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 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 of this product at room temperature?
The product cures at room temperature within 18–72 hours. The higher the temperature and humidity, the shorter the curing time. Under normal temperature conditions, it is completely cured in approximately 18 hours.
What are the base surface requirements before construction?
The concrete base surface must be cleaned, repaired flat, and polished to a suitable roughness. The concrete strength should reach C25 or above, and the moisture content must be less than 8% before application.
How should this product be mixed before use?
Add 0.7%–1% water to QT and stir thoroughly before use. It is recommended to use the entire mixture within 40 minutes after mixing to prevent a sharp increase in viscosity that would affect application.
What is the recommended application thickness?
The recommended scraping thickness is 1–1.5㎜ per layer. The dosage is ≥1.3–1.5 kg/mm per square meter. Multiple layers can be applied with a scraping interval of approximately 12 hours between each layer.
What are the storage requirements for this product?
The product should be stored sealed in a dry, cool, and well-ventilated environment, away from direct sunlight, rain, and any sources of ignition or fire.
What fields and venues is this product suitable for?
This product is widely used in schools, stadiums, and other multi-purpose venues. It is ideal for sport court surfaces and similar applications requiring durable, flexible, and weather-resistant coatings.
