传统的现代灰泥是在建筑外部涂上三层波特兰水泥灰泥。灰泥比某些类型的包层(例如乙烯基和某些类型的木材)更贵，但表面耐用，透气性好，防火，适合任何气候，并有适当的细节。只要表面已经安装了细节，以解决向内的太阳蒸汽驱动和风驱动的雨，粉刷应该不需要什么维护，除非表面损坏。灰泥覆盖层有很多类型，但它们最好可以分为三种主要类型:传统的三层灰泥;更新的单层灰泥;以及外部绝缘和饰面系统(EIFS)。每种系统都有其优点和缺点。每个系统都可以是一个耐用的、保护性的包层，但每个系统都需要一套不同的安装细节来实现这些结果。每一个都可以创建一个外部的空气屏障，再次依赖于穿透、过渡和墙壁覆层边缘的细节。三层灰泥是一种长期使用的非专利覆层系统，先有划痕，然后是底漆，然后是面漆，最终形成7/8英寸到1英寸厚的覆层。 This system is the most time and labor intensive. One-coat stucco systems have just one base coat about 1/2-inch thick with a thin finish coat, so these claddings are sometimes called “two-coat.” The base coat is a blend of portland cement, fibers, and proprietary additives, with each system carrying its own International Code Council (ICC) Evaluation Service (ES) report that dictates the installation details. There is less labor and time required for this system than three-coat stucco, but custom installation standards must be followed. Exterior insulation and finish systems (EIFS) are essentially one-coat systems, but the marriage of a stucco finish to exterior rigid insulation brings with it different water-management details than the…
