lathing
C1Technical / Trade
Definition
Meaning
The act or process of applying laths (thin, narrow strips of wood or metal) to a wall, ceiling, or framework as a base for plaster, tiles, or other covering.
The material or structure composed of laths; the preparatory work in construction for a finishing surface. Can also refer to the process of cutting or shaping material on a lathe (though this is less common and overlaps with 'turning').
Linguistics
Semantic Notes
Primarily a gerund (verbal noun) from the verb 'to lathe' in its construction sense. In modern usage, it is almost exclusively a technical term in building trades. The lathe-machine sense is now rare for this form; 'turning' is preferred.
Dialectal Variation
British vs American Usage
Differences
No significant difference in core meaning. The process and materials are identical. Terminology for specific lath types (e.g., 'expanded metal lath') is shared.
Connotations
In both varieties, it connotes skilled manual trade, historical building methods, or specific modern drywall/plasterboard installation techniques.
Frequency
Equally low-frequency in both dialects, confined to construction contexts. Possibly slightly more frequent in UK English in reference to traditional plasterwork renovation.

FAQ
Frequently Asked Questions
Historically, yes, as both come from an Old English word for a 'board' or 'strip'. However, in modern technical use, they are distinct. 'Lathing' (construction) and 'lathe' (the machine for shaping wood/metal) are now separate semantic fields. The activity on the machine is called 'turning', not 'lathing'.
They are very similar. 'Lathing' specifically refers to installing the strips (laths) that form a base for plaster or tiles. 'Furring' (or 'furring out') is a broader term for adding strips of wood or metal to a surface to level it, create a cavity, or provide a fixing base; it can be a synonym for lathing or a preceding step.
Yes, but the materials have evolved. Traditional wood lath is used in restoration. Modern construction uses 'metal lath' (expanded diamond-mesh metal) as a base for cementitious coatings like stucco, or as reinforcement. It's also a key component in some fireproofing and veneer plaster systems.
Rarely. It is primarily an uncountable mass noun referring to the material or the process. You would say 'some lathing' or 'the lathing'. To refer to a single piece, use 'a lath'. The plural 'lathings' is almost never used.
