DESCRIPTION
1190 is a hot-applied,
single-component polymeric compound developed for the economical
maintenance sealing of cracks and joints in Portland cement and
asphalt concrete. It offers excellent cohesive and adhesive qualities
- it will not lose bond in cold weather or flow in hot weather.
Ideal for large-scale sealing projects. Equally effective for
medium-to-small-scale projects.

PACKAGING
55 pound (24.95 kg) cartons
containing two 27.5 pound (12.47 kg) blocks individually wrapped
in poly bag liners.
APPLICATION
Melting…1190 should be melted in an oil-jacketed melter-applicator
with an agitator and separate temperature thermometers for oil
bath and melting vat.
Surface Preparation...The joints and cracks to be sealed must be clean and dry. Dust, dirt and laitance should be removed prior to application. Proper routing should be slightly larger than the existing crack/joint to ensure proper adhesion to sidewalls.
NOTE: Application of sealant into frozen or wet pavement will result in loss of bond and premature failure of the sealant.
New Concrete Pavement Sealing - Typical joint configuration should be 3/8"
(9.54 mm) wide with a 1/2" (12.7 mm) depth for an approximate
1:1 width to depth ratio. Designated joint width and depth is
determined by the appropriate highway or pavement authority. CERA-ROD® Heat-Resistant
Backer Rod from W. R. MEADOWS may be installed in the joint opening
to control depth and sealant usage.
Asphalt Pavement and Maintenance Sealing - For ideal sealing
with maximum effectiveness, it is suggested that cracks or joints
be routed out to provide a sealant reservoir 1/2" (12.7 mm)
wide with a minimum depth of 1/2" (12.7 mm). This provides
for a 1:1 width-to-depth ratio. For joints 1" (25.4 mm) wide,
the suggested depth is 1/2" (12.7 mm) minimum. To control
and maintain the suggested joint depth and sealant usage, CERA-ROD
Heat-Resistant Backer Rod from W. R. MEADOWS may be installed
in the joint opening.
Application Method...Sealing may be done at air temperatures of 40ºF (4ºC) and higher. The sealant should be applied into the crack/joint, slightly overfilling. Once applied, a follow-up should be done with a soft, rubber, U-shaped squeegee to form a wipe zone of approximately 3-4 inches (76-2 - 101.6mm) wide along the crack/joint and flush with the highway or pavement surface.
PRECAUTIONS
Application life may be
extended by adding fresh material as sealant is applied and the
quantity in the kettle decreases. 1190 hot-pour joint sealant
can be reheated once, within the prescribed safe heating temperature
limits. Repeated reheating may result in material degradation
or gelling in the melter. When the application life has been exceeded,
1190 will thicken, become stringy and may gel. If this occurs,
remove the sealant immediately from the kettle and discard.
Read and follow application information and use in accordance with the health and safety information shown on the label. Refer to Material Safety Data Sheet for complete health and safety information.
