laminate is sealed to the counter top surface, trim the
edges by using either a router with a special guide or a
small, block plane. If you want to bevel the countertop
edge, use a mill file.
Seabees use many different types of adhesives in
various phases of their construction projects. Glues
(which have a plastic base) and mastics (which have an
asphalt, rubber, or resin base) are the two major
categories of adhesives.
The method of applying adhesives, their drying
time, and their bonding characteristics vary. Some
adhesives are more resistant to moisture and to hot and
cold temperatures than others.
SAFETY NOTE: Some adhesives are highly
flammable; they should be used only in a
well-ventilated work area. Others are highly
irritating to the skin and eyes. ALWAYS
FOLLOW MANUFACTURERS INSTRUC-
TIONS WHEN USING ADHESIVES.
The primary function of glue is to hold together
joints in millwork and cabinetwork. Most modern glues
have a plastic base. Glues are sold as a powder to which
water must be added or in liquid form. Many types of
glue are available under brand names. A brief
description of some of the more popular types of glue is
Polyvinyl resin, or white glue, is a liquid that comes
in ready-to-use plastic containers. It does a good job of
bonding wood together, and it sets up (dries) quickly
after being applied. Because white glue is not
waterproof, it should not be used on work that will be
subjected to constant moisture or high humidity.
Aliphatic resin, or yellow carpenters glue, is a
liquid that comes in ready-to-use plastic containers.
Yellow glue is somewhat stronger than white glue and
is more resistant to moisture, lacquers, and solvents.
Urea resin is a plastic-based glue that is sold in a
powder form. The required amount is mixed with water
when the glue is needed. Urea resin makes an excellent
bond for wood and has fair water resistance.
Phenolic resin glue is highly resistant to
temperature extremes and water. It is often used for
bonding the veneer layers of exterior grade plywood.
Resorcinol glue has excellent water resistance and
temperature resistance, and it makes a very strong bond.
Resorcinol resin is often used for bonding the wood
layers of laminated timbers.
Contact cement is used to bond plastic laminates to
wood surfaces. This glue has a neoprene rubber base.
Because contact cement bonds very rapidly, it is useful
for joining parts that cannot be clamped together.
Mastics are widely used throughout the
construction industry. The asphalt, rubber, or resin base
of mastics gives them a thicker consistency. Mastics are
sold in cans, tubes, or canisters that fit into
hand-operated or air-operated caulking guns.
These adhesives can be used to bond materials
directly to masonry or concrete walls. If furring strips
are required on a wavy concrete wall, the strips can be
applied with mastic, rather than by the more difficult
procedure of driving in concrete nails. You can also
fasten insulation materials to masonry and concrete
walls with a mastic adhesive. Mastics can also be used
to bond drywall (gypsum board) directly to wall studs.
They can also be used to bond gypsum board to furring
strips or directly to concrete or masonry walls. Because
you dont use nails, there are no nail indentations to fill.
By using mastic adhesives, you can apply paneling
with very few or no nails at all. Wall panels can be
bonded to studs, furring strips, or directly against
concrete or masonry walls. Mastic adhesives can be
used with nails or staples to fasten ply-wood panels to
floor joists. The mastic adhesive helps eliminate
squeaks, bounce, and nail popping. It also increases the
stiffness and strength of the floor unit.
