How many coats are recommended for bond breakers?

• A. Minimum of 2
• B. One
• C. Three
• D. Four

Answer: (A)

Bond breakers create a release layer so the concrete doesn’t stick to the formwork. Because concrete is porous and forms can have irregularities, a single layer can have pinholes or thin spots that let the concrete bond during stripping. Applying at least two coats helps ensure complete, uniform coverage and a thick enough release film to prevent adhesion, especially on tilt‑up panels where surfaces and edges can be hard to access. Let the first coat dry, then apply a second coat (ideally in a different direction) to catch any missed spots and provide reliable release during stripping. Some situations or products may require more coats, but two is the standard minimum.
