The substrate should be smooth, solid, clean, dry without Sharp concave and convex points, honeycomb, pocking marks, peeling, free of bulges, greasy before application. It is better coating 3 times with scraper. When the first coat isn't sticky, the second coat can be applied, the first layer is recommended being applied in thinner layer for better releasing gas generated during reaction. The second coat should be applied in different direction to the first coat. The optimal coating rate is 2.0kg/m² For thickness of 1.5mm.


* Can be made into many kinds of colour.

* Contains no asphalt, tar or any solvents, no harm to constructer.

* Easy for applying.

* Free from pollution to the environment, No toxity after curing, No corrosion to base material, High solid content.

* One component, convenient for construction, No need of mixing.


* Jot99 should be inverted in dry and shady indoor, avoid sunlight and moisture.

* It is normally that a film formed on the surface of coating. It can be used normally when removing the film.

* The rest coating should be sealed in order to avoid moisture.

* Pay attention to protect the waterproofing membrane during constructing period and after finished.

* Warehouses and construction of the site is strictly prohibited fireworks.
