Stucco has been use to guard and decorate exterior and interior walls and ceilings for several centuries. Stucco is obtainable in dozens of textures, thousands of colors and is currently the cladding of choice for many new construction and remodel or restoration projects.

The two main categories of exterior stucco that encompass dozens of various systems are Hard Coat Stucco and EIFS (Exterior Insulation and Finish System). Hard Coat Stucco is that the preferred system for residential or multifamily construction, and is getting used increasingly for commercial projects since it’s more economical. EIFS is more commonly used for commercial building projects, but is usually also used for high-end custom homes.
Hard Coat Stucco is often applied in 2-3 coats with a cementitious base coat. Of the various systems out there, two of the most common are 1 Coat Stucco and 3 Coat Stucco. Traditional Three Coat Stucco consists of two coats of a cement base and one finish coat. One Coat Stucco is really a two-coat process but rather than two base coats it consists of 1 cementitious base coat with one finish coat. within the previous couple of decades One Coat Stucco has become far more popular just because of the value. The materials used and application process are virtually the identical for both systems, apart from the exception of 1 Coat Stucco taking fewer steps and fewer time. the planning ability and performance between the 2 systems are the identical, although Three Coat Stucco is often stronger and can crack less in most circumstances.
The finish coat application of both hard coat systems is that the same. There are numerous finish options but they’ll be consolidated into some categories which are: Integrally Colored Stucco, Painted Stucco, and Acrylic Finishes. Colored cement finishes or “colored stucco” was the favored choice over Three Coat Stucco for many of the 20th century. it’s simply a mix of cement, lime, sand and pigment. it’s inexpensive and straightforward to use, however, if the bottom coat cracks the finish is nearly absolute to crack. Colored Stucco will stain easily, is difficult to repair, and allows water to pass freely through it (which is good or bad counting on what a part of the country the system is applied within). it’s usually applied by hand and may achieve virtually any finish imaginable.
Painted Stucco has been around almost as long, and is that the majority of the finishes getting used today. Painted Stucco is that the same mixture of materials less the color, so it’s applied the identical and can achieve all the textures that integrally colored stucco will. the ultimate step with Painted Stucco is that the paint application. The paint, or as some prefer to call “coating”, will look more vibrant and is simpler to patch. Color options are vast and it’s important that an honest quality stucco paint is employed. the foremost desired stucco finish today is Acrylic Stucco or Acrylic Finish. Some will call this technique Synthetic Stucco, which is somewhat correct since it’s an artificial finish, however it’s not an artificial system.
Acrylic Finish is obtainable in as many colors as a paint and has the identical chemical compose as paint, but may be a much thicker application. This does raise the value of the general system, but offers many benefits that the opposite two finishes don’t. Acrylic Stucco will bridge most all hairline cracks and doesn’t allow water to travel freely into the system, which may be a huge benefit in freeze/thaw zones. Acrylic Stucco will keep its look and typically won’t require any maintenance for several years, whereas painted stucco must be repainted and repaired within some years. Colored Stucco stains easily, will show every crack and is extremely difficult to repair.
EIFS may be a full synthetic system or what most will call Synthetic Stucco. EIFS systems weigh much but traditional stucco and are far more flexible. Although most EIFS adhesives and base coats are cement based, they’re heavily polymer modified in order that they are considered synthetic. These variety of systems are used successfully for several decades but are much newer within the stucco world. Most all EIFS systems use EPS (Expanded Polystyrene) insulation board which is sometimes adhesively attached to the substrate and sometimes mechanically attached.
The original or traditional EIFS systems all used a cement-based adhesive and/or mechanical fasteners for the EPS, fiberglass netting for reinforcement and to measure base coat thickness, cement base coat, and an acrylic finish. These systems are referred to as Barrier EIFS. Since these systems are so watertight, they’ve had some problems like not allowing water to flee after it had travelled into the system thanks to improper application and flashing. The industry quickly designed Drainage EIFS or Water Managed EIFS which some manufacturers had and promoted before these issues arrived. Drainage EIFS systems are highly regarded in recent years and include added or altered components like notched or channeled EPS, plastic trim, trowel or roller-applied waterproof coatings. These systems seem to own remedied the water drainage problem of years past. The finish coat options for EIFS aren’t as vast as they’re for Hard Coat Stucco. Since EIFS may be a “soft system” or synthetic system, cement finishes won’t work unless they’re acrylic or polymer modified.
Most EIFS manufacturers have their recommended systems and can not warranty their products if deviated from the initial specifications. Almost every final coat for EIFS consists of an acrylic emulsion and marble or silica sand finish that’s hand-troweled over the bottom coat. Acrylic finish is integrally colored and extremely flexible. There are some standard textures that acrylic finishes provide, including Smooth Finish, Sand Finish, and Rilled or Swirl Finish. These finishes, which are expensive, are usually applied in one coat at a thickness of 5/32″ or less. many various textures are possible by multilayering an acrylic finish.
