Q.: On a recent project, we encountered a problem with excess bond breaker left on tilt-up panels. What is the best way to get the bond breaker off of panels so they can be painted successfully?

A.: Many manufacturers of curing compounds, sealers, and bond breakers also make strippers that can remove their products. We recommend that you ask the bond breaker manufacturer for advice on the best chemical stripper and cleaning method to use. The effectiveness of a stripper will vary depending on the bond breaker's composition. Among the chemicals that have been used in strippers are D-limonene (derived from citrus peels) and methylene chloride.
