Application steps

APPLICATION

Stir product mechanically until a uniform liquid has been achieved. Use low speed electrical stirrer (300-400rpm) tp avoid air entrapment.

For roller application use short piled roller. For airless application use tip size 0.38 to 0.53mm/ Angle 40° to 60°.

CLEANING OF EQUIPMENT

Clean all tools and application equipment woth water immediately after use. Hardened and/ or cured material can only be removed mechanically or with proprietary paint stripper.
