3. Product Description
Cultured Stoneª products are intended for interior or exterior nonstructural use as a lightweight veneer facing on masonry, metal
framed, or wood framed construction for
architectural aesthetics. Products are created
by master craftsmen who select the best textures, sizes and shapes from natural stones.
These products are suitable for use on residential and commercial projects of many
types. Cultured Stone products are produced
in preselected sizes and shapes. No additional foundation or structural support is required.
Installation is quick and easy, and costs far less
than a full thickness natural stone wall.
Cultured Stone products are cast in molds
using a unique process that replicates existing
colors and textures with meticulous detail.
Each color and texture has its own blend of
ingredients, including Portland cement, lightweight aggregates and iron oxide pigments,
producing the look and feel of natural stone.

• Brick veneer - 5 types
• Hearthstones - 12 types
• Quoins - 1 type
• Capstones - 16 types
• Watertable/Sill - 4 types
Random sizes, shapes and textures of finished
product duplicate natural stones as mold masters. Stone diameter varies from 2" - 30"
(51 - 762 mm). The average thickness of
Cultured Stone wall veneers is 1 3/4" (45 mm).
Thickness may vary from 1" - 3 1/2" (25.4 - 89 mm)
depending on the texture.
Shipping weight is approximately 8 -12 psf (39
- 59 kg/m2).

Cultured Stone wall veneers and hearth
stones are made from noncombustible materials. They are listed by Underwriters
Laboratories, Inc. (UL File #MH11019), for use as
floor protectors and wall shields with stoves
and on fireplace hearths. Mortar joints must
not exceed 1/2" (12.7 mm) in width and the
mortar must be even with the top of the
hearth surface.

ing as mortar will not set up properly under
such conditions. Do not use antifreeze compounds to lower the freezing point of mortar.
Handle and store product according to
Cultured Stone recommendations. Spread out
Cultured Stone products at the jobsite so
there is a good variety of sizes, shapes, and
colors to choose from. Plan some variety and
contrast in the overall design. Use small stones
next to large ones, heavy-textured pieces
next to smooth, and thick stones next to thinner ones. Mixing Cultured Stone products from
different boxes during application will allow a
desirable balance of individual stones on the
finished project. Tinting mortar complements
the color of the stone being installed. For
example, use tan mortar with earth tone
stones. This will greatly enhance the appearance of the finished installation. Regular mortars can be tinted to complement Cultured
Stone products using iron oxide pigments.
Exterior Applications
Make sure that the application of Cultured
Stone products and the structure to which they
are being applied incorporate good building
practices. On exterior applications, the incorrect installation or absence of flashing, cant
strips, gutters and downspouts may result in
diversion of water runoff onto finished surface
areas. Masonry and other building products
subjected to these conditions may develop
staining and, when combined with severe
freeze/thaw conditions, may eventually cause
surface damage. The application of Cultured
Stone products under these conditions is not
Determine the amount of Cultured Stone
product needed by measuring the area to be
covered. Measure the length times the height
to arrive at the square footage of flat stone
needed. Subtract square footage for window
and door openings. Measure the linear feet of
outside corners to determine the amount of
corner pieces needed. One linear foot of corner pieces covers approximately 3/4 of a
square foot of flat area. Subtract the flat area
covered by the linear feet of corner pieces
from the square footage of flat stone
required. Obtain some extra stone to allow for
cutting and trimming.
If stone is being applied in hot or dry weather,
the back of each piece should be moistened
with a fine spray of water or a wet brush to
adequately prevent excessive absorption of
moisture from the mortar. If being installed
over concrete, masonry or scratch coat substrate, the substrate surface area should also
be dampened before applying mortar.
Applications should be protected from freez-

Applying Mortar to Prepared Surface Area
Using a trowel, apply mortar 1/2" - 3/4"
(12.7 - 19.1 mm) thick to prepared surface
area. Do not spread more than a workable
area of 5 - 10 ft2 (0.47 - 0.93 m2) so that mortar
will not set up before stone is applied.
Starting Point
Apply mortar and stone working from the bottom up, or most stones can be applied from
the top down. Working from the top down
may help avoid splashing previously applied
stone with dripping mortar. Ledgestone types
should be installed from the bottom up.
Joint Width
In order to obtain the most natural look, joints
should be as narrow as possible; average
joints should not exceed 1/2" (12.7 mm) in
width. An attractive look can also be
achieved by fitting stones tightly together if
Setting the Stones
Press each stone into the mortar setting bed
firmly enough to squeeze some mortar out
around the stone’s edges. Apply pressure to the
stone to ensure a good bond. Ensure complete
coverage between the mortar bed and back
surface of the stone. Mortar may also be
applied to the entire back of the stone.
Incorporate good building practices. Building
code requirements vary from area to area, so
check with authorities for local requirements.
Carefully read all installation instructions before
proceeding with Cultured Stone products
application. Observe applicable jobsite safety
