Stucco provides a durable, low maintenance finish that adds lots of character to a house. It can be applied with either one coat or three coat process, but there is some confusion about the methods. Let’s take a look at each technique as well as the advantage that each has to offer:
什么是三层涂层灰泥？
Three coat is the original stucco process, consisting of paper and wire, a scratch coat, a brown coat, and a finish, or “top” coat. In industry terms — lath, scratch and brown. The finish coat is not considered a step because it is needed on every type of application that is used, so they are mainly referring to the stages up until the finish coat.
More specifically, a lath of an asphalt-infused paper is applied over a weather-resistant barrier. Then a layer of furred chicken wire (meaning it sticks off the wall a little bit) is applied. Next comes the scratch coat, which is a base layer of field-mixed Portland cement, sand, lime, and water with a series of horizontal lines scratched into it. Then comes the brown coat. This layer is applied with a darby, or long trowel, to make sure the cement is applied evenly. Finally, a finish coat is put on with a hawk and trowel and it can be applied in a variety of textures. These coats come in a range of colors so no additional painting is needed.
The big advantage of three-coat stucco is its strength and durability. Since it is twice as thick as one coat it’s better able to hold up to wear and tear. The two drawbacks are time and cost. It can take weeks for each layer to be applied and cure. As a result, the extra materials and labor make three-coat more expensive than the one coat option.
What Is One Coat Stucco & What Is The Benefit?
术语涂层灰泥是指波特兰水泥，砂，纤维，特殊专有化学品和水的混合物。这种方法通过将划痕和棕色外套组合到3/8“至1/2”厚的单一施加中，加速了三种涂层灰泥过程。它通常施加在刚性泡沫板和板条上，以提供能量码所需的连续绝缘耐用包层。
That said, the term “one coat” is a misnomer because the first iteration had the colored finish coat mixed into the blend. Unfortunately, it resulted in uneven color and fibers that were visible at top layer so the two-coat method was adapted.
The one coat method is growing in popularity due to the advantages of speed and cost. Unlike three-coat, one coat saves money because the application takes approximately half the time resulting in quicker job completions, reduced labor costs, low maintenance, and life-cycle cost ratio. Yet, One Coat Stucco provides all the same benefits expected from three-coat stucco…durability, design flexibility, and fire resistance. The downside is that the thinner depth makes it is more susceptible to damage.
灰泥和家庭建筑的常见问题
Stucco is actually a porous material and is designed to allow the absorption of water. Housewrap, or water-resistive barrier, acts as a drainage plane, and as the stucco dries, water flows down the building paper and weeps out the bottom of the stucco. As long as the sheathing stays dry and water does not get trapped in the wall cavity, problems will be rare. But… they do still happen.
重要的是，高性能建筑专业人员和承包商了解这些问题，因为水进入系统时宽容得多。例如，使用Housewrap作为防水屏障（WRB）。房子包装主要是防水质量的空气障碍。由于对指定使用WRB的建立代码的更改，承包商应该知道，为了正常运行，需要在灰泥和WRB之间进行空间，使水可以干燥。如果不遵守作为最好的实践，水可以被捕获并降低整个墙壁组装，不仅导致黑色模具的生长，而且劣化了建筑物的结构完整性。
Also, improper window flashings continue to be an issue, as the stucco cladding is most vulnerable to excessive quantities of water entering the wall assembly at window flashings and roof wall connections.

You may not be aware thatadhesive tape是外部灰泥应用中使用的重要工具。如果它在应用程序过程中意外接触它，灰泥复合材料可能会损坏窗户和帧，因此承包商确保使用磁带屏蔽它们金博宝188备用地址specifically designedto keep a strong hold against plaster and withstand intense sunlight and fluctuating temperatures. It is also important for the tape to be able to hold up heavy plastic sheeting that is used to keep windows and other surfaces clean and protected while stucco is being applied.此外，胶带用于创建水密密封，金博宝188备用地址以保护表面并不意味着湿润，如常见问题部分所述。（加上，灰泥应用中的一个步骤涉及在灰泥表面上涂抹水的浅喷雾，以帮助它！）
So why use特种灰泥胶带金博宝188备用地址而不是更通用的东西？这一切都归结为为这项工作选择合适的工具。灰泥作品需要专门设计的胶带，专门用于存活膏金博宝188备用地址药的重量;坚持多个表面，不仅仅是混凝土和木材;并没有离开渣when it’s removed 7, 10 or even 60 days later. This means it needs to stand up to a multitude of elements, including sun, rain, wind and even severe temperatures, before removing cleanly.
