DIRECTIONS Before using stir or using dynamic mixer mixing two components completely,Just mix a good raw material and mixing of raw materials before can not be together. Rate of cure will vary depending on temperature and other factors such as ventilation, film thickness, humidity, thinner. The temperature of stir will >15℃, otherwise thinner should be added for needed viscosity after stir.
Overmuch thinner will lead sag and slow cure rate, thin film, thinner should be added after mixed. Practical spreading rates may be reduced 5%—25% for wastage of different application conditions.

APPLICATION  

STEEL: The surface coated by primer or intermediate paint should be dry and clean, no oil and other pollutants. When overcoat on a two-component film such as epoxy paint, wharf's pavement quality for old film should be taken if more than the
longest accordance with time.
Don’t apply at temperatures below 5℃ or above 40℃. Don’t apply at relative humidity above 85% or when the surface is less than 3℃ above the dew point.
Don’t apply if there is fog, rain, snow or strong wind.
BRUSH/ROLLER: Suitable for small areas only. Apply even coats of the mixed material to the prepared surface. Thin if necessary with up to 0-15% with Epoxy Thinner X-5. Additional coats may be required to attain specified thickness.
CONVENTIONAL SPRAY: Thinning is not normally required, however 0-15% of Epoxy Thinner X-5 can be added.
AIRLESS SPRAY: Thinning is not normally required, however 0-5% of Epoxy Thinner X-5 can be added. Pump ratio is 23:1 or 32:1 and fluid tip is 0.33-0.38 mm.
Overcoating: Aged coating should be tested for lifting by a method such as ‘X’cut or crosshatch methods. If it lifts, remove it. The surface must be free of oil, grease and other contaminants.
Previous coat: Epoxy Coating
CLEAN UP: with Epoxy Thinner X-5
