Epoxy Coating For Concrete And Steel Marine Structures
Honest Coating, Marine Structures is an epoxy resin coating system consisting of a Base Coat and an optional
use, pigmented Top Coat. Both products are two - component, solvent free materials designed for two -coat
application on concrete, steel and wood marine structure surfaces. They may be applied above and below
the waterline and in both salt and fresh water environments. Typical applications include coating of concrete
piers, seawalls, dock floors, drainage ditches, abutments, sewer and outfall pipes; protection of steel
structure surfaces such as pilings, drilling rigs, production platforms, ship hulls, buoys, well jackets and
bulkheads; and, protective coating of wooden structures such as pilings, piers, shelters and power poles.
Honest Coating, Marine Structures bonds to properly prepared dry, damp, wet and submerged substrates and
cures to a tough, water resistant, impervious protective surface. The coating is freeze/thaw resistant and will
not embrittle but will acquire a chalky surface when exposed to sunlight. The standard color of Base Coat is
off-white; Top Coat is concrete gray (blue/gray).

Pigmented Top Coat for contrast with Base Coat
Bonds to dry, damp, wet and submerged substrates
For use in both salt and fresh water environments
Cures to a tough, water resistant, impervious surface
Does not embrittle when exposed to direct sunlight
Environmentally safe- No VOC solvents
Limitations: The recommended minimum substrate
temperature during installation and cure is 50 deg F. In
underwater end tidal zone applications, the coating may have
to be applied within a relatively short period of time (30 minutes
to several hours) after the substrate was cleaned to achieve an
adequate bond. Wave action may displace the coating if
exposure occurs before the coating has reached hard set. Do
not add solvents or otherwise thin this material.
Colors & Packaging: Base Coat, off-white; Top Coat,
concrete gray (blue-gray) Standard package sizes of Part A +
Part B are 2 and 10 gallons.
Chemical Resistance: Marine Structures provides excellent
resistance to salt and fresh water, salt solutions, gasoline,
kerosene, crude, fuel and mineral oil, most industrial waste
solutions and many other chemicals. It has limited resistance
to hydrocarbon solvents. Performance is a function of the
specific chemical and concentration, ambient and solution
temperature, exposure time and housekeeping procedures.
For information on specific chemicals and exposure conditions,
contact a ChemCo Systems, Inc., technical representative.
Surface Preparation Substrate surfaces may be dry, damp,
wet or submerged. Wet or dry sandblast to remove all loose
and deteriorated substrate material, other surface
contaminants such as tars, oils, paints, waterproofing
materials, rust, barnacles, etc., that may interfere with the
formation of a good bond. Cleaned concrete surfaces should
have a minimum strength of 200 psi in direct tension. Steel
surfaces should be cleaned to "white metal" according to
SSPC SP 5.
Mixing: Marine Structures are two-component systems. The
resin to hardener (Part A: Part B) mix ratio is 1:1, by volume.
Read all material safety data (MSDS) information before
handling the product. Wear safety glasses and clean neoprene
rubber gloves when handling the materials. Premix the
individual components before drawing from bulk packaging.
Transfer appropriate quantities of Part A and Part B into a
mixing container. Use quantities that can be applied before the
pot life of the mixed material expires. Blend thoroughly using a
Jiffy mixer blade attached to a low speed (350-750 rpm)
electric or pneumatic drill. Proper mixing will take 2-3 minutes.
Do not mix the material underwater.
ABOVE THE WATERLINE: Use normal techniques
applicable to viscous coating materials. Apply the material after
the daily substrate temperature cycle has reached its peak.
When the substrate is wet, use sufficient brush pressure to
displace the water with the coating.
BELOW THE WATERLINE: Apply with a brush using
slow, deliberate motion and sufficient pressure to displace the
water with the coating.
RECOATING: The recommended recoat window is 18-24
hours; Base Coat may be used for the second coat. The
pigmented Top Coat is an optional use material employed
when a second coat of contrasting color is desired. Top Coat is
most often used in applications with poor worksite visibility or
when a gray color is required.
