WHAT IS STUCCO?

Stucco is hard and durable wall coating which is applied either to the indoor or outdoor surfaces of buildings. It is a type of siding that is cement based or EIFS – provides a seamless wall finish and has countless textures and colors to choose from It is also rot and fungus resistant. Cement stucco systems offer a low maintenance, long-lasting, and impact resistant siding. It is versatile and can be applied to concrete, concrete masonry, brick, wood frame, or steel frame. It is fire resistant and color retentive. Thus, various pigments can be added to the plaster to give your stucco exactly the appearance that you are looking for. The variety of systems, styles and colors will show off your personality and fit your property style. Stucco is not only an affordable exterior solution for your home or office but can also make your property protected and strong for years to come.

Stucco Systems

CEMENT BOARD STUCCO WALL SYSTEM

Cement Board Stucco Wall System using PERMA BASE brand is the newest system on the market. It combines all advantages of traditional stucco and EIFS system, without creating cracks (typical in EIFS system)
Cement Board Stucco is a water- managed exterior wall system designed to provide increased high-impact and weather resistance and improved dimensional stability where exterior insulation value is not required.
It combines the strength and durability of PERMA BASE (brand) Cement Board with the performance and beauty of reinforced base coats and textured finishes.
All finishes are available in a limitless color selection and offer performance enhancements options ranging from extra mildew resistance to added flexibility.
For the purpose of meeting structural racking or fire code requirements, it is applied over the following approved sheathings: Exposure 1 or exterior plywood (grade C-D or better); Exposure 1 OSB; glass mat gypsum substrate meeting ASTM C 1177.
Behind the system, a weather resistant barrier complying with ASTM D-226 protects approved sheathings and other structural components and serves as a component to evacuate incidental water.

Uses:

FOR HIGH IMPACT AND WEATHER- RESISTANT EXTERIOR WALL IN RESIDENTIAL AND LOW-RISE COMMERCIAL APPLICATIONS

ADVANTAAGES:

Durability & Strength – moisture resistant, durable PERMA BASE Cement Board substrates applied over a primary sheathing provide extraordinary impact & puncture resistance to the system.
Weather Resistance – 100% Acrylic base coats and finishes repel weather at the system’s surface.
Water-Managed Design system – provided drainage to the exterior of incidental water that might enter around and through window and door openings and penetrate behind the layer in frame construction
Design Options – provides the popular stucco look, including the attachment of special pre-molded shapes and a wide variety of finish texture and color options in standard colors and custom colors.
The following manufacturers list the PERMA BASE Cement Board as a component: STO, PAREX, SENERGY.

TRADITIONAL HARD COAT STUCCO

Traditional hard-coat stucco is strong and extremely durable because it essentially covers your home in a layer of rock.
Will hold up better to dings, hail, woodpeckers, and anything else that may come knocking.
Sometimes described as porous, traditional stucco also permits moisture to move freely, in and out of the wall cavity, which means that stucco is a great choice in extremely moist climates.
Unfortunately, even when stucco walls are properly equipped with expansion joints and control joints, stucco can crack on the field of the wall
If you are designing in an extremely wet climate, you may choose to work with traditional stucco.

EIFS STUCCO SYSTEM (SYNTHETIC STUCCO)

Non-load bearing, exterior wall layer system that consists of an insulation board attached either adhesively or mechanically, or both, to the substrate; an integrally reinforced base coat; and a textured protective finish coat. EIFS can first be boiled down into a polymer-based or non-cementitious coating (sometimes referred to as “synthetic stucco”), that is fixed on top of an insulation panel.
Professionally installed EIFS does not typically produce cracks because of the reinforcing glass-fiber mesh that is embedded in the base coat. If EIFS does crack, the cracks will be smaller and typically around penetrations such as windows and doors, where proper joint provisions were not provided.
EIFS is probably softer than traditional stucco, the material boasts better insulation and higher energy efficiency because of its multiple layering.
It also features an exterior finish that will not yellow or fade (as is often the case with traditional stucco).
In contrast, EIFS is more like to be damaged by water. Once water penetrates behind the EPS board, it will be more difficult to drain it back out.
If you are going for customized accents or working in extreme climate conditions, you may choose to work with EIFS due to its highly flexible aesthetic and insulating qualities.

TRADITIONALM (HARD COAT STUCCO) VS. EIFS (SYNTHETIC STUCCO)

Portland cement plaster (traditional hard coat stucco) should not be confused with the Exterior Insulation and Finish System (EIFS or synthetic stucco) systems that are popular but have performance problems, including water leakage and low impact resistance.
EIFS is a system composed of several layers installed directly over exterior sheathing such as plywood. EIFS consists 1/8” layers of acrylic applied over an insulation board such as polystyrene.
Traditional hard-coat stucco is a time-tested exterior breathable finish. It consists of Portland cement and sand mixed with water to form a workable plaster.
Portland cement, the same material that is the basis for the hardened properties of concrete used to build super-highways, bridges, and skyscrapers provides strength, durability, and toughness in Portland cement plaster.
While the acrylic coatings repel water very effectively, problems arise when moisture gets behind the EIFS synthetic stucco and is trapped inside the wall.
Trapped moisture eventually rots insulation, sheathing, and wood framing. It also corrodes metal framing and metal attachments.
There have been fewer problems with EIFS used over solid bases such as concrete or masonry because these substrates are very stable and are not subject to rot or corrosion.
