Packing

10kgs/drum or 20kgs/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 ℃, 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 (FAQ)

What are the primary applications of YP686?

YP686 is specifically designed for roof waterproofing, villa platforms, terraces, and various other waterproofing protection projects.

What is the suggested usage quantity and standard thickness?

The suggested consumption rate is 1.2 kg/mm/m². For the standard waterproof thickness of 1.5 mm, the calculated usage is 1.8 kg per square meter.

What are the required environmental conditions during construction?

Construction site temperature must be above 5℃, relative humidity below 85%, and proper ventilation should be maintained at all times.

How long does it take for the coating to dry and cure?

The surface dry time is under 4 hours, and actual dry time is under 24 hours. Room temperature curing takes 12 hours between steps, and full optimal film curing requires at least 7 days.

What base surface preparation is needed before application?

The concrete substrate must be clean, flat, polished for roughness, fully cured with a strength grade of C25 or above, and maintain a moisture content below 8%.

How should YP686 be stored?

It should be kept sealed in original 10kg/drum or 20kg/drum packaging in dry, cool, and well-ventilated areas, away from direct sunlight, rain, and ignition sources.
