SEALTIGHT® SAFE-SEAL 3405

HIGH PERFORMANCE, COLD-APPLIED, ONE-COMPONENT, HORIZONTAL CRACK AND JOINT SEALER

DESCRIPTION
SEALTIGHT 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. At 75ºF and 50% humidity, a typical joint of 1/2" x 1/2" becomes tack free in two hours or less. After fully cured, the product will remain flexible at cold temperatures and will not flow at high temperatures. SAFE-SEAL 3405 is the only asphaltic-based, one-part, cold-applied sealer to meet the demanding performance characteristics of ASTM D 3405.

FEATURES / BENEFITS

• Meets ASTM D 3405 – High performance characteristics
• No hot kettle required – Safe to use…no danger of burns
• No expensive equipment needed – No equipment maintenance, breakdowns, fires, etc.
• Use smaller, non-specialized crews – Reduced installation costs
• Can be applied to damp cracks – Saves time…no need for joints to fully dry
• Develops a "skin" quickly – Will take traffic within two hours
• Pours directly from container – Easy to apply
• VOC-compliant –Environmentally safe
• User-friendly – Easy to clean-up

SPECIFICATIONS (Meets or Exceeds Performance Characteristics)

• ASTM D 3405
• ASTM D 1190
• AASHTO M 301
• AASHTO M 173
• Fed. Spec. SS-S-1401C
• Fed. Spec. SS-S-164

USES
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 sealer for either concrete or asphalt pavement repairs…will remain pliable, will not become brittle and crack in cold weather, or track in warm weather.

APPLICATION
SURFACE PREPARATION: The joints and cracks to be sealed must be clean. 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 should be routed out to provide a sealant reservoir 1/2" (12.7mm) wide with a minimum depth of 1/2" (12.7mm). This provides for a 1:1 width-to-depth ratio.

Proper routing should be slightly larger than existing crack/joint to ensure proper adhesion to sidewalls. 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 squeege 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 KOOL-ROD 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 minimum 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 KOOL-ROD Backer Rod may be installed in the joint opening to control depth and sealant usage.
