|
| |
- Expanded self-furred metal lath

of 3.4 pounds per square yard, and galvanized.
|
| |
- Accessories: all corner reinforcement / aid,

joints shall be galvanized steel and per drawings/specifications.
- Fasteners: Comply with ASTM C-1063,
or UBC, whichever is more stringent, for type and
size of fastener required to rigidly secure materials
in place.
PART III - EXECUTION PREPARATION:
- All work shall be performed
by skilled craftsmen, experienced in this type of
work.
- Examine substrate to insure that
finished surfaces will be true, level, and plumb without
requiring additional or uneven thickness of coatings.
Verify that concrete and masonry are free of dust,
loose particles, oil and other foreign matter which
would adversely affect the bond of base coat. Notify
the proper authority, in writing, of any discrepancies
found in the substrate. Beginning of installation
indicates acceptance of existing conditions.
- Concrete/Masonry: Apply a bonding/sealing
agent to concrete and masonry before application of
base coat. Apply the bonding agent in accordance with
manufacturers instructions.
INSTALLATION:
Install Rapid Set® EISENWALL®
Premium Stucco System per manufacturers guidelines
for application. Installation shall comply with UBC
except as modified in ICBO ER-5102.
- Weather Resistant Barrier: Install
two layers of type D building paper complying with
UBC 14-1. Building paper shall be applied horizontally,
with the upper layer lapped over the lower layer a
minimum of four inches. At vertical joints, a minimum
lap of six inches is required. Stagger joint spacing
of both layers of building paper. Application of the
barrier must comply with section 1402.1 of the code.
- Metal lath and accessories: Install per UBC and ASTM C-1063, whichever is more stringent.
|
| |
- Install trims prior to application of metal lath.
- Metal lath shall be discontinuous under all control joints and expansion joints, providing
free-floating panels.
- Install corner reinforcement/aid at all exterior corners.
|
| |
- Mix and proportion Rapid Set® EISENWALL® Cement per manufacturers application guidelines.
- Apply basecoat by hand trowelling or gun application, in one coat, to 3/4" thickness,
using sufficient pressure and mechanical force, to embed metal lath, fill all spaces behind metal lath,
and provide a mechanical key with metal lath.
*** Alternatively, basecoat can be
applied in two coats, 3/8" thickness each, with
the second coat being applied as soon as the first
coat has attained sufficient rigidity to accept the
mechanical force of application without damage.
- Over concrete and masonry, apply
basecoat in one coat to 1/2" thickness. Base
coat shall be brought out to grounds, straightened
to a true surface, and finished with sufficient texture
to assure adequate bond with finish coat.
- Moist cure basecoat for minimum
2 hours by providing light fog of clean, potable water
as needed to maintain wet sheen.
- Apply specified finish coat to
1/8" thickness, per manufacturers guidelines/instructions,
as soon as basecoat is sufficiently hydrated. Basecoat
may require light misting to ensure even suction.
Apply finish coat evenly and consistently in order
to achieve uniformity in color and texture.
- Tolerances: Maximum variation
from true flatness: 1/8" in 10ft.
- Complete all work in the same
plane and panel each day, Do NOT stop short, such
as at expansion joints, etc.
ACCEPTANCE:
- Upon completion, clean up overspray/spatters,
remove all tools, equipment and unused materials.
Remove all trash and protective masking, and clean
all material from joints. Leave the work area in a
clean, orderly state.
