What is the primary characteristic of the lath and plaster method?

The primary characteristic of the lath and plaster method is that it requires applying wet plaster to wood slats. This traditional construction technique involves using wooden laths—thin strips of wood attached to wall studs—to create a base. The wet plaster is applied over these laths, which allows the plaster to adhere and cure to form a solid, rigid wall. This method has been used for centuries and provides a strong, durable finish.

The wet application process is essential in this method, as it directly influences the integrity and appearance of the walls. Once cured, the plaster creates a smooth surface that is suitable for painting or other finishes.

In contrast, painting directly on drywall does not involve plaster or laths, using a completely different material and method. The use of only synthetic materials isn't characteristic of the lath and plaster method, as it traditionally relies on natural wood and plaster. Additionally, lath and plaster is regarded as a historical method rather than a modern one, which further distinguishes it from contemporary construction techniques.
