Polymer Modified Adhered Veneer Mortar (PMAVM)
Ultimate Bond. Non Sagging.
SPEC MIX® Polymer Modified Adhered Veneer Mortar (PMAVM) is a technologically advanced adhered veneer mortar for use in bonding adhered manufactured stone veneer, natural thin cut stone and thin brick to a cementitious substrate. PMAVM is designed to provide excellent workability, cohesion, high bond strength, sag resistance, water resistance, efflorescence minimization, and durability. SPEC MIX PMAVM is the ideal solution for architects and contractors with projects where an immediate and ongoing need for mortar delivering high bond strength and sag resistance during installation is required. In applications where mortar joints are not utilized, such as dry stack applications, SPEC MIX PMAVM should be used to gain additional bond strength and “pop-off” protection. Installing natural thin cut stone veneer is aided by the unique anti-sag and high bond properties of SPEC MIX PMAVM.
SPEC MIX PMAVM meets the requirements of ASTM C 1714 and ASTM C 270 for Type S and N mortar including ANSI 118.4 (F-5.1.5) and TMS 402/602 shear bond standards. SPEC MIX PMAVM has been rigorously tested to reduce the probability of unit “pop-offs” and contractor call-backs to repair adhered veneer failures common with standard mortars. SPEC MIX PMAVM is available in standard and custom colors.
In addition to custom mix designs that are available for specific applications or properties, the SPEC MIX Polymer Modified Adhered Veneer Mortar is designed to be compatible with the characteristics of most all specified adhered masonry veneer units. It is acceptable for all types of construction: concrete, masonry, wood frame or steel studs, with submittals available upon request.
SPEC MIX PMAVM TEST RESULTS: SHEAR BOND AND WORKABILITY STUDY
• PMAVM exceeds code requirements for ASTM C482 shear bond by 560 percent – 330 psi in 28 days.
• PMAVM achieves 428 psi shear bond strength in 28 days when tested in using ANSI 118.4 (F-5.1.5).
• Exceeds open time, sag and adjustability requirements of ANSI 118.4.
• Can be used to apply stones directly to concrete or masonry surfaces.
SPEC MIX® Polymer Modified Adhered Veneer Mortar is available in 80 lb. (36.3 kg.) packages for easy hand loading or in 3,000 lb. (1,360.8 kg.) reusable bulk bags to be used with the various SPEC MIX® silo systems.
