Get Help Now. Tap to Call. Materials A traditional hard-coat stucco exterior system is extremely strong and durable because it essentially covers your home with a layer of rock. Installation Barrier EIFS is comprised of a base coat and finish coat applied over an EPS board that is attached directly to the sheathing using fasteners or an adhesive.
EIFS or traditional stucco? The Gap Test Put your hand under the bottom edge of the cladding near the foundation, assuming that is possible another common installation error occurs when the EIFS is installed below grade, making this test difficult if not impossible.

The picture on the right shows a typical system and the grey material is the "hard coat" part of the system, made up of a cement based material. EIFS is usually a little different and is known to have better water barriers and insulation properties than traditional hard coat stucco systems and most EIFS assemblies are designed to keep water on the outside of the building.
The best example would be to look at some of the most common EIFS claddings out there to get a better idea of how they work. Different manufacturers have their own special systems but the "basics" are essentially the same, having little differences between the many systems.
Basic EIFS Assembly: The picture on the right illustrates a basic EIFS system that is an Omega Stucco system and uses an adhesive on the substrate, foam insulation board, a base coat that is embedded with mesh and a finish coat.
The main difference between this system and a hard coat system is the adhesive base used to adhere the foam to the substrate and a different finish coat that is designed to keep out water. An EIFS Assembly With Added Water Management System: EIFS claddings can have specialty layers within the assembly that serve a specific purpose and the two most common layers help to keep out moisture and air and are usually referred to as moisture barriers and air barriers.
The picture on the right illustrates an EIFS cladding that uses a water barrier on the substrate red layer before the adhesive is applied. There are also different types of finishes that are available as well and these can have their own advantages and disadvantages.
They can also have different appearances which can make your exterior stucco look a specific way when compared to the other type of finish materials. Cement Based Finishes - Cement based finishes are made from a white Portland cement instead of a dark gray Portland cement that is typically used on the base coats of a hard coat stucco system. The base is white so that you can add color to the material in order to get an even, integrated color in the finish coat.
Acrylic Finishes - Acrylic finishes are made of acrylic that have an aggregate added to them in order to achieve a desired look. You may not be aware that adhesive tape is an important tool used in exterior stucco application. Stucco composite can damage windows and frames if it accidentally comes in contact with it during the application process, so contractors make sure to mask them off using a tape that is specifically designed to 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.
Additionally, tape is used to create a watertight seal to protect surfaces not meant to get wet, as explained in the common problems section. Plus, one of the steps in stucco application involves applying a light spray of water over the stucco surface to help it set! So why use specialty stucco tape instead of something more generic?
It all comes down to choosing the right tool for the job. This means it needs to stand up to a multitude of elements, including sun, rain, wind and even severe temperatures, before removing cleanly. If you are involved in stucco contracting work, be sure to choose a tape designed with stucco purposes in mind in order to ensure a clean, high-quality job.
