Portuguese to English Bus/Financial Real Estate

A bit technical here. This is a description of the ceiling of the building being assessed for appraisal. "rebaixados" is my main doubt, so here goes my try:

"Ceilings - taped, mudded and painted, and (???) with built-in lighting."

From looking at the google images, emassar seems to mean to "tape and mud (the wall/ceiling)" but I could use reaffirmation of this.
