FACTORY SURFACE TREATMENT
Lacquered
Beech, Oak & Ash:
Priming: Several coats of UV-light curing primer.
Top finish: Two-component polyurethane lacquer, silk- or ultra matt.
Total film thickness: Min. 40 µ.
Beech SylvaKet and SylvaRed:
Pre-treatment: Coloured throughout with a NH3-treatment to achieve a light brown colour.
Before lacquering Beech SylvaRed is also toned with a reddish stain. If Beech SylvaRed is sanded to bare wood, it will appear like Beech SylvaKet.
Priming: Several coats of UV-light curing primer.
Top finish: Two-component polyurethane lacquer, silk- or ultra matt.
Total film thickness: Min. 40 µ.
Ash Nordic, Beech Nordic & Oak Nordic:
Priming: White toned stain.
Intermediate treatment: Several coats of UV-light curing lacquer.
Top finish: Two-component polyurethane lacquer, ultra matt.
Total film thickness: Min. 40 µ.
Oak Pearl:
Priming: Water based transparent stain.
Intermediate treatment: Several coats of UV-light curing lacquer.
Top finish: Two-component polyurethane lacquer, ultra matt.
Total film thickness: Min. 40 µ.
Black Oak:
Pre-treatment: Coloured throughout with a NH3-treatment to achieve a dark brown colour.
Intermediate treatment: Several coats of UV-light curing lacquer.
Top finish: Two-component polyurethane lacquer, ultra matt.
Total film thickness: Min. 40 µ.
Oiled
Priming: Surface saturation using oxidative drying urethane oil.
Top finish: Oxidative drying urethane oil.
Total oil consumption: Addition to a full surface saturation.
Untreated
Final sanding to grit 150.
