SEALTIGHT®
1190
POLYMERIC COMPOUND
Description
SEALTIGHT 1190 is a hot-applied,
single-component polymeric compound developed for the economical maintenance
sealing of cracks and joints in Portland Cement and asphaltic concrete. It
offers excellent cohesive and adhesive qualities...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.

Use and Application
SEALTIGHT 1190 should be melted in an
oil-jacketed melter-applicator with an agitator and separate temperature
thermometers for oil bath and melting vat. Sealing may be done at air
temperatures of 40ºF (4ºC) and higher.
NOTE: Application of sealant into frozen or wet pavement will result in loss of
bond and premature failure of the sealant.
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 be routed out to provide a sealant resevoir 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 the existing crack/loint 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 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. 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 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 usage.
Packaging
55 pound (24.95 kg) cartons containing two 27.5 pound (12.47
kg) blocks individually wrapped in poly bag liners.
Precautions
Application life may be extended by adding fresh material as
sealant is applied and the quantity in the kettle decreases. SEALTIGHT 1190
hot-pour joint sealant can be reheated once within the prescribed safe heating
temperature limits. Repeated reheating may result in material degradation or
jelling in the melter. When the application life has been exceeded, SEALTIGHT
1190 will thicken, become stringy and may gel. If this occurs, remove the
sealant immediately from the kettle and discard.
Read and follow application informationand 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.
