Can you install EIFS over stucco?

StoTherm EIFS can be installed over the glass-mat gypsum sheathing, wood-based sheathing, plywood, oriented strand board (OSB), masonry, plaster, concrete or stucco.

Which is better EIFS or stucco?

The fiberglass layer provides more durability, even against hard blows from weather. EIFS is notably lighter than traditional stucco, however. It is 80-percent less heavy than stucco, but it has a higher R-value, coming in between 4 and 5.6, which is notably higher than the 0.20 R-value of regular stucco.

Is EIFS stucco still used?

Yet today, EIFS are still around. About 100 million square feet of EIFS went on new and remodeled homes last year, rivaling any other siding material.

Is EIFS more expensive than stucco?

Stucco is a full masonry system that is screwed to the wall over a weather resistant barrier, so water doesn't ruin the exterior structure for a long time, even if it does get behind it. But here's the catch: EIFS installed correctly is just as good as stucco, and the labor is more cost effective.

What is the problem with EIFS?

The problems with barrier EIFS cladding all stem from water intrusion. These problems include moisture accumulation in the wall cavity, subsequent wood damage and, in more advanced cases, mold growth and the infestation of pests such as carpenter ants or termites.

Exterior Insulation Finish System (EIFS)

How long does EIFS last?

A. Dryvit EIFS are designed to last for the typical design life of a building. The actual longevity on any specific building will depend mainly on the building maintenance program. Some EIFS facades date back 50-60 years.

What is the difference between Dryvit and EIFS?

Having a house with EIFS, also known as Dryvit, isn't the end of the world. EIFS isn't a disease; it's synthetic stucco. And even though your house may have been built using it, with knowledge and proper maintenance everything can be just fine. EIFS is an Exterior Insulation and Finish System.

Is synthetic stucco the same as EIFS?

Synthetic stucco is commonly referred to as Exterior Insulating and Finish System (EIFS). Homes with this exterior finish are often strikingly beautiful, offer great flexibility in home design, and provide energy savings.

Why EIFS is the best?

Low maintenance: EIFS clad buildings have superior resistance to fading, chalking, yellowing, dirt, mould and mildew. They can be easily cleaned by just hosing them down, and hardly need painting.

How do you know if you have EIFS on stucco?

The easiest way to identify synthetic stucco (EIFS) is by touching the material with your bare hand. When you touch the wall where the stucco is installed, it will feel like plastic. You can also knock gently on the wall. If it sounds hollow and thin, you have EIFS on your home.

Does EIFS use wire mesh?

Durability of EIFS

Within the several layers and materials required for an efficient EIFS cladding is a durable mesh material. The Exterior Design Institute recommends a high-impact, reinforcing mesh that is double-strand, interwoven glass fiber.

Can you put acrylic stucco over regular stucco?

You can apply new stucco on top of old, so long as the proper measures are taken to ensure the integrity of the new layer.

Can you put Dryvit over stucco?

Tested in the lab and, more importantly, proven in the real world: Dryvit E Finish is the best high-performance solution for finishing stucco walls.

Why should barrier wall EIFS be avoided?

MOISTURE ISSUES

The barrier in any EIF system is the basecoat and mesh layer. This layer will not allow the penetration of moisture and functions as the moisture-intrusion-preventing workhorse of the system.

What is the R value of EIFS?

EIFS is an adhesively attached insulating cladding system. There are no fastening penetrations to the insulating component of these systems, the expanded Polystyrene Foam. This foam has an R value of approximately 4-per-inch of thickness at a 1-pound density.

What is the problem with synthetic stucco?

Severe Synthetic Stucco Problems

Delamination, which is synthetic stucco detaching from your home's exterior. Rotting of wood beams and trim. Mold and mildew growth, both on interior walls and beneath on the home's base walls. Infestation of termites and other moisture seeking insects.

What is the new stucco called?

Synthetic Stucco (EIFS)

It's more flexible than traditional stucco and consists of a moisture barrier, foam insulation, cement basecoat, reinforcing fiberglass mesh and an acrylic finish. Synthetic stucco is 80% lighter than traditional hard-coat and relatively durable, due to containing fiberglass.

Can EIFS stucco be painted?

On a side note, EIFS can be painted just like traditional stucco. Depending on the characteristics and appearance wanted, our professional commercial paint contractors use either top-quality acrylic latex paints or elastomeric coating systems.

What is the most common problem with Dryvit stucco?

The most common problems with Dryvit stucco are caulking and sealing issues that go unnoticed over time. This leads to serious mold issues that can get into the building structure and cause costly damage, as well as causing medical issues for residents.

Are stucco and Dryvit the same thing?

Dryvit stucco is actually the name of a stucco manufacturer, not an actual stucco system specifically. Dryvit is the name of the stucco company and they have different stucco systems including 3 coat stucco systems, EIFS systems, decorative systems and more.

Can you recoat EIFS?

Introduction The appearance of EIFS walls can be quickly refreshed by applying an appropriate coating. BASF COLOR COAT is specifically formulated for EIFS. This 100% acrylic coating minimizes changes to existing finishes.

Can you pressure wash EIFS?

The best way to clean EIFS is to use high water volume coupled with low water pressure and non-abrasive cleaners. Do not use caustic chemicals or abrasive cleaning techniques, which will permanently damage the finish.

Does EIFS crack?

Some EIFS laminas crack sooner than others, but they all eventually crack. The cracks are due to hygric and thermal stresses, embrittlement due to aging, and building movement. The cracks in EIFS laminas are often found initially at reveals and at window openings.
