Kitchen & Bath: Laminate Countertop Edge Options
If you’re not installing one of those red-hot countertop
materials like solid-surfacing, stone, or butcher block,
chances are you’re working with high-pressure plastic
laminate — still the dominant countertop material. No
matter which material you or your client chooses, every
countertop has an edge that can and should be turned to
advantage.
A square edge is a workmanlike option, but it’s not the
best or only possibility. Square edges are sharp and
unforgiving, easily damaged by impact, and generally
don’t say much about craftsmanship or design. If
you’re working with solid-surfacing or stone,
you’re limited only by your router bit collection. But if
you’re dealing with laminate, you need something
more.
The Thin Brown Line
Those who choose plastic laminate for its economy, endless
color and pattern options, and easy maintenance want to see it
as seam-free as possible. Clients often complain about the dark
line at the edge of a common plastic laminate top. Fabricators
have developed a number of clever techniques for disguising
that line, the simplest of which involves capping the edge with
an applied hardwood face band. A wood edge can easily be shaped
and rounded. You can buy ready-made wood edging in a number of
profiles, including bullnose, bevel, or face-routed to receive
a solid-surface, metal, or wallpaper accent stripe (see Figure
1). Not everyone likes the wood look, however.
Beveled laminate edging effectively eliminates the dark stripe
and upgrades the appearance of a laminate top, but it’s
somewhat demanding to apply. If the alignment is even slightly
off after the glue dries, you’re left with a knife- sharp
edge and no happy means of adjustment. The margin of error is
somewhere around 2/1,000 inch. Sand the edge a little too much
and you’re back to the dark line you wanted to lose in
the first place. Beveled laminate edges are available with and
without an interlocking tongue for alignment. If you’re
totally confident in your router skills, a tongued strip and
grooved counter edge provide a strong, self-aligning match. But
all it takes is a piece of sawdust under the router base, a
micro dip in the surface, or a wobbly wrist to mess you up. A
smooth-backed strip is plenty secure if you thoroughly coat the
mating surface with a good yellow wood glue (aliphatic resin)
and temporarily secure the strip to the countertop with banding
tape. You can feel the edge as you go, and you’ll have
several minutes to adjust the alignment before the glue starts
to set. If necessary (and if you’ve got the 2/1,000
touch), you can perform miniscule touch-ups with 220-grit
sandpaper.

Kuehn Bevel is the wood edge, with a recessed face ready to
receive any number of accents, including solid-surface strip,
metal strip, or wallpaper.
Hybrid Edge
My favorite laminate edge treatment (for the imperfect world we
live in) is the Gem-Loc. This edge combines a laminate face
with rounded, solid-surface corners, creating a softer
transition than a beveled edge (Figure 2). The Gem-Loc is
available with and without an installation tongue; an important
difference is that you deliberately install the strip a few
thousandths proud of the countertop surface, then file it
perfectly flush. The manufacturer stocks over 130 solid-surface
colors in four major brands — Corian, Surell, Gibraltar,
and Fountainhead — and all standard laminate colors in
Formica, Wilsonart, Pionite, and Nevamar. The possible color
combinations are claimed to be in the vicinity of 113,500. You
can also have a custom edge quoted, using nonstock laminates
and solid-surface colors of your specification. Backsplash cap
is available, but not the backsplash itself. The company will
ship any order, small or large, to most locations for a flat
$34 fee within about a week.

thousands of combinations of laminate and solid-surfacing
colors. The rounded edge is designed for simple, seamless
application.
Kuehn Bevel and Wilsonart both offer bevel laminate,
solid-surface, and wood edging options. Kuehn’s
7/16-inch-thick solid-surface edge is available in eight
19/16-inch-wide profiles in 12-foot lengths (Figure 3). The
edge has a continuous 5/32 x 1/4-inch groove in the back to
receive an “O”-size joining biscuit. It must be
bonded to the countertop using a special adhesive equivalent to
E-6000 (Eclectic Products, 995 S. A St., Springfield, OR 97477;
800/767-4667), a clear, silicone-based product. The bonding
procedure is otherwise similar to that for the other edge types
— that is, cut, glue, position, and tape.
Kuehn offers the sage advice that you should seal the underside
of the countertop above and near the dishwasher with a
waterproof sealer — polyurethane or thinly spread
silicone caulk, for example — to avoid steam or moisture
damage to the edge and substrate.
Figure 3.Solid-surface edging offers a durable,
attractive treatment with near-foolproof application and custom
corner profile capability. This option is adaptable to most
countertop materials, including high-pressure
laminate.
Preparation
To prepare the countertop for edging, first laminate the top,
then rout the edges true using a straight carbide cutter guided
along a straightedge. This will start you off with a
factory-grade edge, essential for near-seamless edging results.
And it’s best to trial-fit and fine-tune all the edging
pieces first, temporarily holding them in place with tape,
before committing to the adhesive.
