ADHERED VENEER MORTAR (AVM)

THE VERSATILE, DURABLE THIN VENEER MORTAR.

SPEC MIX Adhered Veneer Mortar (AVM) is a specially formulated mortar for bonding lightweight manufactured thin veneer masonry units over wood frame and steel stud construction. It contains an optimal blend of dry cementitious materials, masonry sand, and performance enhancing admixtures specifically designed for use as a scratch coat, bond coat and joint grout for thin veneer masonry units. It is formulated as a cohesive material with consistent workability, anti-sag formulation, high water retention and excellent bond strength. The final wall system will produce a non-load bearing, aesthetically pleasing exterior veneer or interior finish ideal for residential construction.

SPEC MIX AVM is designed to be compatible with the characteristics of most masonry thin veneer units. Packaged in 80 and 3,000 Ib bags, AVM is available in SPEC MIX standard colors and custom colors for joint grouting the masonry veneer system.

SPEC MIX AVM meets ASTM C 270, ASTM C 1714, CSA A179 and TMS 402/602 applicable requirements. Project submittals are available upon request; data sheet, SDS and standard color options are available here.

POLYMER MODIFIED ADHERED VENEER MORTAR (PMAVM)

THE LOW SAG, HIGH PRODUCTIVITY & BOND MORTAR.

SPEC MIX Polymer Modified Adhered Veneer Mortar (PMAVM) is a technologically advanced adhered veneer mortar for use in bonding manufactured stone veneer, natural thin cut stone and thin brick to cementitious substrates. PMAVM is formulated to provide excellent workability, water resistance, efflorescence mitigation, durability and high bond strength. SPEC MIX PMAVM is the ideal solution for owners, architects and contractors that demand a low-sag mortar with great working time that speeds up installation and productivity. The anti-slip properties of PMAVM make the installation of large natural thin cut stone easy while holding units in place for an extended time.

With PMAVM on the job building owners and installers can rely on the benefits of a controlled product and increased efficiency resulting in extensive labor savings. SPEC MIX PMAVM has the flexibilty characteristics that can accommodate movement in the wall while maintaining the integrity of the veneer system.

SPEC MIX PMAVM meets ASTM C 270, ASTM C 1714, CSA A179, ANSI A118.4 and TMS 402/602 applicable requirements. Project submittals are available upon request; data sheet, SDS and standard color options are available here.

THIN VENEER ADHESION MORTAR – XP500

THE MIX WITH EXTREME BOARDLIFE AND BOND

SPEC MIX Thin Veneer Adhesion Mortar XP500 is a premium preblended polymer modified thin set mortar specifically designed to bond masonry thin veneer units including manufactured and gauged or ungauged natural thin stone and thin brick to substrates for interior and exterior installations. Its innovative, anti-sag formulation and optimized sand gradation provide superior workability, adhesion and durability crucial to the application.

XP500 should not be used in a scratch coat over lath or a joint grout application. SPEC MIX XP500 exceeds ANSI A118.4 and ANSI A118.15 applicable requirements as well as TMS 402/602 Building Code Requirements and Specification for Masonry Structures shear strength requirements when tested in accordance with ASTM C 482. Project submittals are available upon request; data sheet and SDS is available here.
