In recent years, polyurea spraying technology has been widely used in construction, industry, transportation, and other fields with its super waterproof, anti-corrosion, and impact resistance performance. However, the problem most users are concerned about the procurement problem is always how much per square meter?" This article combined market research data, from the price range, influencing factors, and purchase strategies to help users reasonably plan budget and avoid pitfalls.

According to industry statistics, the current domestic polyurea spraying project quotation is generally between 50-150 yuan / square meter, and the specific price varies greatly due to the material type, construction technology, project scale, and other factors:

-Pure Polyurea Spraying: Optimal performance, high unit price, about 20 USD / ㎡;

-Hybrid Polyurea Spraying: cost-effective choice, about 13 USD / ㎡;

-Special Functional Polyurea(high-temperature resistance,  antistatic resistance): Price is increased by 20% -30%.

In addition, the larger the construction area, the lower the unit price is usually. For example, large projects with 1 than 1000 ㎡ may enjoy a discount of 5% -10%, while small area repair projects (such as partial roof waterproofing) may exceed 20 USD / ㎡ due to the high allocation of construction costs.

Polyurea raw materials (such as isocyanate, and amino polyether) account for 40% -60% of the total project cost. In 2025, affected by the fluctuation of international raw material prices, the raw material price increased by about 8% year on year, directly driving the fluctuation of spraying quotation.

The spraying thickness of conventional waterproof engineering is 1.5-2.0mm. If it increases to more than 3.0mm, the material dosage will double and the price will rise simultaneously. In addition, the construction of special-shaped structures (such as pipelines and equipment base) is difficult, and the labor cost increases by 10% -15%.

If there are cracks, sand lifting, and other problems at the base level, additional grinding and filling pretreatment are required, and the cost is about 1-2 USD/ ㎡. Some enterprises provide "testing + construction + quality assurance" integrated service, although the price is high but can reduce the risk of later maintenance.

The labor cost in first-tier cities is higher , and the unit price of spraying is generally 10-20 yuan / ㎡ higher than that in second-and third-tier cities; while in industrial-intensive areas (such as Yangtze River Delta and Pearl River Delta), the price competition is more intense due to the concentration of suppliers.

The polyurea materials provided by the regular manufacturers cooperate with the professional construction team, the price may be 20% -30% higher than the small workshop, but can ensure the environmental protection of the material and more than 10 years of warranty.

-Ordinary building waterproof (such as basement, roof): choose half polyurea (7-11 USD / ㎡) to meet the demand;

-High corrosion environment (such as chemical plant, Marine platform): pure polyurea (above 13 USD / ㎡) must be used.

Some low-cost packages may cut corners (such as reducing the spraying thickness and the use of inferior thinner), resulting in shortening the life of the waterproof layer. It is recommended for the supplier to provide the material test report and specify the construction acceptance criteria.

The professional team can adjust the formula and process according to the site environment to avoid disputes of rights and responsibilities caused by the separation of materials and construction. For example, the "0 leakage" polyurea product launched by Santam Technology enterprise has been successfully applied in key projects such as high-speed railway tunnels.

Before the rainy season (March-May) is the construction season, the price is high; winter (11-January) demand decreases, some enterprises will launch discount activities, can save up to 15% budget.

With the breakthrough of domestic production technology of polyurea raw materials, the material cost is expected to be reduced by 5% -8% in 2026. At the same time, the popularity of automatic spraying equipment has reduced the manual dependence, the construction efficiency is increased by more than 30%, in the long run or will drive the market price stability.

 

There is no fixed answer to how much per square meter, which should be combined with the comprehensive evaluation of specific project needs, supplier qualification, and service quality. It is suggested that users start from the long-term use cost and choose regular manufacturers and high-quality construction teams to ensure the durability and safety of the project.
