Laminate floors are meant to be floated over a variety of sub
floors and never secured directly to any substrate. In other words, the
laminate flooring just lays on top of the sub floor,
which can be wood, concrete, or an existing floor. This allows the laminate
flooring to expand and contract freely as the room environment changes.
Laminate floors come in planks and squares of various sizes and shapes. All
four sides of each plank have a tongue and grooved edge for locking them
together.
Many brands of laminate floors no longer require specials
glues at the tongue and groove joints. Many laminate floors now have some
sort of special glueless locking systems which makes installation much easier for doing it yourself.
There are also laminate floors which have the glue pre-applied along the
tongue and the glue is activated by touching the tongue with a damp sponge.
Many of the better grade laminate floors have all edges pre-sealed at the
factory to help prevent moisture from attacking the inner core structure.
Special polyurethane underlay is laid down prior to
installing laminate flooring. This helps the floor to float freely over the
top. Some more expensive underlayments are
available for reducing sound transmissions and restricting moisture from
wicking up.

Installation is done similar to hardwood flooring. Drying
laying several rows first and squaring up the rows in the room. Acclimating the planks to the room is also essential to
make the installation easier and to avoid planks bowing and cupping.
Glueless Laminate Floor Installation
Most laminate flooring manufacturers today offer gluess laminate floors. These floors do not require any
glue to lock the planks together and are often referred too as "clic-floors". The tongue and grooves are specially
designed to lock together and not come a part from foot traffic. Be sure to
read the manufacturer's recommeded installation
procedures before installing. (Note: The subfloor needs to fairly level (flat) in order for the planks to easily lock
together.)
Glued Laminate Floors
Below is a general outline of the various tools used to
install glued-together laminate flooring. Always follow the manufacturer's
installation instructions and use the manufacturer's recommended installation
tools.

1.
Glue - most laminate
floors require a special glue to secure the planks together and help seal
moisture from penetrating the core.
2.
Fillers & Sealants - some
laminate manufacturers have added color coordinating fillers and sealants.
The colored fillers are to fix seam gaps between planks and the sealant is
used around the perimeter where moisture may enter.
3.
Straps - straps work much
better than clamps at pulling plank rows together. Normally you need a
strap set for every four feet in the starter rows.
4.
Tapping Block - the tapping blocks
are used to lightly tap two planks together. Most blocks are
designed to fit a specific manufacturers tongue
and groove design.
5.
Wedges - the V-shaped
wedges are used to insure a minimum gap is left between the laminate floor
and all vertical walls. Consult manufacturer's installation for required
gap distances.
6.
Pulling Bar - the bar is used to
help pull two pieces of laminate together. Care must be used with these
bars so as to not chip the surface of the laminate plank.
