FEATHER EDGE PRO
Fast-setting, non-sanded, patch & skim coat
© TCC Materials
®
• October 2017 Version 2.0
A mechanical mixer such as a paddle and
a ½ in. heavy-duty drill will result in a
better consistency and save time. Smaller
batch quantities should be mixed by hand.
Note: Elevated temperatures will shorten
the working time. Lower temperatures will
delay set times.
APPLICATION
Apply only to surfaces that are frost free
and between 50°F-80°F (10°C-27°C) for
24 hours prior to application and 48 hours
thereafter.
REGULAR APPLICATIONS
1. Apply Feather Edge Pro with a steel
trowel onto properly prepared surface
using enough pressure to fill all defects
and prepare the subfloor to the desired
finish.
2. Do not exceed thickness of ½ in. (13
mm) per lift.
3. Begin to finish immediately using a flat
steel trowel.
4. Flooring can be applied in as little as 30
minutes or as soon as completely dried.
5. For a smoother finish, Feather Edge
Pro can be sanded once cured (usually
within 1 hour under normal conditions).
6. This product should not be over-
troweled or over-worked. Clean tools
often.
7. For applications to areas greater than 4
sq. ft. (1 m
2
) where the uniform
thickness is >½ in. (>13 mm), use a self
-leveling underlayment, such as Akona
Self-Leveling Floor Underlayment
Cement.
8. If a higher build-up is needed, allow a
minimum 1 hour curing time between
multiple lift applications.
WHEN USED WITH FLOORING
INSTALLATION
• Feather Edge Pro will accept standard
floor coverings such as VCT, vinyl sheet
goods, tile, and carpeting in
approximately 15-30 minutes after
placement.
• When using moisture sensitive
adhesives such as urethanes and
epoxies, employed with wood floors
etc., Feather Edge Pro may necessitate
16 hours of curing.
• Feather Edge Pro is a cement-based
product therefore all adhesives
compatible with concrete should be
acceptable. Consult adhesive
manufacturer.
• Always install a test area, insuring
suitability of Feather Edge Pro for
intended use.
interfere with bond strength.
• For difficult substrates such as existing
adhesive residue, we recommend
mixing with 100% Akona Concrete
Bonding Additive in lieu of water to
increase bond and flexural strength
(Refer to mixing instructions). The
addition of a latex additive will extend
the setting time.
PREPARATION OVER EXISTING
OTHER SURFACES
• Marble, terrazzo and existing ceramic
tile surfaces must be well bonded to
subfloor, cleaned of any waxes and
abraded to a rough surface prior to
application of Feather Edge Pro.
• For difficult substrates such as marble,
terrazzo, sealed gypsum, and existing
tile surfaces, we recommend mixing
with 10% Akona Concrete Bonding
Additive in lieu of water to increase
bond and flexural strength (Refer to
mixing instructions). The addition of a
latex additive will extend the setting
time.
• When applying over gypsum that has
not been properly sealed, prime
gypsum surface twice with Akona
Concrete Bonding Additive. The first
coat uses Concrete Bonding Additive
diluted 3:1 with clean water; the second
coat uses Concrete Bonding Additive
diluted 1:1 with clean water. Allow
sealer to dry between coats and before
application of Feather Edge Pro.
MIXING
1. Use cool, potable water, clean tools and
clean containers.
2. Dry-blend Feather Edge Pro powder
prior to mixing.
3. Mix only the amount that can be applied
in 15-20 minutes.
4. Always add the powder to the liquid and
mix with a low speed drill (300 RPM or
less) until a lump-free mix is obtained.
Use a mixing paddle that does not
entrap air into the mortar.
5. The amount of water can be modified
for various applications and set times.
For each 10 lb. (4.5 kg) pail of powder,
mix approximately 2-2½ qt. (1.9-2.3 L)
liquid. For smaller batches, use 1 part
water to 2 parts powder.
6. When going over cutback, adhesive,
ceramic tile, or as an embossing
leveler, substitute all of the water with
Akona Concrete Bonding Additive.
7. Mix thoroughly to a lump-free,
trowelable consistency.
8. Retemper as pot life nears set time by
remixing, without additional water.
SKIM COAT APPLICATION
• Apply mixture using a smooth-edge
trowel to level the surface area by
forcing the mix into substrate defects,
voids and gaps.
• Trowel at a 45 degree angle to the
substrate surface to fill voids while
removing excess material from the
surface.
EMBOSSING APPLICATION
• All material to be embossed must be
clean and free of any waxes or other
finishes.
• The flooring must be well bonded and
not show any signs of moisture, mildew,
or other deterioration.
• For embossing applications use Akona
Concrete Bonding Additive in lieu of
potable water. (See mixing instructions.)
• Typical drying time would be 1½ hours
prior to using flooring adhesive.
• Do not use Feather Edge Pro for
embossing cushion backed flooring or
perimeter bonded flooring.

CURING
• Feather Edge Pro is self-curing,
however protect from excess heat, rapid
air movement, and direct sunlight.
• The use of damp curing or the use of
curing compounds is not recommended
CLEAN UP
Typically warm, soapy water will
satisfactorily clean tools while product is
wet, dried product is insoluble in water.
Clean tools and spills before it dries, as
hardened
Proper application and installation of all
Rapid Patch products are the
responsibility of the end user.
