Storage and Handling

Application method

● Clean the surface
● The paint should be fully stirred before use, if there are impurities, please filter it after the bubbles disappear. The product needs to be covered timely after use to prevent deterioration.
● Brush, roller, spray, dip are available, recommend to spray. (Spray gun model: W-71, pressure of the air pump: 1.5-3.5bar), can use 10% water to adjust the viscosity.
● Coating thickness is at least 90μm to ensure remove easily. Too thin easy to tear off, too thick easy to sagging.
● At 20℃/60% humidity /90μm conditions, surface dry time is about 30 minutes, real dry time is about 4 hours. At 60℃, the time is 15 minutes.
