the laminate in other areas.
STEP 16
Remove the outer and inner templates.
STEP 17
Spray a solvent into the gulley on the remaining thin layer of wood.
Toulene or lacquer thinner are good products to use. Acetone may
also be used.
STEP 18
Care should be taken to apply solvent to the inside of the gulley and
let it soak towards the outside. Too much solvent on the outer

surface. Using a 1/2” wide chisel may be easier than a wider one.
Narrower chisels tend to offer more control than wider ones.

Using your chisel, remove all of the wood from the back of the laminate.

29
Clean the back of the laminate thoroughly using denatured alcohol
and a clean rag.
STEP 30
22
Clean the rim of the sink thoroughly using denatured alcohol and a
clean rag.
STEP 31
23
Prepare to glue the sink to the back of the laminate. You will need a
10:1 mix gun and a 10:1 two part solid surface seaming adhesive
cartridge. Use a dark brown color as this will most closely match the
brown laminate backing.
32
STEP 24
Insert the adhesive cartridge into the mix gun.
STEP 21
33
Purging of the tube is important to ensure both catalyst and adhesive are dispensing. Simply squeeze out a small amount to ensure
both are flowing.

22
Place the sink carefully onto the back of the laminate.
STEP 39
23
Measure from the front of the countertop to the bowl wall on both
ends to ensure the sink is straight.
40
STEP 24
An even gap should be visible around the perimeter of the sink rim.
STEP 21
41
Seaming adhesive should be visible oozing out on the inside of the
bowl wall around the inside perimeter of the sink.
STEP 42
22
Leave the sink and countertop for 30 to 40 minutes to allow seaming
adhesive to fully cure.
STEP 43
23
Some installers opt to use no weight during the curing process, relying solely on the sink’s weight. Others prefer to use about 5lbs to
10lbs per bowl.
44
STEP 24
Once the seaming adhesive has fully cured, add your undermount
support strips. Cut 1-ϭͬ Ϯ͟ ƚŽϮ͟ ǁ ŝĚĞƐƚƌŝƉƐŽĨƉĂƌƟĐůĞďŽĂƌĚƚŽƵƐĞĂƐ
support strips.
Begin by placing the strip on the underside of the countertop and
sliding it over the rim. Take note whether the wood strip hits the rim

side of the wood substrate and the underside of the sink rim are
flush and level. If the rim is higher than the substrate, use a belt
sander to sand it flush to the substrate.
STEP 46
22
Apply some wood glue to the strip of wood and staple in place.
STEP 47
23
If the sink rim is lower than the substrate, mix up some Bondo body
filler and place some on the rim of the sink. This will fill the void
once the support strip is stapled in place.
48
STEP 24
Apply some wood glue to the wood support strip.
STEP 21
49
Staple the wood support strip into place. The Bondo applied to the
rim will spread and fill the gap that existed between the rim and
wood strip.
STEP 50
22
Do not place wood support strips where they may interfere with
faucet placement.
STEP 51
23
Flip the countertop over.
52
STEP 24
Final trimming of the laminate will be accomplished
with a bevel bit. This bevel bit has a 10° ĐƵƫ ŶŐĂŶŐůĞ
and an 1/8” oversized nylon bearing. This custom router bit can be ordered from your Karran Sinks distributor.
Place the bit in an adjustable depth plunge router.
Lower the bit so that the bearing is running just below
the laminate and the oozing seaming adhesive.

pass.
The goal is to trim the laminate as close to the stainless steel wall as
possible without touching the wall with the router bit.
STEP 55
23
Adjust the depth of the router bit slightly lower so as to achieve a
closer cut of the laminate to the sink bowl wall.
56
STEP 24
Make a second pass. Carefully examine the amount of overhang

on the front edge of the sink. This is the least visible area to the
homeowner should any repair work be needed. Should the router
bit scuff the stainless steel wall, use a coarse grit sandpaper to hand
sand the area parallel to the grain on the sink wall. Then move to

ish of the stainless steel.
STEP 58
22
Removing the last remaining overhang of laminate and seaming
adhesive may be accomplished by hand filing. Use an assortment of
Į ůĞƐŝŶĐůƵĚŝŶŐŇĂƚĂŶĚƌŽƵŶĚĮ ůĞƐƚŽŚĂŶĚĮ ůĞƚŚĞůĂŵŝŶĂƚĞƵŶƟůŝƚŝƐ
flush with the bowl wall.
STEP 59
23
File the edge of the laminate to the point that the stainless steel wall
starts to show through the glue line. Remaining seaming adhesive on
the bowl wall will simply peel off.
60
STEP 24
Use a round file in the corners.
STEP 21
61
Some final hand sanding with a fine grit sandpaper will be needed to
completely smooth and blend the laminate edge and stainless steel
sink wall.
STEP 62
22
Use a fine grit flap wheel (180 grit) in a drill to restore horizontal

the drill horizontal and do not move it up and down.
Once blended, wipe the sink and countertop clean. To give the
finished sink a lustrous glow, wipe the sink down with WD-40.
STEP 63
23
Your sink is now seamlessly installed in your laminate countertop.
64
STEP 24
When installing faucets, these will be installed directly into the
countertop. Use a 1-1/2” hole saw to drill the necessary holes.
STEP 21
65
Take the FHSR (Faucet Hole Seal Ring) supplied with your sink and
place a bead of silicone around the base of it.
STEP 66
22
Slide it into each drilled hole.
STEP 67
23
Wipe up excess silicone with a wet rag.
