Water in water and sand in water multicolor coating are well done when making board, but when large-scale construction is carried out on site, color difference and stone like effect will appear, which is why?
The multicolor lacquer imitation stone template is the standard for the first party and the construction unit and the production link when making the imitation stone paint. The quality of the multicolor paint must be systematically considered. The protective glue should be superior, the emulsion should be high quality, the product system should be mature, the design should be reasonable, and the construction must be standardized.
The key to the stability of protective adhesive
Due to the need of production stability, storage stability and construction stability, the protective adhesive plays a very important role in the overall formula. The protective glue must be in harmony with the emulsion and other raw materials, and there is a chemical interaction between them, which ensures that the multicolor paint is not permeable. Toughness, color spots are clear, visible and arbitrary, especially suspension. The suspension of rubber powder can improve the efficiency of granulation in the big water in the sand. As everyone knows, the sand coating is easy to sink after adding sand, and the protective system is suspended in diamond chemical system. It can effectively solve the problem of large-scale production and better guarantee the granulation effect.
Emulsion determines colorful life
As a film forming material of multicolor paint, emulsion plays a decisive role in the performance of coatings, which is directly related to color retention, water resistance, stain resistance, flexibility, weatherability and service life. If the amount of emulsion is low, the product characteristics such as color retention, UV resistance, adhesion and so on will decrease. Otherwise, if the emulsion is excessive, it will appear that the wall is not easy to dry after painting. The multicolor paint is constructed on the exterior wall and must be weatherproof. Therefore, it is suggested to use silicone acrylic emulsion to make water in water and water bag sand coating. The recommended amount of silicone acrylic emulsion is 160 kg -280 kg of the overall formula.

The system is not mature and there are great quality risks
The mature system refers to the combination of various high-quality raw materials in a certain proportion, which can make the construction, waterproof, weather resistance and service life of the products reach the best. Poor stone like effect and unskilled spraying technology will affect the final effect of color. The mature and stable system is mainly obtained by the coating enterprise through repeated field tests and long-term accumulation.
Unreasonable design, easy to contaminate coating
If the color selection or division of multi-color paint is improper, it will not be as awkward as multi-color paint. Scientific and reasonable design scheme can fundamentally ensure the beauty and antifouling of the coating, and improve the quality and grade of the building.
Poor effect of unprofessional finished products
The multi-color paint exterior wall coating system is composed of base course, putty layer, bottom coat, middle coat and surface coat. To ensure the quality of the finished product, each process must be strictly accepted. For example, if the moisture content of the base course is too high, the coating will be hollowed out, and if the alkalinity is too high, the coating will become alkaline and blooming. The putty cannot be applied too thick, and if the primer is missed, the coating will become alkaline. The spraying of the main materials must be made sure that the same batch of materials, the same process, the same thickness, the same time and the same batch of people on the same wall, so as to avoid the phenomenon of color difference and blooming. Any process is inconsistent Lattice can cause quality problems.
In addition, the construction experience of each key node is very important, such as how to avoid splicing in scaffold construction, how to make lines horizontal and vertical, how to avoid joints in internal and external corners, etc.
Ladle sand
The water-based multi-color coating has become the most popular exterior wall high-grade decorative coating, and the demand is rapidly rising. The hot market promotes the rapid expansion of production capacity of multi-color coatings, and various systems emerge in endlessly on the market. The selection of raw materials for multi-color coatings must be strictly controlled, production and construction must be standardized, and ignoring any of them will ultimately affect the quality of the finished products.
Diamond chemical multi-color system, continuous phase and multi-color particles are easy to mix, very suitable for mass production; shear resistant, impermeable color, stable performance; texture and pattern are integrated, one shot molding. Spray resistant, low loss.
