inspection
No two pieces of natural stone are
exactly alike. Tiles must be
inspected prior to installation to
ensure that no blending is required.
No claims will be accepted by
Island Stone after installation. Use
of product implies acceptance.
substrate prepation
In order to achieve good adhesive
bond, be sure to identify any
surface contaminants that may be
present and remove. Island Stone
Stacked Pebble is approximately
7lbs./sq.ft. installed, and in some
instances may require structural
angle support. An engineers
opinion may be needed for weight
bearing walls.
waterproofing
As required for interior or exterior
a p p l i c a t i o n . I t i s s t r o n g l y
recommended that membrane
systems are used in all wet areas.
adhesive
Use a thin-set tile adhesive with no
vertical slump.
grout
Island stone recommends sanded
grout with a grout additive for
flexibility and improved adhesion.
• Natural grey color gives good
results, but any matching color is
fine to use.
• Approximately 1.25lbs of sanded
grout per sq.ft.
installation notes:
tools
• Soft grouting sponge and other
typical grouting tools.
• Notched trowels.
• Two brushes: a stiff wisk-brush &
a soft paint brush.
installing the tile
• Tiles should be brick stacked. •
Ensure pebble lines run even and
parallel by marking the substrate
with a guideline.
• Press tile firmly into tile-set by
hand, then tap with a rubber
backed grouting tool to ensure full
contact with thin-set adhesive.
• The pebbles should be vertical to
the substrate.
pre-grout sealing•
To en su re t he b es t pos si bl e
installation, an appropriate
penetrating sealer should be used
as a grout-release prior to grouting.
grouting
• Allow a one day drying period
prior to grouting.
• Apply a fairly “stiff” sanded grout
with a rubber backed grouting tool
• Allow grout to dry to a granulated
stage.
• Sponge surface grout away.
• Brush grout out to desired depth
with a “firm” bristled wisk-brush.
This removes much more grout
than just normal sponging.
• At least half the depth of each
pebble should be visible before
going to the next step.
• Sponge deeply again.
• Final brushing with a softer “wet
paint brush” to smooth the
recessed grout deep between the
pebbles.
• Final sponging of pebble tops.
cleaning & sealing
• After a days drying, remove any
remaining cement film with a
chemical grout film remover.
• A quality penetrating and/or
stone- enhancing sealer should be
applied for a long lasting finish to
the stone and grout.
