What does encrusting mean?
"Encrusting" is the present participle of the verb "encrust," meaning to cover something with a hard, often irregular outer layer. Barnacles encrust a ship's hull, mineral deposits encrust pipes, and lichen encrusts stone — anywhere nature or time builds up a stony, salty, or gritty surface. A secondary, more ornamental sense describes setting a surface with precious materials, as in a sword hilt encrusting itself in legend or a crown encrusted with gems, though this sense more often appears in the passive form "encrusted." The word carries a connotation of gradual accumulation and permanence: what is encrusted has usually taken a long while to build up and resists easy removal. It derives from "crust," tracing back through Old French to the Latin "crusta," meaning a hard outer shell or rind, making it a close cousin of "crustacean." Writers reach for it when they want to convey slow, stubborn, layered deposition rather than a simple coat of paint or dust.

Etymology of encrusting
Encrusting comes from "encrust," formed in English by adding the prefix "en-" to "crust." The noun "crust" entered Middle English from Old French "crouste" (modern French "croûte"), which derives from the Latin "crusta," meaning a hard outer shell, rind, or bark. The Latin root also gave rise to "crustacean," coined for shell-covered creatures, and ultimately to culinary terms like "custard," via Anglo-Norman. The extended sense of covering with jewels developed from the idea of laying a solid layer of ornament over a surface.
