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, algae, mildew or other
contaminants before patching, topping, or placing overlays.
2. Surfaces should be a light broom finish or rougher to ensure
proper bond adhesion. Smooth troweled or dense concrete
surfaces must be mechanically roughened. For best results,
apply to clean surface with a concrete surface profile texture
between CSP 4 and CSP 6 as referenced in the International
Concrete Repair Institute (ICRI) Technical Guideline
No 310-2. Mechanical methods such as grinding,
shotblasting, scarifying, or sanding can be used to create
surface texture.
3. For soiled surfaces, scrubbing with a concrete cleaner,
degreaser, or detergent is recommended. Always rinse
thoroughly with clean water to remove all cleaning solutions.
A 2,500 to 3,500 pressure washer is also advisable to remove
all contaminants. Acid washing is not advised, it can damage
the existing concrete if not properly done.
4. All cracks or depressions greater than ¼ in. (6 mm) deep
should be repaired with a concrete repair product such as
Akona Vinyl Cement Patch (sold separately) at least three
days prior to resurfacing to allow the repairs to properly cure.
Minor blemishes (less than ¼ in. deep) may be repaired with
Polymer-Modified Concrete Resurfacer mixed to a trowelable
consistency 2-4 hours before applying overlay.
5. For sloped applications, no forms are needed for toppings of
⅛ in. (3 mm). Use removable form boards or other slope
guides for thicker toppings.
6. If possible, divide work areas into sections no larger than 100
-140 sq. ft. (9.29-13 m
2
). Expansion joints and control joints
will often form natural breaking points. Expansion and control
joints must be maintained, do not fill with the Resurfacer.
Weather stripping or duct tape can be used to prevent
spillage of the Resurfacer into these joints and surrounding
areas.
7. 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. No
bonding additive is needed.
2. Mix only the amount that can be applied within the 10-20
minute working time.
3. Add approximately 3¾ pt. (1.77 L) of clean, cool water per 25
lb. (11 kg). Always stir the powder into the liquid for easier
blending. Mix with a paddle mixer on a drill or mechanical
batch mixer. Avoid high-speed mechanical mixing which can
entrap air into the mixture. A 5-gallon pail can work well as a
mixing container, and can be used to pour the mixture onto

3. PRODUCT DESCRIPTION
Akona Polymer-Modified Concrete Resurfacer is a special
acrylic polymer-modified cement used to resurface spalled
and/or damaged interior and exterior concrete surfaces such
as garage floors, sidewalks, patios, and steps. Can be applied
in a flowable consistency using a long-handled squeegee or in
a stiffer consistency using a trowel. Develops a tough bond
and dries to a concrete gray color. It may be trowel or broom
finished and is designed for applications from ¼ in. (6 mm)
down to ⅛ in. (3 mm).
Features and Benefits
• Refinish and renew old concrete surfaces
• Polymer-modified, just add water, mix, and use
• Trowel or broom finish
• Apply from ¼ in. (6 mm) down to ⅛ in. (3 mm) thickness
• On average, allows light foot traffic in 4-6 hours, wheeled
traffic in 12 hours
When/Where to Use
• Interior/exterior concrete
• Steps, patios, garage floors
• Renew concrete surfaces
