White powder under carpet.

Mold typically smells damp or musty. Sometime vinyl and other materials break down and the result is a powder under the carpeting.

The white powder of which appears underneath a tufted rug is actually dried up particles from the glue which had once held wool securely to the canvas or foundation of the rug.

Hand tufted rugs are constructed from different parts that are glued together. In cool climates mold growth on floor joists is rare. There is a canvas with the design mapped out that the wool strands are inserted into using a tufting gun. But when it occurs it s often white in color.

On mine at least it s definitely latex from the backing that s bonded to the rug. White mold is often found in two locations in a crawlspace exposed soil and the lower portions of the floor joists.
