Board structure

Sizes and finishing


15 mm WBP/MR birch faced ply + 6 mm hardwood wear layer (tolerance on total thickness +/- 0,2 mm)
12 mm WBP/MR birch faced ply + 4 mm hardwood wear layer (tolerance on total thickness +/- 0,2 mm)

Please note:
Top layer thickness is measured prior to the finishing process. Finishing processes will affect the overall thickness.


140 mm, 160 mm, 180 mm, 200 mm


60% – 1800-2700 mm
40% – 600-1500 mm


Lacquer, oil, unfinished. We have possibility to make brushed floors (if it is necessary – with adding of stain).

Installation recommendations
  1. Engineered flooring is intended for use as a finishing material for floors in living rooms and in public areas, with stable climatic conditions. Optimal conditions: temperature 18-22 ° C, humidity 40 – 65%. Engineered flooring can’t be laid in areas where humidity exceeds 70%, i.e. in bathrooms, saunas, etc .;
  2. Engineered flooring must be laid/mounted indoors, heated to room temperature in winter.
  3. Basis, on which Engineered flooring will be mounted should be flat, dry, solid, clean and smooth (roughness should not exceed 2 mm per 1 linear meter of the surface). On the thus-prepared foundation should be laid isolating film thickness of 0.2-0.4 mm PE foam and glued with waterproof tape (duct tape).
  4. To check whether the screed has dried, you should use PE foam pieces (50 x 50 cm). These pieces should be expanded in several places on the floor, and the edges tightly pasted with duct tape. You can start mounting of the flooring only if after 24 hours the film is not “steamed” and the coupler surface didn’t change its color.
  5. The floors in the original packaging, prior to assembly, should be subjected to acclimatize for at least 72 hours in the room in which will be installed (at min. 18-20 ° C and a relative humidity of 40 – 65%).
  6. The floors can be removed from the packaging after acclimatization right before installation. Mounting of the floor is recommended in temperature of 18 – 22 ° C and humidity of 65%;
  7. Each floorboard/plank must be checked (before and during installation) for possible damages, visible “naked eye” defects (differences in decor, size, degree of polishing, etc. – it is very important at this point to ensure good lighting).
  8. For adhesive mounting of “floating floor” recommend to use adhesives, based on PVA dispersions like next: KLEIBERIT D3 and D4 or its analogues (gluing the longitudinal and transverse groove with dispensing container (Bottles)).
  9. For mounting adhesive tightly to the coupler recommend the use adhesives which do not contain water. For example glue KLEIBERIT MS583.8 or its analogs. (This is the glue that will eventually not lose elasticity).
  10. Assembled/mounted floors create a so-called “floating floor”. So you cannot stick it, nail or otherwise attach to the bottom of the floor or the wall after installation.
  11. For the best visual effect floor boards recommended to lay along the main source of light (perpendicular to the window).
  12. Between the floorboards and all immovable elements (columns, sills, doors, pipes, walls, etc.) should be distance of 10 mm, the so-called “expansion joint gap.” For this, during assembly, must be used distance wedges because floorboard under the influence of temperature and humidity fluctuations expands and contracts.
  13. The planks at the entrance of the room, after installation, should be protected with special doormats or carpets that protect the floor from the negative effects of sand and moisture.
  14. On the legs of chairs, tables and other furniture should use felt pads, which must be periodically cleaned of sand and mud.
  15. General Notes: spilled water must be removed immediately. Furniture cannot “drag” on the surface of the floor. You should lift it, move and then put (to avoid scratches on the surface).
Application methods of flooring
“Deck” from the boards of variable length straightly or diagonaly.
“Herringbone” from the boards of constant length straightly or diagonaly.
