SURFACE PREPARATION
SeaShield FX-70 Jackets
Surface must be at least 35°F (2°C) prior to application. All surfaces must be sound, free of loose rust, marine growth, oil,
and other contaminants. Consult a qualifi ed professional engineer in all cases when section loss exceeds 25% only.
Concrete: Prepare surface by high-pressure water-blasting or other mechanical means to meet ICRI Guideline 310.2R
CSP 6-9. Repair or replace any reinforcing steel as determined by a qualifi ed professional engineer.
Steel: Prepare surface by high-pressure water-jetting or other mechanical means necessary to meet SSPC-SP12/
NACE 5 WJ-4. Repair or replace any structural steel elements with excessive section loss as determined by a qualifi ed
professional engineer.
Wood: Prepare surface by high-pressure water-blasting or other mechanical means necessary to achieve a sound
surface, free of all contaminants.
All submerged forms should be installed by certifi ed professional divers. All forms must be sealed appropriately to
prevent grout leakage during installation.
Formed applications: Concrete and reinforcing steel to receive repair mortar must be sound, clean, and free of all
contaminants that could impair product adhesion, bond, or performance. Concrete should be a minimum of 28 days
old or substantially cured to the equivalent design strength prior to SeaShield FX-225 installation. Prepare concrete
and reinforcing steel in accordance with ICRI Guideline 310.1R. Saw-cut the perimeter of the repair area, taking care to
avoid cutting any reinforcing steel. Remove all loose or deteriorated concrete by chipping hammer, water jetting, or other
mechanical means to reach sound concrete and achieve an open pore structure and surface profi le per ICRI Guideline
310.2R CSP 5-9, taking care to avoid micro-cracking. Remove all corrosion, rust, and surface contaminants from
reinforcing steel by sandblasting or other mechanical means. Remove all cleaning media and debris by water jetting,
vacuum or blowing with high-pressure, oil-free air.
Forming: Forms must be liquid tight to prevent leakage during installation. Use appropriate sealants or putties to seal
all surfaces to prevent leaks. Use an appropriate release agent prior to erecting forms to improve release. Do not allow
release agent to be applied to any non-formed surfaces as it can inhibit the bond of SeaShield FX-225.
MIXING
For optimal product performance, condition to 70°F (21°C). Do not prepare more material than can be used in the
working time of the product. Mix with a mortar mixer or a low-speed (300–600 rpm) drill and mixing paddle. For best
results, start with 90% of total mixing water and slowly add entire contents of SeaShield FX-225 while mixing to avoid
clumping. Adjust using remaining 10% of total mixing water until desired consistency is achieved scraping unmixed
material from the sides and bottom of mixing container as needed to ensure all material is mixed. Consult the
printed instructions on the product package for the maximum recommended amount of mixing water. Mix for
approximately 3 minutes. Do not re-temper. Continue to slowly agitate to prevent product from setting in the mixer up to
the maximum working time of 30 minutes at 75°F (24°C). SeaShield FX-225 can be extended with ³⁄ in. (9 mm) pea gravel
up to 30 lb. (13.6 kg) per bag, and requires the use of a mortar or grout mixer with stationary barrel and moving mixing
blades. Aggregate used must be nonreactive, clean, well graded, and saturated surface dry (SSD), have low absorption
and high density in compliance with ASTM C1260, C227 and C289. Do not use limestone aggregate.
LIMITATIONS
• Do not apply in water temperatures below 40°F (4°C)
• Do not apply in water temperatures above 90°F (32°C)
• Underwater product placement should
only be attempted only by certifi ed and
experienced diving contractors
• Underwater placement by pump or tremie only
• Always follow ACI 305 and 306 for hot or
cold weather installations for best results
beyond published recommendations
• Not designed as a leveling mortar, must be formed
• Do not mix partial bags
• Avoid contact with aluminum surfaces
• Site conditions can greatly affect cure
times and product performance

APPLICATION
SeaShield FX-70 Jackets
For pumping applications, pump properly mixed SeaShield FX-225 as follows: Install pumping ports at 90 degrees
from tongue-and-groove joint, alternating sides. Place the fi rst port approximately 1 ft. (30 cm) from the bottom of
the jacket. Place subsequent ports at a maximum 5 ft. (1.5 m) vertical spacing, alternating sides. Begin pumping
from the lowest port and move up from port to port. Do not exceed 10 ft. (3 m) pumping distance from any individual
port.
For tremie applications, make sure the hose extends all the way to the bottom of the form. Fill the form to the
desired level, allowing water to displace from the top of the form. Depending on the head pressure, depth of pour,
and size of the vessel, the tremie hose may need to be retracted as the form fi lls to maintain fl ow.
All submerged jackets should be inspected by a certifi ed professional diver during the fi lling process to check for
leaks and proper placement.
Formed applications, below water
For pumping applications, pump properly mixed SeaShield FX-225 as follows: Install pumping ports as required
for the repair. Begin pumping from the lowest port and move up from port to port making sure the form is completely
fi lled and the water is displaced. Do not exceed form design pressure rating.
For tremie applications, make sure the hose extends all the way to the bottom of the form. Fill the form to the
desired level, allowing water to displace from the top of the form. Depending on the head pressure, depth of pour,
and size of the vessel, the tremie hose may need to be retracted as the form fi lls to maintain fl ow. Do not exceed
form design pressure rating.

CAUTION
May cause serious eye and skin irritation or damage. When combined with water, may cause moderate to severe alkali
burns. Contains silica; do not breathe dust.
Protective Measures: The use of safety glasses and chemical-resistant gloves is recommended. Use appropriate
clothing to minimize skin contact. The use of a NIOSH-approved respirator is required to protect respiratory tract when
ventilation is not adequate to limit exposure below the permissible exposure limit (PEL). Refer to Safety Data Sheet,
please contact Winn & Coales (Denso) Ltd for an SDS.
