What is Grout?
According to the
Merriam-Webster
dictionary:
A thin mortar used for
filling spaces (as the
joints in masonry or
ceramic tile); also: any
of various other
materials (as a mixture
of cement and water or
chemicals that solidify)
used for a similar
purpose. A building
material (as a mixture
of cement, lime, or
gypsum plaster with sand
and water) that hardens
and is used in masonry
or ceramic tile.
Research shows
Sanded grout is a porous
and brittle material
used between ceramic
tiles for esthetics,
not strength. Ceramic
tiles are actually held
in place by "Thin-Set,"
a masonry based
adhesive, used under the
tile to form a bond with
the surface the tile is
to be affixed. Sanded
grout is applied hours
or days after the
ceramic tiles are
solidly bonded to the
surface below, which
causes a cold joint
between the newly
applied grout and the
previously hardened
thin-set. High-pressure
surface cleaning will
actually loosen and
remove the sand in the
grout through
"Hydrostatic Vibration
and Erosion" thus
allowing the loosened
sand to be removed by
the suction of the
extraction tool. If you
find sand in your waste
tank, it is most likely
from your customers
grout! Therefore,
repeated high-pressure
(500+ p.s.i.) cleaning
and/or rinsing can do
nothing but loosen and
eventually remove the
grout.
REMEMBER: Square blocks
of aluminum are carved
into round wheels for
cars and motorcycles by
jets of water!
Therefore it is our
considered opinion that
high pressure cleaning
tools can be harmful to
grout if used on a
regular basis. It is
also not necessary to
use such aggressive
cleaning methods after
the grout is properly
prepped and Color
Sealed. Grout Perfect
Color Seal creates an
extremely easy-to-clean
surface when applied
properly, making a happy
customer for years!
