  Easy Fencing

Inspection: Prior to installation, inspect planks in daylight for visible faults/damage • check if subfloor/site conditions comply with the specifications described in these instructions • if you are not satisfied do not install, and contact your supplier.


Tools and materials required: Electric saw • spacers • pencil • set square • PE film • adhesive tape.


Before laying: Measure the room at right angle to the direction of the planks • planks in the final row should be at least 5 cm wide • for this purpose, planks in the first row can be cut to smaller size • shuffle planks in order to obtain a pleasant blend of shades • lay planks preferably following the direction of the main source of light • we recommend laying on wooden floors crossways to the existing floorboard • planks must not be nailed or screwed to the subfloor • skirting boards must not be fixed in a way which restricts the movement of the floor.


Expansion gaps: provide 10 mm (3/8”) expansion gaps to the walls and other fixed objects • areas greater than 100 m² (900 sq. ft) or 10 m (30 feet) in either direction, transitions between rooms and asymmetrical areas require extra expansion gaps.

Starting the first row

Start in the corner • turn the tongue side of the plank to the wall • maintain a gap of 10 mm (3/8”) on the short side.

Starting the first row Hold the next plank at an angle against the first one and lay it flat on the floor • complete first row in the same way. Cut final plank of the first row to correct length • start next row with the piece leftover (must be at least 300 mm (12’’) long) • ensure that end joints are staggered at least 300 mm.
Cork flooring second row Place first plank of the new row with the tongue side at an angle against the groove side of the plank in the previous row • press forward and lay it flat at the same time.
Cork flooring second row Place short end of the plank at an angle against the previous installed plank and fold down • ensure that the plank is positioned on the integral locking strip of the plank in the previous row.
Cork flooring second row Lift planks (together with the previous laid in the same row) lightly up (about 30 mm (9/8’’)), push it against the row in front and then put it down. Adjust the distance to the wall to 10mm (3/8’’) when three rows are completed • proceed installation as described above until reaching the opposite wall.
Transport, Storage, Acclimation:
  • Transport and store cartons in lay down, flat position
  • Sticker-stack planks at room temperature for at least 72 hours outside of their packaging prior to installation. Watch The Video
  • Room temperature must be at least (65F) before and during installation
Subfloor Requirements:


  • Floating floors can be laid on top of most hard surfaces (e.g. concrete, ceramics, wood)
  • Soft subfloors (e.g. carpets) must be removed
  • The subfloor must be even, flat, dry and variations should not exceed 3 mm in 2 m (0.12 in 6.6 feet)
  • All type of hard subfloors must be dry (concrete screeds < 2.0 %; anhydrite screeds < 0.5 % - CM instrument)

Moisture Protection:

  • All types of subfloors require insulation against moisture
  • Use Polyethylene (PE) film with minimum thickness of 0.2 mm = 6 mils (.008 inches)
  • On ground/basement subfloors we recommend laying 2 PE film layers crossways for better protection. Lay the PE film, allowing for at least an 8 inch overlapping and tape. Turn the PE film upward 5 cm along the walls. Trim only after the base boards are attached.

Radiant-Heated Subfloors:

  • Subfloor surface temperature must not exceed 80 degrees Fahrenheit
  • For detailed information, follow instructions of the subfloor heating system manufacturer/contractor or contact your supplier
Preventive Care:
  • If work activity will take place in the room where the floor is installed, protect with craft paper, plywood or hardboard
  • Do not drag furniture across the floor, use felt pads on chair and furniture legs
  • Place quality walk-off mats at all entrances to retain tracked in dirt, grit and moisture, never use latex or rubber backed mats as they can permanently stain the floor
  • Avoid moisture on the floor
  • Ideal and proper room conditions are 35-65% relative humidity at 68F. If necessary use a room humidifier to manage the relative humidity level on a consistent basis
  • Cork as a natural material, tends to fade when exposed to sunlight, use blinds, curtains or other sun screening system to minimize this effect
  • Cork Floating floors are intended for indoor use only
  • Cork flooring products are based on natural materials, and will expand and contract through heating and non-heating seasons, thus experiencing some separation between the planks/tiles at different times during the year. Such separations are not considered a product defect
