•   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.
