Experienced professional installers of
hardwood flooring will find themselves right at home installing
bamboo hardwood flooring. Although every installer has a style of
his own guidelines for installing bamboo flooring are the same as
those recommended for installing hardwood flooring in general. Those
recommendations have been developed over several years by The National
Wood Flooring Association, The National Oak Flooring Manufacturers
Association and The Hardwood Council.
Another good source of installing and
finishing information can be found online at Wood Floors Online.
Some installation Basics
Designers, architects, builders or homeowners in a position of overseeing
an installation by professional installers should keep in mind some
simple "rules" that apply in the laying of any hardwood
flooring.
Make sure the sub floor is dry, level
and free of squeaks. Measure the moisture content of sub floor in
several locations. Unpack the bamboo flooring and let it age in
the room for a week to ten days.
All wood flooring, including bamboo flooring,
displays some slight color variation board to board. Unpack and
lay out ahead of the installer four or five cartons of bamboo flooring
so that color variations can be mixed in a random pattern and not
consolidated in a single area.
Begin laying the bamboo flooring from
the end of the room that is aesthetic focal point. This way, the
partial board that has to be top nailed or other corrections due
to actual geometry of the room, occur at the visually "unimportant"
end of the room.
Make certain that sufficient expansion
space is left at the perimeter of the installation. In climate areas
where the humidity of the room varies seasonally very little, a
minimum expansion space of 6.35mm is recommended.
In areas where humidity variation is
high from season to season, as in south-central United States, an
expansion space of 19mm is suggested. The bamboo hardwood flooring
behaves in a similar fashion to other hardwoods; your local professional
installer should be your "expert" source on this as well
as other installation and finishing questions.
The end joints of the bamboo flooring
should be randomly positioned one to another to avoid visually symmetrical
patterns like "stair casing".
Some finishing suggestions
We recommend three sandings. A 60 grit sanding, following by 100
grit polishing and then a "buffing" 150. With the solvent-based
coatings for all types of floors is better from a wear standpoint.
For those non-professionals who want
to acquire more solid oversight-skills for flooring installation
and finishing techniques, we recommend reviewing "Hardwood
Floors. Laying, Sanding and Finishing" by Don Bollinger. This
is an excellent, clearly-written, illustrated resource for layman
and professional alike from the Fine Homebuilding series published
by The Taunton Press in Connecticut.
In finishing bamboo flooring, we have
had good success with solvent-based polyurethane from Bona Kemie;
one sealer coat followed by a buffing to smooth the grain and then
two top coats. A water-based urethane is often preferred because
the odor during installation is minimum.
