S T EP T W O: WALL SURFACE PREPARATION EXTERIOR APPLICATIONS Make sure that the application of Modulo Stone products and the structure they are being applied to incorporate good building practices. 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.

STONE IN STALLAT I ON I N ST R UCTI ONS LATH INSTALLATION Where lath is required, it shall be installed in accordance with ASTM C1063. Typically this will require corrosion resistant fasteners every 6" on center vertically, and 16" on center horizontally, fastened to framing. If an alternative lath is used, install it in accordance with the manufacturer’s installation instructions and evaluation report. See the following Material Selection section for more specific lath requirements.

STONE IN STALLAT I ON I N ST R UCTI ONS S T E P FIVE : APPLICATION OF MODULO STONE UNITS PREPARE YOUR WORK AREA Spread Modulo 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.

CUTTING & TRIMMING Stones can be cut and shaped for fit. Use wide-mouth nippers or a hatchet (Fig. 3 & 4). (Refer to page 5, Tools Required section.) 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. Placing a cut edge next to a thick/larger stone will also help conceal the cut. FIG. 3 FIG.

STONE IN STALLAT I ON I N ST R UCTI ONS G E N E R A L I N F O R M AT I O N CLEANING Dirt, etc., may be removed by using a 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. Do not attempt to clean using acid or acid-containing products, power-washing, sandblasting or wire-brush cleaning.

OVERHEAD APPLICATION Overhead, horizontal or sloped applications are not included in our building code evaluation reports or acceptances. These 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.
