COLD-APPLIED RUBBERIZED-ASPHALT SEALER
Single-component, cold-applied joint
sealant makes short work of sealing contraction and dummy joints.
SEALTIGHT #158 Cold-Applied Rubberized-Asphalt Sealer is a ready-to-use,
gun-grade joint sealer developed for use in sealing all contraction and dummy
joints in pavement, curb and gutter sections.
SEALTIGHT #158 Cold-Applied Rubberized-Asphalt Sealer is a
single-component, cold-applied rubber-asphalt joint sealing compound. It is
applied under pressure through an extruding nozzle or from a caulking gun, for
complete joint filling.
SEALTIGHT #158 Cold-Applied Rubberized-Asphalt Sealer was developed
for use in sealing horizontal contraction and dummy joints in pavements and
curbs and gutters to prevent the penetration of water and incompressibles into
the joint. For use in sealing deep joints up to 1/4" (6.35mm) in width, or
shallow joints with a 1/2" (12.7mm) depth maximum. To control joint depth
and sealant usage, SEALTIGHT KOOL-ROD Backer Rod may be inserted into the joint

SURFACE PREPARATION: Joint to be sealed
with SEALTIGHT #158 must be cleaned of all dust, dirt, laitance or any foreign
material and be dry. When resealing old joints, all sealing material must be
removed and the joint interfaces cleaned by sandblasting or mechanical abrading.
All joints should be cleaned with compressed air just prior to the sealant
METHOD OF APPLICATION: SEALTIGHT #158 is ready-to-use direct from the container.
A professional bulk caulking gun can be used for smaller joint sealing
operations. In larger installations, use a heavy-duty, 20:1 ratio flange bulldog
pump with follower plate and extension nozzle. For best results, fill the joint
from the bottom to 1/8" (3.18mm) below the pavement surface. Avoid bridging
or leaving air pockets in the sealant.
Pavement and air temperature should be 40ºF (4ºC) or higher for application of
#158. In cold weather, store in a heated warehouse to reduce viscosity for ease
