LAMINATE FLOOR
Preparing the Room
• Mix planks from different cartons when installing to maximize the natural look of the oor.
• Check that the doors can still open and close after the oor has been installed (minimum 3/8-inch).
• Check whether the existing molding can be removed. You can also leave the wall base and nish the oor with accessory proles.
• Make sure the suboor is at. Any unevenness greater than 1/16-inch over the length of 40 inches must be smoothed out.
• Make sure the suboor is clean, dry and stable.
• Flooring may be installed over radiant heat systems following special installation instructions. Contact your retailer for further details.
Concrete Suboor
The moisture content of the concrete must be less than 5 lb/24 hr per 1000 sq ft (ASTM F1869) or <80% with an in situ probe (ASTM F2170). Always use
underlayment and a minimum 6-mil poly moisture barrier if a moisture barrier is not attached to the underlayment.
New Construction:
• A new concrete oor must dry at least 1 week per 3/8-inch thickness up to 1-1/2 inches. Thicknesses over 1-1/2 inches require twice as much drying
time. For example, a 2-1/2-inch concrete suboor must dry for at least 8 weeks.
Renovation:
• Remove any damp-porous oor covering (carpet, needle felt, etc.) rst.
• Damp-sealed oor covering (PVC, linoleum, VCT, etc.) does not have to be removed.
Wooden Suboor
• Remove any existing damp-porous oor covering rst.
• Make sure the sub oor is stable. Nail down any loose areas and apply a leveling layer if necessary.
• Install the Uniclic
®
planks crosswise to the direction of the existing suboor.
• For installations over a crawl space, the soil in the crawl space must be covered by a 6-mil non-recycled polyethylene lm with seams overlapping at
least 8 inches. In addition, vents should be located throughout the foundation. They must provide good cross ventilation and no dead air space. There
must be minimum vent openings equal to 1.5% of the square footage within the crawl space. For example, 100 sq ft of crawl space must have at least
1.5 sq ft of open vents.
• The moisture content of the wood may not exceed 12%.
Installing the Floor
• First install the underlayment. See Diagram 3A. If the underlayment is pre-mounted on the planks, use a damp-proof moisture barrier with water
resistant adhesive tape. For concrete, let the moisture barrier run up the wall before cutting to size. A molding will be attached to this later. For wood,
cut the moisture barrier 1 inch from the wall.
• Begin the rst row with a whole plank. First saw off the tongue on both the long and the short sides. See Diagram 3B.
• Place the planks with sawn-off sides against the walls. Put spacers from the installation kit between the planks and the wall. This will ensure that your
expansion joint is wide enough: 3/8-inch. See Diagram 3C.
• The diagrams indicate where the Uniclic
®
planks are clicked together by angling up and down or where they are tapped together at. Follow the
diagrams precisely. See Diagrams 4A –4F. For better results, the oor should be installed with a staggered random length for the starting planks in each
row - be careful not to create a repeating pattern. For example, start the rst row with a whole plank, second row with 1/3 of a plank, third row with
2/3 of a plank, then a whole, then 1/2, then 1/4, then back to whole, then short, then medium, etc. Alternating the length of the starting plank on each
row will avoid creating a zigzag or stair step pattern in the oor.
