Answer :
Final answer:
A narrow strip of expanded metal lath used for:
1) Reinforcing joints in gypsum lath
2) Junctures between different types of plaster base
Explanation:
A narrow strip of expanded metal lath is typically used in construction to reinforce joints or to provide a stable transition between different types of materials. When it comes to gypsum lath, for example, an expanded metal lath strip can be used to strengthen the joints, helping to prevent cracking by distributing stresses across a larger area.
The correct answer to the student's question is: A narrow strip of expanded metal lath is primarily used for reinforcing joints in gypsum lath and for providing support at junctures between different types of plaster bases. This usage is essential in achieving a durable and seamless finish in various construction and plastering projects. Thus the right option is 1 and 2.
Final answer:
A narrow strip of expanded metal lath is used for reinforcing joints in gypsum lath and junctures between different types of plaster base.
Explanation:
A narrow strip of expanded metal lath is used for reinforcing joints in gypsum lath and for the junctures between different types of plaster base.
Expanded metal lath is a mesh-like material made from thin metal sheets that have been slit and expanded. It provides strength and stability to the joints in gypsum lath, preventing cracks and ensuring a smooth finish. It is also used to reinforce the junctures between different types of plaster base, such as at the corners or edges of walls.
