3. Product Description
BASIC USE
SPEC MIX Stone Veneer Mortar
SPEC MIX Stone Veneer Mortar is a preblended dry material specifically designed to bond thin masonry veneer units to solid base surfaces, such as masonry, concrete or galvanized, expanded metal lath. The final wall system will produce a non-load bearing, aesthetically pleasing exterior veneer or an interior finish ideal for concrete or masonry walls, stud walls or metal buildings. Good workmanship, coupled with proper detailing and design, ensures durable, functional, watertight construction.
SPEC MIX Polymer Modified Stone Veneer
Mortar (PMSVM)
SPEC MIX Polymer Modified Stone Veneer
Mortar (PMSVM) is a technically advanced mortar used to bond thin veneer masonry units to a substrate. It is an ideal solution for architects and contractors having projects with an immediate and ongoing need for mortar delivering high bond strength and sag resistance during installation. The non-sag formulation provides excellent workability, cohe-
From custom homes to commercial projects, SPEC MIX Polymer Modified Stone Veneer Mortar is the ultimate material when building with adhered stone veneer masonry.
sion, high bond strength, water resistance, efflorescence minimization and durability. For applications in which mortar joints are not utilized, such as dry stack applications, SPEC
MIX PMSVM can be used to gain extra bond strength and pop-out protection.
SPEC MIX PMSVM meets the requirements of ASTM C270 for Type S and N mortar, including appropriate ANSI 118.4 and ACI 530 shear bond standards. It has been rigorously tested to reduce the probability of unit "pop-offs" and contractor callbacks to repair failures common with inferior mortars.
COMPOSITION & MATERIALS
SPEC MIX Stone Veneer Mortar and Polymer
Modified Stone Veneer Mortar (PMSVM) are dry, preblended proprietary mixes containing cementitious materials, aggregates and special admixtures engineered to promote adhesion, reduce shrinkage and maximize product durability. When specified, a pigment can be preblended with either product to ensure color consistency in each bag.
SPEC MIX products are manufactured locally across the United States and Canada by licensed manufacturers who use specialized blending equipment and follow strict quality control procedures to meet project specifications, contractor expectations and applicable ASTM standards.
SIZES
SPEC MIX Stone Veneer Mortars are packaged in 80 lb (36.3 kg) bags and 3000 lb (1360 kg) bulk bags. They can be used with any SPEC MIX material delivery system for increased job site efficiency and safety.

ENVIRONMENTAL CONSIDERATIONS
All SPEC MIX products are produced locally within 500 miles of the job site. Empty bags and wooden pallets are returned to the plant for reuse, reducing landfill impact. Use of SPEC MIX products can contribute points toward LEEDª project certification.
5. Installation
PREPARATORY WORK
Deliver products in manufacturer’s original, unopened, undamaged containers with identification labels intact. SPEC MIX products are custom packaged to meet specification requirements. Handle and store product according to SPEC MIX recommendations.
Keep dry, covered and protected from weather and other environmental hazards that could cause damage. When stored and protected as recommended, SPEC MIX products have a 9-month shelf life.
Verify that site conditions are acceptable for installation. Do not proceed with installation until unacceptable conditions are corrected.
Mortar type should correlate to the particular masonry unit to be used, as certain mortars are compatible with certain masonry units. The specifier should evaluate the interaction of the mortar type and masonry unit specified.
Masonry units with a high initial rate of absorption will have greater compatibility with mortar of high water retention. The material properties that influence the structural performance of

330 psi masonry are compressive strength, bond strength and elasticity. Since the compressive strength of masonry mortar is of less importance than bond strength, workability and water retentivity, the latter properties should be given priority in mortar selection.
Mortar selection should be based on design requirements and with due consideration given to the code and specification provisions affected by the mortar selected.
Mock-Ups
A sample of the proposed product will be provided by the manufacturer for onsite preparation of a sample panel for architectural approval and testing, if required. Preparation of this panel with all materials and systems that will be employed in the final project is imperative. Retain the mock-up or field sample through the completion of the project.
METHODS
MIXING PMSVM: when mixing SPEC MIX PMSVM, use a mechanical batch mixer or an electric drill with a paddle to ensure homogeneity and good board life.
1. Add dry SPEC MIX PMSVM to clean potable water. Start with approximately
75% of the required water. (See Table 2 for details)
2. During 1–2 minutes of initial mixing, add remaining water as necessary, then let the mortar slake or set for approximately
5 minutes and then remix for 2 minutes.
3. Gauge the consistency of the mortar visually. A good workable mortar should have the consistency to be trowelable, but stiff enough to retain ridges and peaks when troweled on a horizontal or

vertical surface area.
4. The workability of the mortar can be adjusted as necessary by adding either more water or more powder prior to final mixing. Mortar shall be used and placed in final position within one hour after initial mixing or discarded after that time period. Whenever possible, do not retemper colored SPEC MIX masonry mortars by adding additional water; retempering may affect color consistency. SPEC MIX products are custom packaged to the specification. They must be kept dry, covered and protected from

weather and other damage.
MIXING Stone Veneer Mortar:
1. Use a mechanical batch mixer to ensure homogeneity, workability and good board life.
2. Add the minimum amount of clean, potable water for optimum workability
3. Mix for five minutes consistently from batch to batch.
4. Tool mortar joints when the surface is thumb-print hard. Keep tooling times consistent.
5. Hand mix mortar only with written approval by the specifier who should outline procedures.
6. Use mortar within 2.5 hours after initial mixing.
7. Retemper mortar only when mixing water is lost due to evaporation.
8. Do not retemper colored mortar.
Application Over Wood & Lath
• When installing over galvanized metal lath, tightly attach the lath to the substrate using
Engineered for optimal workability, bond strength and durability, SPEC MIX veneer mortars are superior nails every 6" (152 mm). To eliminate waves in the lath when attaching it to plaster board or painted surfaces, screw lath into studs every 8" (203 mm)
• Using a trowel, apply mortar 1/2" (12.7 mm) thick to prepare the surface so no lath is exposed
• To avoid setting or excessive water loss due to evaporation, apply mortar only in a working area less than 10 ft 2 (0.93 m 2 )
• Ensure that the lath is completely covered by the Polymer Modified Stone Veneer
Mortar or Stone Veneer Mortar
• Before the mortar begins to harden, use a scratcher, scarifier or notched trowel to
"scratch" the mortar surface
• After a 24-hour curing period, coat the back of each adhered masonry unit with sufficient mortar and press it firmly into place until the excess material spreads from the sides of the unit
• Once all units are in place, fill a grout bag with SPEC MIX Stone Veneer Mortar; fill each joint by extruding the grout from the bag
• Tool, brush or rake joints
Application Over Masonry and Concrete
• Prepare painted, waterproofed or dirty surfaces for mortar application by sandblasting and cleaning, or by attaching a
ASTM C847 compliant metal lath and applying a scratch coat of SPEC MIX Stone
Veneer Mortar or PMSVM
• Apply the mortar to the back of the masonry veneer unit surface at a minimum 1/2”
(12.7 mm) thickness
• Apply the unit directly to the masonry, concrete substrate or scratch coat until the excess material spreads from the sides of the unit
• Once all the units are in place, fill a grout bag with SPEC MIX Stone Veneer Mortar; fill each joint by extruding the grout from the bag
• Tool, brush or rake joints
PRECAUTIONS
• Do not use PMSVM when temperatures are below 40 degrees F (4 degrees C)
• Allow mortar to cure for a minimum of 28 days
• Do not use mortar 1 hour or more after mixing
• Clean mortar only with potable water—do not use muriatic acid
• Tool mortar joints when the surface is thumbprint hard and keep tooling times consistent
• Do not strike joints too early or too late, as the color will not remain consistent with the mockup panel
• Do not retemper colored Stone Veneer
Mortar or PMSVM by adding additional water as it will affect the final mortar color
