5. INSTALLATION
Preparation
Read all directions before starting work. Remove all loose or
unsound materials. Thoroughly clean all surfaces and
substrates of dirt, dust, grease, paint, or other contaminants.
Insulation Board/ ICF Treatment:
• It is recommended to roughen the surface of the insulation
board with a wire brush or rasp to ensure solid adhesion to
the surface.
• Prior to application of product, all fastener heads or
protrusions in the insulation board should be embedded into
the board.
Patching:
• Use a wide-blade putty knife to apply a layer of Foundation
Coating Cement over any joints or depressions. Immediately
place fiberglass mesh tape into the layer of fresh mortar and
embed the mesh with your wide-blade putty knife so the
surface of the insulation board is as uniform as possible.
• Allow any joint treatments to harden prior to final product
application.
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 25-35
minute average working time.
3. Mix one 50 lb. (22.7 kg) bag at a time in a wheel-barrow,
bucket, mortar box, or mechanical mixer. When mixing with a
drill, use a ½ in. (1.3 cm) drill rated at 300-450 rpm with a
square mortar paddle attachment. Using a drill rated higher
than 450 rpm can result in entrapping air which could lead to
pin holes in the finished patch.
4. Add 4 qt. (3.8 L) of clean water to the mixing container.
Always add powder to liquid to avoid lumps. While operating
drill mixer, slowly add the full bag of powder to water, mixing
until a smooth, lump-free consistency is achieved. Additional
water can be added sparingly to achieve proper consistency.
Total water used should not exceed 5 qt. (4.7 L).
5. Mix time should be between 2-3 minutes maximum at room
temperature with conditioned materials (50-80°F/10°-27°C).
Over mixing or over watering may result in decreased
strength and degrade the fibers. DO NOT USE A BONDING
AGENT, mix with water only. Do not add accelerators or
retarders.
6. 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
1. For best results, 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.
2. Do not apply in direct sunlight or hot, windy days or when
rain is forecasted within 24 hours.
3. Apply with a brush or trowel onto properly prepared insulation
board in thin coats of approximately 1/16 in. (1.5 mm)
thickness.
4. A second coat of 1/16 in. (1.5 mm) may be applied after 1
hour for additional protection on areas subjected to impact
damage or to obtain a heavier, textured appearance. Any

3. PRODUCT DESCRIPTION
Akona Foundation Coating Cement is a specially-formulated,
Portland cement-based product for coating and protecting
polystyrene insulation board or insulated concrete forms (ICF)
from weathering, ultraviolet rays, and general wear/impact.
Foundation Coating Cement is polymer-modified and contains
fibers which controls shrinkage and improves the adhesion
properties of the product. It is easy to apply by masonry brush
or trowel and has the superior durability of a cement-based
product. It can also provide a tough, durable gray textured or
stucco-like decorative finish. If desired, this product may be
integrally colored with a liquid cement or mortar colorant or
painted when fully cured to match existing home design.
Features and Benefits
• Easy brush-on or troweled application
• Polymer-modified for improved adhesion
• Durable cement finish coating
• Just mix with water and use
When/Where to Use
• Interior or exterior applications
• Protects exposed insulation board from damage to: UV rays
or weathering and general wear or impact
• Create textured finish coat of insulation
• Use above or below grade
