In architectural finishes, “lacquer” is best described as which of the following product types used for clear, fast-drying films? Pick the correct definition.

Introduction / Context:
Lacquer finishes are common on furniture, doors, and trim where rapid drying and clarity are needed. Understanding what lacquer actually is helps in selecting thinners, substrates, and application methods (spray or brush).

Given Data / Assumptions:

• Lacquer is traditionally made by dissolving resin (e.g., shellac or nitrocellulose types) in a volatile solvent, commonly alcohol or specific lacquer thinners.
• Application aims for a clear, hard, fast-drying film.

Concept / Approach:

In building and woodworking terminology, a lacquer is a spirit-type varnish where the binder is soluble in an organic solvent (often alcohol for shellac or lacquer thinner for nitrocellulose). It is distinct from oil paints (oxidative cure), distempers (water-based whiting and glue), and modern waterborne acrylics.

Step-by-Step Solution:

Verification / Alternative check:

Finishers’ guides specify spirit varnishes and nitrocellulose lacquers as classic lacquer systems with rapid evaporation and quick reuse times.

Why Other Options Are Wrong:

Oil paint: pigmented, slow-drying film. Distemper: chalky decorative coat. Waterborne acrylic: different chemistry and drying mechanism.

Common Pitfalls:

Calling any clear coat a “lacquer”; solvent system and resin type matter.

Final Answer:

Spirit varnish (alcohol-soluble resin) for quick-drying clear coats
