First, the benefits of granite coatings
1, which is made of mica flakes and other aggregates, additives and water. It becomes simple spraying or batch coating, and forms a coating on the building surface that looks like natural granite stone.
2, convenient installation and construction, strong texture, looks like granite, good toughness, and can also prevent cracking, which will fade after a period of use.
3. The granite coating has good stability, and various materials in the granite coating are evenly mixed, which is easy to be constructed in a large area for a long time without color difference.
4. It is very important to match the color, size and quantity of granite coating, so it must be prepared with reference to natural granite.
5. Granite coating is a kind of resin base material, which makes the multilayer coating film have high strength, high wear resistance and brushing resistance, as well as high ductility and crack resistance.
6, high self-cleaning characteristics, so that the coating surface is always as new, and has anti-pollution and scrub resistance characteristics, even if it is polluted, it can be easily removed by water-based detergent.
7. Wear resistance and boiling water resistance, high elongation and warpage resistance, and it is also an excellent waterproof decorative surface material. Water-borne granite coating has stable particle structure, good storage, long-term storage and unchanged color.
Second, the granite coating matters needing attention
1. Granite coating is hard on the outside, and nails can't trace it. Under normal weather, nails can still be traced out after three days, indicating that the exterior wall paint is soft, probably because the selected emulsion is not suitable. It is completely wrong to produce latex paint emulsion for granite coatings in many places. In the formula of granite coating, the emulsion content is low.
2. The film-forming additive of acrylic emulsion has very good water resistance, so as to keep the good appearance of the external wall, otherwise it is easy to whiten. Li Di Coatings understands that some companies' granite coatings will turn white after heavy rain.
3, because it will change back to its original state after this sun exposure. This is due to the poor water resistance of the outer layer.
4. In some places, in order to increase the fixity of exterior wall emulsion, a large number of surfactants are used and sodium benzoate is poured in, which will cause poor water resistance of coatings.
Friends have got a general idea of what principle material our granite coating is made of, so we already know the function and benefits of this kind of granite coating, and we can use it safely in the future, and we also know the precautions of granite coating, so friends will pay more attention to us in the future.
