3. PRODUCT DESCRIPTION
ProSpec
®
Polymer-Modified Stone Veneer Base Coat is used as
a scratch and base coat for real or manufactured stone veneer
units. Also referred to as a cement plaster coating, it is a blend
of cementitious materials, dried sand, and special performance
admixtures designed to produce a highly-bondable substrate
and to optimize consistency between batches. The special
admixtures help create both a mechanical and chemical bond to
the substrate, significantly outperforming standard Type S and
N mortars. ProSpec
®
Polymer-Modified Stone Veneer Base Coat
is “Step 1” of the ProSpec
®
stone veneer installation system
used to create decorative exterior or non-load bearing interior
veneer walls and can be applied over ProSpec
®
Moisture
Barrier or directly to fully cured concrete .
