1.5 SYSTEM DESCRIPTION
NOTE ** Select the appropriate system from the list below
and delete the others.
NOTE **
NOTE ** Parex Standard and Premium systems are PB systems,
which is a class of EIFS where the base coat varies
in thickness depending on the number of layers of
reinforcing mesh, with a minimum thickness of 1/16
inch (1.5 mm). In PB systems, the reinforcing mesh
is embedded into the base coat at the time of
installation. Both Standard and Premium systems
are available with a cementitious base coat or a
synthetic base coat.
NOTE **
NOTE ** Parex I-C Silver and I-C Gold systems are PM
systems, which is a class of EIFS where the base
coat is applied to a uniform thickness that can
range from a nominal 1/4 inch (6 mm) to 3/8 inch (9
mm). Both the I-C Silver and the I-C Gold systems
use a polymer modified base coat, but the I-C Gold
system uses mechanical fasteners to secure extruded
polystyrene insulation to substrate.

1. Parex EIFS Standard System with Cementitious Base
Coat, consisting of Expanded Polystyrene Insulation
(EPS) Board, Adhesive, Cementitious Base Coat with

Coat, consisting of Expanded Polystyrene Insulation
(EPS) Board, Adhesive, Full Synthetic Base Coat with
embedded Reinforcing Mesh, Primer (Optional), and
Finish Coat.
3. Parex EIFS Premium System with Cementitious Base
Coat, consisting of Expanded Polystyrene Insulation
(EPS) Board, Adhesive, Cementitious Base Coat with
embedded Reinforcing Fabric Mesh, Second Base Coat
