Before application if necessary to dilute a varnish solventy, a xylol or mix of one of them with white spirit in ratios: white spirit — a xylol 3:2, white spirit — a solvent 1:1. Time of drying of a varnish at a temperature (20±2) — no more than 72 hours, at 90 °C — no more than 3 hours. A varnish expense on a single-layer covering — (70-75) g/m2.
