3. Product has a low viscosity and will penetrate into the cracks,
the base of cracks or underside of slabs may need to be
sealed prior to application. For best results, taping on each
side of a crack will give finished repair a cleaner appearance.
Note: It is the responsibility of the installer/applicator to ensure
the suitability of the product for its intended use.
Mixing
• Before using, condition material to 65°F-85°F (18°-29°C). Use
cartridge in standard caulking gun.
• Unscrew and remove both protective cap and plug from the
cartridge. Insert the flow restrictor, attach the static nozzle
mixer and tighten nut. Load cartridge into standard caulking
gun.
• Dispense a bead of epoxy until the color is uniform. The first
two or three dispenses are used to remove air and ensure the
correct mixing ratio, this material must be discarded. The
cartridge is now ready to use.
Application
• As a gravity-fed crack filler, create a vee-notched crack and
slowly inject the epoxy into the crack, filling the crack
completely.
• Disperse with deliberate slow and even pressure to allow
proper blending of the resin and hardener in the static mixing
nozzle. This material will be very fluid, dispersion that is too
fast or with too much pressure can cause an uneven mix that
may not properly harden.
• As a crack injection, set appropriate injection ports, then seal
ports and surface of crack with Epoxy Crack Repair. When
the epoxy seal has cured, slowly and steadily inject Epoxy
Crack Repair into injection ports.
• When the work is interrupted, the static mixer can remain on
the cartridge after the gun pressure has been relieved. Work
quickly, once material hardens in the nozzle, a new nozzle
must be used. Cartridge should remain upright to reduce the
risk of material draining from the nozzle.
Curing
Epoxy Crack Repair has a pot life of 3 hours (60g) at 77°F (25°
C). At temperatures below 77°F (25°C) this product will take
proportionately longer time to cure. At temperatures above 77°F
(25°C) it will take a proportionately shorter time to cure. Thin
layers (5 mil) will become tack-free in approximately 3½ hours
at temperatures of 77°F (25°C).
Clean Up
Epoxy Crack Repair should be wiped clean before it cures.
Once cured, epoxy crack repair can only be mechanically
removed. Avoid getting epoxy on skin.
Limitations
• For professional use only.
• Follow all industry standard safety procedures when handling,
such as chemical resistant gloves, eye and skin protection.
• Subject to discoloration upon exposure to UV light.
• Not for use in cracks subject to hydrostatic pressure.
• Maximum crack width is ¼ in. (6 mm).
• Maximum crack depth is 6 in. (150 mm).
• Do not add solvents or fillers to change viscosity of the
product.
• Per NTSB Safety Recommendations, the use of adhesive
anchors is prohibited in sustained overhead load anchoring
applications.

3. PRODUCT DESCRIPTION
Akona Epoxy Crack Repair is a two-component, low-viscosity,
100% solids, epoxy repair product designed for injection into
cracks in structural materials including concrete and bricks, for
the purpose of bonding and sealing them. Color will be clear to
light yellow. Designed for filling narrow cracks with maximum
width of ¼ in. (6 mm) to a maximum depth of 6 in. (150 mm).
Features and Benefits
• High-strength - stronger than concrete
• Low-viscosity - easy to inject and flows well into small cracks
• Moisture tolerant and blocks moisture
• Fits standard caulking tube
• No mess - self mixing
When/Where to Use
• Horizontal repairs
• Interior and exterior
• Stops air and water leaks
• Secures railings, bolts, and rebar
• Repairs foundation cracks
• Sets injection ports

5. INSTALLATION
Preparation
Read all directions before starting work. Proper surface
preparation is crucial to achieving a successful application.
1. Always remove all loose and unsound materials. Thoroughly
clean all surfaces of dirt, dust, grease, or other contaminants
which could interfere with bonding. Surfaces should be as
smooth as possible before installation.
2. For better adhesion concrete surfaces should be dry and
cured a minimum of 21-28 days from date of placement
depending upon curing and drying conditions. Surface and
ambient temperature must be 40°F (5°C) or above.
