EXAMINATION
A.
Do not begin installation until substrates have been properly prepared.
B.
If substrate preparation is the responsibility of another installer, notify Architect of
unsatisfactory preparation before proceeding.
PREPARATION
A.
Clean surfaces thoroughly prior to installation.
B.
Prepare surfaces using the methods recommended by the manufacturer for achieving the
best result for the substrate under the project conditions.
CRACK REPAIR
A.
Mar-flex Staple Kit Installation:
1.
Crack Injection must be performed prior to applying the staples.
a.
Allow for full cure of injection product before stapling.
2.
Laying out the job/Preparing the wall:
a.
Measure the length of cracks and divide into 24 inch (610 mm) segments. Note:
There must be no more than 24 inches (610 mm) between segments.
b.
Mark locations making sure there are no obstructions that would interfere with
the planned staple locations.
c.
Hold staple over the determined location at the appropriate angle and mark.
See Design Guide to determine the correct orientation of each staple according
to angle and nature of the crack.
d.
Using a 1 inch (25 mm) diameter masonry drill, make a hole 1 inch (25 mm)
deep at each mark.
e.
Using a 3 inch (76 mm) chisel, prepare the concrete surface around the holes
and where the stitch will attach. For proper adhesion, the wall surface within
this space must be free of paint and as smooth as possible.
3.
Application of the Staple:
a.
Load the double-cylinder epoxy cartridge into the dual applicator and "burp" the
03100-8
b.
c.
d.
e.
f.
g.
B.
3.4
cartridge so that an even flow of material exits both cylinders.
Attach the static mixing nozzle.
Fill two holes and apply a coat of epoxy between them in the area under the
staple to be installed. Put as much adhesive as needed to make a smooth, flat
layer 1/8 inch (3 mm) thick.
Position staple over the two holes.
Push the staple into the epoxy until it touches the wall. Press the material to
force the epoxy completely up through the grids of the staple.
Trowel epoxy evenly over the staple. Ensure that epoxy penetrates the grid and
covers the staple completely.
Use a trowel to push epoxy to fill gaps and unfilled spaces. Staples must be
completely covered with epoxy when finished.
Injection:
1.
Installing Universal Surface/Corner Mounts and Low-Pressure Drill-In Ports:
a.
Lay down crack injection drop cloth and wire brush the surface area to remove
debris and roughen the surface.
b.
Place a paste cartridge in the injection gun and remove end caps. Inject just
enough into a stir dish to attach ports. Mix well with a putty knife or tongue
depressor.
c.
Apply surface paste adhesive to the base of each Universal Surface/Corner
Port, being sure not to cover the injection hole with the paste.
d.
Starting at the bottom of the crack, place ports every 8 to 10 inches (203 to 254
mm) apart over crack until reaching the top.
2.
Installing Low-Pressure Drill-In Ports:
a.
Use a 5/8 inch (16 mm) concrete drill bit to drill a 2 inches to 4 inches (51 mm
to 102 mm) deep hole at a 15 to 30 degree angle intersecting the crack. You
will feel a slight release of pressure when your drill bit intersects the crack.
b.
Repeat ever 8 inches to 10 inches (203 mm to 254 mm) alternating from side to
side until entire crack is drilled. Use a can of compressed air to remove
concrete dust from drilled holes.
c.
Insert the black-sleeved end into the drilled hole. No other parts are needed.
3.
Surface Paste Application:
a.
Feather paste out a minimum of 2 inches (51 mm) wide over the crack and
build up 1/4 inch (6 mm) around each port. Allow paste to cure. To accelerate
curing a heat gun may be used. Do not begin injection until surface of paste
resists a putty knife impression.
4.
Injection:
a.
Begin injection at the lowest port, injecting with slow consistency until product
begins to flow from the port above. Begin injecting the next port and so on up
the crack. Keep injection gun parallel to the port during the process.

If fluid stops flowing through the static mixer and pressure increases on
the trigger, this could be a sign of dust clogging up the flow of product in
the crack. At this time, relieve pressure off gun, cap off port and move to
next port.
2)
If a "blow out" during injection occurs, inject the area with Quick Set
Urethane Adhesive.
b.
Allow product to set up for a minimum of 24 hours.
c.
If removal of the ports and paste is required, use a chisel and a hammer to port
and paste. A grinder/sander may be used.
CONCRETE CONTROL JOINT INSTALLATION
A.
After the control joint extrusions are placed, reinforcing bars (4 each #4) shall cross the joint
and extend a minimum of 4 feet (1219 mm) each side. This will prevent the control joint from
opening in a vertical line, to maintain aggregate interlock in the crack and structural integrity
03100-9
of the wall.
3.5
3.6
B.
After concrete placemen and initial cure, carefully remove the reusable control joint
extrusions with the foundation wall forms.
C.
Wire-brush the surface area of the control joint before applying sealant to rid surface of dirt,
dust, form oil, grease or any other foreign material.
D.
With a conventional caulk gun or trowel, apply sealant into the exterior of the control joint
from the top of the footing up to the grade line. Fill joint until it is flush with the surface of the
wall and then feather out onto both sides 2 inches (51 mm). Dry tool with light pressure
immediately after applying.
E.
Press the fiberglass reinforcement fabric into the sealant before curing occurs. Apply fabric
on the exterior of the control joint from the top of the footing to the grade line.
SEALER INSTALLATION
A.
Install in accordance with manufacturer's instructions.
1.
Agitate sealer before application.
2.
Do not dilute sealer.
B.
For vertical application:
1.
Application Method: Spray.
a.
Apply a single application of sealer with low pressure spray equipment (15 psi
or .1 MPa).
b.
Use a fan spray nozzle for greatest efficiency.
2.
Application Method: Broom.
3.
Application Method: Roll.
4.
Apply material from the bottom of the wall upwards so that it will run down the surface
at least 6 inches (152 mm) below the spray pattern.
5.
For porous vertical substrates or for maximum protection, apply two "wet-on-wet"
applications of sealer.
C.
Horizontal Application
1.
Application Method: Spray.
2.
Application Method: Broom.
3.
Application Method: Roll.
4.
Material shall be sufficiently applied to completely flood the surface; approximately
125 sf/gal (3 m2/l) depending on the porosity of the surface.
5.
Typically the surface can be re-opened to traffic in 1 to 2 hours, if the temperature is
72 degree F (22 degree C) or above.
6.
Full chemical reaction will take 3 days.
ADHESIVE ANCHOR INSTALLATION
A.
Install in accordance with manufacturer's instructions.
B.
For anchoring of bolts, dowels, rebar etc. the depth of the hole shall be approximately 9 to
15 times the bolt diameter. The whole space around the bolt in the hole shall not exceed 1/8
inch (3 mm).
C.
Drilled holes should be cleaned with a bristle brush. Remove all water and dust with clean
compressed air prior to installation. Air and surface temperature must be 40 degrees F (4
degree C) or above.
D.
Dispense into anchoring hole filling from the bottom up until full.
03100-10
E.
3.7
3.8
Insert the bolt, dowel or anchor turning it slowly during insertion. After insertion, the hole
shall be completely full of epoxy.
FABRIC FLASHING INSTALLATION
A.
Surface Preparation:
1.
Ensure that all surfaces are dry, smooth and regular, free from defects and excessive
dust.
2.
Concrete surfaces shall be smooth and without large voids, spalled areas or sharp
protrusions. Concrete shall be cured a minimum of 14 days and shall be dry before
transition strip is applied.
3.
Prime surfaces to receive fabric flashing using the primer. Apply primer with a roller,
brush or spray equipment at a rate of 100 to 300 sf/gallon (2.45 to 7.35 sq. m/l)
depending on porosity and texture of the surface. Allow primer to dry prior to fabric
flashing installation.
B.
Application:
1.
Overlap fabric flashing a minimum of 2 inches (51 mm) onto both surfaces. When
properly aligned, roll back and remove protective film. Place transition strip against
surface by pressing firmly with a hand roller. When using the transition strip with brick
ties, position strip, press in place and then cut for ties and protrusions. Seal around
openings and exposed edges with the mastic.
2.
Fabric flashing is not designed to perform as a permanently exposed flashing. Limit
exposure to approximately six weeks.
PROTECTION
A.
Protect installed products until completion of project.
B.
Touch-up, repair or replace damaged products before Substantial Completion.
