Construction Conditions
- Base Surface: 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.
- Temperature & Humidity: 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%.
- Ventilation: Ventilation should be maintained during construction.
Operation Methods and Requirements
- Mixing Ratio A:B = 1:1 (mass ratio) — No solvent allowed. Pour component B into a mixing bucket and add the same mass of component A by electronic weighing. Stir thoroughly for 2–3 minutes to prevent uneven mixing at the bottom of the bucket, which could result in local non-solidification of the floor. The prepared polyurea coating should be used up within 15 minutes.
- During construction, first apply solvent-free epoxy anti-corrosion sealing primer. After the primer is completely cured, polish the area to ensure inter-layer adhesion. Polishing floating dust must be cleaned with a vacuum cleaner.
- After cleaning and polishing the floating dust, use solvent-free polyurea intermediate coating combination material, mix evenly in proportion, then pour this combination material onto the floor and scrape it evenly with a trowel (3mm or 5mm trowel can be selected according to thickness requirements).
- After 24 hours of curing, the next process can proceed. If the construction interval exceeds 48 hours, a layer of interface agent needs to be applied before construction can proceed.
- After curing, if encountering adverse weather such as rain, a layer of interface agent must be applied before proceeding to the next process.
- Under normal circumstances, the coating film should be cured for at least 7 days after completion of painting to ensure optimal performance of the paint film.

Frequently Asked Questions (FAQ)
What is the mixing ratio for YP683/YP685 two-component cold polyurea?
The mixing ratio is A:B = 1:1 by mass. No solvents are permitted. Use electronic weighing for accuracy and stir thoroughly for 2–3 minutes. The prepared mixture must be used within 15 minutes.
How long does YP683/YP685 polyurea take to cure?
Surface drying occurs within 4 hours, and full drying is achieved within 24 hours at room temperature. For optimal film performance, allow at least 7 days of curing after the final coat is applied.
Is this polyurea coating environmentally friendly?
Yes. YP683/YP685 is 100% solid content, completely free of solvents, heavy metals, and volatile organic compounds (VOCs), making it a safe and environmentally responsible coating solution.
What are the recommended application thickness and usage quantities?
The standard usage rate is 1.2 kg per mm per m². For waterproofing at 1.5mm thickness, approximately 1.8 kg/m² is required. For anti-corrosion applications at 2.0mm thickness, approximately 2.4 kg/m² is required.
What construction conditions are required for proper application?
The ambient temperature must be above 5℃ and relative humidity below 85%. The concrete substrate should have a strength of C25 or above and moisture content below 8%. Adequate ventilation must be maintained throughout the application process.
How should YP683/YP685 polyurea coating be stored?
Store in sealed containers in a dry, cool, and well-ventilated area. Keep away from direct sunlight, rain, and all sources of fire or ignition. Proper storage ensures product quality and extends shelf life.
