There is an old saying in the painting industry: â€œThree sides, seven ends.â€ Means that the role of surface materials only accounts for 30% of the quality, while the role of the grass-roots materials accounted for 70%. In general, the role of grass-roots materials is mainly strong, smooth and smooth. On this basis, the role played by the surface layer material is mainly â€œcoloringâ€, that is, imparting surface color and playing a role in beautifying and decorating.
If the grass-roots level is very good, even if the surface layer is made of mid-range materials, it will be similar to high-grade painting. On the contrary, if the grass-roots level is poor, even if the surface layer is high-grade material, only middle and low-grade paintings can be made. Therefore, when decorating homes, it is more important to choose high-quality putty besides choosing the finish. What kind of putty can be considered as high quality putty?
First, firmly bonded
At present, most of the decoration companies are still using the original method to prepare putty. The putty that is prepared by this method is prone to inaccurate proportions, inaccurate measurements, poor adhesion, and is prone to flaking and shedding.
Second, smooth and delicate
In general, the coating formed after the film is formed has a thickness of only a few tens of wires, and the smoothness of the putty layer directly determines the smoothness of the coating surface.
Third, good water resistance
Water resistance is often an important factor in determining the quality of putty. Good water resistance putty not only has good adhesion under moldy and damp conditions, but also has a great help in the film formation on the surface of the paint.
Base surface treatment:
1. New wall: Make sure that all dust foreign matter is brushed or scraped off. It is also necessary to ensure that the walls are free of saline, greasy materials and ridges. Cover all adjacent walls during construction to avoid being sprayed. All cracks and flaking should be caulked and leveled. Before the official application, it is recommended to seal it with anti-mite primer.
2. Old wall: This product is applied to the old wall and it must be ensured that the wall base is firm. When applying the first coat, first wash the wall with a soda solution, brush it, and apply it after drying.
Note: For more complex foundation construction, in order to ensure the best results, it is best to coordinate with the coating supplier and design the corresponding construction plan according to the actual situation.
Construction method: When spraying is completed by the spray gun and the compressor, it is ensured that the coating is not covered in advance. Roller coating consists of decorative roller series to complete various texture patterns. The product can be applied to the wall with a steel trowel, and the final pattern effect can be achieved with a soaked glossy plastic roller or a plastic trowel.
Construction Environment: The suitable construction temperature is 5-40 degrees Celsius, and the humidity requirement is 90% or less. When sprayed, the wind speed should be less than 6m/s, and the air compressor should be supplied with more than 6kg.
Product features: Use knife, roller or spray gun tool to smooth or texture effect products. Rich in texture, long-lasting, color-preserving finish.
