Self-Furring Lath

Definition

Self-furring lath is metal lath with dimples that space the lath away from the sheathing behind it, allowing plaster to penetrate the lath.

Purpose

The purpose of self-furring lath is to create a space between the lath and the substrate, ensuring that plaster can fully envelop the lath and create a strong bond, improving the structural integrity of plaster applications.

Examples of Use

• In stucco applications, self-furring lath provides a stable base for the plaster to adhere to exterior walls.
• Self-furring lath is used in interior plastering to ensure proper adhesion and strength of the plaster coating.
• Masonry walls may incorporate self-furring lath to support a layer of plaster or stucco.

Related Terms

• Metal Lath: A mesh material used as a base for plaster or stucco.
• Plaster: A building material used for coating walls and ceilings.
• Sheathing: A layer of material attached to the exterior studs of a building to which the lath is attached.

Notes

Proper installation of self-furring lath is crucial for achieving a durable and crack-resistant plaster or stucco finish, ensuring long-lasting performance.
