PRODUCT SPECIFICATION
Junckers 14 mm 2-strip solid hardwood floors are factory finished and ready to install in accordance to Junckers Laying Instructions.
Each floor board is assembled from two rows of staves by a glued dovetail construction.
Each floor board is tongued and grooved on all four sides.
PRODUCT DATA / TOLERANCES
Nominal Board Dimensions
Thickness: 13.8 mm (±0.2 mm)
Width: 129.0 mm (±0.2 mm)
Length: 1830/900 mm (±1.0 mm)
Stave Lengths
623.5 mm and 467.5 mm.
Drying Method
Beech, all variants: Press dried.
Oak, all variants: Kiln dried.
Average Moisture Content, MC
Beech and Oak, all variants except Black Oak: 8 % (±2 %).
Black Oak: 9 % (±2 %).
NH3 treatment of Black Oak and Beech Sylvaket/Sylvared means that MC can´t be measured by using a conventional moisture meter but must be measured by the “dry weight method”.
Precision Engineering
Landing Deviation: 0.2 mm
(0.3 mm in localised areas).
Board ends are right angled at ±0.3 mm.

FACTORY SURFACE TREATMENT
LACQUERED
Beech & Oak:
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.
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.
Other colours:
Priming: Coloured stain.
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: Corresponding to a full surface saturation.
UNTREATED
Final sanding to grit 150.
