stone veneers
installation guide
Congratulations on purchasing one of the finest stone
veneers systems available. Easy to install, barkman stone
veneers were created with the do-it-yourselfer in mind. This
stone veneer system produces an attractive wall with a
natural looking stone texture surface.

construction details
Stone Veneer Over Masonry Surface Cross Section
Brick, Stucco, Masonry or Concrete
Surface must be clean, unpainted
and free from dirt and oil.
Corrosion-Resistant Metal Lathe
Only necessary if surface is unsuitable
for good adhesion. Use 2.5 lb. gauge metal
lathe or 16 gauge 2"x2" corrosion resistant
self-furring stucco mesh.
Scratch Coat
2-parts washed sand to 1-part Portland
cement or “type S” pre-mixed mortar.
Stone Veneer and Grout
Stone Veneer Over Framing Surface Cross Section
Plywood, Drywall or Rigid Foam
Weather Resistant Barrier (2 layers)
Corrosion-Resistant Metal Lathe
Use 2.5 lb. gauge or 16 gauge 2"x2" corrosion
resistant self-furring stucco mesh.
Scratch Coat
2-parts washed sand to 1-part Portland
cement or “type S” pre-mixed mortar.
Stone Veneer and Grout
Stone veneers may be applied from bottom to top or top to
bottom. Working from top down may help to avoid splashing
mortar onto previously applied stone veneers, but working from
bottom up is easier.
Tight-fitted or dry-stacked (mortarless joints) systems should be
installed bottom to top. It is also recommended to add a bonding
agent such as Well Bonding Agent (available at you local lumber
yard) to the mortar mix (see Installation step 3). Tip: Wet the
scratch coat with a brush and water right before applying veneer
or dip piece of veneer in water before applying veneer.

installation
Consult your dealer or contractor to estimate amount of surface
preparation materials, mortar mix and stone veneer pieces required.
1
Prepare Wall
Brick, stucco, masonry or concrete
surfaces require no preparation if
wall is clean, unpainted and free
from oil and dirt. If surface is
unsuitable for good adhesion,
go to step 2, otherwise proceed
to step 3. For plywood, drywall
or rigid foam surfaces, install 2
layers of weather resistant
barrier – overlapping material 2"
horizontally and 6" vertically.
2
Metal Lathe
Install 2.5 lb. gauge metal lathe,
overlapping 1" horizontally and
2" vertically. Wrap lathe around
corners at least 16". Space
galvanized lathe fasteners every
6" vertically (on center) and every
16" horizontally (on center) –
penetrating studs at least 1". Make
sure lathe cups are facing upwards
(lathe should feel rough moving
downward and smooth moving
upward). If using 16 gauge 2"x2"
corrosion resistant self-furring
stucco mesh, make sure self-furring
crimps are against the wall.

Caution: Dry sawing or grinding of concrete products may result in the
release of respirable crystalline quartz. Prolonged exposure to respirable
crystalline quartz may cause delayed (chronic) lung injury (silicosis).
The use of a NIOSH-approved respirator and tight fitting goggles is
recommended when sawing or grinding operations are in progress.

3
Mix Mortar
Mix 2-parts washed sand to 1-part
Portland cement to a firm, moist
consistency or use “type S”
pre-mixed mortar. Mortar that is
too dry will crumble and not
provide a proper bond; too wet
and it will be weak and messy. To
test, place some mortar on trowel
and turn sideways. Mortar should
not slide off – give trowel a shake
and mortar should come off.
4
Scratch Coat
Spread mortar evenly over
metal lathe approximately
3 ⁄ 8" thick.
5
Rake
When scratch coat is “thumbprint
hard” (sticking thumb into mortar
will leave thumbprint, but no
mortar will stick to your thumb)
rake horizontally. Allow scratch
coat to dry for at least 24 hours.
6
Apply Corner Stone Veneers
If your project requires corners,
install these first. Apply mortar
(see step 3) evenly to the entire
back of a stone veneer corner piece
and adhere it to the scratch surface
with even pressure. Corner pieces
have long and short sides which
should be alternated in opposite
directions as you build.
7
Apply Flat Stone Veneers
Once corners are completed, apply
mortar evenly to the entire back of
a flat stone veneer piece and
adhere it to the scratch surface with
even pressure. Place stone veneer
pieces close together creating
uniform joints between them.
Average joint should not exceed
1⁄ 2" to obtain natural look. Cut
pieces as required. Fit small pieces
into any remaining gaps.
8
Add Additional Mortar
All edges or voids around the stone
must be filled with mortar. Use a
grout bag to fill in voids. Care
should be taken to avoid smearing
mortar on the surface of the stone.
9
Smooth Out Mortar
Once mortar joints have become
“thumbprint hard” (sticking thumb
into mortar will leave thumbprint,
but no mortar will stick to your
thumb), smooth out with jointing
tool to the desired depth.
10
Brush Off Loose Mortar
Once mortar has set, use a dry
brush to remove loose mortar and
to clean the stone veneer surface
(never use a wet brush or acid
based products).
