Abstract
A colored thermal joint compound consists of a mixture of a thermal joint compound and a powdered coloring agent of proportions sufficient to form a colloidal solution. The thermal joint compound is, for example, a zinc oxide in either a silicone oil or mineral oil base, and the coloring agent is, for example, a colored calcium carbonate powder of colloidal size particles.
