EIFS installation process
An overview of the Exterior Insulation and Finish System or EIFS installation process
Exterior Insulation and Finish System / EIFS installation process is as follows:
- Determining which moisture barrier product to use
- Apply eps foam to sub-straight.
- Prep eps foam.
- Embed fiber glass cloth in 1/8 inch thick alpha base coat.
- Apply 100% acrylic polymer finish coat over alpha base coat.
EIFS (Exterior insulation and Finish Systems) also known as synthetic stucco.
That was a quick overview of the EIFS process
Kick out flashing is a very important part of the EIFS install that seems to be over looked by contractors. We have an article explaining kick out flashing including what it is used for and how it should be installed.
Another important aspect of an EIFS installation is a water drainage system which we have covered in depth for you in a separate article as well. The Water Drainage System is very important to get right because if you don’t the substrate of the structure could be damaged if it is not used. We have taken the Water Management System on huge step further with our Water Prevention System.

We have a home in Carrollton, Va built in about 1993. The front part of the house around the dining room, the bedroom above it, the front door and the bathroom above it are all faced with dryvit. These areas are all letting moisture into the framing around the windows and the front door and causing a great deal of wood rot. We are aware that these fixtures need to be replaced but our big question is “what to do about the defective Dryvit?” Should we completly remove all of it or have it repaired? We did not build the house but do know that, other than this problem,the house is extremely well, and custom built. Any ideas and any recommendations of a contractor in our area who might be familiar with this and who is honest and good. Thank you!
The best thing to do when in a situation like this is to cut a piece of the EIFS (Dryvit) right out and take a look back there. What you are looking for first off is if there is a moisture barrier back there over the OSB (wood). You are looking for Tyvke or a rubber like substance that was painted over the wood. If there is a moisture barrier back there it is likely your wood damage is minimal Many times in this situation I find there is damaged area around the windows and were the kick-out flashing was not installed. If this is the case you can usually repair those areas and the problem is solved. When I say fix I mean it has to be done right this time. Sorry to say but it is very possible your contractor will do it the exact same way as the last guy. So, make sure the kick-out flashing is installed and that the base coat is run all the way back to the wood in the window expansion joints around each window. I would recommend educating yourself on how EIFS should be done so you can be sure your EIFS contractor is doing it right. Ask them to give you written details of how they are going to fix it.
Sorry to say I do not have anyone in the area for you to contact.
I hope this has helped and you can always call 586-991-1485
