Routing Seams
IMPORTANT:
> Rout approximately two-thirds of the product.
> Do not rout into the backing.
> Always practice routing and heat welding on a scrap piece of material to ensure proper
routing depth, temperature setting and speed.
> When using a contrasting colored weld thread, all
seams must be routed with an electric router.
Hand Router
Seams are underscribed or double-cut to produce a
net fit (no space).
FIG.51: Position the hand router so that it is centered
directly over top of the seam cut. Using a short
straightedge (i.e., carpenters square) as a guide pull
the router using firm pressure. Rout approximately
two-thirds of the product. Router must be centered
over seam cut in order to remove an equal amount of
material from each side. Practice on a scrap piece of
flooring before routing actual seam.
Electric Router
Seams are underscribed and cut to produce a 1/64"
space. Before electric router can be used, each end
of the seam must be routed with the hand router
for a distance of approximately 6" to 8". Set the
blade depth approximately two-thirds of the product.
Practice on a scrap piece of flooring before routing
actual seam. Place electric router on floor. Line up
front and back tracking wheels in grooved area. Turn
router on and slowly push router along seam. Do
not apply excessive pressure. Inspect depth of rout
after 1 or 2 feet of operation and adjust if necessary.
CAUTION:
Never adjust blade while router is turned on or plugged into an electrical outlet.
Heat Welding Seams
With the heat weld method, a 4 mm vinyl thread and
the flooring material at the seam are heated to a
specific temperature, fusing the two together. Heat
welding shall be performed by a trained professional.
FIG.47: Apply adhesive over the exposed substrate
except for a 24" band centered beneath the seam.
Apply adhesive with a 1/32" deep x 1/16" wide x 1/32"
apart (0,8 mm deep, 1,6 mm wide, 0,8 mm apart)
notched trowel. Apply adhesive in a straight line
along folds in flooring.
After application of adhesive, slowly roll the flooring
back into position. When installing over a non-porous
surface, allow adhesive to dry until it is tacky to
the touch before positioning flooring. Dry time will
vary depending on the porosity of the substrate,
temperature and humidity. Avoid trapping air beneath
the sheet. Do not flop or drop the flooring into the
adhesive, as this may cause the flooring to shift or
cause air bubbles. Avoid trapping air under sheet.
Double-check seam overlap and make sure pattern
match is exact. Roll flooring in both directions with a
75 lb. sectional floor roller. Make sure no trapped air
remains between the flooring and the substrate. Do
not roll the last 6" to 8" along the adhesive line. This
will allow for easier pull-back of the second half of
material. A hand roller should be used in areas where
the large floor roller cannot reach. It is important that
the perimeter of the floor also be rolled.
Tarkett
®
recommends using the double-cut dry
method for cutting seams. Do not use the straight
edge and butt method.
FIG.48: Lay a straightedge along the center of seam
overlap or grout line. If grout line is 1/8" or less,
place straightedge along outside edge of grout line.
Using the straightedge as a guide, cut through both
sheets of flooring with a sharp, sturdy utility knife. Hold the knife straight up and down
at a 90° angle to produce a vertical cut. Do not tilt knife blade. Do not place a scrap piece
of flooring under seam overlap.
FIG.49: Lift top edge of flooring and carefully remove bottom selvage piece. Fold back
each sheet of flooring at the seam area to expose the substrate.
FIG.50: Fold back sheets at seam area to expose adhesive line. Apply adhesive to
remaining seam area. After adhesive has been given sufficient time to tack, position
seam and roll with a 75 lb. sectional floor roller. Do not compression-fit seams.
