Quick-Step Linesse Installation



Unilink® is a revolutionary system for installing laminate floors without using glue. The panels can be simply clicked together thanks to the ingenious shape of the tongue and groove. 

Tools for installing the floor
For best results, it is essential that you follow the installation instructions exactly. Besides the regular tools for installing laminate floors (i.e. hammer, saw,
pencil, ruler) you will also need the following accessories:

- installation kit (crowbar (pullbar), spacers (1-8 mm / 0,039”-0,315”) and Unilink®-adapted tapping block)
- underlayment system (Quick•Step® screen)
- maintenance kit

The use of accessories other than the Quick•Step® accessories might cause damage to the Quick•Step® floor. In such case the warranty provided by
Quick•Step® will be void. We therefore advise to use only Quick•Step® accessories as these have been especially designed and tested for the use with
Quick•Step® floor panels.
Of course we also need to saw the panels. To obtain a clean cut, the pattern side should face down when you use a jigsaw or sabre saw and up for all
other types of saws.


8 Focus points
1. Thanks to the Unilink® system, the floor floats and is installed without glue. You can walk on the floor during and immediately after installation.
2. Check all panels in daylight before and during installation. Defective panels must never be installed.
3. The floor should preferably be installed parallel to how the light enters the room. The ideal conditions are 15-20°C (59-68°F) at a relative humidity
of 50-60%.
4. Let the panels acclimatize for 48 hours in the unopened packaging at the normal room temperature, in the middle of the room where the floor is to
be installed.
5. Room humidity can vary according to the season, so it is vital that the floor is able to expand and contract. For this reason, make sure you leave an
expansion gap of minimum 8 to 10 mm (5/16” to 3/8”) on all sides of the floor, around pipes, thresholds, under doors and around any fixed / stationary
objects (floor vents, kitchen islands, etc… )
6. Large rooms must have expansion gaps every 13 m (40 feet) width- and length- wise. It is recommended to provide an expansion gap between
different rooms (e.g. under the door). Expansion gaps can be finished by means of a T-molding that is attached to the subfloor.
7. Ensure that the end gaps of the panels in two successive rows are never in line. Always ensure that the gaps are staggered by at least 10 cm / 4 inches.
8. We recommend you purchase a few extra cartons of flooring. This will be useful to you if you have some damaged pieces, miscalculate the size of the
room or miss cut some pieces. This also will help you if your floor needs a repair but your product is no longer manufactured.


Preparing the room

- Check that the doors can still open and close after the floor and underlayment have been installed (minimum + 1 cm (3/8”))
- Check whether the old molding can be removed. You can also leave the wall base and finish the floor with Quick•Step® profiles.
- Make sure the subfloor is flat. Any unevenness greater than 2 mm (1/16”) over the length of 1 meter (40”) must be smoothed out.
- Make sure the subfloor is clean and dry:


New Construction:
- A new concrete floor must dry at least 1 week per 1 cm (3/8”) thickness up to 4 cm (1-1/2”). Thicknesses over 4 cm (1-1/2”) require twice as much
drying time. For example, a 6 cm (2-1/2”) concrete subfloor must dry for at least 8 weeks. The moisture content must be less than 2.5% (CM method)
or less than 5 lbs/24 hours per 1000 sqft (Calcium chloride method ASTM 1869).
- If there is underfloor heating, the subfloor must not exceed 28°C (84°F) and the moisture content must be less than 1.5% (CM method). You do need
to follow special installation instructions. Please ask your dealer for more information.

- Remove any damp-open floor covering (carpet, needle felt, etc.) first.
- Damp-sealed floor covering (PVC, linoleum, VCT, etc.) does not have to be removed.

- Remove any existing floor covering first.
- Make sure the plank floor is stable. Nail down any loose parts and apply a levelling layer (Quick•Step® foam underlay) if necessary.
- Install the Unilink® panels crosswise to the direction of the existing subfloor.
- It is necessary that the crawl space under the plank floor is sufficiently ventilated. Remove any obstacles and provide sufficient ventilation (minimum
4 cm² of total ventilation holes per meter (40”) of floor). The moisture content of the wood may not exceed 12%.

Installing the floor
- First install the Quick•Step® Screen underlayment, per width and gradually as you progress. Let the membrane run up the wall a bit before cutting to size.
With Unilink® the first floorstrip is affixed to the underfloor panel. The two other strips are clicked into the first strip. First slide the strips, then cut the panel.


Begin the first row with the first panel. Don’t forget to saw off the tongues of the first strips of the first row.

While making sure that the panels are in line, click the second panel with the first strip in the first strip of the already installed panel.

Start to cut a new panel for the second row in a different staggering as the first one and use the remainder of the first row to begin the third one.


  Step 2 – Completing the floor Push the installed floor with the cut off sides against the wall and insert spacers from the installation kit between the panels and the wall to obtain expansion gaps of 8 to 10 mm in width.

When cutting to size the last row, make sure to account for the 8-10 mm expansion space to the wall.


  Obstacles   Pipes Install the planks so that the pipes in the row fall exactly in line with the short end joints of two planks. The hole you draw in the planks should have an extra 20 mm in diameter from the actual pipe to allow for the expansion. After clicking the planks together, drill the hole, making sure that its center is marked by the joint after which the planks can be installed in the floor.


Under door frames When cutting the planks to size, make sure that there is a 10 mm expansion joint under the door. In this type of space where the angling method cannot be used, use an adapted tapping block or a crowbar and hammer to join the planks together.


  Step 3 – Finishing the floor

  • Remove all the spacers.
  • Make sure to install the molding on the membrane that runs up the wall from under the floor, and never on the floor so as the floor can expand under the molding.
  • Use rosettes or Quick Step kit to give the finishing touches around pipes.
  • Quick Step kit can be used to fill extension gaps in those spaces where profiles or skirting cannot be used. 


  • The furniture and chair legs must have proper felt or plastic caps for protection.
  • Use a suitable door mat to avoid bringing dirt, water and sand inside.
  • Make sure that the wheels of office chairs and seats are soft, suitable for laminated floors and use desk mats.
  • The minimum accepted level of humidity is of 50% and using a humidifier can help you maintain that level.
