1、 What is real stone paint?
Composition: mainly made of natural colored sand, emulsion and related auxiliaries, hardened and hardened after curing, and looks like natural stone.
Features: strong decoration, wide application, water-based environmental protection, good pollution resistance, long service life, economic benefits, no potential safety hazards. With good adhesion and freeze-thaw resistance, it is especially suitable for use in cold areas. At present, water sand has the trend of replacing real stone paint!
2、 Classification and price of real stone paint (greatly different according to terrain difference)
Single color: 35 + 35 = 70 yuan / M? (material + Construction)
Tricolor: 50 + 40 = 90 yuan / M?
Schist: 70 + 40 = 110 yuan / M?
Elasticity: above 150 yuan / M. It belongs to high-grade real stone paint, which can effectively cover the subtle cracks in the wall.
3、 According to the cost and quality, the grade of real stone paint can be divided into low, medium and high grade suggestions: in the same project, different grades of products are selected according to different property types and different parts in the same single building.
4、 Construction process of real stone paint
Putty primer main paint finish
5、 Five steps of material quality identification: 1. Investigation: watermelon is sweet or not to see where it grows, the same with real stone paint, the production workshop must see.
2, see: roughly determine whether the emulsion content is appropriate. Open the packing barrel to see if it is moist enough or dry.
3, touch: you can roughly judge the quality of the emulsion. Grab a handful of paint and put it in your hands for a moment. After drying the air, wash your hands. After the emulsion is dried, a protective film will be formed. It will tear off a piece of dead skin and tear it off with one hand.
4. Bubble: it can judge the quality of aggregate. Take a jin of paint and put it in a large bottle of mineral water bottle, shake it repeatedly, soak it for more than 2 hours, and then stand still to observe whether the upper water is discolored and turbid. If the color changes, it means that the color paste is added. If the color is turbid, it may be sandy with poor hardness or stone powder.
5. Pick: the material quality can be judged according to the coating quality. After three days of construction in good weather, the coating can not be removed with fingernails. If it can be drawn, it indicates that the coating is too soft, the main reason is that the emulsion is not suitable or the content is low.
6、 Summary
Comprehensive unit price = material price + construction price.
Construction price: single color, multi-color, rock slice is generally within 40 yuan / M.
Material price: mainly including putty, primer, main paint and finish paint. Generally, 12 yuan / M? (putty 5 + primer 2 + finish 5) is basically fixed, and the price of main paint changes. The price of the lacquer is due to the difference of the material choice. The price difference is relatively large, which is related to the grade selection and the main paint consumption. The core factor is the choice of aggregate in the main paint, the grade and dosage of the emulsion.
The price of main paint is generally calculated according to the amount of main paint per square meter (theoretical coating rate kg / M?) (taking medium grade pure C as an example):
Single color: 8-12 yuan / kg?
Rock slice: 12-18 yuan / kg?
Elasticity: 15-25 yuan / kg?
Main factors affecting quality:
① Design details: the use of real stone paint to imitate stone, we must pay attention to the treatment of details in the design.
② Material quality: affects durability.
③ Construction quality: three materials and seven technologies.
Based on the analysis of the quality problems of real stone paint in the industry, the statistical data according to the causes are as follows:
20% raw material problem;
35% of the technical schemes are not perfect;
45% of the construction is not standardized and the workers' technology is not stable.
