Can a kilogram of real stone paint guarantee the minimum quality? First of all, let's work out an account. At present, the price of color sand with better quality on the market is basically 1.2-2 yuan / kg. If it is a special color, it needs to use high-temperature calcined sand, and the price per kg may be 2.5-3.5 yuan. Plus emulsion, additives, labor and operating costs. To ensure the most basic and minimum quality, the pure raw material cost of real stone paint is more than 3 yuan / kg. So why is there any real stone paint less than 3 yuan / kg in the market? And it also includes certain profits. So, how does the price of real stone paint below 3 yuan / kg come out?
There is only one answer - low price and poor quality raw materials:
1、 Use poor colored sand (0.3-0.5 yuan / kg)
Hardness (silicon content) is the most important basis to measure the quality of colored sand. The better and more expensive the colored sand, the higher the hardness; on the contrary, the worse the colored sand, the lower the hardness. As shown in the figure above, the poor colored sand can be easily crushed and turned into powder by fingers.
The production of real stone paint is a high-speed mixing process. There will be very large friction between the colored sand particles. The poor colored sand has low hardness. In the production process, due to the friction, there will be a large degree of pulverization, and the colored sand will become colored powder. The final coating effect, sand particles are very fuzzy, lack of luster and texture. (as shown above)
High quality colored sand, in the production of high-speed mixing process, due to the high hardness, friction resistance, not easy to powder, the final layer effect, colored sand particles are very clear, full of texture and luster. (as shown above)
If the coating color is bright, only paste can be added for the real stone paint below 3 yuan / kg, because the high-temperature calcined sand with bright color sells for 2.5-3.5 yuan per kg. (the picture above shows the real stone paint with color paste added)
Two. Use differential emulsion.
As the film forming material of genuine lacquer, the quality of emulsion directly determines the performance of the coating. For example (yellowing resistance, water resistance, service life, etc.)
The above is the result of UV resistance test of poor emulsion and high quality emulsion in the laboratory. Poor emulsion, UV resistance is very poor, the sun will soon change after yellowing.
The picture above shows the poor real stone paint, which turns yellow two months after completion.
　
Water resistance is one of the most important indicators of emulsion. Poor emulsion water resistance is very poor, water will appear white.
The above is a comparison of the water resistance test of the genuine lacquer with the difference emulsion and the high quality emulsion.
As shown above, the use of a poor emulsion made of genuine stone paint, once it rains, the water will penetrate into the coating, there is a whitening phenomenon. Water often permeates the coating, which will greatly reduce the service life of the coating.
Three. The emulsion content is very low.
Poor real stone paints, manufacturers in order to reduce costs, the emulsion content is generally relatively low, spraying process spatter, serious waste, resulting in a significant increase in the amount of coating. Generally, the normal amount of real stone paint is 3-4kg per square meter. Due to the serious waste and great loss, the coating amount is often more than 4kg per square meter, some even up to 5kg.
4、 Poor additives
Although the dosage of additives is small, it determines the stability of the whole formulation system.
Poor quality additives, products placed for a certain time, there will be serious stratification. (as shown above)
So, where did such poor real stone paint come from?
?
First of all, we will think of the local small workshops; in fact, in 2014, the real estate industry was deeply adjusted, and the cost control efforts were increased unprecedentedly. In order to participate in the competition, some large-scale comprehensive coating enterprises also began to produce low-quality and low-cost benpropene stone paint.
Cheap behind must be greasy, such as "black cotton" and "gutter oil"! The same is true for the exterior wall stone paint. The lowest price is 100% which can't guarantee the most basic quality. It seems that we control the cost to the minimum, but we sacrifice the external image of the whole building. Unless we don't care about the quality of the exterior wall at all, or what it looks like. If we pay a little attention to the quality, low-cost real stone paint, absolutely can not be used. If our budget is really limited, our advice to you is to use high-quality emulsion paint!
Super low price real stone paint can not be used, so what kind of real stone paint should we choose?
From low to high, the system of real stone paint is: styrene acrylic (low), pure acrylic (medium), silicon acrylic (high), fluorosilicone (advanced customization). For general buildings, at least the middle grade pure acrylic real stone paint should be selected; if the high-grade buildings should choose the silicon acrylic system; for landmark and benchmarking buildings, the fluorine silicon system can be selected. (of course, it is also pure C and silicon C systems, so we must choose professional enterprises. Because the pure acrylic emulsion is also divided into high and low grades, professional brands require very high quality of raw materials, and the stability of the whole formulation system is stronger than that of non professional brands.
Medium and high grade real stone paint is not only the quality of raw materials, but also significantly higher than that of ultra low price genuine stone paint, and the emulsion content is also very high, often 2-3 times of ultra low price products. Whether the product performance, or construction, coating rate, weather resistance, the difference between high-grade and low-grade is very obvious. Many people think that "low-end and high-end, no difference or little difference.". The main reason is that we always choose the ultra-low price styrene acrylic products, and seldom or never use the middle and high-grade real stone paint. If we have used the high-quality real stone paint of pure acrylic and silicon acrylic systems, even if it is a layman, we can see that there are not only differences between them, but also very obvious differences: "good is good, bad is bad"!
As we all know, quality is an important basis to measure the development of an industry. If an industry, all manufacturers are pursuing low price and constantly reducing quality, "the worse the quality is, the worse the industry is", the continuous development will eventually destroy the whole industry. Facing the deep adjustment of the real estate market, it will be difficult for developers and suppliers. If in this period, sacrificing quality and reducing price, life will be more difficult and even eliminated.
We believe that the more difficult it is, the more efforts should be made to enhance value innovation. In the face of rising raw material and labor prices, price reduction and quality reduction can only "sustain for a while", even belong to drinking poison to quench thirst. In order to have a long-term foothold in the industry and promote the future development of the industry to a high level and high value level, we must carry out value innovation. In response to the market downturn and the continuous strengthening of cost control by customers, only innovation is the best way. Because there is no industry that has been in downturn, only the enterprises lost in the market downturn!
　　
In order to highlight their low price advantages, low price real stone paints try to reduce production costs, not only by using poor materials, but also by reducing the amount of emulsion. The original emulsion is poor, the content is further reduced, not only the quality is lowest, but also the construction quality will be reduced to the worst, resulting in the waste of spraying and the slow progress of construction. To verify the above analysis is very simple, directly to their manufacturers on-site inspection, look at their colored sand, emulsion and auxiliaries, to ensure that you see, you fully understand!
