What does a surface wipe (frottis) evaluate on an existing painted surface?

Explanation:
Surface wipe tests, or frottis, are used to screen for lead contamination on a painted surface, on PPE, or on tools. It provides a semi-quantitative reading, meaning you get an approximate indication of how much lead is present, not an exact concentration. This quick result helps determine whether lead exposure controls are needed before disturbing the surface during renovation or repainting. It isn’t about measuring temperature, solvent resistance, or air flow—those require different tests and tools.
