It is allowed to increase the viscosity of the varnish during storage, if, when diluted with a solvent to a conditional viscosity, the varnish will correspond to the TNPA in all respects.

Coating:  before use, the lacquer is thoroughly mixed and, if necessary, diluted with xylene, solvent or a mixture of one of these solvents with white spirit (nephras – C4-155 / 200) in the following weight ratios: white spirit (nephras – C4-155 (200) – xylene = 3: 2; white spirit (nefras – C4-155 / 200) – solvent = 1: 1.

Lacquer applied to the surface by spraying, brushing or dipping

Precautionary measures:  When carrying out the termination of the room. Rubber gloves to protect your hands.
