Moisture Detection Test Paper

Large, 8x10" cobalt chloride moisture detection sheets are a fast and easy way to identify leaks in roofs, between walls, inside car doors or under ceramic tiles.

The moisture detection paper sheets shown in the image below are 8x10" (200x250mm). They react by turning a light pink color immediately when exposed to liquid water or slowly when exposed to greater than 55% humidity. The sheet in the top left corner was placed in a slightly damp basement overnight & has started to change.

They differ in their use from the individual strips because they will allow for identification of spray or leakage patterns when left in enclosed spaces such as under roofing shingles, inside car doors or under ceramic tiles.

You can also cut them into larger pieces than the standard strips if you need to. These sheets are available by special order in even larger sizes and with an adhesive backing. Call for details; minimum orders apply.

Note: The reaction is reversible. If the sheets are heated or the surrounding air goes dry, these will revert back to their blue color.
