Applications (Non-exposed type)
Engineered for excellence, spray polyurea is meticulously crafted for use on external walls, swimming pools, roofs, sports stands, as well as in industrial anti-corrosion scenarios, tunnel linings, and parking facilities. This versatile protective solution shines with its exceptional durability, superior waterproofing capabilities, and unmatched corrosion resistance, making it an indispensable choice for lasting protection.
Packing
A: 220kg B: 210kg
Storage
For optimal longevity, store this product in a cool, dry, and well-ventilated indoor environment, ensuring a storage period of up to one year.
Construction Conditions
1. Base surface requirements: Ensure the concrete base surface is meticulously cleaned, repaired to a flawless flatness, and polished to the requisite roughness. Confirm the concrete curing process is complete, with a strength rating of C25 or higher and moisture content below 8%. Promptly proceed with further processes post preparation to maintain integrity.
2. Environmental temperature and humidity requirements: The construction environment must be maintained at temperatures between 5~35 ºC, with the base surface temperature being at least 5 ºC above the air dew point. Optimal humidity levels should be within 30% to 80% to guarantee quality application.
3. Ventilation conditions: Consistent ventilation is crucial during the application process, though construction should be paused in the event of strong winds.
Operation Methods and Requirements
Thoroughly mix component B of the coating prior to use to ensure uniform consistency and optimal application performance.
A: B=1:1 (volume ratio)
Professional construction teams are required to employ specialized spraying equipment for application, ensuring the material temperature is maintained between 50~80 ºC for ideal results.
Generally, you can proceed with the subsequent process 12 hours post-application. If the interval between processes exceeds 24 hours, it's critical to apply an interface agent prior to continued construction. In the instance of adverse weather conditions, such as rain post-application, an interface agent must be applied before resuming to the next process to ensure seamless integration.
Typically, the paint film should undergo a curing period of no less than 7 days post-application to achieve its full performance potential, ensuring a resilient and durable finish.
Suggested Use Quantity
1.2kg/mm/m2,
To achieve the waterproof national standard thickness of 1.5mm, use 1.8kg per square meter.
For anti-corrosion national standard thickness of 2.0mm, apply 2.4kg per square meter.
