[ASKNACHI]This question was posted on AskNACHI.org by Klaus Proehl (from Burnsville, MN). [/ASKNACHI]I currently have 2â€ Styrofoam on the outside of my basement walls, it has been there a little too long. I can take care of the UV damaged areas but with what can I use to fill the holes made by woodpeckers? The second question is? What is a good covering for the foam to protect it from further degradation by UV? Is there a good trowel on or brush on product available? Maybe the question should be; is there a decent book available that covers answers to these seemingly common questions about the use of Styrofoam?
Then rasp it flat.
Cover it with EIFS mesh and basecoat and finish.
I am not saying it is to MFGRS. specs but it will protect it.
If it is where no moisture can get behind it from the top side.
Do you have a couple pictures?
Dryvit system works too.
