Hardener is sensitive to moisture and hence needs to be stored in a dry place. Keep the can tightly closed after use. After exposure in a contaminated environment, clean the surface with high-pressure fresh water hosing and allow it to dry before applying an overload. If the maximum recoat interval is exceeded, roughen the surface to ensure intercoat adhesion.

As a general rule, inhalation of solvent vapour or paint mist and eye and skin contact with the liquid paint should be avoided. In addition, national and local safety regulations should be followed.
