3. Make sure the panels are mixed sufficiently when you install them so that you do not end up with too many

identical, light or dark panels next to each other.

4. Check all panels in daylight before and during installation. Defective panels must never be used.

5. 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%.

6. Under normal conditions*, Mohawk® flooring panels requires no acclimation period. Outside of the normal

conditions, let the planks acclimate 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. *Normal conditions means a difference of no more

than 60°F and 20% relative humidity between the stocking/transportation environment of the flooring and the

final installation environment of the flooring.

7. Room humidity and temperature 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 a minimum expansion joint of 8 to 10mm (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..).

8. Large rooms must have expansion joints every 13m (40 feet) width-wise to the panels and every 13m (40

feet) length-wise. We recommend having an expansion joint between different rooms (e.g. under the door).

Expansion joints can be finished by means of a molding that is attached to the sub-floor.

9. Ensure the end joints of the panels in two successive rows are never in line. Always ensure that the joints are

staggered by at least 15cm / 6 inches.

10. 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

+1cm (3/8”)).

- Check whether the old molding can be removed. You can also leave the wall base and finish the floor with

Mohawk® flooring profiles.

- Make sure the sub-floor is flat. Any unevenness greater than 2mm (1/16”) over the length of 1 meter (40”)

must be smoothed out. It is vital that you use an underlayment to smooth any unevenness in the base floor.

The specially designed Mohawk® flooring underlayment has a damp-proof, insulating, noise-reducing and

leveling function. The smooth top surface makes installing the floor panels easier and ensures ample

expansion afterwards. You can find more information about Mohawk® flooring underlayment and how to

install them on the underlayment packaging or at your dealer.

- Make sure the sub-floor is clean and dry.

CONCRETE SUBFLOOR:

New Construction:

- A new concrete floor must dry at least 1 week per 1cm (3/8”) thickness up to 4cm (1-1/2"). Sub-floors thicker

than 4cm (1-1/2") require twice as much drying time. For example, a 6cm (2-1/2") concrete sub-floor 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 sq ft (Calcium chloride method ASTM 1869).

- If there is under-floor heating, the sub-floor must not exceed 28.8°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.

Renovation:

– Remove any damp-porous floor covering (carpet, needle felt, etc.) first.
