Top 10 Questions for Lath Hand Interview

1. What are the different types of laths used in construction, and what are their respective advantages and disadvantages?

There are three main types of laths used in construction: wood lath, metal lath, and gypsum lath.

• Wood lath is the oldest type of lath and is made from thin strips of wood. It is relatively inexpensive and easy to install, but it is not as fire-resistant as other types of lath and is susceptible to rot and insects.
• Metal lath is made from thin sheets of metal, usually galvanized steel. It is more fire-resistant than wood lath and is not susceptible to rot or insects. However, it is more expensive and difficult to install.
• Gypsum lath is made from gypsum plaster and is applied in a thin layer over a backing of paper or fiberglass. It is fire-resistant, rot-resistant, and insect-resistant. However, it is more expensive than wood lath and is not as strong.

2. What are the steps involved in installing lath?

Preparation

• Inspect the surface to be lathed to ensure that it is clean, dry, and free of debris.
• If the surface is uneven, level it using a leveling compound.
• Apply a coat of primer to the surface to help the lath adhere.

Installation

• Start at one corner of the surface and install the lath in rows, overlapping the edges of each piece by about 1 inch.
• Secure the lath to the surface using nails or screws, spacing them about 6 inches apart.
• Continue installing the lath until the entire surface is covered.

Finishing

• Once the lath is installed, apply a coat of plaster or stucco to the surface.
• Allow the plaster or stucco to dry completely and then sand it smooth.

3. What are some common problems that can occur when installing lath?

• The lath may not be installed properly, which can cause the plaster or stucco to crack or fall off.
• The lath may not be moisture-resistant, which can cause the plaster or stucco to deteriorate.
• The lath may be damaged by insects or rodents, which can weaken the plaster or stucco.

4. What are the safety precautions that should be taken when working with lath?

• Wear a dust mask to avoid inhaling dust from the lath.
• Wear gloves to protect your hands from cuts and abrasions.
• Use a sharp knife or saw to cut the lath, and be careful not to cut yourself.
• Be aware of the location of electrical wires and plumbing pipes before installing the lath.

5. What are some tips for installing lath quickly and efficiently?

• Use a chalk line to mark the location of the lath on the surface.
• Use a nail gun to secure the lath to the surface, which is much faster than using a hammer and nails.
• Overlap the edges of the lath by about 1 inch to ensure a strong bond.
• Work in small sections to avoid making mistakes.

6. What are some of the latest trends in lath installation?

• The use of self-adhesive lath, which eliminates the need for nails or screws.
• The use of lightweight lath, which is easier to install and transport.
• The use of pre-cut lath, which saves time and reduces waste.

7. What are some of the challenges that lath installers face?

• Installing lath on uneven surfaces.
• Installing lath around obstacles, such as pipes and wires.
• Working in tight spaces.

8. What are some of the tools that lath installers use?

• Chalk line.
• Nail gun.
• Hammer.
• Screwdriver.
• Utility knife.
• Level.

9. What are some of the materials that lath installers use?

• Wood lath.
• Metal lath.
• Gypsum lath.
• Nails.
• Screws.
• Primer.
• Plaster.
• Stucco.

10. What are some of the safety regulations that lath installers must follow?

• Wear a dust mask.
• Wear gloves.
• Use a sharp knife or saw.
• Be aware of the location of electrical wires and plumbing pipes.
