FURAN RESIN GROUT
Furan resin grout is a grout system consisting of furan resin
and hardener portions. Furan grout is used in industrial and
commercial installations requiring chemical resistance.
Furan resin grouts are a highly specialized grout, a thermosetting
polymer designed to withstand continuous exposure to
temperatures up to 350° Fahrenheit. As a grout it is primarily
used in applications such as dairies, that require resistance to
routine exposure from organic acids (contained in milk products)
and elevated temperatures. Furan is a reactive polymer-like
epoxy, though it requires special installation techniques and
should not be attempted by a novice. It can not be cleaned
from the surface of the tile with water alone during the installation
process, and generally requires pre-sealing of the surface of the
tile before installation. Furan grouts meet the requirements of
ANSI A118.5.
While epoxy grout does not meet the definition of a furan
grout, many epoxy grouts claim to meet the performance char-
acteristics of a furan grout. These epoxy grouts do have higher
resistance to extreme temperatures and will hold up longer when
exposed to most corrosive chemicals, but they are not based on
furan resins. They are easier to install than true furan resin grouts,
but generally not as easy as the more common 100% epoxy
grouts meeting the requirements of ANSI A118.3.
PRE-MIXED POLYMER RESIN GROUT
Pre-mixed polymer resin grout is a one-part liquid, ready-to-use
grout that requires no mixing with water.
These recently developed, easy to use grouts are generally a
mixture of acrylic and/or urethane polymer, fine fillers and water.
They are pre-blended and can be applied to the joints between
installed tiles straight from the container; no or little mixing is
required. While these are acknowledged by TCNA and the tile
industry as an alternative to traditional grout, they do not have
ANSI or other specifications to date. Since there are no standards,
there are wide variations in the properties of these premixed
grouts from the various suppliers. They can dry slower than
traditional Portland cement and epoxy grouts.
DIY installers are attracted to the convenience of opening the
container and being able to begin spreading with no mixing
required. Custom Building Products has developed one of the
best grouts in this category with the SimpleGrout
®
brand.
