EPOXY Healer-Sealer is a two-component, low viscosity, consolidating,
translucent, epoxy-acrylic resin coating that heals and seals concrete
surfaces. When used as a flood coat, EPOXY Healer-Sealer fills fine cracks
and penetrates the concrete to form a protective sealer that increases the
wear resistance of the concrete surface.
• Bridge decks
• Parking decks
• Airport runways & taxiways
• Columns and beams in splash zones
• Industrial concrete floors
• Primer for subsequent epoxy or urethane deck coatings
• Cures quickly
• Consolidates porous and dusting surfaces
• Provides protection from salts and chemicals
• Reduces water absorption of the concrete
• All surfaces must be dry, clean, and free from loose sand, dirt, dust, oil,
grease, sealers, paint, existing coatings, and other foreign substances
that could interfere with adhesion.
• Concrete must be at least 28 days old, and must have reached a
minimum 3,000 psi (20 MPa) compressive strength. Repair all spalled
areas of concrete using a suitable concrete repair product such as
• Remove all contaminants and open surface and cracks by shot-blasting
or sandblasting to a minimum concrete surface profile (CSP) of 3 - 4 per
the International Concrete Repair Institute (ICRI) Guideline No. 301-2R2013.
• Remove any remaining dust and debris in cracks and on concrete
surface by blowing off with oil-free compressed air.
• Clean steel surfaces to white metal according to SSPC SP 5.
• Hot surfaces should be cooled and shaded while cold surfaces should
be heated and sheltered.
• Epoxy-acrylic resins are temperature sensitive and care should be taken
to condition all components to between 65°F to 85°F (18°C to 29°C)
prior to mixing and placement.

• The volume mixing ratio is 4 parts A to 1 part B (4A:1B). Carefully mix
each part individually and then accurately measure out the correct
volumes of component A and component B before combining together.
Mix for at least 3 minutes using a low speed drill with a jiffy mixing
blade or paddle. Occasionally scrape the sides of the container while
mixing. For best results, mix at slow speeds (300 – 500 rpm) to prevent
entraining air, and continue until a homogeneous mixture is achieved. Do
not mix in an up and down motion.
• EPOXY Healer-Sealer is a thermosetting product. After mixing, apply all
material immediately! Do not leave EPOXY Healer-Sealer in the mixing
Read all instructions thoroughly prior to installation.
• Only proceed with application when the temperatures remain between
40°F and 90°F (4.4°C and 32°C) and protect from freezing for 6
hours after application. Do not apply EPOXY Healer-Sealer in wet weather
or if rain is imminent. Coating should not become wet within 6 hours
after application. To reduce outgassing, outside temperatures should be
falling (installation should be done in the late afternoon) and coating
should be applied at least 5°F (3°C) above the dew point.

• Swiftly pour mixed material over the concrete and quickly distribute
EPOXY Healer-Sealer evenly over the area to be treated.
• Allow EPOXY Healer-Sealer dwell time of 10 minutes so that it has time
to penetrate into the concrete and fill cracks. If material is absorbed to
quickly, a second application will be necessary.
• After 10 minutes, use a squeegee or broom to move all excess material
(that has not been absorbed) into the next area to be treated. Continue
• After 20 minutes, broadcast dry, #20 mesh sand at a rate of 2 lb/yd².
• Allow to cure until no longer tacky.
• Remove all excess sand by sweeping and using dry compressed air.
When used as a finished surface:
• Allow EPOXY Healer-Sealer to cure to touch until no longer tacky
[typically 5 – 6 hrs at 74°F (23°C)].
• Curing time will vary, depending on surface and air temperatures. Cool
temperatures will extend the working and curing time. High temperatures
will shorten the working time and curing time.
• Ensure all areas are entirely tack-free and all sand is completely bonded
to EPOXY Healer-Sealer before opening to pedestrian or vehicular
EPOXY Healer-Sealer can also be used as a primer prior to application of
certain epoxy or urethane coatings:
• Contact Aquafin Technical Services for approval and instructions.
EQUIPMENT: Uncured material can be removed with approved solvent.
Cured material can only be removed mechanically.
MATERIAL: Collect with absorbent material. Flush area with water. Dispose
of in accordance with local, state and federal disposal regulations.
• Do not thin or dilute.
• Do not use on cracks greater than ¼” wide. Contact Aquafin Technical
Surfaces for wide crack pre-treatment recommendations.
• Do not mix more material than can be used within 20 minutes [based on
• Substrate temperatures should be a minimum of 40°F (4.4°C).
• Once containers have been opened, use material as soon as possible.
• Consult Aquafin Technical Department when mixing or placing outside
of the temperature recommendations listed.
• EPOXY Healer-Sealer is translucent and is not designed to be an
aesthetic product. Variations in substrate porosity, repair materials, and
substrate discoloration will contribute to the end look of the finished
