Hardwood flooring installation
Robar Hardwood Flooring provides hardwood
flooring installation services for clients in Toronto, Mississauga
and GTA.
Before any hardwood flooring installation,
or laying any hardwood floor it is recommended to let the
material become acclimated to the conditions of the house.
Ideally the hardwood flooring should be ordered a few days
in advance before the installation and spread in the room
in which it is to be laid.
Hardwood floor is laid over a level, clean
board or plywood sub-floor. The sub-floor needs to be well
inspected. Any dips should be repaired by shimming between
the floor joists and the sub-floor. Loose boards should be
nailed or replaced, raised edges should be levelled and any
openings filled. Over a sub-floor a layer of building paper
is laid to make the floor draft-tight. This layer can also
help exclude moisture from below and smooth out slight irregularities
in the sub-flooring. A plank hardwood floor should not be
laid directly on top of a concrete slab. For this kind of
hardwood flooring installation a layer of plywood needs to
be installed first.
Hardwood strips are laid perpendicular to
the floor joists or wood sleepers. If an existing board
sub-floor
has been laid perpendicular to the joist the planks need to
be laid across the grain of the strips.
Since hardwood expands and contracts with
changes in humidity, a 1/2” gap is left between the
hardwood flooring and the wall around the perimeter of the
room. This gap is more critical parallel to the floor boards
since wood will expand and contract more across its grain
or across the width of the strips.
The first hardwood strip is placed 1/2”
from the wall with the grove edge facing the wall. It is face
nailed close enough to the grooved edge so that the nails
can be concealed by the base and the quarter-round. All other
nails go through the tongue at 45 degree angle every 10 to
12 inches. As the floor is laid, the lengths of planks are
selected so that end joints are well staggered and at least
6” apart from each other. The last strip is face nailed
just like the first strip. The expansion gap is covered by
baseboard and quarter-round (see diagrams).
