Repair and EIFSrecoating and overcladding may become necessary at some point in the life of EIFS structure.
To enhance the curb appeal of your building, recoating may be something you will feel is necessary at some point. By using the new science of EIFS lamina and shapes, your existing structure can be artfully changed and designed in order to achieve a totally new look in appearance due to the design you have chosen. If you are planning on selling or renting this is something you may want to look into, although if your building just needs some repair, an overcladding may be all you will need at this time and will be cost efficient.
If you can see every piece of foam on the wall the applicator has missed a crucial step
The other day a came across an EIFS house that I could see every piece of foam on. I have seen some EIFS applications where in the right sunlight you could see a few pieces of foam, but this was the worst you could literally see every piece of foam. The home owner naturally asked me how this could have happened. Apparently the contractor told him that is just how it looks. I can tell you that, that is not true. There is a few reasons that could have happened and in this case it was probably all of the above. If the foam is not rasped or rasped correctly you will be able to see the foam pieces after the job is done. Also, the adhesive used to adhere the foam to the wall can get in between the pieces, and cause gaps. The gaps will dry at a different rate due to moisture and heat flow, and that will cause them to be seen. I have purchased foam that was not all exactly the same thickness, which if not rasped down will cause the pieces to be seen, but this is very rare I have only seen this a couple times in my 23 years in the industry.
In the case I just seen I am sure they did not rasp the foam at all, and when sticking the foam they did not make sure the pieces where applied tightly together, which caused the finished product to look like that. To fix the wall it now needs to coated with two layers of base coat. The first layer to fill in all the seams to even them out. The second layer is a complete coat over the entire wall to blend everything together. This process to repair the wall takes a highly skilled plasterer. Short of that you would have to re-stick the entire wall, essentially redoing the wall over the existing EIFS.
Commercial and Residential applications are two different animals – EIFS Commercial vs Residential
Applying EIFS to a Commercial building is totally different than applying EIFS to a house. One of the big differences between a building, and a house, when it comes to applying EIFS, is the roof. The roof of a house is completely different from a building. A residential roof line is much more complicated than a flat roof of a typical building. It is common for a roof to terminate right into the side of a wall, which creates a problem for water drainage. Normally the water from the roof runs down the flashing and off the roof into the gutter. This is a good system, until a layer of 1 1/2″ foam is applied to the substrate (OSB) of the house. With the EIFS on the house the water runs down the flashing, and right behind the foam creating major issues. This problem is cured by installing a kick out flashing, which kicks the water past the EIFS, and into the gutter. The roof is probably the most obvious difference, but also the windows and doors are different. Another major difference from a commercial project to a residential project it the contractor. Large corporations build commercial buildings and have a team of architects and engineers that spec and design the project, where as, in a residential project this is usually done on a much smaller scale. Residential projects are open to design, and construction short comings due to the lack of specific industry expertise. This issue travels down to the applicator as well. A large commercial builder has a host of EIFS applicators to choose from that have proven track records, where a local residential builder may not see EIFS often and do not have the access to quality applicators.
Make sure when you hire a contractor to build your EIFS home that they have a proven track record of building and designing with EIFS, and that the applicators that he uses are certified.
EIFS – Exterior Insulation and Finish System – Synthetic Stucco
Welcome to EIFS Repair(1-888-407-2609). If you are interested in the EIFS (Exterior Insulation and Finish System) industry you will find this site engaging and full of knowledge. We have an extensive background in Exterior Insulation and Finish Systems, and have no problem letting you know what we know; As, we feel, that it has been one of the short comings of the entire industry. Keeping the EIFS process a secret has not benefited any one, nor will it. We would rather, a home owner or contractor know the steps needed to complete a professional and successful EIFS project.
That is are aim here at Exterior Insulation and Finish Systems / EIFS Repair, to educate anyone that wants to know about the EIFS industry from general practices, to those little things to look for that Exterior Insulation and Finish Systems applicators just hate to do. Well, I guess it’s not really that they hate to do them, it is, that they are time consuming, and costly. And the little things are very hard to spot unless you really know what you are looking for. But those little things are what can cause havoc down the road.
Here are a few points of interest.

We will not only teach you how to properly do the EIFS application, and what to watch out for, but perhaps the most important part of the site is that we will be introducing new and improved ways of doing EIFS that your applicator may not even be aware of yet. We will do our best to give as detailed instructions and shop drawings of these new techniques our Exterior Insulation and Finish Systems Guru’s come up with here at EIFS repair.
We will also go over the material including specifications and Material Safety Data Sheets (MSDS) and the distributors Dyvit, Senergy and Sto.
