Adhesives and primer compositions that include water, a polymer and a pH indicator. The adhesives and primers have a visually-detectable color when wet, and preferably dry to a clear or transparent film, while having good flow and spreadability. The adhesives and primers provide a visual indication of wetness by including a pH indicator such that when the composition is wet, the pH indicator is colored such that the color and the intensity of the color provides a visual indication of wetness; sufficiency of thickness; and uniformity of application of the adhesive or primer.
