SAFE-SEAL® 3405

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

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. 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 asphalt-based, one-part, cold-applied sealer to meet the demanding performance characteristics of ASTM D 3405 and ASTM D 6690, Types I, II and III.

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)

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. This material remains pliable, 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" (12.7mm) wide with a minimum depth of 1/2" (12.7mm). 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" (9.54mm) wide with a minimum 1/2" (12.7mm) 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 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.

PRECAUTIONS
KEEP FROM FREEZING. Storage temperature should not exceed 90ºF (32ºC). Do not apply SAFE-SEAL 3405 if rainfall is forecast or imminent within 24 hours.
