PRIOR TO INSTALLATION
•
•
•
Carefully check flooring material for any defects. Contact your supplier immediately if any defect is found.
Remove quarter round, baseboard molding or cove base.
Undercut doorway moldings the thickness of the flooring.
WOOD SUBSTRATES
Wood floors must be double construction with a minimum thickness of 1”. Top layer of plywood shall be ¼” minimum thickness underlayment grade
plywood. Tarkett recommended underlayments include APA Underlayment Grade Plywood A-C, B-C or C-C Plugged, ACCU-PLY,
SurePly, TECPLY, ULAY, C.S.A. (CanPly) and Proboard
CONCRETE SUBSTRATES
Flooring may be installed over on grade, above grade or below grade concrete subfloors. Concrete floors shall be constructed in accordance with
the American Concrete Institute (ACI) 302.1 Guide for Concrete Floor and Slab Construction. Concrete shall be finished and cured according to ACI
and have a minimum compressive strength of 3500 psi. Floors must be free of any sealers, curing, hardening or parting compounds that would
adversely affect the adhesive when using the Full Spread Installation System. Installation of moisture vapor barrier is recommended prior to pouring
of on or below grade slabs. Moisture vapor transmission shall not exceed 3 lbs./1000 sq.ft./24 hours per ASTM F-1869 (Anhydrous Calcium
Chloride Test). Moisture may also be tested according to ASTM F 2170 (Standard Test Method for Determining Relative Humidity in Concrete Floor
Slabs Using in situ Probes). When tested according to this method, the internal relative humidity shall not exceed 75%.
Flooring may be installed over gypsum based underlayments when using the Glueless Installation System.
EXISTING FLOORS
If using the Glueless Installation System, flooring may be installed over two layers of non-cushioned existing resilient flooring. When using the Full
Spread Installation System, Flooring may be installed over a single layer of existing non-cushioned resilient flooring only. Check existing floor for
any curled areas around the perimeter or at seams and repair if necessary. Use of a good quality, cementitious based embossing leveler to fill and
level any irregularities wider than 1/4” or height differences greater than 1/16”. An embossing leveler must be used for all full spread installations.
SUBSTRATE PREPARATION
•
•
•
•
All substrates must be dry, clean, smooth and level.
When using the Glueless Installation System, flooring will bridge minor imperfections in the substrate. However, any joints or cracks wider than
1/4” or height differences over 1/16” shall be leveled with a cementitious based patching compound.
When using the Full Spread Installation System, fill and level all plywood seams and concrete cracks, construction joints, control joints,
depressions, grooves or other irregularities. Use a cementitious based patching compound.
Sweep and/or vacuum substrate to remove all dust and debris.
WARNING: Do not sand, dry sweep, dry scrape, drill, saw, beadblast or mechanically chip or pulverize existing resilient flooring, backing,
lining felt or asphaltic “cutback” adhesive. These products may contain asbestos fibers or crystalline silica. Avoid creating dust.
Inhalation of such dust is a cancer and respiratory tract hazard. Smoking by individuals exposed to asbestos fibers greatly increases the
risk of serious bodily harm. Unless positively certain that the product is a non-asbestos containing material, you must presume it
contains asbestos. Regulations may require that the material be tested to determine asbestos content.
GENERAL INFORMATION
•
•
•
•
•
Cut orders may be rolled face in (back rolled) on a sturdy core.
Unroll the flooring in the room and allow it to relax approximately 20 minutes. Material shall be lying completely flat before fitting.
Room temperature, flooring and adhesive shall be maintained between 65° - 85° F for 48 hours before, during and after installation.
Undercut door moldings to allow flooring to fit loose and freely under the molding.
There is no maximum length for the installation of Berkshires. However, long lengths of flooring may have a tendency to bow or twist during
layout or positioning. Use caution to insure that the material is lying completely flat and is aligned squarely within the room before final fitting
and/or cutting of seam.
•
•
•
•
•
•
When using the Glueless Installation System, leave a 1/4” space between flooring and all verticals (i.e. walls, cabinets, pipes, etc.).
Leave a 1/2” space for floors installed over wood substrates that have a potential of being exposed to high moisture levels (i.e. crawl
spaces).These areas may also be fully adhered with recommended adhesive.
Do not install cabinets on top of flooring when using the Glueless Installation System.
DO NOT PERIMETER BOND BERKSHIRES.
Use Tarkett Floating Seam Tape if seams are required.
If an installation requires the floor to be net fit, flash coved, installed on steps or if the flooring will be subjected to heavy caster action
exceeding the static load limit (i.e. portable dishwashers, microwave carts, wheel chairs, etc.), fully adhere the flooring with recommended
adhesive.
GLUELESS INSTALLATION SYSTEM
•
•
•
Measure the room and precut the flooring allowing extra material for trimming.
Unroll the flooring and position in the room so the pattern is aligned squarely with walls.
Allow flooring to relax for 20-30 minutes. Material shall be lying completely flat before fitting.
•
Using a sharp, sturdy utility knife, make relief cuts at inside and outside corners.
•
Trim the flooring around the perimeter of the room. When fitting flooring, leave a 1/4” space between flooring and all verticals (i.e.
walls, cabinets, pipes, etc.).
•
Slide flooring underneath the undercut door casings.
SEAMING
•
•
•
After first piece of flooring is positioned, cut second piece of flooring. Be sure to allow extra material for pattern match.
Align match marks along factory edge accordingly. Overlap seam edges and obtain exact pattern match.
Place masking tape at seam overlap to prevent flooring from moving.
•
•
•
Fit second piece of flooring. Remember to leave a 1/4” space between flooring and all vertical objects.
Seams are cut using the double-cut method.
Lay a straight edge along center of seam overlap or grout line. Using the straight edge as a guide, cut through both sheets of flooring with
a sharp, sturdy utility knife held to produce a vertical cut. Do not tilt knife blade. When installing over an existing floor, do not cut into the
existing floor. Lift top edge of flooring and carefully remove bottom salvage.
•
Use Tarkett Floating Seam Tape when seams are required. Fold back one sheet of flooring at the seam area to expose the substrate.
Position Tarkett Floating Seam Tape so that it is centered under the seam cut. Starting at one end of the seam, carefully remove one half
of the release liner from the Floating Seam Tape and position first half of flooring. Reposition second piece of flooring. Make sure seam is
properly aligned. Remove second half of release liner, position flooring and roll seam area thoroughly.
•
Seal seams with recommended seam sealer. Protect seam from traffic for a minimum of 8 hours.
FULL-SPREAD INSTALLATION SYSTEM

•
Using a sharp, sturdy utility knife, make relief cuts at inside and outside corners.
•
•
Trim the flooring around the perimeter of the room.
•
After flooring has been fit, fold or loosely roll the flooring back to expose one half of the subfloor. Make sure the sheet does not move or
shift. Apply recommended adhesive evenly over substrate. Apply adhesive according to manufacturer’s recommendations. Roll flooring
with a 75-100 lb. sectional floor roller.
SEAMING
•
•
Cut and position second piece of flooring. Be sure to allow extra material for pattern match.
Align match marks along factory edge accordingly. Overlap seam edges and obtain exact pattern match. Place masking tape at seam
overlap to prevent flooring from moving. Fit second piece of flooring.
•
•
After second piece of flooring has been fit, remove masking tape from seam area. Mark the substrate along factory edge with a pencil.
•
Fold or loosely roll back each piece of flooring lengthwise to expose the entire seam area. Apply recommended adhesive over the exposed
substrate. Apply adhesive according to manufacturer’s recommendations. Roll flooring in both directions with a 75lb. sectional floor roller
except for 6” on either side of the seam.
•
•
Lay a straight edge along center of seam overlap or grout line. Using the straight edge as a guide, cut through both sheets of flooring with
a sharp, sturdy utility knife held to produce a vertical cut. Do not tilt knife blade. When installing over an existing floor, do not cut into the
existing floor. Lift top edge of flooring and carefully remove bottom salvage. Position flooring and roll seam area thoroughly.
•
•
Fold or loosely roll back the second half of flooring on each side. Apply adhesive to remaining areas, position flooring and roll with a 75-100
lb. sectional floor roller.
•
Seal seams with recommended seam sealer. Protect seam from traffic for a minimum of 8 hours.
FINISHING THE JOB
•
Carefully inspect for any fullness in the flooring. Re-trim if necessary. Flooring shall be lying flat. It is recommended that all exposed edges
be covered. Install wood moldings or cove base around the perimeter to cover the space. Do not fasten or nail moldings through the
flooring. Fasten into the wall.
•
•
•
Use transition moldings at doorways or where the new flooring meets an existing floor. Do not nail or fasten the molding through the
flooring. Transition moldings shall be fastened to the substrate. If a transition molding must be installed directly on top of flooring. Mark on
the flooring where each fastener will be positioned. Drill or cut a hole larger than the size of the fastener. This will allow for any type of
movement.
Do not move or roll furniture and appliances directly over floor. Always place plywood or hardboard panels on floor when moving furniture
or appliances.
Maintain post installation temperature between 55º F and 100º F. Maintain relative humidity between 40% and 70%.
CARE AND MAINTENANCE
•
•
•
•
•
•
•
Check furniture to be sure the legs are equipped with proper rests and are of sufficient size to prevent permanent indentations.
Sweep and /or vacuum any dirt or debris that can abrade or scratch the floor. Use a soft brush, dust mop or vacuum.
Light daily sweeping or vacuuming will help maintain the floors original gloss by removing any grit particles, which can affect the normal
gloss.
Wipe up spills promptly and thoroughly with a clean, damp cloth. Spills are easier to remove if wiped up immediately.
When necessary, wash the floor with a neutral floor cleaner.
Use non-staining walk-off mats at outside entrances to prevent dirt and debris from being tracked onto the floor. Discoloration of the
flooring may occur from rubber backings and dyes used in floor mats and rugs.
As with other household furnishings, repeated exposure to direct sunlight may cause bleaching or discoloration. When possible, close
drapes or blinds during peak sunlight hours to block direct sunlight.
