Exterior wall really stone paint colour difference problem why always difficult to solve?

Today, choose really stone paint exterior wall decoration. Exterior wall really stone paint is one of the fastest growing exterior wall coating market, more and more popular in the market. Really stone paint color with natural sand and water-based acrylic emulsion as main raw materials. It's hard to keep different batches of really stone paint color. Next, let's take a look at how to solve the problem of exterior wall really stone paint color difference. 1. 'Sand', the selection of raw material and control is the most fundamental reason of poor really stone paint colour. Natural colour sand are mined from natural colored sand, using artificial crushing equipment, filtered according to the different particle size and the packaging. Due to the different growth period, degree of ore, both inside and outside of sunlight, and other natural factors, in the same area of colored sand ore after crushing processing, the color will be different, some can make a big difference. Different mining area of the same colour colour sand is more difficult to ensure the consistency of color. Mass production color identical really stone paint has a lot of difficulties. At the same time, the feature of natural color to the color of natural colored sand sand downstream of the manufacturer or really stone paint manufacturers also have more stringent requirements. Some large color sand maker when delivery on the downstream production requires the use of mixed mixing equipment, guarantee the consistency of large quantities of color sand color, but the corresponding color sand supply cost will increase, so the color sand and the choice of color sand maker and control as the foundation of control really stone paint colour difference. two 'In the production of color matching technology level' to buy existing really stone paint colour sand, production and research personnel according to customer requirements and the existing sand texture types of color matching. Unlike traditional paint, natural color sand for really stone paint color. Its shape is irregular and uneven coating determines its color was not the major spectrophotometer computer color matching equipment repair, can only rely on color engineer experience of artificial color and repair. The mixed color engineers have relatively strict requirements, such as familiar with raw materials, sensitive to colour experience, accurately mastering really stone paint formula. 3. Really stone paint production control of the production process is according to the formula developed by small sample, and then scale up production, and then modified according to customer requirements. On the production of raw materials feeding method should do it properly, it is a principle with shallow after deep first, first, after more than from the shallow to the deep easy, from deep to shallow. For a small number, color dark colour sand, materials to deduct and complementary methods often can be solved to a large extent color correction repetitions. At the same time, various additives added and adjustment and the process control in the process of production is quite fine. Precise process control and rich production experience, the combination of production and sample color difference is small, high consistency of the necessary conditions for really stone paint. 4. 'True stone' construction method of color also is closely related to the construction method and the thickness. For the same really stone paint or same barrels really stone paint, spraying and the color of the scratches will be slightly different. Spraying really stone paint film of simple sense is strong, uniform dispersion, color uniform dispersion. However, scraping effect is flat, and tend to collect with large particle size of grains of sand. Fine sand is easy to float on the surface, fine sand as the main color. Of course, it depends on the specific construction requirements and coating effects. The thickness of the different colors of paint or scraping also have differences, so construction method should maintain consistency, and as far as possible do construction. Try on the same wall using the same really stone paint. Above is how to solve the Shared KeBao building materials editor really stone paint colour difference problem. If can effectively control the wall really stone paint production and construction, to a large extent can solve the problem of color difference really stone paint. I hope this is helpful to everyone.
