Application steps

APPLICATION

Stir product mechanically until a uniform liquid has been achieved.
Use a low speed electrical stirrer (300-400 rpm) to avoid air entrapment.
For roller application use short piled roller.

For airless application use tip sizes from 0.38 to 0.53 mm and angle from 40° to 60°.

CLEANING OF TOOLS

Clean all tools with water immediately after use. Hardened and/or cured material can only be removed mechanically.
