Translation guide
The English word 'undercoat' can refer to a layer of paint or primer, or to the soft, dense fur beneath an animal's outer coat. This guide covers both meanings, with a focus on natural Japanese expressions for each context.
A layer of paint or primer applied before the topcoat, often for protection or adhesion.
The most common and direct term for an undercoat in painting, priming, or coating contexts. Used as a noun or suru-verb.

The standard biological term for underfur or undercoat of animals. Used in zoology, pet care, and textiles.
この犬種は下毛が密生しています。

下塗り is the general Japanese term for any undercoat layer. プライマー specifically refers to a primer product, often with chemical bonding or anti-corrosion properties. アンダーコート is a direct loanword and may be understood but sounds less natural in most contexts.
