POLYMERIC HOT-APPLIED SEALANT
Provides an economical, hot-applied joint
sealant for large-scale joint and crack sealing operations.
SEALTIGHT #164 Polymeric Hot-Applied Sealant is ideal for
large concrete pavement, bridge, runway and taxiway maintenance crack and joint
SEALTIGHT #164 Polymeric Sealant is a time-proven, hot-applied
polymeric sealant which combines a tenacious adhesive power with high
resiliency. #164 provides a positive seal during expansion and contraction of
the joint and it will not lose bond in cold weather or flow in hot weather.
#164 is ideal for the large-scale sealing of transverse and
longitudinal joints in Portland Cement concrete pavements and joints in bridges,
airport runways, taxiways, etc. It is also used for the maintenance sealing of
cracks and joints in concrete and asphaltic concrete pavements, parking lots,
Advantages and Benefits
|Provides an economical solution for large-scale,
hot-applied joint and crack sealing applications
|Combines tenacious bonding power with high resiliency
|Maintains a positive seal during expansion and
|Will not lose bond in cold weather or flow in hot
|Works equally well in Portland Cement or asphaltic
Melter-Applicator with Applicator Wand
MELTING: #164 must be melted in a
double-boiler, oil-jacketed melter-applicator equipped with an agitator and
separate temperature controls for both the oil bath and melting vat. Add small
quantities of #164 with plastic liner to the melter and, while under continuous
agitation, add additional material as needed.
CONTROL MATERIAL TEMPERATURE AT 370ºF (188ºC). NEVER EXCEED 390ºF (199ºC).
RECOMMENDED POURING TEMPERATURE IS 370ºF (188ºC).
Material may be added to the melter as the sealant is withdrawn during the
SURFACE PREPARATION: The joints and cracks to be sealed must be clean and dry.
Dust, dirt and laitance should be removed prior to application.
ASPHALTIC PAVEMENT and MAINTENANCE SEALING: For ideal sealing, with maximum
effectiveness, it is suggested that cracks or joints should be routed out to
provide a sealant reservoir 1/2" (12.7mm) wide with a minimum depth of
1/2" (12.7mm). This provides for a 1:1 width-to-depth ratio. For joints
1" (25.4mm) wide, the suggested depth is 1/2" (12.7mm) minimum.
Proper routing should be slightly larger than existing
crack/joint to ensure proper adhesion to sidewalls. The sealant should be
applied into the crack/joint from the bottom up, slightly overfilling. Once
applied, a follow-up should be done with a soft rubber, U-shaped squeege 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. To control and
maintain the suggested joint depth and sealant usage, SEALTIGHT CERA-ROD
Heat-Resistant Backer Rod may be installed in the joint opening.
NEW CONCRETE PAVEMENT SEALING: Typical joint configuration should be 3/8"
(9.54mm) wide with a minimum 1/2" (12.7mm) depth for an approximate 1:1
width-to-depth ratio. Designated joint width and depth is determined by the
appropriate highway or pavement authority. SEALTIGHT CERA-ROD Heat-Resistant
Backer Rod may be installed in the joint opening to control depth and sealant
SEALANT APPLICATION: Seal with SEALTIGHT #164, when the air and pavement
temperatures are 40ºF (4ºC) or higher. At the end of each day's sealing
operation, all material remaining in the lines should be drawn off. Small
quantities of unused material remaining in the melter may be remelted and used
the following day.
69.8 Ibs./ft³ (1,120 kg/m³). A 1/2" x 1/2" (12.7mm x 12.7mm)
joint will require 12.2 Ibs./100 linear feet (18.2 kg/100m).
DO NOT DILUTE. #164 is not resistant to jet fuels and is not
recommended for swimming pools or joints subjected to hydrostatic pressure. #164
must not be heated above the recommended 390ºF (199ºC) or the rubber polymers
will decompose, resulting in unsatisfactory performance. Refer to Material
Safety Data Sheet for complete Health and Safety Information.
