KEEP OUT OF REACH OF CHILDREN
MIXING
1. Use cool, potable water, clean tools and
clean containers. For additional bond
strength to the substrate, use a
concrete bonding additive in place of
water.
2. Mix only the amount that can be applied
within the 10-20 minute working time.
3. Add approximately 1½ pints (.71 L) of
clean, cool water per 10 lbs. (4.5 kg) of
powder. (Ratio of approximately 2.4 oz.
liquid per 1 lb. powder.) Always add
powder to liquid to avoid lumps. Avoid
high-speed mechanical mixing which
can entrap air into the mixture. Smaller
amounts can be mixed by hand.
4. Mix to a uniform, lump-free, putty-like
consistency, approximately 2-3 minutes.
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.
6. For repairs over 1 in. (2.5 cm) thick, add
5 lbs. (2.26 kg) of 3/8” pea gravel per 10
lbs. of Instant Patching Cement. Apply
pea gravel blend up to 5 in. (127 mm)
per layer.
APPLICATION
1. Apply using a steel trowel to surfaces
that are frost free and above 40°F (4°C)
and below 90°F (32°C) within 24 hours
of application and 48 hours thereafter.
Do not apply in direct sunlight on hot,
windy days, or when rain is forecasted
within 6-8 hours.
2. To reduce shrinkage and cracking, build
up in layers of 1 in. (25 mm) neat, or 5
in. (127 mm) when extended. Additional
layers can be applied after 24 hours.
3. Clean the surface of the trowel often
with water and use a “light touch” when
finishing the surface. Do not over
trowel. If a textured finish is desired,
brush in one direction with a soft-
bristled brush or broom while patch is
still soft.
4. Protect the surface from use until patch
is completely hard and set. On average,
supports foot traffic in 5 hours, wheeled
traffic in 24 hours depending upon
humidity and temperatures.
Shelf Life Best when used within
one year in original,
unopened package.
Storage
Conditions
Store dry. Best to
condition material to 50-
80°F (10°-27°C) before
using.
Color Gray
CURING
After the patch has reached final set,
during the first 24 hours, keep the patch
damp or covered to prevent excessive
loss of water, especially during hot and/or
drying winds or when low humidity are
present. Under such conditions, damp
cure by covering the surface with wet
burlap or towel overnight to retain
moisture or lightly fog spray. After 24
hours, remove covering and allow to air
cure. Damp curing is not required when
used to repair smaller cracks.
Repair can be painted with a latex
masonry paint once cured a minimum of 7
days and area remains dry.
CLEAN UP
Typically water will satisfactorily clean
tools immediately after using this product.
If the material has begun to harden, warm
soapy water may be helpful for cleaning
hands and tools. Dried material requires
mechanical removal.
IMPORTANT NOTES
WEAR GLOVES AT ALL TIMES,
FAILURE TO DO SO CAN RESULT IN
SEVERE BURNS.
Goggles are recommended eye
protection safety equipment.
Do not add any materials other than
clean potable water.
Do not use more than the
recommended amount of water.
Overwatering may cause excessive
shrinkage and cracking.
Use only clean mixing containers and
tools.
Do not cover or fill expansion or control
joints.
Do not apply over concrete cured less
than 28 days, or that is frozen or
contains frost.
Proper application and installation of all
AKONA products are the responsibility of
the end user.
