On wood framing, three-coat plaster is typically installed over metal lath to a 7/8 in. nominal thickness. A typical plaster mixture weighs about 142 pounds per cubic foot, roughly the same as mortar, and this amount of material would cover about 13.7 sq ft at 7/8 in. thick. The metal lath may add a small additional amount of weight, so the end result is that three-coat stucco weighs about 10.4 lbs per sq ft (psf) installed.

For stucco application, you should use materials such as Portland cement, sand, and water. These are the basic ingredients needed to create a stucco mixture that can be applied to surfaces like walls or ceilings. Additionally, you may also need wire mesh or lath to provide a stable base for the stucco to adhere to.
To repair stucco, first you must have a mixture of wet stucco to be applied. Sometime you can find it premixed and other times you must mix it yourself. You next remove all of the loose stucce until all of the stucco on the wall is firmly stuck to its lath. Then, you replace the paper and the metal mesh. Next you would slather on the wet stucco and smooth out.
Work from the bottom up. That means your first "layer" of metal lath goes on the bottom, stretched upwards. Next row is above it, stretched downwards. Hope this makes sense =)
Diamond mesh lath and rib lath are both types of metal lath used in construction for plastering and stucco applications, but they have distinct features. Diamond mesh lath has a diamond-shaped pattern that provides better plaster bonding and flexibility, making it ideal for curved surfaces. Rib lath, on the other hand, features raised ribs that enhance structural strength and support heavy plaster applications, making it suitable for more demanding environments. Ultimately, the choice between the two depends on the specific requirements of the project.
No, stucco should not be applied directly to plywood as it requires a proper substrate for support and durability. Instead, a moisture-resistant barrier, such as building paper or a weather-resistant membrane, should be installed over the plywood, followed by metal lath, which provides a suitable surface for the stucco to adhere to. This ensures that the stucco has the structural integrity and moisture protection it needs to prevent damage.
The first coat of plaster or stucco is known as the "scratch coat." This initial layer is applied to a prepared surface, such as a masonry wall or lath, and serves as a base for subsequent layers. It is typically thicker and rougher, allowing for better adhesion of the following coats. After the scratch coat cures, it is typically scored or scratched to create a key for the next layer.

No. The metal lath replaces the wood furring.
Yes, fix it to the studs, NOT the lath
