What does dealbation mean?
Dealbation is an obscure English noun meaning the act of whitening something, particularly the application of a white coating such as whitewash to a wall or surface. Derived from the Latin verb dealbare, 'to whitewash,' it belongs to a family of terms rooted in albus, the Latin word for white — the same root that gave English words like album, albumen, and albino. The word appears chiefly in historical and technical contexts: older texts on painting, building, and pharmacy occasionally use dealbation to describe a finishing or brightening layer applied over a surface. Today it survives only as a curiosity of lexicography, encountered mainly in unabridged dictionaries and etymological discussions. Its connotations are purely descriptive rather than evaluative — dealbation names a process, not a quality. For readers interested in the hidden Latin ancestry of ordinary vocabulary, dealbation offers a striking example: a word so thoroughly forgotten that even its subject matter, the humble act of whitewashing, has long since adopted simpler names.
nounThe action or process of whitening something; the application of a white surface, such as whitewash, especially in painting or coating.

"In Renaissance treatises on pigment, dealbation was described as the final, brightening layer applied over a ground."
A plural form is theoretically possible but essentially unattested; the noun is normally used in the singular.
"The manuscript describes several dealbations used by medieval limners."
Every time you say 'album' you're using the same Latin root as this forgotten word for whitewashing — albus, the Roman word for white.

Etymology of dealbation
Dealbation derives from the Latin verb dealbare, meaning to whitewash or make white, itself formed from de- plus albus, the Latin word for white. The term entered English through learned borrowing, appearing in historical dictionaries of the seventeenth century onward alongside other technical terms of painting and building. It shares its ultimate root with a notable group of English words drawn from albus, including album, albumen, and albino.
How dealbation is actually used
Extremely rare; found almost exclusively in historical dictionaries and older technical writing on painting and plastering. It carries no everyday register and would be unfamiliar to most modern readers.
