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 the continued use. After curing can 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 painted before the next process.
Suggested Use Qty
Single square meter dosage ≥ 1.3–1.5 kg/mm
Frequently Asked Questions (FAQ)
What is the curing time for this product at normal temperature?
At normal temperature, the product is completely cured in approximately 18 hours. However, the full curing range is 18–72 hours depending on temperature and humidity conditions — higher temperature and humidity result in shorter curing time.
What substrates is this coating compatible with?
This product has excellent physical and chemical properties and provides good adhesion to a wide variety of substrates, including concrete surfaces used in schools, stadiums, and other common facilities.
How much product is needed per square meter?
The recommended single square meter dosage is ≥ 1.3–1.5 kg/mm. Please plan your quantity accordingly based on the total surface area to be coated.
What are the environmental requirements for application?
The construction site temperature should be above 5℃ and relative humidity below 85%. Adequate ventilation must be maintained throughout the application process. Avoid application in rainy or extremely humid conditions.
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.
What should I do if the mixed product is not fully used within the working time?
It is strongly recommended to use the entire mixed batch within 40 minutes after mixing. Beyond this window, the viscosity increases sharply, making the product difficult to apply and significantly affecting performance. Mix only the quantity needed for immediate use.
