Step 1.1

SUB-FLOOR - CONCRETE

1) Insure that your sub-floor is clean, flat, smooth and level. Slopes of more than 5 mm over 2 meters or 1/4” over 6 feet must be levelled. Correct any changes in slope using a levelling compound. After levelling, wait at least 1 week to allow the compound to dry completely before laying your SEQUOIA floor.

2) Apply a dust-inhibiting sealant.

3) Lay a moisture barrier of 0.2 mm / 0.008” polyethylene plastic and overlap any edges by 200mm / 8”. Using the wide adhesive tape, seal the edges by taping along the entire seam.

4) Lay the moisture barrier up the walls 50 mm / 2”, to prevent moisture from penetrating the edges of the flooring.

5) Lay the polyethylene foam or other approved underlay over the moisture barrier. Tape the edges together using the wide adhesive tape, but do not overlap.

* Please skip this step if you have purchased
our laminate flooring with pre attached underlayment
such as our Palmbeach and Hampton collection.

Special notes:
1) On all concrete floors, the carpeting and underpadding must be removed to avoid possible humidity problems.

2) For floors with radiant heating make sure to turn down your thermostat to 15°C / 60°F at least 1 week prior to installation (do not turn off heating if the temperature outside is below freezing). Maintain the room temperature below 27°C / 80°F
