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 =)

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

There are a wide variety of 'stucco' products on the market. The "Tried and True" method of installing the lath (metal screen to reinforce the coating); the 'brown coat'; and then the finish coat, create a great number of variables. If the application is done with the least expensive materials possible, a 1" thick stucco will cost between .50 and 1.50 dollars per square foot for materials; however, this method will have long term maintenance cost due to severe 'cracking' in virtually any climate. The labor cost of installing will be from $4 per square foot to $15 per square foot, dependent upon the quality of the provider/installer, and the materials selected. Synthetic stucco coatings run approximately $1.80 per square foot as of mid 2012 nationwide average... for the top coat only. Stucco is a very viable, durable and long lasting finish for both residential and commercial construction; however, as with all things ~you get what you pay for... but, don't assume that because the cost is "cheap" so will be the end product; nor does the quoted price being expensive reflect a quality end product. Do the research; educate yourself; then choose the materials, and more importantly, carefully select your contractor. From having installed thousands of square feet of stucco, I can assure that the capable DIY installer, if haven taken the time to familiarize with the products available; shopping around; and practicing on perhaps the interior of your garage... can install a quality stucco exterior, comprised of 1" space 'chicken wire' as lath; a quality portland and screened sand (use #4 sandblasting sand; consistent in size, and comes in 100 lb bags); mixed in a 2 parts sand to 1 part dry portand (white is preferable, thus giving ease of coverage with a quality topper); followed by a synthetic top coat which 'breaths', can be done for around 1.50 to 2.50 per square foot (not counting your time)... Use $2.50 per square foot as a base for materials, and you'll be able to determine the amount the contractor is considering as 'cost' ~the rest is labor. Hope this helps you... Stucco application is an "art" which looks much easier that it is... but it's worth the time to learn and the end product is beautiful, long lasting, and if properly done, far stronger than brick veneer, as it becomes an integral structural component of the wall; providing addition strength, and long lasting aesthetic appeal, with the versatility of color change, if the need arises, through the re-coat of the 'top-coat', available in a plethora of colors, custom mixed to the designer or owners desire. This is based on cost of materials available to the consumer, during the fall of 2012, in the Southwestern US ~and may vary widely dependent upon availability, local and UBC codes, homeowner association guidelines; as well as countless other variables. Good luck to all future stucco enthusiasts! It's an ancient finish that keeps on working ~that says a lot.
When applying expanded metal lath, there is typically a preferred "up" direction, which is indicated by the raised surface of the metal. This orientation ensures better adherence of plaster or stucco, as the texture helps to grip the material effectively. Installing the lath with the raised surface facing up promotes proper bonding and enhances the durability of the finish. Always check for specific manufacturer recommendations, as practices may vary.
