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 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%.
- 3 Ventilation Conditions: Ventilation should be maintained during construction.
Operation Methods and Requirements
- 1 Mixing Ratio A:B = 1:1 (mass ratio) — Solvent is not allowed to be added. Before use, pour component B into a mixing bucket and add the same mass of component A by electronic weighing in proportion. Stir thoroughly for 2–3 minutes to prevent uneven mixing at the bottom of the bucket resulting in local non-solidification of the floor. Ready to use and prepare; the prepared polyurea coating should be used up within 15 minutes.
- 2 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 (note: 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 mixed evenly in proportion.
- 3 Pour the 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.
- 4 After curing, if encountering adverse weather such as rain, a layer of interface agent must be applied before proceeding to the next process.
- 5 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)
Q What is the mixing ratio for YP683/YP685 cold polyurea coating?
The mixing ratio is A:B = 1:1 by mass. Component B should be poured into the mixing bucket first, then component A is added by electronic weighing. Stir thoroughly for 2–3 minutes. No solvent should be added, and the prepared mixture must be used within 15 minutes.
Q How long does the YP683/YP685 polyurea coating take to dry?
The surface becomes dry in less than 4 hours, and the coating is fully dry within 24 hours under normal room temperature conditions. For optimal film performance, allow at least 7 days of curing after the final coat is applied.
Q Is the cold polyurea coating environmentally friendly and safe to use?
Yes. The YP683/YP685 cold polyurea coating is 100% solid content, free from solvents, heavy metals, and volatile organic compounds (VOCs), making it an environmentally friendly and safe choice for both indoor and outdoor applications.
Q What are the base surface requirements before applying the coating?
The concrete base surface must be cleaned, repaired, and polished to an appropriate roughness. The concrete should be fully cured with a strength of C25 or above, and the moisture content must be less than 8%. The next process should begin as soon as possible after surface preparation.
Q What are the typical applications for this cold polyurea coating?
This product is widely used for waterproofing roofs, swimming pools, and water parks; anti-corrosion flooring in production workshops and warehouses; silent and dust-free floors in schools, hospitals, and kindergartens; and sports venue surfaces such as basketball courts.
Q How should the cold polyurea coating be stored?
Store the coating in sealed containers in a dry, cool, and well-ventilated environment. Avoid direct sunlight and rain exposure. Keep the product away from any sources of fire or ignition at all times.
