CRACK-RESISTANT SURFACE BONDING CEMENT
Page 2
Bonding Dry-Stack Segmental Retaining Walls & Masonry
Walls:
• Footings or Foundations: The secret to sound structure is
a strong, level foundation. A level and properly aligned
footing makes stacking and troweling much easier. Footings
must be built below the frost line and should a be a minimum
of twice the thickness of the blocks used. Consult your local
masonry supplier for information about footings and slab
construction.
• Dry-stacking Masonry Units: Lay the first course of
masonry units in a full bed of Crack-Resistant Surface
Bonding Cement. Make sure this course is straight and level.
Dry-stack masonry units in a staggered or running bond
pattern for strength. As you place masonry units in position,
slide it against the masonry units below to smooth out any
roughness. Crack-Resistant Surface Bonding Cement can be
used between masonry units to maintain a level and properly
aligned wall. The better you are in maintaining a level and
aligned wall, the stronger and more attractive your finished
wall will be. Dry-stack the rest of the wall before applying the
Crack-Resistant Surface Bonding Cement to both sides of
the wall. Apply product with a trowel in upward strokes,
maintaining a uniform thickness of at least ⅛ in. (3 mm). Do
not over-trowel.
Curing
Like other cement based materials, Crack-Resistant Surface
Bonding Cement gets most of its strength within 24 hours after
application. It is imperative to keep the new surface area damp
for at least 2 days. Wetting the walls once or twice daily with a
fine mist will ensure proper curing for strength. Hot, windy or
dry conditions may require more frequent wetting. Wet curing
may be minimized when using Concrete Bonding Additive.
Finished surface can be painted with most paints once cured
for a minimum of 7 days and area remains dry.
Clean Up
Use soapy water to clean hands and tools immediately after
use. Dried material must be mechanically removed. Use a
waste water hardener (e.g. Congelz
®
or similar product) for
cementitious waste disposal.
Limitations
• Follow all industry standard safety procedures when
handling, such as gloves and eye protection. Wear gloves at
all times, failure to do so can result in severe burns.
• Mix with clean potable water or a liquid bonding additive.
• Do not use more than the recommended amount of liquid.
Overwatering may cause excessive shrinkage, cracking,
reduce adhesion, and long term durability.
• When applying over previously coated and non-porous
surfaces it is recommended to use a dilution of 2 parts Akona
Concrete Bonding Additive and to 1 part water. For extra
difficult restoration and waterproofing projects, Akona
Concrete Bonding Additive is recommended to be used full
strength in place of water.
• Apply between ⅛ in. (3 mm) up to ½ in. (13 mm) thickness.
• When additional layers are needed to build-up product, apply
second coat after initial set of first coat, while product is still
partially damp and plastic (approximately 2-4 hours) and
dampen the surface area between applications.
• Temperature and humidity may cause the set time to vary
slightly. Cooler weather will slightly retard set time – hot
weather will slightly accelerate set time.
• Do not apply over concrete cured less than 7 days, or is
frozen or contains frost.
