• Penetrating/impregnating
stone sealers are a no-
sheen, natural-look sealer
that can be water-based or
solvent-based.
• A premium, natural-look,
penetrating/impregnating
sealer is the normal choice
for natural stone when a
natural color of the stone
is desired. A stone-
enhancer sealer is often
used when a darker,
enriched, or highlighted
character is desired.
• Make sure the brand
you have chosen is
formulated to provide
maximum stain protection
for stone products.
• Stone products should
be tested periodically to
ensure that the sealer is
working eectively.

• Suitable for use in wet, but not fully submersed
areas, such as shower walls.
• It is recommended to use a white thin-set mortar
with a flexible acrylic additive or a white polymer
fortified thin-set mortar.
•
Apply this mixture with the manufacturer’s
recommendations of a notch trowel (typically 3/16 in.
x 3/16 in. V-notch).
• Knock down the trowel ridges with the flat edge of the
trowel to produce and evenly layer the thin-set mortar.
•
Spread only enough thin-set to install a few sheets
at a time. Fully butter the back of each sheet with
the flat edge of the trowel in order to avoid the notch
marks in the thin-set from showing through the glass.
•
Carefully press into the thin-set, leaving even spaces
in between tiles. A grout float can be used to tap
the tiles into place. Allow for movement joints where
the tiles abut restraining surfaces and around the
perimeter of the installation.
NOTE: We recommend allowing a
1/8 in. joint between tiles.
• If stone, seal prior to grouting.
