Jointless or Dry-Stacked Installation

(Read Prior to installation)

The MStone system is a jointless / dry-stacked installation where panels and

corners fit tightly together without grouted joints.

Materials

Weather resistant Barrier: (where required)

All exterior surfaces require a water/weather resistant barrier before installing

MSTONE Panels. This barrier must meet local building codes, UBC standard Code

141 regarding waterproof building paper or asphalt saturated building felt.

Rigid noncorrosive flashing is required for exterior wall use.

Lath or Wire Mesh: (Where required)

Install a 2.5 lbs. diamond mesh expanded metal lath or an 18 gauge woven

wire mesh: Exterior applications will require a galvanized metal lath, however

a non-galvanized black metal lath may be used for interior applications.

Overlap lath sides by not less than 3/8 in. and lath ends by not less than 1

in. Attach the lath using galvanized nails or staples 6 in. on center and 16 in.

Horizontally, penetrating studs to a minimum of 1 in. Continuously wrap metal

lath a minimum of 16 in. around all outside and inside corners.

Scratch coat:

Apply a ½ in. thick scratch coat of mortar over the metal lath. Use a toothed

scraper, notched trowel or small piece of lath to lightly rake horizontal grooves

in the scratch coat, and allow the mortar to set. Mortar should be mixed to

a firm but workable consistency. MStone systems recommends type n or

s mortar combined with a bonding agent** (see architecture specification

document for additional information). It is recommended that the scratch coat

dry for at least 24 hours. Certain weather conditions may require that the

scratch coat is moistened prior to the installation of the MSTONE panels.

** Integral bonding agent meeting ASTM C 9322 or ASTM C 1059 type ii. Refer to

manufacturers’ instructions for mix ratio.

Installation Guide | Wall Panels Estimating Stone Quantities Needed Estimating Work Sheet Panels (flats) and Corners can be used for all installations. Panels are applied to the flat wall surface and are ordered per piece. Each piece is one square foot (6” x 24”). Corners are applied to outside or inside corners and are ordered in square feet. Each corner comes in two pieces, 6” x 8 “ and 6” x 16 “ with the twocombined equaling one square foot. Doors/ Windows Project Sq. Footage Openings Sq.

Installation Guide | Panels 2. Install the Corner Pieces First Start from the bottom and work up. The corner pieces come in 8” and 16” lengths. You should alternate these in opposite directions on the corner. It is also recommended to lay out the MStone Panels to make sure that the pattern will meet your needs. 3. Apply Mortar. Using a mason’s trowel, cover the entire back of all panels completely with a ½” thick, even layer of mortar. 4. Secure the Stone to the Wall.

Installation Guide | Panels Exterior Framed Back Up Wall (Includes wood stud and steel stud framing Fig.1) An exterior sheathing is required to provide a base for the application surface. This sheathing must meet local building codes for use as an acceptable exterior product which can include plywood, green treated plywood, and rigid composite board, and flush metal siding. Cover sheathing with weather resistant vapor barrier. Figure 1 1. Sheathing 2. Weather Resistive Barrier 3. Galvanized Metal Lath 4.

Installation Guide | Panels New Concrete Masonry Wall (Includes new concrete block or newly poured concrete wall Fig.2) No special preparation is required for a concrete block wall. When working with a poured concrete wall, it is important to take extra time to examine the entire surface as it may have areas of form release agents on the concrete surface. To remove this oil, apply and etch areas with muriatic acid, rinse thoroughly and/or score the area with a wire brush.

Installation Guide | Panels Rigid insulation (See Fig.3) Install the expanded metal lath as specified by the manufacturer’s insulated Forms. Concrete fasteners that secure the expanded metal lath to the wall need to be long enough to penetrate clear through the insulation and secure into the cured poured concrete wall. Apply 1⁄2” thick scratch coat. Figure 3 1. Rigid Insulation Board 2. Weather Resistive Barrier 3. Galvanized Metal Lath 4. Mortar 5.
