Surface Preparation: cover the surface should be dried, sanded, grinding dust must be thoroughly removed.
Coating application: Before application the lacquer mix if necessary filtered through a nylon mesh. To adjust the viscosity of the diluent used RML solvent grades 646 or 647.
The varnish applied paint sprayer, bulk, swab or brush thin, uniform layer without sagging at ambient temperature, the paint material and the surface is not lower than 15 ° C, relative humidity (65 ± 5)% . Wood moisture content should not exceed 10% .
When applied in several layers of lacquer (three - four layers) after each drying lacquer layer is given 1 hour at a temperature (20 ± 2) ° C. The last layer is dried 24 h. The recommended polishing film type polishing composition 291 to improve gloss.
varnish consumption for layer coating is 85 - 105 g / m2.
Precautions : painting work carried out in a ventilated area, to protect your hands to use rubber gloves.
