This portable device is held against the surface we are testing and can scan through roughly 60 layers of paint—without the destructive need to cut a paint chip sample to send to a lab. The device will provide a positive result for Lead-Paint if it reads >0.7µg/cm² (micrograms per centimeter squared; the unit of measurement for determining how much lead is in paint), or Negative for anything less.
Your results will be compiled into a report, and any areas identified as containing lead will be specified by Room, Type, and Material—for example, your report may say: POS, 0.9µg/cm², Bedroom: Wall A, Baseboard, Wood.
Dust wipe testing certainly has its place in the world of lead paint inspections, but it’s not going to be your best option when trying to figure out if lead paint exists in your home. As lead paint deteriorates it can begin to flake, chip, or peel—and constant friction from doors and windows rubbing can create an extremely fine dust. This dust is very heavy and doesn’t linger in the air long—so, why is it a concern then? Children that crawl on the floor could put their hands in the dust, and then do what all children do… put their hands in their mouth; it’s the ingestion of lead paint that is the most harmful.
