Finishing
Estimating The Stone Quantity
Calculate the amount of flat surface stone by multiplying the height times the width of the
surface area to be covered. Subtract the area taken up by windows and doors. Square
footage of stone per box is printed on box end. For corner quantities, measure the linear
feet of corners.
Recommended Tools
Interior and Exterior Application: Trowel, square notch trowel, carbide file, chalk
line, level, gloves, safety glasses, and scrub sponge.
Exterior Application: Mixing container, hoe.
Grouting (Springbrook, River Stone, and Portina only): Add grout bag, pointer, and hand
whisk broom.
Cutting the Stone Veneer: A variety of tools can be used to
cut the stone veneer—they include: carbide grit rod saw, grinder
with carbide bit, or wet saw with carbide blade.

Step 1. Install Felt Paper
over wood sheathing.
Step 2. Install Lath over Felt
Paper, cups of Lath facing up.
Step 3. Apply Mortar over
Lath with notched trowel.
Step 4. Wet the veneer stone
and scratch coat surface.
Flashing
Flashing shall be installed per building code.
Install galvanized or aluminum flashing at all
dissimilar materials plus Ice and Water
Barrier strips at all terminations and
window and door openings.
Installing over Concrete,
Concrete Block, or Brick
Masonry must be unpainted or unfinished.
Veneer can be installed directly to these
surfaces. Wet back of Stone and masonry
surface to dampen as required. Install with
Stone Mortar Mix.
Installing over Wood Sheathing
Water Barrier: Apply a water barrier of; 2
layers of 30 lb. Asphalt Impregnated Felt
Paper (Tar Paper) over wood sheathing. Lap
all seams 4". Use Ice and Water Shield at all
door and window openings to interface
with the galvanized or aluminum flashing.
Provide termination drip edge if required. If
required by the Building Code, over Tar
Paper provide breather fabric with integral
filter fabric and weep openings
(see Step 1).
Wire Lath (option 1): Apply 2.5 lb. per
square foot Galvanized Wire Lath over the
vapor barrier or breather fabric
(see Step 2). Make sure the mortar
covers all of the lath and has room to key
completely into the lath. Lap seams 1" at
bottom and sides. Wrap corners 16"
minimum. Secure with fasteners 16" on
center horizontally and 6" on center
vertically. To Wood Studs, use Galvanized
nails, staples or screws that penetrate the
stud 1". To Metal Studs, use Corrosion
resistant, self-tapping screws with a 0.48"
head that provides 0.37" penetration
beyond the inside metal surface. Refer to
the Metal Lath Manufacture’s recommenda-
tions for their specific instructions for
applications of their product.
Cement Board (option 2): In place of
wire lath, attach Cement Board over Felt
Paper and apply Stone directly to the
Cement Board using Stone Mortar.
Dampen surfaces to be mortared before
applying. If required by code, provide
breather fabric and weep openings
between Cement Board and Felt Paper.
Mortar Preparation
Use Stone Mortar Mix. Mix with water.
Apply a 1/2" scratch coat to the entire
galvanized lath surface. Use the square
notch trowel over the mortar to provide a
raked surface
(see Step 3). Let dry.
Check with mortar manufacturer to ensure
the product meets or exceeds 50-psi shear
bond strength.
Veneer Stone Preparation
Wet the veneer stone and the scratch coat
surface
(see Step 4).
Installation
Use level and chalk line to mark placement
of first course. Start with the corners. Keep
stone 4" minimum from grade. Generously
butter the piece with stone mortar and
press firmly into place
(see Step 5). It is
best, when installing, to work from the top
to bottom to prevent mortar from falling
on the stones below. If grouting is required
allow a minimum joint of 3/4". After
corners are up install veneer stone flat
pieces by buttering the backside and press
firmly into place. If needed, layout stones on
the ground to get a sense of the pattern
you will use. Work from the top to bottom
to prevent mortar from falling on the
stones below. Cut stone as needed.
Over Most Surfaces
Generously butter Type-One Mastic
Adhesive to the back of the stone and
press firmly against the wall.
NOTE: Some surfaces, such as a high gloss
paint, may need to be sanded. Unpainted
gypsum wall board surfaces should be
sealed with a paint primer.
Grouting
Springbrook, River Stone, and
Portina Only: Use Stone Mortar Mix or
Masonry Joint Grout for grouting. Use
grout bag and apply grout between stones
(see Step 1). Allow grout to set until
mortar is firm, NOT DRY. Use a pointer or
striker to work grout into the joints
(see Step 2). Brush away any unwanted
mortar on stone face with the hand whisk
brush as you work
(see Step 2).
Roma, Niagra.
Mortar Adhesive, stacked tight. NO grouting.
Springbrook, River Stone, Portina.
Mortar Adhesive and 1/4" joints for grouting.
Cleaning the Stone
It is best, when installing, to be careful not
to get mastic or mortar on the stones. If
you need to clean, use warm water and a
scrub sponge. Do not scrub the entire
stone, just the affected area. DO NOT use
any types of acids on the stones.
Sealing the Stone
It is recommended that you seal the stone
with a deep penetrating sealer.

Interior Installation
For Better Adhesion
Apply Type-One Mastic to the wall surface
with the notched trowel. Let dry then
follow the steps above.
Installing the Stone
Use level and chalk line to mark placement
of first course. Start with the corners.
Generously butter the piece and press
firmly into place (see Step 1-2). For
Springbrook and River Stone it is best,
when installing, to work from the top to
bottom to prevent mortar from falling on
the stones below during grouting. When
grouting is required allow a minimum joint
of 3/4". After corners are up install veneer
stone flat pieces by buttering the backside
and press firmly into place. If needed, layout
stones on the ground to get a sense of the
pattern you will use. Cut stone as needed.

Grouting Notes *
Grouting required for Springbrook,
River Stone, and Portina.
NO grouting required for Roma and
Niagra. These are “stacked stone”
styles with closely fitted seams.
