3. PRODUCT DESCRIPTION
ProSpec
®
Heavy-Duty Stone Veneer Mortar is a high-yield,
lightweight, high-performance, one-component, Portland
cement-based, polymer-modified, fiber-reinforced mortar for
adhered installation of large natural stone and manufactured
masonry veneer stone. Special admixtures help create both a
mechanical and chemical bond to the substrate, significantly
outperforming standard mortars. ProSpec
®
Heavy-Duty Stone
Veneer Mortar is “Step 2” of the ProSpec
®
stone installation
system used to create decorative exterior or non-load bearing
interior veneer walls, both above and below grade and is 25%
lighter than traditional mortars with excellent handling
characteristics.
Features and Benefits
• Excellent workability, non-slump, and non-sag
characteristics
 Fiber-reinforced for increased flexural strength and crack
resistance
 High-yield with greater coverage than typical mortars, 40 lb.
(18.1 kg) bag yields as much as a 50 lb. (22.7 kg) bag of
conventional stone veneer mortar.
 Polymer-modified, mix with water only
• Convenient for small or large jobs
 Pre-blended for consistency between batches
 Extended open time
 High bond strength and impact resistance
 Reduces cracking and pop-offs
 Excellent resistance to water penetration and efflorescence
 Meets requirements of ASTM C 1714, ASTM C 270, ANSI
A118.4, A118.11, and ISO 13007-C2TES1P1
Uses
 Installing real or manufactured stone veneer units
 Interior or exterior
 Vertical application
 Above and below grade applications
For installation of:
 Natural stone veneer*
 Masonry veneer stone (cast and simulated stone)
* All natural stone should be tested to be sure discoloration by bleed-
through does not occur. Not intended for moisture sensitive or resin-
backed stone.
For installation over:
 Properly installed ProSpec
