Overcoating

Consult Hempel’s specification for more information.

DRYING CONDITIONS

To obtain the drying time stated, it is important to maintain sufficient ventilation during application, drying and curing.

OVERCOATING DETAILS

If the maximum overcoating interval is exceeded, roughening of the surface is necessary to ensure intercoat adhesion.
The surface must be clean before overcoating.

OTHER REMARKS

Epoxy coats have an inherent tendency of chalking in outdoor exposure. This does not affect the performance of the coating.
Hempel’s Specification supersedes any recommendations given in the Product Data Sheets.
