5. INSTALLATION
Preparation
Read all directions before starting work. Proper surface
preparation is crucial to achieving a successful application.
1. Remove all loose or unsound materials. Thoroughly clean
surface of dirt, dust, grease, paint, or other contaminants
before patching, topping, or placing overlays.
2. Holes should be chipped out creating a new substrate to
ensure proper bond adhesion.
3. When reinforcing steel is present, it must be free of rust.
Mechanical abrasion or abrasive blasting should be used to
remove rust from reinforcing steel.
4. Large overhead or vertical patches deeper than 2 in. (51 mm)
should contain reinforcing steel. New steel should be inserted
using appropriate techniques of none is present.
5. Just prior to application, pre-dampen surface to be repaired
with clean water to saturated surface dry (SSD) condition with
no standing water remaining.
6. To improve bonding, a “slurry coat” (a thin soupy mixture of
Instant Patching Cement mixed with water or bonding
additive) can be applied to the pre-dampened surface just
prior to placing the trowelable mixture. Apply with gloved
hand or brush. Allow the slurry coat to become tacky, but not
fully dried. Trowel freshly mixed Instant Patching Cement
over the damp slurry coat and finish as required.
Note: It is the responsibility of the installer/applicator to ensure
the suitability of the product for its intended use.

3. PRODUCT DESCRIPTION
Akona Instant Patching Cement is a high-performance cement
used for filling wide cracks and other concrete and masonry
repair needs. It sets rock hard in just 90 minutes. Instant
Patching Cement self-bonds to all properly prepared concrete
surfaces and develops twice the strength of ordinary concrete.
For repairs from ⅛ in. (3 mm) to 1 in. (25 mm) per application
neat, and can be extended to a maximum of 5 in. (127 mm).
Mix with water or for additional strength and adhesion, mix with
Akona Concrete Bonding Additive (sold separately).
