asphalt sealant in bag

bitumen sealant in 25Kg bag box drum

asphalt sealant

bitumen sealant characters:

    • Able to fill cracks up to 1.5 in. wide
    • Easy application, self-levels
    • Fast tack-free time (less than 1 hr)
    • Resists aging and weathering
    • Excellent adhesion, bonds to asphalt and concrete

This durable and flexible sealant is great for filling cracks in asphalt driveways, parking lots, roadways, aprons, and other asphaltic surfaces. It self levels, reducing the number of tools needed to complete your project and cures to a matte black finish to blend with existing asphalt.

Bitumen sealant uses

be used by experienced professionals as well as do-it-yourselfers. For joint sealing and crack repairs on: ▪ Asphalt driveways ▪ Asphalt roadways / walkways ▪ Asphalt pavements ▪ Asphalt to concrete joints ▪ Aprons, approaches, etc.

Advantage of bitumen sealant

▪ Single component, no mixing

▪ Self-leveling consistency

▪ Fast skin time (< 60 minutes)

▪ Permanently elastic

▪ High durability

▪ Resists aging, weathering

▪ Excellent adhesion

application before uses:

All joint surfaces must be clean, sound, free of contaminants, dust free, dry and frost free. Interior joint contact surfaces must be free of previous joint sealing materials, oils, grease, loose tar, paints, coatings, sealers, curing compound residues, rust and any other foreign matter that might prevent good adhesion. Asphalt should be prepared to clean, sound, dust free, dry, and frost free conditions. Concrete substrate preparation should be accomplished by mechanical means (e.g. sandblasting, abrasive grinding, etc.). Mask off and protect any adjacent surfaces (e.g. edges of joint) that should not receive contact with bitumen Sealant. Closed cell backer rod or bond breaker tape must be installed at the bottom or base of a dynamically working joint prior to sealant installation to prevent three sided adhesion. Closed cell backer rod diameter should be larger (i.e. typically up to 25% larger) than the actual width of the joint to provide a friction fit and adequate sealant support. Bond breaker tape, when used in lieu of closed cell backer rod, should cover the bottom or base of the joint void. Joint Design: Proper joint design for working joints is 2:1 width to depth ratio (typical), with a recommended minimum 1/4 inch (6 mm) and maximum 1/2 inch (13 mm) depth of bitumen sealant. For nonmoving joints, the width to depth ratio can vary. For traffic bearing joints, the maximum recommended 1/2 inch (13 mm) depth of thickness should be considered over appropriate closed cell backer rod or bond breaker tape. Consult with our technical rervices for unusual joint configurations.

Recommended application

temperatures: 50 to 100 °F (10 to 38 °C). Condition sealant cartridge to 65 to 75 °F (18 to 24 °C) before using. Cut the plastic tip at an angle to the desired size and puncture the airtight seal within, at the base of the tip. The maximum sealant depth is 1/2 in. (13 mm) and width is 1 inch (25 mm). The minimum sealant depth is 1/4 in. (6 mm) and width is 1/4 in. (6 mm). Dispense sealant into the joint slot over either closed cell backer rod or bond breaker tape in one direction and allow the sealant to flow and level out as necessary. Tool as required, although minimum
