CRACK RITE PL 500
HOT POUR DIRECT FIRE JOINT SEALANT
Description: CRACK RITE PL 500 is a high quality joint and crack sealant
designed for asphalt and cement pavements. PL 500 designed to be an effective
and economical method to extend the life of asphalt or cement pavements. PL
500 will prevent water penetration which will protect from pavement degradation,
potholes and eventual failure. PL 500 is formulated with polymer rubbers,
stabilizers, plasticizers, filler and asphaltic resins. PL 500 is hot applied and is a
one part material that will stand the test of time in cold weather and freeze thaw
cycles. PL 500 sets up quickly for high traffic parking lots, resists ‘softening’ in
warm weather climates but will remain flexible in cold weather climates
Recommended Uses: PL 500 is recommended for sealing joints and cracks on
parking lot, highway, street, airport taxi ways and driveways (blacktop or
concrete.) PL 500 is relatively hard and has a high softening point which makes it
suitable for parking lot application. It is designed to seal expansion joints,
longitudinal and transverse cracks, joints between asphalt and concrete … and
random cracks.
Surface Preparation: In order to ensure adhesion and achieve maximum
performance it is important to properly prepare the surface. The joint or crack
must be free of moisture, dirt, dust and loose aggregate. The pavement surface
and outdoor temperature must be 40° F or above. To clean out the crack or joint
properly we recommend air blowing, routing or sandblasting. Use oil-free
compressed air and heat to clean and dry the joint immediately prior to sealing.
Joints/Cracks should be sized so that the maximum adhesion and compression
do no exceed 50% of the width. Best results are obtained when the joints or
cracks are opened at least ½” in width.
Melting and Application: Note: ALWAYS wear eye protection, gloves and
long sleeve clothes and pants when using PL 500. The melting kettle can be
a conventional oil jacketed unit or a direct fire kettle with mechanical agitation
and temperature control devices. Carefully insert small quantities (PL 500 comes
in 25 lb. blocks) of PL 500 and the plastic bag into the melting equipment while
the agitator is turned OFF. Load the material in SLOWLY to avoid splashing.
After the initial load has reached the recommended pouring temperature, fresh
material may be added to the melter as the sealant is used. Melt only the material
that will be used during the day. Purge material remaining in the kettle lines at the
end of each sealing operation. The material may be safely reheated and can be
applied using a pressure feed wand system or a pour pot.
Note: The temperature of the heat transfer oil should not exceed 535°F. Do not
heat PL 500 above the maximum heating temperature and do not maintain it at
that temperature for prolonged periods of time. This could cause the material to
gel in the equipment or fail in the joints/cracks. A significant viscosity increase
accompanied by stringiness signals the approach of gelation. If this occurs,
immediately remove the material from the melter and dispose of it.
