Packing
📦 10 kgs/drum or 20 kgs/drum
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
- 🧱 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.
- 🌡️ Environmental temperature and humidity requirements: The environmental temperature at the construction site should be above 5°C, and construction can only be carried out when the relative humidity is less than 85%.
- 💨 Ventilation conditions: Ventilation should be maintained during construction.
Operation Methods and Requirements
YP686 can be opened for direct construction.
During construction, in order to ensure interlayer adhesion, polishing treatment should be carried out (note: polishing floating dust must be cleaned with a vacuum cleaner). Roll coat solvent-free epoxy sealing primer. After the primer is completely cured, pour YP686 polyurea onto the floor and scrape it evenly with a trowel (3mm or 5mm trowel can be selected according to thickness requirements). After curing, proceed to the next process. Curing at room temperature for 12 hours; if encountering adverse weather such as rain after coating, a layer of interface agent must be applied before proceeding to the next process.
⚠️ Note: Under normal circumstances, the paint film should be cured for at least 7 days after completion of painting to ensure optimal performance of the paint film.

Frequently Asked Questions
What is YP686 one-component polyurea and how does it cure?
YP686 is a one-component brushable polyurea waterproof coating that cures at room temperature without requiring any special equipment or mixing of two components. It achieves surface dryness in under 4 hours and full cure within 24 hours under normal conditions.
What substrates can YP686 polyurea adhere to?
YP686 offers excellent adhesion to a wide variety of substrates including concrete, cement mortar, metal, and other common construction surfaces, making it highly versatile for waterproofing applications.
What are the main application areas for YP686?
YP686 is primarily used for roof waterproofing, villa platforms, terraces, and other surfaces requiring reliable waterproofing protection. It is suitable for both residential and commercial construction projects.
How much YP686 polyurea is needed per square meter?
The recommended usage rate is 1.2 kg per mm per m². For the national standard waterproof thickness of 1.5 mm, approximately 1.8 kg of YP686 is required per square meter.
What are the storage requirements for YP686?
YP686 should be stored in a sealed container in a dry, cool, and well-ventilated environment. It must be kept away from direct sunlight, rain, and any sources of ignition to maintain product quality and safety.
What environmental conditions are required during construction of YP686?
Construction should be carried out when the ambient temperature is above 5°C and relative humidity is below 85%. Adequate ventilation must be maintained throughout the application process. The concrete base must have a moisture content of less than 8% and a strength of C25 or above.
