TERRAZZCO® Bonding Agent 159 is a 100% solid (VOC free) epoxy resin system designed to promote adhesion between a concrete slab and the terrazzo mix.
Bonding Agent 159 promotes the longevity of a terrazzo while controlling potential cracking during the flooring life-cycle.
TERRAZZCO® Bonding Agent 159 is ideal for industrial, commercial, retail, healthcare and institutional facilities.
This epoxy resin product creates an effective bond between the concrete slab and the terrazzo topping.
Working (Pot) Life: 50 minutes @ 75°F
Full Set Time: 6-8 hours @ 75°F
Full Cure Time: 7 days @ 75°F
TERRAZZCO Bonding Agent 159 are pre-weighted and packaged so one container of Part A resin is mixed with one container of Part B hardener.
A thickness of 6 mils (300-350 sq. ft. per unit). Coverage will vary depending on surface profile and porosity.
1. Premix TERRAZZCO® Bonding Agent 159 resin part A using a low-speed drill and jiffy blade for two to three minutes
2. Add one part TERRAZZCO® Bonding Agent 159 resin part A to one part TERRAZZCO® Bonding Agent 159 hardener part B by volume. Mix using the drill and jiffy blade for two to three minutes
3. Pour the mixed material onto the working area and spread using a roller or squeegee to achieve a thickness of 6 mils (300-350 sq. ft. per unit). All areas should be uniformly coated. Coverage will vary depending on surface profile and porosity.
4. In case of small application areas (50-100 sqft), Bonding Agent can be immediately covered by terrazzo. If bigger areas are covered, priming will be a separate step – in which case fine aggregate broadcasting will be required, after which the Bonding Agent full set time will be 6-8 hours.
