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
Environmental 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
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.
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 (FAQ)
Q1
What is YP686 one-component polyurea coating and what makes it different from two-component polyurea?
YP686 is a single-component, moisture-curing polyurea waterproof coating with 93% solid content. Unlike two-component systems, it requires no mixing equipment and can be applied directly from the drum, significantly simplifying the construction process while maintaining excellent physical and chemical performance.
Q2
What surfaces is YP686 polyurea coating suitable for?
YP686 is suitable for concrete base surfaces with a strength of C25 or above and moisture content below 8%. It is widely used for roof waterproofing, villa platforms, terraces, and other areas requiring reliable waterproof protection. It adheres well to a variety of substrates.
Q3
How long does YP686 take to cure, and when can the next construction step begin?
YP686 has a surface dry time of less than 4 hours and a full dry time of less than 24 hours at room temperature. For optimal interlayer adhesion, curing for 12 hours at room temperature is recommended before proceeding to the next step. The complete paint film should cure for at least 7 days to achieve peak performance.
Q4
What are the recommended environmental conditions for applying YP686?
Construction should be carried out when the ambient temperature is above 5℃ and relative humidity is below 85%. Adequate ventilation must be maintained throughout the application process. Avoid applying the coating in rainy or excessively humid conditions.
Q5
How much YP686 polyurea is needed per square meter, and how is it applied?
The standard usage rate is 1.2 kg per mm per m². For the waterproof national standard thickness of 1.5mm, approximately 1.8 kg per square meter is required. YP686 can be applied using manual scraping with a trowel (3mm or 5mm) or roller coating, making it efficient and easy to control on-site.
Q6
How should YP686 polyurea coating be stored to maintain its quality?
YP686 should be stored in sealed drums in a dry, cool, and well-ventilated environment, away from direct sunlight, rain, and any sources of ignition or fire. Proper sealed storage ensures the product maintains its performance throughout its shelf life.
