USES:
XPS and EPS adhesive on concrete and masonry when applicable.
Base Coat for the following Parex EIF systems:
I-C Gold
I-C Silver

COMPOSITION:
Binder base: Copolymers emulsion, compatible with portland cement
Water-based: VOC compliant
Color: Light grey

KEY PHYSICAL PROPERTIES:
Bond strength:
As a Base Coat on expanded and extruded polystyrene, bond strength exceeds tensile strength of insulation board.
Impact strength (EIMA 101.86):
50 in. lbs. with Parex Standard Mesh, 90 in. lbs. with Parex Intermediate 10 mesh.
Water penetration resistance (ASTM E-331):
20 lb/ft², pass.
Freeze-thaw resistance:
Uniform Building Code acceptance criteria; passes.
Puncture resistance (ASTM E 719-80):
50% to 100% more than typical PB EIF systems.

COVERAGE:
As a base coat, approximately:
60 ft² (6m²) for two coats.
As an adhesive, approximately:
Parex 5/8 in. (16mm) notched trowel:
100 - 120 ft² (9 - 11m²) /bag

CONTAINER:
60 lbs. (27.2 kg) net weight in multi-wall moisture-resistant bags.
Storage: Protect from sun and moisture at all times.
Shelf Life: One year if protected from sun and moisture.

WORKING TIME:
Sets up in 1-3 hours after mixed. Working time is affected by humidity and temperature.

DRYING TIME:
Full bond strength is reached after 1-4 days, depending on humidity and temperature.

CLEAN-UP:
Water soluble prior to drying. Clean tools and containers with water before mixture sets.

MIXING:
Equipment: Use clean container free of foreign substances; 400 - 500 r/min. 1/2 in. (13mm) drill with Jiffler type paddle.
Add 6 - 7 quarts (5.7 - 6.7L) of clean cool water to an empty pail. Add I-C One Base Coat and mix to a homogenous consistency. Allow 5 minutes set time then remix using small amounts of water to adjust the workability.
Parex I-C One Base Coat should be used immediately after tempering.
No additives of any kind such as portland cement, rapid binders, anti-freeze, accelerators, fillers, pigments, etc., shall be added under any circumstances.
Parex I-C One Base Coat may be retempered once, up to 45 minutes after it is initially mixed.

ADHESIVE APPLICATION:
Apply the adhesive to the entire surface on one face of the insulation board using a Parex 5/8 in. (16mm) notched trowel for masonry and concrete surfaces. The ribbons should be of uniform thickness, run horizontally and reach the perimeter of the insulation board. To ensure high initial grab and uniform adhesive contact, apply insulation board to wall with firm pressure to entire surface. Sufficient pressure must be applied to flatten adhesive ridges.
Note: For applications over gypsum sheathing, contact Parex Technical Services Department.

BASE COAT APPLICATION:
Using a stainless steel trowel, tightly apply the I-C One to the rasped surface of the insulation board to a uniform thickness of 1/16 in. (1.5mm) to 1/8 in. (3.1mm).
Lay Parex Standard Mesh 355 immediately on the wet Base Coat and trowel it into place without covering it over by embedding.
When the first layer is dry to the touch, trowel a second layer of Base Coat and level to achieve a full Base Coat thickness between 1/8 in. (3mm) and 5/32 in. (4mm). The mesh should be fully embedded and the pattern of the mesh should not be visible beneath the surface of the I-C One.
Parex Intermediate Impact 10 mesh, where used, should be installed with edges butted. Lap seams with Parex Short Detail mesh 356.
The base coat must be dry and hard prior to applying Parex Primer 310 or 313.
