Exterior lathe work is a skilled technique used in woodworking and construction to shape and smooth the outer surface of materials like wood or metal. Lath is a crucial component in construction, serving as a foundation for plaster and other finishing materials. It is essential for building robust and resilient structures, protecting against moisture intrusion and providing a sturdy support system for new stucco or hardscape work.
Lath is essentially a framework made of thin strips of wood or metal applied to the exterior walls of a structure. The process begins with lath, which are narrow strips of wood nailed horizontally across wall studs. Metal lathes are widely used in inner and outer wall plaster systems to offer better plaster bonding property and prevent buildings from cracking. Metal lath provides a lightweight and easily attachable base for plaster application, usually applied flat across the structure.
Lathe and plaster is a more recent building technique using a similar approach to construction as wattle and daub. Lath work involves metal mesh installation on all exterior walls to support the stucco. All exterior lath penetrations must be made waterproof, and silicone holes in paper and around penetrations should be placed. Metal lath or wire fabric lath should be applied.

What is the difference between lath and plaster?
Lath and plaster is a building process used to finish interior dividing walls and ceilings, primarily consisting of narrow strips of wood nailed horizontally across wall studs or ceiling joists and coated in plaster. This technique, derived from wattle and daub, fell out of favor in the U. K. after the introduction of plasterboard in the 1930s. In Canada and the U. S., wood lath and plaster remained in use until transitional methods followed by drywall in the mid-twentieth century.
The wall or ceiling finishing process begins with wood or metal laths, which are narrow strips of wood, extruded metal, or split boards, nailed horizontally across the studs or ceiling joists. Each wall frame is covered in lath, tacked at the studs. Wood lath is typically one inch wide by four feet long by 1 ⁄4 inch thick, while metal lath is available in 27-inch by 8-foot sheets.
How to tell if a wall is lath and plaster?
The pushpin test is a method used by experts to determine the type of wall being worked on. It involves using a pushpin to press a pin on the wall, with a pushpin piercing into the wall easily. If the pin penetrates the wall, it indicates drywall, while if it doesn’t, it indicates plaster. Difficulty with a thumbtack is common with lath and plaster walls, which require a hammer. Plaster walls resist nails due to flexing laths.
If a nail gets into the plaster, the hole may be slightly larger than the nail. Knocking on drywall produces a hollow sound followed by a dense sound when reaching a stud. Plaster walls have a thick sound throughout.
What does a lath do?
The cutting tool can be moved along a workpiece in order to remove unwanted portions of the material, in a manner analogous to the use of a milling machine to remove portions of a piece of metal.
What is lathe in building construction?
Lath is a material fastened to the structural members of a building to serve as a base for plaster. It can be made of wood, metal, gypsum, or insulated board. In older residential buildings, narrow wood strips were used. Gypsum lath is a common lath, made with an air-entrained gypsum core sandwiched between two layers of absorbent paper. Sheets with reflective foil backing provide insulation and act as a vapor barrier.
Metal lath, a mesh formed by expanding a perforated metal sheet, is used in bathrooms and kitchens where ceramic tile is applied over a plaster base. These materials provide an irregular surface for keying the plaster and are commonly used in these areas.
What is exterior lath?
Exterior lath is a crucial component in building construction, providing a strong foundation for stucco and other exterior finishes. It is a framework made of thin strips of wood or metal applied to the exterior walls of a structure, ensuring proper adhesion and durability. The use of exterior lath dates back to ancient construction techniques, where it was vital for creating textured finishes that were both aesthetic and functional.
One of the main benefits of using exterior lath is its ability to support heavy materials, such as stucco, and allows for better moisture management by creating a space between the wall and the finish, allowing air circulation and preventing water from getting trapped behind the surface. Installation of exterior lath is straightforward but requires precision. Lath strips are typically installed horizontally across the walls, with gaps left in between for proper drainage and ventilation.
Choosing the right type of lath material is essential. Wood lath is traditional and provides a classic look, while metal lath has gained popularity due to its durability and resistance to rot and pests. Metal lath is especially beneficial in areas with high moisture levels, as it is less likely to deteriorate over time.
Exterior lath can enhance the aesthetic appeal of a building, offering a variety of design options, making it an appealing choice for both residential and commercial projects. Additionally, exterior lath is an eco-friendly choice for builders looking to reduce their environmental impact.
In conclusion, understanding the importance of exterior lath can help homeowners and contractors make informed decisions for their projects.
What are the benefits of lath?
The lath-and-plaster method is an old-fashioned building method that offers several advantages, including soundproofing, insulation, fire resistance, and moisture prevention. Compared to drywall, lath and plaster are better insulators for sound and heat, making historic buildings warmer and quieter. They also have better fire resistance, as they are generally better at preventing fire spread within a building. Additionally, lath and plaster walls tend to retain less moisture than plasterboard, especially if metal is used over wood lath.
However, drywall is more prevalent today due to its superior sound and heat insulation, fire resistance, and moisture prevention. While lath and plaster are outmoded wall construction materials, if properly installed, they offer numerous advantages over modern plasterboard. It is important to consider the time and resources required to install lath properly when considering alternative building materials.
What is the main purpose of a lathe?
A lathe is a machining tool used for shaping metal or wood by rotating the workpiece around a stationary cutting tool. Its primary function is to remove unwanted parts of the material, leaving a well-shaped workpiece. This tool is essential for various industries, such as woodworking, metalworking, and metalworking. The main reason for using a lathe is to create a clean, polished surface, which can be used in various projects. The lathe’s unique design allows it to create a smooth, polished surface, making it a valuable tool in various industries.
What is the function of the lath?
A lathe is a machining tool used for shaping metal or wood by rotating the workpiece around a stationary cutting tool. It removes unwanted parts, leaving a well-shaped workpiece. There are various types specialized for different materials and techniques, including live tooling capabilities at All Metals Fabricating. Lathes have been used for making parts for machinery, specialty items like bowls, and musical instruments. They all operate using a basic holding and rotating mechanism.
What are the benefits of lath and plaster walls?
Lath and plaster are older wall construction materials that offer several advantages over modern plasterboard. They provide soundproofing, insulation, fire resistance, and moisture prevention. Lath and plaster are better insulators for sound and heat, and are generally better at preventing fire spread within a building. They are also better at stemming the spread of fire within a building.
The lath-and-plaster construction method involves creating walls and ceilings out of plaster or stucco by spreading the material over a wood or metal frame (laths) and allowing it to dry. As the wet plaster moves through the frame, it accumulates on the opposite side, creating plaster keys that hold it in place.
Stucco, used for sculpture and building, has been used for centuries, but its modern use as the primary component of exterior walls only took hold in the 20th century. For exteriors, stucco is typically spread over metal lath in at least three layers.
What is the construction and working of lathe machine?
A lathe is a machine consisting of four main parts: the bed, spindle, turret, and tailstock. The main spindle rotates the material, the turret shapes the part, the tailstock supports the workpiece, and the bed is the base for the three platforms. NC lathes have the same basic configuration, including the NC device and operation screen. The bed is crucial for supporting the spindle, turret, and tailstock, as a weak bed can deform the spindle and turret, making accurate machining impossible.
What is a lath used for?
Lath is a thin, narrow strip of straight-grained wood used under roof shingles or tiles, on lath and plaster walls and ceilings, and in lattice and trellis work. It has expanded to include any backing material for plaster, including metal wire mesh, expanded metal, gypsum or rock lath, and reed mat. Key elements of lath include openings or gaps that allow plaster or stucco to ooze behind and form a mechanical bond, while gypsum lath relies on a chemical bond. Historically, reed mat was also used as a lath material.

Nice Job. The knife at the back of the rapid tacker is not as dangerous most think. This is because it gets a little gummy from the asphalt paper. Sharp enough to cut paper. You must be in So Cal. I go across country and in the east coast they hate woven wire. Keep up the good work . Mark, executive Director the Stucco Manufacturers Assoc.
For just a small job I’m going to use furring nails cause I don’t. Have a pneumatic stapler not worth it to buy or rent for a 6’ by 8 ‘. Area. I wasn’t sure how many though I know enough to nail it were the wires are intertwined and every 6″ on the studs but everything else I’m just guessing and worried about getting embarrassed at inspection.
Man this was cool to watch. This was one trade I’ve always wanted to do but instead I was a stucco labor finisher and I hated it . I lathe twice and I loved it. I remember cutting the window wire and using the sharp end of my hammer to push in the ends. I wish you would have shown the j trim around the door and explain hot it works and also that some people use t&g foam and tape. I also wish you would have shown the different style of corner bead . I remember eye balling the top of the corner bead and the bottom then using a string line to get it straight . This article brought back memories 👌🏾 oh also, for those of you who don’t know, they make double layer paper 🤙🏾
best to use double head nails when installing the wood straight edge to the corners after the first base coat has beed applied. That way it can be tightly applied and still easily removed. The wood is best being one pc, 1×4″ size is good and the length should be from the bottom to the top of the corner. It isnt necessary to plumb the piece with a level when installing it, just follow the wall and allow for the thickness of the second base coat.
Hey, I’m just asking if you were going to put some plaster stop/ J trim around the window and door? It’s not advised to go directly to the window and door frame with the mud. This should also be around the bottom. This will protect the trim and give a cleaner look. I use red tuck tape or rubber seal to seal around doors and windows when needed. Im just suggesting nothing personal. I am plasterer 1963😊 London ONTARIO Canada
metal corners will ultimatly rust, even thru paint. The proper method is to apply the base coat of mortar on the wire, than attach a temporary wood straight edge from top to bottom and apply the second base coat using that as the straight edge. When the mortar sets enough for the strip to be removed, the opposite wall can be done following the straight corner. Nothing to rust or detereorate. Same method aplies to applying stucco on recessed window and door openings on block wall construction.
