Storage
🌡️
Sealed storage of coatings in dry, cool, and well-ventilated conditions, avoiding sunlight and rain, and keeping away from sources of fire.
Construction Conditions
- 1 Base surface requirements: The concrete base surface should be cleaned, repaired flat, and polished to a certain roughness. Ensure that the concrete curing is completed, the strength reaches C25 or above, and the moisture content is less than 8%. After processing the base surface, the next process should be carried out as soon as possible.
- 2 Environmental temperature and humidity requirements: The environmental temperature at the construction site should be above 5℃, and construction can only be carried out when the relative humidity is less than 85%.
- 3 Ventilation conditions: Ventilation should be maintained during construction.
Operation Methods and Requirements
Add 0.7%–1% water to QT and stir well. During construction, in order to ensure the adhesion between layers, sanding is performed (Note: sanding floating dust must be cleaned with a vacuum cleaner). Roller coating sealing primer — after the primer is completely cured, thin scraping with a leather rake, the thickness of 1~1.5㎜ is appropriate. The scraping time interval before curing (generally about 12 hours, depending on the weather conditions on the site) until the required thickness.
⚠️ It is recommended to use all within 40 minutes after mixing, otherwise the viscosity will increase sharply, affecting continued use. After curing, proceed to the next process. It is completely cured in 18 hours at normal temperature. If there is bad weather such as rain after painting, an interface agent must be applied before the next process.

Frequently Asked Questions
Q
What is the curing time for this polyurethane coating?
The curing time is typically 18–72 hours. The higher the temperature and humidity, the shorter the curing time. Under normal temperature conditions, full curing is achieved within approximately 18 hours.
Q
What substrates is this product compatible with?
This product offers excellent adhesion to a wide variety of substrates. It is especially suitable for concrete base surfaces in sports courts, schools, stadiums, and other public facilities.
Q
How should the product be mixed before application?
Add 0.7%–1% water to QT and stir thoroughly. It is recommended to use the entire mixed batch within 40 minutes, as the viscosity will increase significantly after this time and may affect usability.
Q
What are the environmental requirements during construction?
Construction should only be carried out when the ambient temperature is above 5℃ and relative humidity is below 85%. Good ventilation must be maintained throughout the application process.
Q
How should this product be stored?
Store in sealed containers in a dry, cool, and well-ventilated environment. Keep away from direct sunlight, rain, and any sources of fire or ignition to ensure product quality and safety.
Q
What is the recommended application thickness and dosage?
The recommended scraping thickness is 1–1.5㎜ per layer. The suggested dosage is ≥1.3–1.5 kg per square meter per millimeter of thickness. The product is packaged in 30 kg drums for convenient handling on site.
