• Semi-Self-Leveling Formula: Smooth application on horizontal and sloped surfaces (up to 6% grade).
• High Movement Capability: ±35% movement, modifiable to +100% / -50% with proper joint design.
• Excellent Adhesion: Bonds well to green and damp concrete with no outgassing.
• Durable: Resists wear in high-traffic areas and exposure to jet fuel.
• UV and Weather Resistant: Performs in outdoor and exposed conditions.
• Immersion Rated: Approved for use in non-chlorinated water (e.g., fountains, decks).
• Easy to Apply: Compatible with standard sausage or cartridge caulking guns.
• Certified & Compliant: Meets ASTM C920, CAN/CGSB 19.13-M87, and UL 2079 fire-resistance standards.

Typical Uses

• Expansion joints in sidewalks, plazas, and flatwork
• Swimming pool decks and outdoor patios
• Parking structures and pedestrian areas
• Sloped surfaces up to 6% grade (1" per 16')

Compatible Substrates

• Green, damp, or cured concrete
• Masonry and CMU
• Precast concrete panels
• Brick, stone, and stucco
• Metal (primed if necessary)
• Other porous and non-porous materials (with proper prep)

Surface Preparation

• Ensure substrate is clean, dry or damp (not wet), and structurally sound.
• Clean using the two-cloth method: wipe with xylene, then dry cloth.
• Use Vulkem® Primer #171 for porous substrates if testing recommends.
• Use TREMprime® Non-Porous Primer for metals and plastics if needed.

Joint Design

• Minimum joint: ¼" x ¼" (6 mm x 6 mm)
• Joints ½" to 1": depth should be ½ the width
• Maximum joint depth: ½" (13 mm)
• Use backer rod or bond breaker tape to avoid 3-point adhesion

Application

• Apply with standard sausage or cartridge gun (AWF PRO 18:1 recommended)
• Fill joint from back to front to prevent air entrapment
• Tool within 2 hours to create a concave, water-shedding profile
• Tool dry — do not use soap, water, or solvents

Curing

• Sealant must remain undisturbed during curing process
• Cure rate depends on humidity and temperature
• Full adhesion may take up to 2+ weeks
