DESCRIPTION
SAFE-SEAL 3405 is a high performance,
polymer-modified, asphalt emulsion horizontal
joint and crack sealant. It is a one-component,
self-leveling material that can easily
be poured into openings 1/8” up to 1” wide.
After full cure, the product will remain
flexible at cold temperatures and will not flow at
high temperatures.
USES
SAFE-SEAL 3405 is ideal for small-, medium-,
or large-scale sealing projects on parking lots,
highways, street maintenance, driveways, and
airport aprons and runways. SAFE-SEAL 3405
should be used in any application where superior
performance is a necessity or where a hot-applied
product is either too dangerous or impractical. It
offers excellent bonding properties, high
resiliency, and resistance to weathering. It
provides a soft, flexible sealer for either concrete
or asphalt pavement repairs. This material
remains pliable and will not track in warm
weather or become brittle and crack in cold
weather.

Surface and Joint Preparation...The joints and cracks to be sealed must be clean. Dust, dirt, and laitance should be removed prior to application. Proper routing should be slightly larger than existing crack/joint to ensure proper adhesion to sidewalls.
Asphalt 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” (12.7 mm) wide with a minimum depth of 1/2” (12.7 mm). This provides for a 1:1 width-to-depth ratio. To control and maintain the suggested joint depth and sealant usage, KOOL-ROD backer rod may be installed in the joint opening.
New Concrete Pavement Sealing … Designated joint width and depth is determined by the appropriate highway or pavement authority. Typical joint configuration should be 3/8” (9.54 mm) wide with a minimum 1/2” (12.7 mm) depth for an approximate 1:1 width-to-depth ratio. KOOL-ROD backer rod may be installed in the joint opening to control depth and sealant usage.
Application Method … SAFE-SEAL 3405 should be applied into the crack/joint, slightly overfilling. SAFE-SEAL 3405 may be poured from the container or a commercial sealing pot equipped with a narrow pouring spout and shutoff valve. Once applied, a follow-up should be done with a soft, rubber, U-shaped squeegee to form a wipe zone of approximately 3-4” (76.2 – 101.6 mm) wide along the crack/joint and flush with the highway or pavement surface.

PRECAUTIONS
KEEP FROM FREEZING. Storage temperature
should not exceed 90° F (32° C). Do not apply
SAFE-SEAL 3405 if rainfall is forecast or
imminent within 24 hours. Do not apply SAFE-SEAL
3405 when air, material, and surface
temperatures are expected to fall below 50° F
(10° C) within eight hours of completed
application. SAFE-SEAL 3405 is not
recommended for sealing cracks or joints in
tennis courts Refer to Material Safety Data Sheet
for complete health and safety information.
