We would not recommend painting over the Caliwel. Caliwel is a zero VOC non-toxic paint that utilizes natural hydrated lime to inhibit the growth of mold and mildew. It has a pH of 12.4 which works only through direct contact. If you cover it up with paint, there will be no direct contact and the Caliwel will be sealed up. It won't hurt anything to paint or seal over it, but it just won't perform as expected to prevent mold growth.
