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 3.2 mm up to 25.4 mm (1/8” up to 1″) wide. At 24° C (75° F) and 50% humidity, a typical joint of 12.7 mm x 12.7 mm (1/2” x 1/2”) becomes tack-free in two hours or less. After full cure, the product will remain flexible at cold temperatures and will not flow at high temperatures.

SAFE-SEAL® 3405
High Performance, Cold-Applied, One-Component, Horizontal Crack and Joint Sealant
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 3.2 mm up to 25.4 mm (1/8″ up to 1″) wide. At 24° C (75° F) and 50% humidity, a typical joint of 12.7 mm x 12.7 mm (1/2″ x 1/2″) becomes tack-free in two hours or less. After full cure, the product will remain flexible at cold temperatures and will not flow at high temperatures.

USE
SAFE-SEAL 3405 is ideal for small-, medium-, or large-scale sealing projects on parking lots, highways, street maintenance, driveways, 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. SAFE-SEAL 3405 may be used wherever the measurable ASTM D 3405 specification is required. It provides a soft, flexible sealant 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 12.7 mm (1/2″) wide with a minimum depth of 12.7 mm (1/2″). This provides for a 1:1 width-to-depth ratio. To control and maintain the suggested joint depth and sealant usage, CERA-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 would be 9.54 mm (3/8″) wide with a minimum 12.7 mm (1/2″) depth for an approximate 1:1 width-to-depth ratio. CERA-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 shut-off valve. Once applied, a follow-up should be done with a soft, rubber, U-shaped squeegee to form a wipe zone of approximately 76.2 – 101.6 mm (3″ – 4″) wide along the crack/joint and flush with the highway or pavement surface.
