ESTIMATING THE STONE REQUIRED
Determine the amount of Cultured Stone® products needed by
measuring the area to be covered. Measure the length times the
height to arrive at the gross square footage of flat stone needed.
Subtract square footage for window, door and other 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. You may wish
to obtain some extra stone to allow for cutting and trimming.
In addition, be sure to verify whether the texture chosen is
sold based on coverage with a 1⁄2" mortar joint or tight-fitted.
Most texture coverages are listed for a 1⁄2" joint, the exceptions
being Drystack Ledgestone, European Castle Stone, Pro-Fit®
Ledgestone and Pro-Fit® Alpine Ledgestone.

A. Starting Point
Apply mortar and stone working from the bottom up, or most
stones can also 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.
Figure 5
NOTE: Weather Conditions
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 temperatures below 40°F
as mortar will not set up properly under such conditions. Do not
use antifreeze compounds to lower the freezing point of mortar.
See International Building Code Section 2104.3 for cold weather
construction requirements.
A. Mixing Mortar/Grout
Using Premixed Type N mortar or components from Table 2,
mix to a firm, moist consistency. Mortar that is too dry and
crumbly will not provide proper bond. Mortar that is too wet
will be weak and messy.
Table 2 – Proportions for Mortar
Parts By Volume

Watertables/sills provide a transition piece between a stone
wainscot and other exterior finishes and for water runoff. They
can also be used as a windowsill. Install using galvanized metal
support brackets (Simpson Strong Tie A-21 or other galvanized
right angle bracket with holding capacity minimum 5 lbs./LF)
fastened with galvanized nails or screws penetrating studs 1" at
a minimum of 16" on center. Use construction adhesive to bond
stone at bracket locations. Caulk and flash as required at Watertable/
Sill locations using an approved corrosion-resistive flashing that
extends to the surface of exterior wall finish and is installed to
prevent water from re-entering the exterior wall envelope.

Spread Cultured Stone® wall veneer out at the job site so you have
a good variety of sizes, shapes and colors to choose from. Plan
for some variety and contrast in the overall design. Use small
stones next to large ones, heavy-textured pieces next to smooth,
thick stones next to thinner ones. Mixing Cultured Stone® wall
veneer from different boxes during application will allow you to
achieve a desirable balance of stones on your finished project.

or a hatchet (Fig. 12 and 13). (Refer to page 9–Tools Required.)
Some broken stones may be found in the box. These also may
be used in filling gaps between large stones. For best finished
appearance, coat cut or broken edges with mortar. If possible,
position cut edges up when they are above eye level, down
when below eye level. SAFETY GLASSES AND A DUST
MASK SHOULD ALWAYS BE WORN WHEN CUTTING

B. Joint Width
In order to obtain the most natural look, joints should be as
narrow as possible. The average should not exceed 1⁄ 2" in
width. An attractive look can also be achieved by fitting stones
tightly together if desired. If using tight fit/drystack method,
it is important to make sure scratch coat/backing has been
covered completely by the setting bed of mortar. This will
conceal the scratch coat/backing and prevent pockets from
forming behind stones that could trap water.
* Failure to properly caulk and/or flash as described in these installation directions may
result in water damage to the structure.
INSTALLING STONE AT GROUND LEVEL
Keep the finished edge of the Cultured Stone® product a minimum
of 4" above grade if earth or 2" above pavement. Use a 2" x 4"
leveling strip (straightedge) or weep screed (Fig. 5). This will:
Mortar
Mortar
• Provide drainage as required by applicable building code.
• Avoid possible staining of the stone by soils containing alkali
or other minerals.
Figure 8
Ledgestone Types
When applying ledgestone types, keep joints as small as possible
to maintain a natural look, and install from the bottom up. Strike
joints deeply, being careful not to expose the back edge of stones
or scratch coat/backing.
Mortar applied to the
entire back of the stone.
Care must be taken to avoid smearing mortar on surface of stone.
Accidental smears should be removed using a whisk broom only after
mortar has become crumbly.
See page 6 for additional instructions regarding Pro-Fit® Ledgestone,
Pro-Fit® Alpine Ledgestone and European Castle Stone.
D. Install Corner Pieces First
If your application requires corner pieces, apply these first. Notice
that the corner pieces have a long and a short leg. Alternate
these in opposite directions (Fig. 9).
GROUTING AND FINISHING JOINTS
A. Grouting Joints
If additional mortar is required, use a grout
bag to fill in joints (Fig. 14). Care must be
taken to avoid smearing mortar on surface of stone. Accidental smears should be
removed only after mortar has become
crumbly using a whisk broom or dry bristle
brush. Never use a wet brush or wire brush.

E. Install Flat Pieces
After the corner pieces are in place, flat pieces are applied
working toward the wall center (Fig. 10).
F. Keep Your Mortar Joints Consistent
B. Finishing Joints
When the mortar joints have become
firm or “thumb-print” dry (setting time
will vary depending on wall surface and
climatic conditions), they should be
pointed up with a wood stick or metal
jointing tool. Rake out excess mortar,
compact and seal edges around stones
(Fig. 15). Careful attention to proper
and even jointing will result in a
professional looking finish.
Figure 10
Apply flat pieces.
Figure 15
Finishing the job.
C. Cleaning Finished Job
At the end of the work day, or when mortar is sufficiently set
up, the finished job should be broomed or brushed to remove
loose mortar and to clean the face of the stone. A wet brush
should never be used to treat the mortar joints as this
will cause staining that will be difficult, or impossible, to remove.
Do not use acid or acid-based products.
Figure 11

plasterer’s trowel.
Trim with
a hatchet.
River Rock and Stream Stone
When applying River Rock or Stream Stone, plan the placement
of stones to minimize trimming and cutting to maintain the natural
look of the rounded shapes.
Place the individual stones close together, creating uniform joints
between them. Cut and trim as required to achieve consistent
width in the mortar joints. Then trim and fit small pieces into any
remaining voids (Fig. 11).

NOTES:
Level and Plumb Joint Lines
When applying Cobblefield® manufactured stone veneer, European
Castle Stone, Limestone or ledgestone, endeavor to maintain level
and plumb joint lines. Also, long rectangular pieces will look most
natural if applied horizontally.
C. 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 (Fig. 8). When stone is installed correctly, scratch
coat/backing will not be visible.
C. Applying Mortar to Prepared Surface Area
Using a plasterer’s or mason’s trowel (Fig. 6 and 7), apply mortar
1⁄ 2" to 3⁄ 4" thick to prepared surface area. Do not spread more
than a workable area (5 to 10 sq. ft.) so that mortar will not
“set up” before stone is applied.

Salt and De-Icing Chemicals
Because all concrete and masonry are vulnerable to damage by
salt, Cultured Stone® products are not warranted against damage
incurred from salt or other chemicals used to remove snow or
ice. Do not use de-icing chemicals on areas immediately adjacent
to a Cultured Stone® manufactured stone veneer application.
Tuscan Lintel Installation Instructions
Method One
On installations where the top of the opening provides no support
for the bottom edge of the Tuscan Lintel: Install metal support
brackets as per Cultured Stone® Installation Instructions for
Watertables/Sills. Then install Lintel stones in a full setting bed of
mortar in accordance with Cultured Stone® Installation Instructions.
Scuffing
Scuffing occurs on all natural stone. Occasionally some scuffing
will occur on the surface of Cultured Stone® products. This can
enhance the natural appearance of your Cultured Stone®
manufactured stone veneer installation. Some scuff marks can
be removed by cleaning as described above.
Method Two
On installations where the bottom edge of the Tuscan Lintel will
be supported by a window or door frame’s molding or profile:
Install lintel stones in a full setting bed of mortar in accordance
with Cultured Stone® Installation Instructions.
Make sure you do not cause deflection to window with weight
of Lintel. If there is any question, use method one.
Efflorescence
Efflorescence is a water-soluble salt that is deposited on the
surface of stucco, concrete, brick and other masonry products
by the evaporation of water that has penetrated the wall.
On rare occasions efflorescence will occur on Cultured Stone®
products. To remove efflorescence, allow the stone to dry
thoroughly, then scrub vigorously with a stiff bristle brush and
clean water. Rinse thoroughly—do not use a wire brush. For
more difficult efflorescence problems, scrub thoroughly with
a solution of 1 part white household vinegar to 5 parts water.
Rinse thoroughly. For unusually difficult cleaning problems, contact
your local Cultured Stone® dealer.
Terra Craft® Patio Paver Installation Instructions
Base Preparation
• Using a flat shovel, spade or sod cutter, remove sod and
enough soil to accommodate the materials you are about to
add. Base preparation materials will vary depending on soil
type and local building codes. The cleared area should extend
approximately 6" beyond final perimeter.
• Using a hand or power tamper, compact the area to be paved.
• Add approximately 2" of small gravel or screenings. Compact again.
• Edge stones will require some type of restraint to prevent
them from shifting, and that material should be installed next.
Products commonly used for this purpose are: wood, plastic
or metal edging, concrete or mortar.
Sealers
Sealers are not necessary on Cultured Stone® products. However,
some customers use sealers to help prevent staining in applications
prone to smoke, soot, dirt or water splashing. If you choose to
use a sealer, make sure it is a silane-based, breathable sealer. Take
note that sealers may darken the color of the stone. A sealer
may also slow the natural movement of moisture out of the stone
and increase the possibility of efflorescence and/or spalling. For
information regarding actual performance or application of
sealers, contact the manufacturer of the sealer directly.
Sand Bedding Preparation
• Spread one inch of sand over your base.
• Using a piece of wood, level the sand by dragging it over the
top to “screed.” This works best if you set up screed guides
to hold the wood at the proper height as you slide it over the
sand. Remove the screed guides when the sand is level and fill
in any holes left by them.
• Don’t walk on the level sand. Your finished job will only be as
good as the sand bedding preparation.
Swimming Pools
Cultured Stone® products should not be used below water level, as
in swimming pool liners. Chlorine and other chemicals may discolor
the Cultured Stone® products and other masonry materials.
Installing the Pavers
• Using a string as your guide, begin installing the pavers in
the pattern you desire.
INCORPORATE GOOD BUILDING PRACTICES
Building Code Requirements
Building code requirements vary from area to area. Check with
local authorities for building code requirements in your area.
Carefully read all Installation Instructions before proceeding with
your Cultured Stone® manufactured stone veneer application.
• Set the pavers hand tight, checking frequently to assure
you are running straight and have good spacing.
• When all pavers are in place, sweep fine joint-filling sand
over the paved area, making sure to fill all gaps.
Exterior Applications
Make sure that the application of Cultured Stone® products
and the structure they are being applied to incorporate good
building practices. Rigid, corrosion-resistant flashing shall be
installed at all wall penetrations. Flashing type and locations shall
be in accordance with the requirements of the applicable building code. On exterior applications, the incorrect installation or
absence of flashing, cant strips, gutters and downspouts may
result in diversion of water run-off 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 damage.
The application of Cultured Stone® products under these conditions is not recommended.
• Some customers use a vibratory plate compactor to
set the stones.
• Remove excess sand.
• Backfill with topsoil and sod or seed as necessary.
GENERAL INFORMATION
Cleaning
Dirt, etc., may be removed by using a strong solution of
granulated soap or detergent and water with a bristle brush.
Do not use a wire brush as it will cause damage to the
surface. Rinse immediately with fresh water. For help with serious
cleaning problems, contact your local dealer. Do not attempt
to clean using acid or acid-containing products, powerwashing, sandblasting or wire-brush cleaning.
applications often require special approval/inspections by local
building code inspectors. Contact your architect or engineer for
assistance designing these installations.
Installation Over Thick Foam
Installation over foam board thicker than 1⁄2" may require special
fasteners. Consult your architect or engineer for assistance
designing a thick foam installation.
Capping Off the Exposed Top of Exterior Walls
To achieve a finished architectural look on horizontal or sloping
top areas of exterior walls, piers, retaining walls or other surfaces,
Cultured Stone® Capstones or a poured-in-place concrete cap
must be used to provide adequate run-off protection to the
wall areas. Caps should extend approximately 1"– 2" beyond the
finished stone surface. Cultured Stone® corner pieces or
flat pieces must not be used to cap walls.
Retaining Walls
All retaining walls must be waterproofed at the fill side. Wall
construction should incorporate proper use of granular backfill
and provisions for good drainage. A continuous longitudinal drain
along the back of the wall set in drain rock is recommended.
Chimney Cap
All chimney chases must be capped with a one-piece cap
that extends 1"–2" beyond the finished stone surface to
prevent water from entering the wall system. Chimney or
chase construction should incorporate proper flashing.
