1. Bondbreakers
AVOIDING PROBLEMS

2. Definition DEFINITION
A bondbreaker is a material used to prevent adhesion of newly placed concrete and substrate

3. This will Cause Panels to Stick
Most Common Causes of Bondbreaker Problems
Improper Cure of Slab
Improper Finish on Slab
Insufficient Application of Bondbreaker
Uneven Application of Bondbreaker
Rain on Bondbreaker prior to drying
Not allowing Bondbreaker to completely dry
Hot Weather practices not followed
Improper Mixing
This will Cause Panels to Stick

4. Proper Cure of Slab THIS IS ESSENTIAL:
SLAB MUST BE CURED IMMEDIATELY AFTER FINISHING
USE AN ASTM C-309 CURING COMPOUND SUCH AS AN ACRYLIC
OR BONDBREAKER AS A CURE

5. Curing of Slab – Option #1
ACRYLIC or RESIN-BASED CURING COMPOUND
MEETS ASTM C-309
APPLICATION RATE 200 SQ FT/GALLON

6. Curing of Slab – Option #2
USE BONDBREAKER AS CURE COAT
APPLY EVENLY AT 200 SQ FT/GAL

7. Mixing Water-Based Bondbreaker
EACH DRUM HAS A INTREGAL MIXER
EACH DRUM HAS A MIXING HANDLE PROVIDED
USE SUPPLIED MIXER ONLY
DRUM MUST BE IN STANDING POSITION
MIX FOR MINIMUM OF 3 MINUTES
MIX BEFORE EACH USE (24 HR PERIOD)
ROLLING DRUM IS NOT PROPER MIXING

8. Coverage Rates ALWAYS FOLLOW RECOMMENDED APPLICATION COVERAGE RATES
CURE COAT SQ.FT/gallon
1st bond breaker coat = 400 SQ.FT/GAL
2nd or additional bond breaker coat = SQ.FT/GAL – Applied at right angles

9. Coverage Rates
POROUS OR ROUGH CONCRETE WILL REQUIRE ADDITIONAL BONDBREAKER
BONDBREAKER RAINED ON PRIOR TO DRYING WILL REQUIRE AN ADDITIONAL COAT.

10. Tests PRESENCE OF BONDBREAKER CAN BE CHECKED
SOAPY FEEL TEST: VERIFIES PRESENCE OR BONDBREAKER, BUT NOT NECESSARILY SUFFICIENT COVERAGE
WATER BEAD TEST: WATER THAT READILY BEADS ON THE SURFACE USUALLY INDICATES THE SUFFICIENT PRESENCE OF BONDBREAKER

11. Hot Weather Practices HOT WEATHER REQUIRES SPECIAL ATTENTION:
HOT WEATHER AIR TEMP > 90o F OR SLAB TEMP > 130oF
FLOOD SLAB TO SSD PRIOR TO APPLICATION OF BONDBREAKER... REMOVE EXCESS WATER.

12. Weather Considerations
RAIN
RE-COAT IF NECESSARY
HOT / WINDY
INCREASE APPLICATION RATE
COMMENCE CURING IMMEDIATELY
FOG SLAB TO SSD PRIOR TO APPLICATION OF BONDBREAKER
COOL AND DAMP
MAY INCREASE DRYING TIME
MORE LIGHT COATS
ALLOW EACH COAT TO DRY THOROUGHLY

13. Summary
BONDBREAKERS ARE OFTEN BLAMED FOR PROBLEMS RESULTING FROM POOR PROCESS
ALWAYS FOLLOW RECOMMENDED APPLICATION INSTRUCTIONS
BE AWARE OF WEATHER CONDITIONS
ALLOW EACH COAT TO DRY THOROUGHLY
TEST FOR PRESENSE OF BONDBREAKER
MISUSE OF BONDBREAKER REQUIRES EXPENSIVE REMEDIES
PROPER USE OF BONDBREAKER IS THE MOST CRITICAL PHASE OF TILT CONSTRUCTION

14. THE COST OF BONDBREAKER IS LOW COMPARED TO THE COST OF ONE STUCK PANEL
Remember
THE COST OF BONDBREAKER IS LOW COMPARED TO THE COST OF ONE STUCK PANEL
