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. Apply only to surfaces that are frost-free and above 40°F (4°
C) and below 100°F (38°C) within 24 hours of application and
72 hours thereafter and when rain is not predicted to fall on
the surface for 24 hours after application.
3. Just prior to application, pre-dampen surface to be repaired
with clean water to saturated surface dry (SSD) condition with
no standing water remaining.
Note: It is the responsibility of the installer/applicator to ensure
the suitability of the product for its intended use.
Mixing
1. Use cool, potable water, clean tools and clean containers.
Always stir the powder into the liquid. Mix complete contents
of the bag in a wheel-barrow, bucket, mortar box, or
mechanical mixer.
2. Begin with approximately 1 gal. (3.8 L) of clean, cool water
per bag.
3. Mix product thoroughly to achieve a stiff, lump-free, putty-like
consistency, approximately 2-3 minutes. Avoid high speed
mechanical mixing which can entrap air into the mixture. If the
product becomes firm before application, re-mix to proper
consistency. If required, add additional water sparingly, up to
a total of 1½ gal. (5.7 L) liquid per 50 lb. (22.7 kg) powder.
4. Optional: For improved durability, strength, and adhesion
when applying over previously coated and non-porous
surfaces it is recommended to use Akona Concrete Bonding
Additive in place of water (sold separately). Concrete Bonding
Additive may be diluted by up to ⅓ with water, however, for
extra difficult restoration or waterproofing projects, it is
recommended to be used at full strength.
5. Warmer temperatures will reduce the working time. The
addition of cold water at high temperatures, or warm water in
low temperatures will aid in adjusting the mix temperature.
Application
• Dampen the wall surface prior to applying product with a
water spray. If the wall becomes dry before application of
product, re-wet the wall. The dampened walls are important in
establishing a strong bond.
• This product should be applied between ⅛ in. (3 mm) up to ½
in. (13 mm) thickness. When multiple lifts or layers are
required, apply next layer once product is firm, but not
reached final set (approximately 2-4 hours) between lifts.
Make sure to dampen the surface area between applications
of product.
• When troweling, be sure to clean the surface of the trowel
often with water and use a “light touch” when finishing the
surface. Do not over trowel. Protect the surface from use until
surface is completely hard and set. Clean up with soap and
warm water as soon as application is completed.
Patching or Filling Holes in Concrete/Masonry Walls &
Stucco Repair:
• Crack-Resistant Surface Bonding Cement is ideally suited for
patching or filling holes in concrete or masonry walls, as well
as, repairing cracks or filling openings in stucco walls.

3. PRODUCT DESCRIPTION
Akona Crack-Resistant Surface Bonding Cement is a specially
-formulated, multi-use product. It can be used to build and
restore retaining walls or block walls, patch large vertical holes
where non-sagging cement is a must, or repair deteriorated
stucco. Because it contains special fibers it will not shrink,
crack, or sag on a vertical repair. Provides additional overall
strength vs. conventional concrete. Mix with water or for
additional strength and adhesion, mix with Akona Concrete
Bonding Additive (sold separately).
Features and Benefits
• Superior bond
• Polymer-modified
• Trowelable to feather edge
• Excellent durability, interior or exterior
• Just add water, mix, and use
When/Where to Use
• Moisture resistant
• Glass fiber reinforced for durability
• High strength
• Controls shrinkage, cracking, and sagging on vertical repairs
• Just mix with water or a bonding additive and use
