In today's construction industry, the choice of exterior wall decoration materials is not only about aesthetics, but also about cost-effectiveness, durability and environmental adaptability. As a new type of exterior wall decoration material, real stone paint has been widely used in many projects due to its advantages of realistic imitation stone effect, strong texture, convenient construction and relatively low cost. However, for developers and builders, accurately calculating the comprehensive unit price of real stone paint is the key to controlling costs and improving competitiveness.
First of all, labor cost is an important part of the comprehensive unit price of real stone paint. In the current market, the labor cost of real stone paint spraying is roughly 22 yuan square meters. This cost includes factors such as the worker's operating skills, labor intensity, and construction efficiency. Due to the high technical requirements for the spraying of real stone paint, this part of the cost is relatively fixed, and there is a gradual trend.
Next, the material cost occupies the majority of the comprehensive unit price of real stone paint. Specifically, putty is used as a base treatment material, and its cost is about 216 yuan square meters, which directly affects the adhesion and final effect of the coating. Masking paper is used to protect the dividing line or the edge of the moulding at a cost of about 077 yuan square meters, although the proportion is not high, but it is an indispensable part of the details. The alkali-resistant sealing primer is to prevent the alkaline substances of the wall from reacting with the real stone paint and affecting the stability of the coating, and its cost is about 124 yuan square meter. And the cost of real stone paint itself is 1622 yuan square meters, which is the most critical part of the entire material cost, which is directly related to the final visual effect and weather resistance. Finally, the role of the covering agent is to enhance the stain resistance and weather resistance of the coating, and the cost is about 108 yuan square meter.
In addition, the cost of machinery is also a part that cannot be ignored. Take the construction hanging basket as an example, its cost is about 3 yuan square meters. Although this part of the cost is not high, it is a necessary expenditure for high-rise buildings to ensure construction safety and efficiency.
The management fee and profit are usually included in the comprehensive unit price according to a certain proportion, here we assume that it is 10 yuan per square meter. This part of the fee covers the cost of project management, quality control, risk prevention, etc., as well as the normal profit of the business.
Finally, the tax is a fee that must be paid according to the relevant national regulations, usually 5 yuan per square meter. This part of the cost is the embodiment of the national tax policy, but also part of the corporate social responsibility.
To sum up, the comprehensive unit price of exterior wall real stone paint can be roughly estimated as: labor cost of 22 yuan square meters, material cost of about 2147 yuan square meter, machinery fee 3 yuan square meter, management fee profit 10 yuan square meter, tax 5 yuan square meter. In total, the comprehensive unit price of real stone paint for exterior walls is about 6147 yuan square meter. This is only a rough estimate, and the actual project also needs to consider market fluctuations, construction difficulty, design requirements and other factors, so in actual operation, the construction unit needs to carry out detailed cost accounting according to the specific situation to ensure the economic and social benefits of the project. construction site
