Construction Description:
Before use, mix component A fully and evenly, pay special attention that have to stir thoroughly to the bottom of the barrel until there is no sediment on the bottom. Weight accurately as the required weight according to A: B = 1:6 (weight ratio) calibrated by the package, pour it into the batching container, mix it manually or mechanically for 2-5 minutes, and then can carry out the construction after fully mixing.
The mixed materials should be used up within 20 minutes.
Under standard conditions, the product can be used within 2-24 hours after the primer surface is dry.
Scraping construction can be adopted.
Coating amount: 1mm / m2 theoretical amount is 1.2kg.

Substrate treatment:
The surface floating ash and loose concrete slurry shall be removed from the concrete base material first, and the alkaline substance on the concrete surface shall be removed.
The concrete surface shall be dehydrated and dried.
The concrete surface shall be repaired and leveling.
If construction on the old paint film, the old paint surface should be rough making treated.
This material needs to be coated with a special primer for elastic materials.
Construction conditions:
The coating temperature is 5-35 ºC, the relative humidity is less than 80%, and the surface temperature of the substrate is more than 3 ºC higher than the dew point.
Outdoor painting is not allowed in rainy, snowy, foggy or strongly windy days.
Good ventilation shall be ensured at the construction site, and fire source and heat source shall be isolated at the same time.
Storage:
The product shall be stored in a cool, dry and ventilated indoor warehouse, with a storage temperature of 5 ºC - 30 ºC, Keep away from heat and fire sources, and the packaging containers shall be sealed. The shelf life is 12 months from the production date.
Safety:
It is strictly prohibited to have any fire source at the batching and construction site, and keep good ventilation. Construction personnel must wear protective equipment to avoid skin contact. If the paint splashes on the skin, it shall be cleaned immediately with a suitable detergent or soapy water. If it splashes into the eyes, it shall be cleaned repeatedly with clear water immediately to keep the eyes open and seek medical treatment immediately.
Structure of polyurea floor system:
System characteristics
Environmental protection.
Good elasticity, high elongation, comfortable foot feeling and release pressure.
Easy to clean and scrub resistant.
Impact resistance, scratch resistance, wear resistance.
Excellent fire performance.
Good sound absorption and shock absorption effect.
Good weather resistance.
Application recommendation
Airports, museums, libraries, schools, kindergartens, restaurants, casinos, hospitals, nursing homes, fitness clubs and other public facilities spaces
Solventless polyurea self-leveling technology:
Using polyurea elastomer technology, enhanced flexibility improves walking comfort, can alleviate sports fatigue; unique damping, with sound absorption and noise reduction. At the same time, the high elongation reduces the risk of secondary cracking of the base concrete, and resists scratches through deformation and repair.
