schejamassa/chejamassa

[OTTO_75]

Have found a document for our old house where it is described that there is schejamassabeläggning (in poor condition) in the bathroom.
What does it mean? What function does schejamassa have? Is it a coating used for entire floors... or just around drains... or?
There are few hits on Google, but from what I can understand, there is asbestos in the schejamassa...

Schejamassa, named after the inventor/manufacturer engineer Oscar Scheja, consists of a mixture of sand, cement, and asbestos. The compound was marketed from 1899 by the firm Jacob Scheja. It was used on floors and walls where a larger, smooth, seamless surface was desired. The compound was primarily used during the first half of the 20th century. During remediation, it should be treated as asbestos.
