Background:
The removal and restoration of deteriorated concrete and steel within beams, columns, decks and
adjacent walls will comply with the IRCI Guideline No. 03730 (a copy of which is attached hereto)
or as modified by Engineer as work progresses.
The anticipated work involves the initial demolition, and then the removal, replacement and
restoration of concrete and reinforcement as required. The degree of restoration is currently
unknown, until such time as the initial demolition has begun.
The anticipated sequence of repairs is as follows:
• Shoring required for repairs of all columns, beams and decks (if rle'q'ulred by engineer)
• Removal and restoration of concrete and reinforcement steel within beams, columns and
decks. (1CRI Guideline No. 03 73 0) , - I
• Minor chipping and patching of areas not requiring full depth repairs.
• Applied deck coating.
The following materials are approved for anticipated use in this restoration (see attached
manufacturers specifications):
• Sikacrete2ll Concrete Mix.
• SikaTop 123 PLUS.

The above sequence is general in nature and will be modified as restoration work progresses.
Observations of the initial demolition will determine any required modifications to the above
procedures and materials selected for the final restoration process.
Based on initial visual observations, repairs will not require shoring; however, in the event the
demolition work reveals that shoring will be required, the engineer will instruct the contractor to
shore the area as well as the number of levels required. The instructions given to the contractor will
be submitted to the Building Department with the final close-out documents.
We have been authorized by the Association to work with the contractor during the restoration and,
will inspect work partially completed as well as observe results of the new demolition prior to field
authorizing the repairs to be completed.
The proposed concrete restoration work, except as authorized by the engineer's modified
instructions, will comply with specifications outlined in the IRCI Guideline No. 03730, as well as
the applicable minimum building codes and the applicable fire safety standards as determined by
the local authority in accordance with Chapter 553 and Chapter 633 of the Florida Statutes where
applicable to concrete restoration.

GUIDE FOR SURFACE PREPARATION FOR THE REPAIR OF DETERIORATED CONCRETE RESULTING FROM REINFORCING STEEL CORROSION 310.1 R-2008
1,0 Introduction
This guideline provides owners, design profes-
�ionals, contractors,. and other interested parties
with a recommended practice for the removal of
deteriorated concrete caused by the corrosion of
reinforcing steel, including the preparation of the
removal cavity to provide a clean sound surface
to bond a repair material.
This guideline outlines removal geometry,
configuration, removal process, edge preparation,
reinforcement repair, surface preparation, and
inspection prior to placing a repair material. An
engineer should evaluate the impact of concrete
removal on structural capacity prior to performing
concrete removal and repair. The repair methods
involve saw cutting and concrete removal using
impact tools, hydrodernolition, and other removal
techniques. Special caution should be taken to
locate and avoid cutting or damaging embedded
reinforcing bars, prestressing strands, post -
tensioning tendons, or electrical conduits. Cutting
into these items can be life threatening and may
significantly affect structural integrity.
This guideline also contains a discussion of
concrete removal and preparation for the repair
of columns where the concrete is in compression.
Special consideration must be given to the repair
of concrete in compression as the load -carrying
capacity of the element may be permanently
compromised during the concrete removal and
preparation process.
While the procedures outlined herein have
been used to successfully remove concrete and
prepare the removal cavity on many projects, the
requirements for each project will vary due to
many different factors. Each project should be
evaluated individuallyto ascertainthe applicability
of the procedures described herein. Refer to ACI
50611-05, "Guide to Shotcrete'for surface prepar-
ation prior to shotcrete application.
2.0 Definitions
Anodic ring effect: Corrosion process in which
the steel reinforcement in the concrete surrounding
a repaired area begins to corrode preferentially
to the steel reinforcement in the newly repaired
area (sometimes referred to as the halo effect).
Bruised surface (micro -fracturing): A surface
layer weakened by interconnected microcracks
in concrete substrates caused by the use of high -
impact, mechanical methods for concrete
removal, and surface preparation; fractured layer

typically extends to a depth of 0.13 to 0.38 in.
(3 to 10 mm) and, if not removed, frequently
results in lower bond strengths as compared with
surfaces prepared with nonimpact methods.
Carbonation: The conversion of calcium ions
in hardened cementitious materials to calcium
carbonate by reaction with atmospheric carbon
dioxide. Carbonation reduces the pH of the
concrete and its ability to protect reinforcing steel
and embedded metal items from corrosion.
Chloride contamination: Contamination of
concrete with chloride ions commonly used in
deicing salts and accelerating admixtures such as
calcium chloride and sodium chloride. Chloride
contamination above the threshold for corrosion
can result in corTosion of the reinforcing steel.
Chloride threshold: The amount of chloride
required to initiate steel corrosion in reinforced
concrete under a given set of exposure conditions;
commonly expressed in percent of chloride ion
by mass of cement.
Corrosion: Degradation of concrete or steel
reinforcement caused by electrochemical or
chemical attack.
Nhcrocrack: A crack too small to be seen with
the unaided eye.
Tensile pulloff test: A test to determine the
�unit stress, applied in direct tension, required to
separate a hardened repair material from the
existing concrete substrate. The test may also be
used to determine the maximum unit stress that
the existing concrete substrate is capable of
resisting under axial tensile loading and the near -
surface tensile strength of a prepared surface
(refer to ICRI Technical Guideline No. 210.3-
2004 [formerly No. 03739] and ASTM C 1583).
Substrate: The layer immediately under.a
layer of different material to which it is typically
bonded; an existing concrete surface that receives
an overlay, partW-depth repair, protective coating,
or some other maintenance or repair procedure.
3.0 Exposure of
Reinforcing Steel
The practice of completely removing the concrete
(undercutting) from around the corroded
reinforcement no matterwhat degree of corrosion
is found, is keyto achieving long-term performance
of surface repairs. In most cases, complete
removal of the concrete from around the
reinforcing steel is the best practice, where
protection of the reinforcing steel within the

Nii INSTITUTE
repair cavity is achieved by providing a uniform
chemical environment around the reinforcing
steel. If noncorToded reinforcing steel is exposed
and the concrete is chloride contaminated,
removal of the concrete around the reinforcing
should occur or other corrosion -reducing means
should be considered. Reinforcing steel partially
embedded in chloride -contaminated concrete is
susceptible to future accelerated corrosion.
If, for structural reasons, the concrete cannot
be completely removed from around the corroded
reinforcing steel or if a corrosion inhibiting
system is not used, the repair may be compromised
due to continued corrosion. If there is a potential
trade-off between durability and structural
capacity, structural capacity should always take
priority. When reinforcing steel is not fully
exposed through the concrete removal and
preparation process, alternative corrosion inbib-
iting systems should be considered. These
systems may include use of corrosion inhibitors,
sacrificial anodes, or cathodic protection.
4.0 Anodic Ring
(Halo) Effect
The existing concrete surrounding a repair area
in chloride -contaminated or low pH reinforced
concrete is susceptible to accelerated corrosion.
This is due to the electrical potential differential
between the chloride contaminated or low pH
existing concrete and the chloride -free or
high pH repair material. This anodic ring effect
can result in accelerated corrosion of the
surrounding reinforcing steel leading to future
concrete deterioration. To assess existing concrete
conditions beyond the repair area, chloride
content and pH of the concrete at the level of the
reinforcing steel should be determined. Where
the chloride content exceeds the threshold level
for the initiation of corrosion or where the
reinforcing steel is susceptible to corrosion as a
result of carbonation, a corrosion inhibiting
system should be considered to minimize future
corrosion. Othermeasures may also be considered,
such as the application of sealers and coatings, to
slow the corrosion process. In severely chloride -
contaminated or carbonated concrete, the
complete removal and replacement of the
contaminated concrete at and beyond the repair
area may be necessary to provide a successful
long-term repair.
5,0 Removal
Geometry
Examples of the removal geometry for several
different types of reinforced concrete elements
are shown in Fig. 5.1 through 5.6. Repairs may
be located on horizontal, vertical, and/or overhead
surfaces. The removal in Fig. 5.5 and 5.6 is for
columns where the removal will not affect the
structural capacity of the column. Removal of
concrete within the reinforcing or to expose the
reinforcing (concrete in compression) is a special
condition and is discussed in Section 10.

6.0 Configuration
of Repair Area
Deteriorated and delanninated concrete should be
located and marked prior to starting the removal
process. Delarninated concrete can be located using
sounding or other suitable techniques. The repair
area should extend a minimum of 6 in. (15 2 mm)
beyond the actual delaminated concrete. Note that
during concrete removal, repair areas can grow
in size beyond the areas identified due to incipient
delaminations that are not readily identifiable
by sounding. Repair configurations should be
kept as simple as possible, preferably square or
rectangularwith square comers (Fig. 6.1). This may
result in the removal of sound concrete. Reentrant
comers should be minimized or avoided, as they
are susceptible to cracking.

impact breakers, hydrodemolition, or another
suitable method. Undercutting will provide
clearance upoer the reinforcing steel for cleaning
and full bar circumference bonding to the repair
material and the surrounding concrete. Bonding

the repair material to the full circumference of the
reinforcing steel will secure the repair structurally.
Provide a minimum of 0.75 in. (19 mm) clearance
between exposed reinforcing steel and surrounding
concrete or 0.25 in. (6 mm) larger than the coarse
aggregate in the repair material, whichever is
greater. Sound concrete may have to be removed
to provide proper clearance around the reinforcing
steel. If impact breakers are used for partial depth
concrete removal, the breaker should not exceed
30 lb (12 kg). A 15 lb (7 kg) breaker is preferred

Fig, 7.3: Abrasive blasting to clean

to minimize damage to the substrate, reinforcing
steel,and surrounding concrete.
Concrete removal should extend along the
reinforcing steel until there is no further delam-
ination, cracking, or significant corrosion and the
reinforcing steel is well bonded to the surrounding
concrete. Care should be taken to avoid significant
and sudden changes in the depth of concrete
removal, as the repair material is more susceptible
to cracking at these locations.
If noncorroded reinforcing steel is exposed
during the removal process, care should be taken
to not damage the bond to the surrounding
concrete. If the bond between the reinforcing
steel and concrete is broken, undercutting of
the reinforcing steel is required.
Remove all deteriorated concrete and additional
concrete as required to provide the proper
configuration and/or the minimum required
thickness of repair material as required by the
manufacturer of the repair material and/or the
project specifications.
7.2 Preparation of the
Repair Perimeter
The perimeter of the repair area should be saw
cut 0.75 in. (19 mm) deep to provide a vertical
edge (Fig. 7.2) for the repair material. This will
avoid featheredging of the repair material.
Depending on the repair material selected, the
depth of the existing reinforcing and the
manufacturer's recommendations, a saw cut depth
less than 0.75 in. (19 mm) deep may be sufficient.
Care should be taken to avoid cutting the existing
reinforcing steel.
7.3 Cleaning of the
Concrete Surface and
Reinforcing Steel
The use of high -impact, mechanical methods to
remove deteriorated concrete will result in a
surface layer weakened by interconnected micro -
cracks in the concrete substrate. The fractured
(bruised) layer can extend to a depth of 0. 125 to
0.375 in. (3 to 10 mm) into the resultant concrete
substrate and may result in reduced bond strength.
Remove the bruised layer and bond -inhibiting
materialssuch as diM concrete slurry, and loosely
bonded concrete by oil -free abrasive blasting
(Fig. 7.3) or high-pressure water blasting. The
4-310.111-2008 GUIDE FOR SURFACE PREPARATION FOR THE REPAIR OF DETERIORATED CONCRETE RESULTING FROM REINFORCING STEEL CORROSION
saw -cut edge of the repair area should also be
blasted to roughen the polished vertical surface
caused by the saw-cuaing.
All concrete, corrosion products, and scale
should be removed from the reinforcing steel by
oil -free abrasive blasting or high-pressure water
blasting. Verify that the reinforcing steel and
concrete surface are free from dirt, oil, cement
fines (slurry), or any material that may interfere
with the bond of the repair material. Inspect the
repair cavity to verify that all delaminations and
deterioration have been removed. If hydro -
demolition is used, cement fines (slurry) must be
completely removed from the repair surface. A
tightly -bonded light rust build-up on the reinforcing
surface is usually not detrimental to bond. If a
protective coating is applied to the reinforcing
steel, follow the coating manufacturer's recom-
mendations for steel surface preparation.
8.0 Inspection
and Repair of
Reinforcing Steel
Loose reinforcement should be secured in its
original position by tying to secure bars or by
other appropriate methods to prevent movement
during placement of repair material.
If reinforcing steel has * lost cross -sectional
area, a structural engineer should be consulted.
Repair reinforcing steel by either replacing the
INTaRNATIONAL
CRI FCGMCH�E AEPAIR
I N S T I T U T a
damaged/deteriorated steel or placing supple-
mental reinforcing steel in the affected section
(Fig. 8. 1). Supplemental reinforcing steel may be
lap -spliced or mechanically spliced to existing
reinforcing steel. The supplemental reinforcing
steel should extend (lap length) beyond the
damaged/deteriorated area in accordance with
ACI 318, "Building Code Requirements for
Structural Concrete."
9.0 Final Surface
Inspection
Immediately prior to placing the repair material,
inspect the repair cavity to verify that all bond -
inhibiting materials (dirt, concrete slurry, loosely
bonded aggregates, or any material that may
interfere with the bond of the repair material to the
existing concrete) have been removed. If bond -
inhibiting materials are present the repair cavity
should be recleaned as previously described.
To verify the adequacy of the prepared
concrete surface and completeness of bond -
inhibiting material removal, a tensile pulloff test
(ICRI Technical Guideline No. 210.3-2004 or
ASTM C1583) should be considered to evaluate
the bond strength capacity and tensile strength of
the existing concrete substrate. This test may also
be performed after the repair is complete. The
pulloff strength requirement should be established
by the engineer and included as a performance
specification for the repair.

Undercutting of reinforcement is a best practice
in tensile zones of concrete. In columns, the
primary loading condition is compression. From
a design perspective, the concrete section
contained within the reinforcing cage is considered
to carry the compressive loads (Fig. 10.1). The
concrete outside ofthe reinforcement is considered
as protective concrete cover for fire and corrosion
protection of the reinforcement. Removing e
concrete within the column reinforcing steel
(Fig. 10.2) can greatly increase the compressi . ve
stress in the reinforcing steel and the remaining
concrete. Upon concrete removal, compressive
load paths redistribute around the repair
(deteriorated) sections (Fig. 10.3). Depending on
the size of the concrete removal area behind the
column steel, buckling of the column vertical
reinforcing bars can occur. In the majority of
cases, shoring systems will not unload the
compressive stress in the column section.
When new repair material is placed in the
prepared area, the new material cures and most
materials undergo drying shrinkage, which results
in the new material being put into a tensile stress
state. The new material will not carry compressive
loads until the original concrete compresses further,
forcing the repair material into compression , If
further compression is beyond the capacity of the
existing concrete, failure of the column may
occur. This key concept affects the concrete
preparation process. In normal concrete repair
(other than columns), removal of the concrete
surrounding the corroding reinforcement (also
known as undercutting) is a normal and necessary
process to provide for a long-term durable repair.
To remove concrete around vertical reinforcing
steel in a column (removing concrete inside the
reinforcing bar cage) can cause the remaining
concrete and/or reinforcement in the column to
become overstressed. From a structural point of
view, this condition may not be desirable. If
concrete is to be removed inside the reinforcement
cage, a qualified structural engineer should
determine the impact of the repair on potential
reinforcement buckling and overall structural
capacity of the column. Note that the discussion
in this section is also applicable in concept to
compression zone portions of other structural
members such as beams, slabs, and walls (with
or without compression reinforcement) where
on -going compressive stress exists and where
adequate shoring cannot be installed prior to
repairsto prevent displacements and corresponding
stress redistributions during repairs.

How to Use
Substrate Concrete, mortar, and masonry products.
Surface Preparation Concrete: Remove all deteriorated concrete, dirt, oil, grease, and all bond -inhibiting materials
from surface. Be sure repair area is not less than I in. in depth. Preparation work should be
done by high pressure water blast, scabbler, or other appropriate mechanical means to obtain
an exposed aggregate surface with a minimum surface profile of ±1/8 in. (CSP-7). Saturate
surface with clean water. Substrate should be saturated surface dry (SSD) with no standing
water during application.
Reinforcing Steel: Steel reinforcement should be thoroughly prepared by mechanical cleaning
to remove all traces of rust. Where corrosion has occurred due to the presence of chlorides, the
steel should be high-pressure washed with clean water after mechanical cleaning. For priming of
reinforcing steel use Sika" Arniatecle 110 EpoGem (consult Technica I Data Sheet).
Priming For Priming of reinforcing steel use Sikaa` Armate& 110 EpoGern (consult Technical Data Sheet).
Mixing Place 4/5 of 1 gallon water in mixing container. Add Sikacreteo 211 while continuing to mix.
Add additional water up to 1 gallon total. Mix to a uniform consistency, maximum 3 minutes.
Mechanically mixwith a low -speed drill (400-600 rpm) and paddle orin appropriate size mortar
mixer or concrete mixer.
Application Form and pour or pump applications: Pre -wet surface to SSD. Ensure good intimate con-
tact with the substrate is achieved. To accomplish this, material should be scrubbed into the
substrate or other suitable means should be employed such as vibration of the material or
pumping under pressure. Vibrate form while pouring or pumping. Pump with a variable pres-
sure pump. Continue pumping until a 3 to 5 psi increase in normal line pressure is evident
then STOP pumping. Form should not deflect. Vent to be capped when steady flow is evident,
and forms stripped when appropriate.
Tooling & finishing As per ACI recommendations for portland cement concrete, curing is required. Moist cure
with wet burlap and polyethylene, a fine mist of water or a water based* compatible curing
compound. Curing compounds adversely affect the adhesion of following layers of mortar,
leveling mortar or protective coatings. Moist curing should commence immediately after fin-
ishing. Protect newly applied material from direct sunlight, wind, rain and frost.
*Pretesting of ctuing compound is reCommended.
Limitations is Application thickness: Minimum 1 in. (25 mm); Maximum 8 in. (200 mm)
a Minimum ambient and surface temperatures 45'F (7'C) and rising at time of application.
es Using Sikal-atexs, SikaLatex`D R or similar products will result in loss of slump and slump
retention. Field tests for suitability are strongly recommended.

Slka FerroGard 903
Sika FerroGardO 903
Penetrating, corrosion inhibiting, impregnation
coating for hardened concrete
Description
Sika FerroGard 903 is a corrosion Inhibiting impregnation coating for hardened concrete surfaces. It is
designed to penetrate the surface and then to diffuse in vapor or liquid form to the steel reinforcing bars
embedded in the concrete. Sika FerroGard 903 forms a protective layer on the steel surface which inhibits
corrosion caused by the presence of chlorides as well as by carbonation of concrete.
How It Works
Ska FemoGard 903 is a combination of amino alcohols, and organic and inorganic inhibitors that protects
both the anodic and cathodic parts of the corrosion call. This dual action effect dramatically delays the initia-
tion of corrosion and greatly reduces the overall corrosion activity.
Sika FerroGard 903 protects the embedded steel by depositing a physical barrier in the form of a protective
layer on the surface of the steel reinforcement This barrier inhibits corrosion of the steel.
Where to use
Slka FerroGard 903 is recommended for all steel -reinforced, prestressed, precast, post tensioned or marine
concrete. Use of Slka FerroGard 903:
• Steel -reinforced concrate, bridges and highways exposed to corrosive environments (deicing salts, weathering)
• Building facades and balconies
• Steel -reinforced concrete in or near a marine environment
• Parking garages
• Piers, plies, and concrete dock structures
• As part of Sike's system approach for buildings and Civil engineering structures
Advantages
Sika FerroGard 903 offers owners, specifiers, port authorities, DOTs, and engineers, a new technology i . n
corrosion inhibition that can easily be applied to the surface of existing concrete to extend the service life of
any reinforced concrete structure.
• Protects against the harmful effects of corrosion by penetrating the surface of even the most dense con-
crete and diffusing to the steel to inhibit corrosion.
• Enhances the durability of reinforced concrete.
• Does not require concrete removal.
• Environmentally sound.
• Does not contain calcium nitrite.
• Easily applied by either spray or roller to all existing reinforced concrete.
• Can be applied to reinforced concrete that already exhibits corrosion.
• Adds additional benefits when used prior to protective coatings in concrete restoration systems.
• Water based for easy handling and application.
• Not a vapor barrier; allows vapor diffusion.
• FerroGard has been proven effective in both laboratory (ASTM G1 091Cracked Beams) and field analysis.
• ANSIMSF Standard 61 potable water approved
Coverage
For normal concrete, application is 200 ft.2/gal. each coat. A minimum of two mats is always recommended..
For dense concrete, application may exceed 300 ft.2/gal. Therefore, more than two mats may be required
to achieve the total application rate: 100 ft.2/aal.
Packaging . 5 gallon palls with spout, 55 gallon drums.
How to Use
Surface Preparation
Before applying Ska FerroGard 903 be sure the surface is clean and sound. Remove all dirt, dust, oil,
grease, eflorescence or existing coatings from concrete surface by steam cleaning, waterblasting or slightly
sandblasting. AJJOW concrete surface to dry prior to application of Ska Fen-oGard 903. The dryer the surface
the better the penetration and effectiveness.

Sika FerroGard 903 is applied by roller, brush or spray on Concrete surfaces. When spraying, use a conven-
tional aidess spray system or hand -pressure equipment. A minimum of two coats Is always recommend -
ad. Dense substrates may require more costs. Mitling time between mats of Sika Ferrol 903 is at least
1 hour. Allow a minimum of one day to allow Sika FerroGard 903 to dry and penetrate.
When Sika FerroGard 903 is used prior to the application of a repair mortar, concrete overlay, protective
coating, Silkafloor system or any other application, care must be taken to remove any residue remaining on
the surface from the application of Sika FerroGard 903. Clean the substrate in such a manner Ct.e. push the
water in one direction away and off from the surface to be overcoated) to completely remove any residue.
Horizontal surfaces require pressure washing (2,000 psi minimum) to remove the residue. Vertical surfaces
may be rinsed Wth water or pressure washed. The use of Sika Armatec 110 EpoCem as a bonding agent
prior to the application of repair mortars or concrete overlays is suggested. Drying times depend on envi-
ronmental conditions, absorbency of the substrate and maximum recommended moisture content for the
subsequently applied system.
III Minimum ambient and substrate temperatures 35*17.
• Do not apply when temperature is expected to fall below 35'F within 12 hours.
• If the applied surfaces will be submerged after the application of Sika FemoGard 903, a waterproofing
coating must be applied prior to submersion.
• Substrate should be as dry as possible prior to the application.
• Protect glass, wood, brick, galvanized steel, Copper and exposed aluminum during the application.
• Maximum chloride content of concrete structures intended to be treated with Sika FerroGard 903 is 6 Ibs./y3
(measured at the level of the reinforcling steel). For levels up to 10 lbs./Y3, consult technical service.

Sikagard 701W
SikagardO 701W 1_1
Solvent -free, siloxane emulsion concentrate
Description Sikagard 701W is a solvent -free concentrate of silane modified siloxane emulsion. When di-
luted, the liquid forms a water and chlodde-ion repellent impregnation specifically formulated
to seal absorbent cementitious surfaces and other masonry substrates.
Where to Use a Men diluted, use Sikagard 701W as a colorless, non -vapor -barrier, water and chloride
ion -repellent impregnation for absorbent materials.
• Treat concrete bridges, roadways, runways, parapet walls, precast, beams, columns,
curbing, retaining walls, pavers, etc.
• Treat both new and existing structures.
• Treat masonry brickwork, stucco, etc.
• Porous architectural curtainwall panels.
• Use on steel -reinforced structures to reduce the corrosion and latent damage potential of
chlorides.
Advantages Sikagard 701W is both an economical and simple-ta-use sealer. Because of its unique
ability to decrease water and chlodde intrusion, Sikagard 701W helps reduce the danger of
rebarcorrosion.
Sikagard 701W:
• Meets the standards of acceptability for concrete sealers established in NCHRP Report#244.
• Enhances concrete integrity.
• Reduces efflorescence.
• Improves resistance to frost and deicing salts (chloride ion).
• Reduces dirt penetration.
• Does not act as a vapor barner.
• May be applied to alkaline substrates.
m Will not degrade under UV exposure.
Coverage 100-250 sq. ft./gal., (diluted concentrate) depending on porosity of substrate. For proven
results against chloride-jon intrusion, 125 sq. ft./gal. is recommended.
Packaging 5 gal. pail.
A300
How to Use -
Surface Preparation
Before applying Sikagard 7011N, be is
sure surface clean and sound. The best impregna-
tion is achieved on a dM very absorbent substrate. Remove all grease, curing compounds,
surface treatments, coating, oils, etc.
Preparation Work: Concrete and masonry surfaces, sandblast, high pressure water blast or
use other mechanical means.
Mixing
Dilute Sikagard 701W concentrate with tap water in an appropriately sized mixing container.
Mix with a low speed (400-600 rpm) drill with Sika paddle or comparable drum mixer until
uniformly blended. Make sure paddle is completely covered so as not to entrain air. For best
K: �,Mlt
results, Sikagard 701Wshould be remixed if unused24 hours afterblending with water.
Application
Apply by roller, brush (horizontal surfaces), or spray. Any pooling of water repellent indicates
overdosing on a dense substrate while rapid absorption indicates a porous substrate. Veda-
tions in concentration down to 8:1 for dense substrates or coverage area, and/or multiple
for be to
wet -on -wet applications porous substrates may utilized achieve optimal substrate
treatment. Preliminary site test application is recommended to determine effective coverage
and performance. Maximum water repellency is generally realized in 72 hours, but may
take longer depending
on surface and atmospheric conditions.
Limitations

PART 3 - EXECUTION
3.1
A. Concrete: Verifythatthework done underothersections
meets the following requirements:
I . That the concrete deck surface is free of ridges and
sharp projections. If metal forms or decks are used
they should be ventilated to permit adequate drying
of concrete.
2. That the concrete was cured for a minimum of 28
days. (Minimum of 3,000 psi compressive strength).
Water -cured treatment of concrete is preferred. The
use of concrete curing agents, if any, shall be of the
sodium silicate base only; others require written
approval by NEOGARDI�
3. That the concrete was finished by a power or hand
steel trowel followed by soft hair broom to obtain
light texture or "sidewalle finish..
4. That damaged areas of the concrete deck be restored
to match adjacentareas. Use70714170715-09 clear
100% solids epoxy and sand for filling and leveling.
3.2 PREPARATION
A. Cleaning: Surfaces contaminatedwith oil orgrease shall
be vigorously scrubbed with a stiff bristle broom and
a strong non-sudsing detergent such as NEOGARDO
8500 BioDegradable Cleaner. Thoroughly wash,
dean, and dry� Areas where oil or other contaminants
penetrate deep into the concrete may require removal
by mechanical methods.
B. Shot -Blasting: Required surface preparation method
for remedial construction is also the preferred method
for new construction. Mechanically prepare surface by
shot-blastingto industry standard surfacetexture (ICRI's
CSP3-CSP4) without causing additional surface defects
in substrate. Shot-blasting does not remove deep
penetrating oils, grease, tar or asphalt stains. Proper
cleaning procedures should befollowed to ensure proper
04-15-14 071813-2 Pedestrian Traffic Coatings
bonding of the deck coating.
C. AltematetoShot-Blasting: Ifshot-blasting is notpractical,
hydro blasting using minimum 4,000 psi at tip within 6"
of substrate is acceptable." Properdeaning procedures
must be followed to ensure proper bonding of the deck
coating.
D. Cracks and Cold Joints: Visible hairline cracks (less
than 11WIn width) in concrete and cold joints shall be
cleaned, primed as required and treatedwith thoroughly
mixed FC7500/FC7960 base coat material a minimum
distance crf 2" on each side of crack to yield a total
thickness of 30 dry mils. Large cracks (greater than
1/16" in width) shall be routed and sealed with 70991
or 70996 sealant. Sealant shall be applied to inside
area of crack only, not applied to deck surface. Detail
sealed cracks with thoroughly mixed FC7500/FC7960
base coat material a distance of 2" on each side of
crack to yield a total thickness of 30 dry mils.
E. Control Joints: Seal control joints equal to or less than
1" in width with 70995 urethane sealant. Depending
on the width to depth ratio of the joint, backing material
and a bond breaker may be required. Install sealants
in accordance with ASTM C 1193 and manufacturer's
instructions. Detail sealed joints with thoroughly mixed
FC75DO/FC7960 base coat material a distance of 2" on
each side of joint to yield a total thickness of 30 dry mils.
F. Flashing Tape: Install 86218 flashing tape and 86220
reinforcing fabric where indicated on the drawings
and/or where required by the manufacturer prior to the
application of base coat.
G. Surface Condition: Surface shall be dean and dry prior
to coating.
3.3 APPLICATION
A. Factors That Affect Dry Film Thickness: Volume of
solids, thinning, surface profile, application technique
and equipment, overspray, squeegee, brush and roller
wet out container residue, spills and other waste are
among the many factors that affect the amount of wet
coating required to yield proper dry film thickness. To
ensure that specified dry film thickness is achieved,
use a wet mil gauge to verity actual thickness of wet
coating applied, adjusting as needed for those factors
which directly affect the dry film build.
