What is the significance of the framework of wood slats in the lath and plaster method?

The framework of wood slats in the lath and plaster method serves a crucial structural function. When wet plaster is applied, it must have a means of support to prevent it from sagging or collapsing as it dries. The wood slats, or lath, create a base that holds the wet plaster in place, allowing for a strong adhesion and ensuring that the plaster sets properly without damage. This method enhances the structural integrity of the wall and contributes to the overall durability of the plaster finish, facilitating a solid bond that reinforces the surface. The correct choice highlights the functional role of the lath rather than suggesting it serves only aesthetic or decorative purposes.
