"Panelization"
"Panelization" is a condition where localized excessive
cracks develop between some strip flooring boards while adjacent boards
remain tightly bonded together with no apparent separations. "Panelization" (or "sidebonding")
is definitely not a new problem. It has, however, gained
increasing attention as new EPA V.O.C. regulations have begun to affect
the availability
of traditional oil-based floor finishing products in
many areas of the country.
While the development of "panelization" is
certainly not limited to one brand of finish or to
one particular subfloor design, the problem
has been most closely associated with the use of water-based
sealers and finishes on raw (untreated) maple strip
flooring in areas of the
country that experience distinctly different seasonal
moisture conditions.
MFMA cautions installers and end-users
that the use of some water-based finishes has produced
a sidebonding effect that can result in localized
excessive and irregular separations ("panelization") between maple
flooring strips. We strongly recommend that end-users,
project architects and specifiers consult with their
flooring installer and finish manufacturer
to obtain approved procedures for sealing and finishing
a raw maple strip floor with water-based products.
