problem
.
This problem can be solved by working hard on the main material .

Cracking problem

Although the water-based colorful paint has anti-cracking properties, it cannot be used alone to achieve a decorative effect.
It is necessary to adopt a series of reasonable construction techniques on the wall, such as choosing a leveling mortar with excellent crack resistance and resistance to cracking.
reinforcing base material, alkali primer, intermediate coat weather resistance and the like
.

Construction equipment problems

Because the water-based colorful paint has certain corrosiveness and adhesion to the coating equipment, especially the iron equipment has a certain rust effect, it is easy to dissolve the metal in the transportation pipeline, cause the dispersed particles to precipitate, and the coating film produces pitting; and water Water-in-water colorful paint has poor dispersion stability against strong mechanical forces.
When the flow velocity in the conveying pipeline changes sharply, the dispersed particles are compressed into solid particles, causing pitting in the coating film
.

Stabilization problem

Because the water content of the water-based colorful paint is relatively high, and the volatilization of water strongly depends on the environment.
In a low humidity environment, it may dry quickly and sometimes cause cracks; in a high humidity environment, the film formation process will be very slow.
It is easy to cause the paint to sag; in addition, the newly formed paint layer is often very sensitive to water, and the increase of water vapor content in the air will cause the paint to wrinkle
.

Storage problem

Since the water-based multi-color paint is composed of a dispersed phase and a continuous phase, the two phases are relatively insoluble to form a water-in-water multi-color paint product
.
However, due to the difference in the proportion of the two or the improper control of the system viscosity, the dispersed phase sinks and the continuous phase floats during long-term storage, resulting in a floating water layer after storage of the water-based colorful paint
