Construction Conditions
Painting methods and requirements
- Mix component B of the coating evenly before use
- A: B=1:1 (volume ratio)
- Professional construction teams must use professional spraying equipment for construction, and the material temperature during spraying should be controlled between 50~80 ℃.
- In general, the next process can be carried out after 12 hours of painting. If the construction interval exceeds 24 hours, a layer of interface agent needs to be applied before construction can proceed. If encountering adverse weather such as rain after coating, a layer of interface agent must be applied before proceeding to the next process.
- Under normal circumstances, the paint film should be cured for at least 7 days after completion of painting to ensure the best performance of the paint film.

Frequently Asked Questions (FAQ)
What are the primary applications of this polyurea product?
This product is suitable for external wall waterproofing, swimming pool waterproofing, other building waterproofing needs, and sports stand protection.
What are the requirements for the concrete base surface before application?
The concrete base surface must be cleaned, repaired flat, and polished to a certain roughness. Curing must be complete, with concrete strength reaching C25 or above, and the moisture content must be below 8%.
What is the recommended mix ratio and application temperature?
The volume ratio of Component A to Component B is 1:1. It should be applied using professional spraying equipment, maintaining a material spraying temperature between 50~80 ℃.
How much material is required per square meter?
For waterproofing (national standard thickness of 1.5mm), the suggested dosage is 1.8kg/m². For anti-corrosion (national standard thickness of 2.0mm), the suggested dosage is 2.4kg/m².
What are the recommended storage conditions for this product?
The product should be stored in a cool, dry, and ventilated indoor warehouse. Under these conditions, the storage shelf life is one year.
How long does the paint film require to fully cure?
The paint film should be cured for at least 7 days after the painting process is completed to achieve its optimal physical and chemical performance.
