COLD-APPLIED LOW-MODULUS HORIZONTAL JOINT
Provides a proven, cost-effective
alternative to hot-applied sealants.
SEALTIGHT SOF-SEAL Cold-Applied Low-Modulus Horizontal Joint Sealant is a
premium-quality, cold-applied, two-component, polymeric, pourable sealant
developed as a versatile, easy-to-apply, cost-effective method for preventative
maintenance service on all types of crack and joint sealing projects.
SEALTIGHT Cold-Applied SOF-SEAL Low-Modulus Horizontal Joint
Sealant is a premium-grade, pourable, two-component, horizontal sealant composed
of a special combination of polymeric compounds, that provides outstanding
performance in both Portland Cement and asphaltic concrete. Once properly mixed
and applied, it cures to a soft, highly-flexible, rubber-like material that is
capable of maintaining a sealed joint or crack over a wide temperature range.
Cold-Applied SOF-SEAL does not track in the summer and will not become brittle
at temperatures as low as -20ºF (-29ºC). It remains soft, flexible and pliable
in the joint, even after repeated freeze/thaw cycles. Cold-Applied SOF-SEAL
offers excellent elongation, high resiliency, tenacious bonding power and
excellent longevity. This self-leveling sealant requires no special application
equipment and can easily be poured into cracks and joints.
Cold-Applied SOF-SEAL is a versatile pavement sealant suitable for
both large or small-scale sealing. It is excellent for crack repair and
preventative maintenance sealing projects. It is ideal for use when a
maintenance group doesn't have a melter, or where it is not practical to fire-up
and repeatedly move melter-applicator units (small-scale sealing projects).
Typical applications include the sealing of expansion and contraction joints,
longitudinal joints and random cracks in concrete pavements, reflective and
random cracks in asphaltic paving and asphaltic-to-concrete shoulder joints.
It's ideal for high-sheer bridge joint applications. In addition, Cold-Applied
SOF-SEAL can be used as a pitch pan sealer.

JOINT SIZES...Cold-Applied SOF-SEAL
should be used in joints not less than 1/4" (6.35mm) wide. A 2:1
width-to-depth ratio should be maintained. However, in no case should joint
sealant depth be less than 1/4" or exceed 1/2". Proper joint design
practices and application techniques must be followed for successful
JOINT PREPARATION...Remove foreign substances, incompressibles and free water
from joint opening. For proper adhesion, joints must be clean and dry. Dust,
dirt and laitance should be removed prior to application. SOF-SEAL adheres well
to unprimed concrete; however, the use of P/G Primer is recommended for optimum
adhesion. To control sealant depth, insert SEALTIGHT KOOL-ROD™ Backer Rod or
in the joint before sealing. For larger joints, where additional support is
required, use a non-asphaltic joint filler such as CERAMR Flexible Foam
Expansion Joint Filler (Refer to Data Sheet No. 323). For straight joint edges,
mask off top surfaces with masking tape.
MlXING: The 2 components of Cold-Applied SOF-SEAL are
pre-measured and must be mixed together at 1 time. Add Part A, the activator, to
Part B and mix to blend thoroughly. Mixing can be accomplished by hand (see B)
or with a variable speed drill operated at slow speeds (see A). In either case,
the mixing should be interrupted occasionally and the mixing paddle used to wipe
material from the sides and bottom of the container for thorough blending.
A. PREFERRED METHOD: Mixing with a variable speed drill
fitted with a slotted, flat-headed paddle is best accomplished when the drill is
operated at slow speeds not to exceed 400 rpm. MIXING TIME IS 5 MINUTES MINIMUM.
B. Mixing by hand can be accomplished with a flat, wooden
mixing paddle. MIXING TIME BY HAND IS 8 MINUTES MINIMUM.
POURING: Cold-Applied SOF-SEAL may be poured from its original container or any
clean container suitable for pouring. A commercial sealing pot equipped with a
narrow pouring spout and shutoff valve is ideal. To facilitate prompt opening to
vehicular traffic, about 1 hour after applying sealer, dust with limestone dust
or talc, as an example, to minimize tracking. Clean up before material has
cured, with an aromatic solvent such as Toluene. After material has cured, it
will be necessary to cut or abrade the material from equipment.
Two-component, Cold-Applied SOF-SEAL is packaged in convenient 3 gallon (11.36
liter) Units. The base material is furnished in an oversized container suitable
for mixing and pouring. The activator is furnished in a bottle inserted in a
plastic bag which is wire-tied to the bale and hangs inside the container. Both
components are pre-measured to exact quantities. Mix all materials in container;
do not mix partial units.
7.47 gals./ft³ (1,000 liters/m³). A joint 1/2" X 1/2"
(12.7mm x 12.7mm) will require 1.3 gals./100 linear feet (16 liters/100m).
SOF-SEAL should be stored in a cool warehouse. Like many top-quality,
two-component sealants, SOF-SEAL has a limited (maximum 6 months) shelf life and
should be used as quickly as possible after purchase.
NOTE: Do not open pail until ready to use, as this significantly reduces shelf
Limitations / Precautions
Cold-Applied SOF-SEAL components are pre-measured to exact
quantities. Mix all materials in container; do not mix partial units or dilute.
SOF-SEAL is specifically formulated to remain soft and pliable in pavement
joints and cracks and is not suggested for application in plaza decks, shopping
malls and other areas subjected to mass pedestrian traffic, high heels, etc.
Prior to mixing, Cold-Applied SOF-SEAL should be stored at temperatures of 55ºF
(13ºC) or higher. Apply only when the temperatures of the air and joint
interfaces are 40ºF (4ºC) or higher. Do not use on wet joints.
Avoid contact with skin or prolonged breathing of vapors. Refer to Material
Safety Data Sheet for complete Health and Safety Information.
