2. minimum of 16” around all outside and inside corners. Apply ½” scratch coat and allow to dry 48
hours.
3. Sheathed Surfaces and Rigid Insulation Board: Install 2 layers of weather resistant barrier with
lap joints 6” shingle fashion. Apply code approved metal lath, attach with galvanized nails or staples which penetrate a minimum of 1”. Apply 6” on center vertically and 16” on center horizontally.
Wrap weather resistant barrier and [metal] [plastic] lath a minimum of 16” around all outside and
inside corners. Apply ½” scratch coat and allow to dry 48 hours.
4. Over Metal Panel: Surface preparation is the same as for sheathed surfaces except the metal
lath must be attached using self-tapping screws with a 3/8” head that provides 3/8” minimum
penetration beyond the inside metal surface.
5. Concrete and Masonry Surfaces - New, Clean and Untreated: No preparation needed. Examine newly poured concrete closely to ensure that its finished surface contains no releasing agents
(form oil). If it does contain form oil, etch surface with muriatic acid, rinse thoroughly and/or score
with a wire brush, or use high pressure water or sandblasting to remove. For added insurance to
minimize cracking or bond failure, lath and scratch coat can be applied.
6. Existing Concrete and Masonry Surfaces: If required, remove paint, coatings, sealers, and dirt
as recommended above.
3.04 MANUFACTURED STONE VENEER INSTALLATION
A. Laying out the Stones: Before you begin, lay out a quantity of stone (25s.f. minimum) near the
work area to give you a selection to choose from. When installing stone, be sure to achieve a
balanced pattern of shapes, sizes, colors and thicknesses by selecting and mixing the various
stones. Always select and mix stone from different boxes throughout installation.
B. Starting: Landmark Stone is applied from the top down. This helps to keep the stone clean during installation. Install the corners first for easiest fitting
C. Setting Units: Using a mason’s trowel, apply a ½” thick even layer of mortar to the entire back of
the stone. 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.
D. Cutting: Perform necessary cutting with proper tools to provide uniform edges; take care to prevent breaking unit corners or edges.
B. Finish Color/Textures/Patterns: Avita, Stacked Stone Blend Ashford mixed colors. See Hamilton Parker Co. for product info. And pricing.

3.06 CLEANING
SECTION 04 73 00
MANUFACTURERED MASONRY
A. Cleaning: Use a strong solution of granulated soap or detergent and water with a plastic bristle
brush. Do not use a wire brush as it will cause damage to the surface. Rinse immediately with
fresh water. Do not attempt to clean using acid or acid based products. Do not clean with highpressure power washer.
B. Salt and De-icing Chemicals: Do not use de-icing chemicals on areas immediately adjacent to a
Landmark Stone Products application.
C. Scuffing: Remove scuff marks by cleaning as specified herein.
D. Efflorescence: To remove efflorescence, allow stone to dry thoroughly, then scrub vigorously with
a stiff brush and clean water. Rinse thoroughly. Do not use a wire brush. For difficult efflorescence problems, scrub thoroughly with a solution of 1 part white household vinegar to 5 parts
water. Rinse thoroughly.
3.07 PROTECTION
A. Protection: Protect installed product and finish surfaces from damage during construction.
