2. Install the Corner Pieces First
Start from the bottom and work up. The corner pieces come in 8” and 16” lengths. You should alternate
these in opposite directions on the corner. It is also recommended to lay out the MStone Panels to
make sure that the pattern will meet your needs.
3. Apply Mortar.
Using a mason’s trowel, cover the entire back of all panels completely with a ½” thick, even layer of
mortar.
4. Secure the Stone to the Wall.
The stone needs to be pressed firmly against the scratch coated wall to ensure a sound bond. It is
suggested to keep the stonework free from mortar dropping and mortar smears as much as
possible. Mortar droppings can be removed with a damp cloth.
5. Wetting the Stone and Substrate.
Under certain conditions, the stone and substrate may need to be wetted. If the stone is being
Installed onto a very hot /dry surface or in a hot/dry climate, the stone and wall surface should be wet
to prevent excessive absorption of moisture from the mortar. This can be done by spraying water
on the wall surface and back of stone.
6. Lay the Panels in an Offset Fashion.
I.e. different lengths of panels and staggered joints as this will reduce the appearance
of the vertical joints.
7. For Cold Weather Situations.
Applications should be protected from temperatures below freezing, so the mortar may set up property
as recommended in section “2101.3 Cold-weather construction” of the international Building Code.
8. Cleaning.
After 36 hours, it is suggested to wet the stonework down with water and then apply a mild cleaning
detergent with a soft bristle brush to remove any dirt or mortar smear left from the installation.
Do not use any type of acid.
Completion
1. Stone is a natural product that “breaths”. It does absorb oil, water and other substances that are
in contact with the stone. Sealing is not necessary but may be desirable for attaining deeper and
enhanced colors. Sealants are recommended for interior use where water, oil, or food stuffs maybe in
contact with the stone.
2. The sealer should be tested on small loose “trial” pieces prior to a large area application.
