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 & 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 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
QWhat is YP686 one-component brushable polyurea used for?
YP686 is primarily used for roof waterproofing, villa platforms, terraces, and other surfaces requiring waterproofing protection. It forms a dense, seamless coating that effectively prevents water infiltration.
QDoes YP686 require special equipment to apply?
No special equipment is needed. YP686 can be applied using manual scraping with a trowel (3mm or 5mm) or roller coating, making it professional, convenient, and controllable for construction teams.
QHow long does YP686 take to fully cure?
The surface dry time is less than 4 hours, and the actual dry time is less than 24 hours. However, for optimal paint film performance, the coating should be fully cured for at least 7 days after application is completed.
QWhat are the required environmental conditions for applying YP686?
The construction site temperature should be above 5°C, and the relative humidity must be less than 85%. Adequate ventilation should also be maintained throughout the construction process.
QHow much YP686 is needed per square meter?
The recommended usage is 1.2 kg per mm per m². For the standard waterproof thickness of 1.5mm, approximately 1.8 kg per square meter is required.
QHow should YP686 be stored to maintain its quality?
YP686 should be stored in a sealed container in dry, cool, and well-ventilated conditions. It must be kept away from direct sunlight, rain exposure, and any sources of fire to ensure product stability and shelf life.
