Building code requirements vary from area to area. Check with local authorities for building code requirements in your area. Carefully read all Installation Instructions before proceeding with your Cultured Stone® products application. Observe safety precautions. Cultured Stone® products are covered by a 50-Year Limited Warranty when installed in accordance with the manufacturer’s Installation Instructions. See warranty on page 10. 2. For additional recommendations regarding flashing, refer to the following trade associations, standards, organizations and resources: a. ASTM E 2112 b. Asphalt Roofing Manufacturers Association (ARMA) c. Brick Institute of America (BIA) d. The American Plywood Association (APA) e. Local building department f. Architect or engineer g. Our new Cultured Stone® Flashing and Best Practices brochure, or visit www.culturedstone.com for a downloadable PDF ESTIMATING THE STONE REQUIRED Determine the amount of Cultured Stone® products needed by measuring the area to be covered. Measure the length times the height to arrive at the gross square footage of flat stone needed. Subtract square footage for window, door and other openings. Measure the linear feet of outside corners to determine the amount of corner pieces needed. One linear foot of corner pieces covers approximately 3⁄4 of a square foot of flat area. Subtract the flat area covered by the linear feet of corner pieces from the square footage of flat stone required. You may wish to obtain some extra stone to allow for cutting and trimming. In addition, be sure to verify whether the texture chosen is sold based on coverage with a 1⁄2" mortar joint or tight-fitted. Most texture coverages are listed for a 1⁄2" joint, the exceptions being Drystack Ledgestone, European Castle Stone, Pro-Fit® Ledgestone and Pro-Fit® Alpine Ledgestone. D. Metal Lath 1.

Starting Point Apply mortar and stone working from the bottom up, or most stones can also be applied from the top down. Working from the top down may help avoid splashing previously applied stone with dripping mortar. Ledgestone types should be installed from the bottom up. Figure 5 NOTE: Weather Conditions If stone is being applied in hot or dry weather, the back of each piece should be moistened with a fine spray of water or a wet brush to adequately prevent excessive absorption of moisture from the mortar. If being installed over concrete, masonry or scratch coat substrate, the substrate surface area should also be dampened before applying mortar. Applications should be protected from temperatures below 40°F as mortar will not set up properly under such conditions. Do not use antifreeze compounds to lower the freezing point of mortar. See International Building Code Section 2104.3 for cold weather construction requirements. A. Mixing Mortar/Grout Using Premixed Type N mortar or components from Table 2, mix to a firm, moist consistency. Mortar that is too dry and crumbly will not provide proper bond. Mortar that is too wet will be weak and messy. Table 2 – Proportions for Mortar Parts By Volume Wainscot Cross Section Watertable/Sill Stone Use a 2" x 4" leveling strip for a straightedge. Remove upon completion of stonework. MORTAR Watertables/sills provide a transition piece between a stone wainscot and other exterior finishes and for water runoff. They can also be used as a windowsill. Install using galvanized metal support brackets (Simpson Strong Tie A-21 or other galvanized right angle bracket with holding capacity minimum 5 lbs./LF) fastened with galvanized nails or screws penetrating studs 1" at a minimum of 16" on center. Use construction adhesive to bond stone at bracket locations. Caulk and flash as required at Watertable/ Sill locations using an approved corrosion-resistive flashing that extends to the surface of exterior wall finish and is installed to prevent water from re-entering the exterior wall envelope. Galvanized Wood Screw See page 6 for additional instructions concerning Pro-Fit Ledgestone, Pro-Fit® Alpine Ledgestone and European Castle Stone. Spread Cultured 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. Mixing Cultured Stone® wall veneer from different boxes during application will allow you to achieve a desirable balance of stones on your finished project. WATERTABLE/SILL INSTALLATIONS Caulk or Flashing as Required* Cultured Stone® Product at Exterior Level PREPARE YOUR WORK AREA Lap and install 3.4-lb. 3 ⁄ 8" rib, paper-backed, expanded metal lath to studs using nails which penetrate a minimum of 1" at 4" on center.

Regular mortars can be tinted to complement your Cultured Stone® product using iron oxide pigments available from your dealer. Watertable/Sill Stone Galvanized Metal Bracket, Holding Capacity 5 Lbs/LF Galvanized Wood Screw Lath Mortar Setting Bed Cultured Stone® Product ® B. Joint Width In order to obtain the most natural look, joints should be as narrow as possible. The average should not exceed 1⁄ 2" in width. An attractive look can also be achieved by fitting stones tightly together if desired. If using tight fit/drystack method, it is important to make sure scratch coat/backing has been covered completely by the setting bed of mortar. This will conceal the scratch coat/backing and prevent pockets from forming behind stones that could trap water. * Failure to properly caulk and/or flash as described in these installation directions may result in water damage to the structure. INSTALLING STONE AT GROUND LEVEL Keep the finished edge of the Cultured Stone® product a minimum of 4" above grade if earth or 2" above pavement. Use a 2" x 4" leveling strip (straightedge) or weep screed (Fig. 5). This will: Mortar Mortar • Provide drainage as required by applicable building code. • Avoid possible staining of the stone by soils containing alkali or other minerals. Figure 8 Ledgestone Types When applying ledgestone types, keep joints as small as possible to maintain a natural look, and install from the bottom up. Strike joints deeply, being careful not to expose the back edge of stones or scratch coat/backing. Mortar applied to the entire back of the stone. Care must be taken to avoid smearing mortar on surface of stone. Accidental smears should be removed using a whisk broom only after mortar has become crumbly. See page 6 for additional instructions regarding Pro-Fit® Ledgestone, Pro-Fit® Alpine Ledgestone and European Castle Stone. D. Install Corner Pieces First If your application requires corner pieces, apply these first. Notice that the corner pieces have a long and a short leg. Alternate these in opposite directions (Fig. 9). GROUTING AND FINISHING JOINTS A. Grouting Joints If additional mortar is required, use a grout bag to fill in joints (Fig. 14). Care must be taken to avoid smearing mortar on surface of stone. Accidental smears should be removed only after mortar has become crumbly using a whisk broom or dry bristle brush. Never use a wet brush or wire brush. Figure 9 Apply corners— alternating long and short legs in the opposite directions. Figure 6 4 Figure 7 Apply mortar using a mason’s trowel. Figure 14 Grout joints. E. Install Flat Pieces After the corner pieces are in place, flat pieces are applied working toward the wall center (Fig. 10). F. Keep Your Mortar Joints Consistent B. Finishing Joints When the mortar joints have become firm or “thumb-print” dry (setting time will vary depending on wall surface and climatic conditions), they should be pointed up with a wood stick or metal jointing tool. Rake out excess mortar, compact and seal edges around stones (Fig. 15). Careful attention to proper and even jointing will result in a professional looking finish. Figure 10 Apply flat pieces. Figure 15 Finishing the job. C. Cleaning Finished Job At the end of the work day, or when mortar is sufficiently set up, the finished job should be broomed or brushed to remove loose mortar and to clean the face of the stone. A wet brush should never be used to treat the mortar joints as this will cause staining that will be difficult, or impossible, to remove. Do not use acid or acid-based products. Figure 11 Apply mortar using a plasterer’s trowel. Trim with a hatchet. River Rock and Stream Stone When applying River Rock or Stream Stone, plan the placement of stones to minimize trimming and cutting to maintain the natural look of the rounded shapes. Place the individual stones close together, creating uniform joints between them. Cut and trim as required to achieve consistent width in the mortar joints. Then trim and fit small pieces into any remaining voids (Fig. 11). Concrete Block Metal Lath Figure 13 Trim with widemouth nippers. NOTES: Level and Plumb Joint Lines When applying Cobblefield® manufactured stone veneer, European Castle Stone, Limestone or ledgestone, endeavor to maintain level and plumb joint lines. Also, long rectangular pieces will look most natural if applied horizontally. C. Setting the Stones 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. Ensure complete coverage between the mortar bed and back surface of the stone. Mortar may also be applied to the entire back of the stone (Fig. 8). When stone is installed correctly, scratch coat/backing will not be visible. C. Applying Mortar to Prepared Surface Area Using a plasterer’s or mason’s trowel (Fig. 6 and 7), apply mortar 1⁄ 2" to 3⁄ 4" thick to prepared surface area. Do not spread more than a workable area (5 to 10 sq. ft.) so that mortar will not “set up” before stone is applied. Figure 12 Position large pieces first, then trim and fit in smaller pieces. 5 TYPICAL INSTALLATIONS: ADDITIONAL INSTRUCTIONS FOR PRO-FIT® LEDGESTONE, PRO-FIT® ALPINE LEDGESTONE AND EUROPEAN CASTLE STONE Wood Frame: Fit the Joints Tightly Install all these products with tight-fitted (mortarless) joints. Generally, components should be placed butting each other and aligned for level and plumb. When installing, the backs of all these components must be wet. They should be noticeably damp, but free from surface water. Mortar must be tinted to match the color of the stone you are installing to help conceal the joint lines. 1 2 6 3 4 5 A. Starting Point Products are applied starting from the bottom (first course) and working up. Start each course with the appropriate ledgestone component or European Castle Stone. Continue horizontally and complete each course before starting the next. If required, cut the appropriate size component to fit at the end or top of the finish area (Fig. 18).

Alternate these in opposite directions (Fig. 16). 3 4 5 7 6 Figure 16 Apply corner pieces— alternating long and short legs in the opposite direction. In sequence: (1) rigid foam insulation, (2) weather-resistant barrier, (3) metal lath, (4) scratch coat, (5) mortar setting bed, (6) Cultured Stone® manufactured stone veneer, (7) mortar joint. Masonry or Concrete: (Ledgestone texture shown) 1 C. Setting the Stones Press each stone into the mortar setting bed firmly enough to squeeze some mortar out around the mortar groove at the back edge of component. Apply pressure to the component to ensure a good bond. Ensure complete coverage between the mortar bed and back surface of stone. Mortar may also be applied to the entire back of the stone. Check for level and plumb. 2 3 D. Install Flat Pieces After the first corner piece is in place, the adjoining flat pieces of each course or pattern are applied. Using a trowel, strike off the excess mortar around the edges of the component prior to placing the next component. This will allow the next adjacent component to fit tightly (see Fig. 17). Choose the correct length component to ensure that vertical joints do not line up. In sequence: (1) mortar applied directly to untreated, unpainted masonry, concrete or stucco, (2) Cultured Stone® manufactured stone veneer, (3) mortar joint. Corner Preparation: 1 Figure 17 Strike off extruded mortar from edge before placing next component. (Pro-Fit® Ledgestone shown) 2 3 Top of wall C. Cutting and Trimming Hearthstones Hearthstones can be cut as required using a circular saw fitted with a carborundum or diamond blade or using a mason’s brick or tile saw. Place finished edges at exposed areas. SAFETY GLASSES AND A DUST MASK SHOULD ALWAYS BE WORN WHEN CUTTING ANY CULTURED STONE® PRODUCTS. End of wall (Ledgestone texture shown) Figure 18 Small Grinder (left) Circular Saw (right) NOTES: Hearthstone Installation UL Listed Cultured Stone® manufactured stone veneer and hearth products are made from non-combustible materials (UL Listing #209T). They are listed by Underwriters Laboratories, Inc., for use as floor protectors and wall shields with stoves and on fireplace hearths. To comply with UL Listing, mortar joints must not exceed 1⁄ 2" in width and the mortar must be even with the top of the hearth surface. CUTTING SHOULD BE DONE OUTSIDE AS SOME DUST WILL OCCUR. SAFETY GLASSES AND A DUST MASK SHOULD ALWAYS BE WORN WHEN CUTTING ANY CULTURED STONE® PRODUCTS. Stones can also be cut and shaped using wide-mouth nippers or a hatchet. Raised Hearth Do not cantilever or extend Hearthstones more than 11⁄ 2" beyond direct support. When grouting the extended portion of a cantilevered Hearthstone, bring the grout to the front edge. Push a long galvanized nail horizontally into the grout to add support, then cover the nail with mortar. Additional Information on Cutting and Fitting Finished Edges — Place finished edges at exposed areas. Cut Edges — Place cut edges within courses. Finishing Joints The design simplicity of Pro-Fit® Ledgestone, Pro-Fit® Alpine Ledgestone and European Castle Stone allows for easy installation of components and provides a finished, mortarless joint between the stones. This reduces the time required for cutting, grouting and jointing. Sealing Fireplaces/Hearths If desired, sealing the Cultured Stone® facing or hearth of a fireplace installation will assist in the removal of smoke and soot stains should they occur. See “Sealers” in General Information section for more information (page 8). Cultured Stone® Electrical Box Stones Installation Instructions Surface Cleaning Care must be taken to avoid smearing mortar on the surface of components. Accidental smears should be removed with a whisk broom or dry bristle brush only after mortar has become crumbly. Do not use a wet brush or a wire brush. Careful attention to proper jointing will result in a professional looking finish. Do not use acid or acid-based products, powerwashing, sandblasting or wire-brush cleaning.

(1) wall substrate, (2) weather-resistant barrier, (3) metal lath. 2 If joints need additional mortar, fill joints using a grout bag. Tool and finish joints following previous instructions under “Grouting and Finishing Joints.” Ensure Hearthstones are set in a complete bed of mortar. 7 Salt and De-Icing Chemicals Because all concrete and masonry are vulnerable to damage by salt, Cultured Stone® products are not warranted against damage incurred from salt or other chemicals used to remove snow or ice. Do not use de-icing chemicals on areas immediately adjacent to a Cultured Stone® manufactured stone veneer application. Tuscan Lintel Installation Instructions Method One On installations where the top of the opening provides no support for the bottom edge of the Tuscan Lintel: Install metal support brackets as per Cultured Stone® Installation Instructions for Watertables/Sills. Then install Lintel stones in a full setting bed of mortar in accordance with Cultured Stone® Installation Instructions. Scuffing Scuffing occurs on all natural stone. Occasionally some scuffing will occur on the surface of Cultured Stone® products. This can enhance the natural appearance of your Cultured Stone® manufactured stone veneer installation. Some scuff marks can be removed by cleaning as described above. Method Two On installations where the bottom edge of the Tuscan Lintel will be supported by a window or door frame’s molding or profile: Install lintel stones in a full setting bed of mortar in accordance with Cultured Stone® Installation Instructions. Make sure you do not cause deflection to window with weight of Lintel. If there is any question, use method one. Efflorescence Efflorescence is a water-soluble salt that is deposited on the surface of stucco, concrete, brick and other masonry products by the evaporation of water that has penetrated the wall. On rare occasions efflorescence will occur on Cultured Stone® products. To remove efflorescence, allow the stone to dry thoroughly, then scrub vigorously with a stiff bristle brush and clean water. Rinse thoroughly—do not use a wire brush. For more difficult efflorescence problems, scrub thoroughly with a solution of 1 part white household vinegar to 5 parts water. Rinse thoroughly. For unusually difficult cleaning problems, contact your local Cultured Stone® dealer. Terra Craft® Patio Paver Installation Instructions Base Preparation • Using a flat shovel, spade or sod cutter, remove sod and enough soil to accommodate the materials you are about to add. Base preparation materials will vary depending on soil type and local building codes. The cleared area should extend approximately 6" beyond final perimeter. • Using a hand or power tamper, compact the area to be paved. • Add approximately 2" of small gravel or screenings. Compact again. • Edge stones will require some type of restraint to prevent them from shifting, and that material should be installed next. Products commonly used for this purpose are: wood, plastic or metal edging, concrete or mortar. Sealers Sealers are not necessary on Cultured Stone® products. However, some customers use sealers to help prevent staining in applications prone to smoke, soot, dirt or water splashing. If you choose to use a sealer, make sure it is a silane-based, breathable sealer. Take note that sealers may darken the color of the stone. A sealer may also slow the natural movement of moisture out of the stone and increase the possibility of efflorescence and/or spalling. For information regarding actual performance or application of sealers, contact the manufacturer of the sealer directly. Sand Bedding Preparation • Spread one inch of sand over your base. • Using a piece of wood, level the sand by dragging it over the top to “screed.” This works best if you set up screed guides to hold the wood at the proper height as you slide it over the sand. Remove the screed guides when the sand is level and fill in any holes left by them. • Don’t walk on the level sand. Your finished job will only be as good as the sand bedding preparation. Swimming Pools Cultured Stone® products should not be used below water level, as in swimming pool liners. Chlorine and other chemicals may discolor the Cultured Stone® products and other masonry materials. Installing the Pavers • Using a string as your guide, begin installing the pavers in the pattern you desire. INCORPORATE GOOD BUILDING PRACTICES Building Code Requirements Building code requirements vary from area to area. Check with local authorities for building code requirements in your area. Carefully read all Installation Instructions before proceeding with your Cultured Stone® manufactured stone veneer application. • Set the pavers hand tight, checking frequently to assure you are running straight and have good spacing. • When all pavers are in place, sweep fine joint-filling sand over the paved area, making sure to fill all gaps. Exterior Applications Make sure that the application of Cultured Stone® products and the structure they are being applied to incorporate good building practices. Rigid, 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. On exterior applications, the incorrect installation or absence of flashing, cant strips, gutters and downspouts may result in diversion of water run-off onto finished surface areas. Masonry and other building products subjected to these conditions may develop staining and, when combined with severe freeze-thaw conditions, may eventually cause damage. The application of Cultured Stone® products under these conditions is not recommended. • Some customers use a vibratory plate compactor to set the stones. • Remove excess sand. • Backfill with topsoil and sod or seed as necessary. GENERAL INFORMATION Cleaning Dirt, etc., may be removed by using a strong 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. For help with serious cleaning problems, contact your local dealer. Do not attempt to clean using acid or acid-containing products, powerwashing, sandblasting or wire-brush cleaning. 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. Capping Off the Exposed Top of Exterior Walls To achieve a finished architectural look on horizontal or sloping top areas of exterior walls, piers, retaining walls or other surfaces, Cultured Stone® Capstones or a poured-in-place concrete cap must be used to provide adequate run-off protection to the wall areas. Caps should extend approximately 1"– 2" beyond the finished stone surface. Cultured Stone® corner pieces or flat pieces must not be used to cap walls. Retaining Walls All retaining walls must be waterproofed at the fill side. Wall construction should incorporate proper use of granular backfill and provisions for good drainage. A continuous longitudinal drain along the back of the wall set in drain rock is recommended. Chimney Cap All chimney chases must be capped with a one-piece cap that extends 1"–2" beyond the finished stone surface to prevent water from entering the wall system. Chimney or chase construction should incorporate proper flashing.
