Aluminium treatment and priming carried out at the factory in a continuous process with continuous quality control is advantageous to the overlacquering of the stove-lacquered ALUCORE^® surface.

ALUCORE^® overlacquering procedure:

• Pre-cleaning of the panels using methylated spirit
• Grinding the surfaces with wet abrasive paper (grain size 360)
• Removing grinding dust with a lintfree cloth moistened with spirit
• For the top coat, please follow the instructions of the top coat supplier

Please note:

• The maximum permissible temperature of the material (ALUCORE^® panels) must not exceed 70°C when applying fast-drying methods. During the drying process at high temperatures the ALUCORE^® panels must be positioned or stored with great care to prevent deforming.
• ALUCORE^® cut edges should not be in contact with organic solvents for a prolonged period of time to avoid weakening the bond.
• ALUCORE^® panels lacquered or overlacquered at a later stage should not be bent or folded. The lacquer in the bends or folds may be damaged due to the low elasticity of the top coat.
• Please make a test prior to overlacquering and follow the instructions of the lacquer suppliers.

The composition of lacquer coating for ALUCORE^® is basically the same as those for mill-finished aluminium surfaces. It is advisable to be familiar with coating systems and materials as well as working methods for aluminium.
