My question as a new homeowner with EIFS, should I avoid all together
putting any kind of nails or screws in the EIFS for fear it will allow
moisture in. I am thinking of hanging some planters, a piece of
grillwork, and a hose holder. Is there a special way to insert a screw
or nail to prevent introduction of moisture? Thank you.
That is a very good question Joyce, and you are right to that the nail or screw hole will allow moisture and over time can even cause some real problems. What you will need to do first is to get some screws long enough to go through the EIFS system and into the sub-straight. It is important to make sure each screw hole is sealed with silicon caulk. The reason I say silicon caulk is that the silicon caulk will not eat away at the foam like other caulks will.
With that all being said I would like to tell you about a conversation I had the other day with a rep from STO about a cool way to do this process. How it works is that you get some PVC tubing and use it for a mounting bracket. First you will use a drill to cut a hole of the desired diameter and push the piece of PVC with a small amount of adhesive (once again make sure you use a foam friendly adhesive like PL Premium) into the hole making sure the tubing is flush with the EIFS System. Now you can run your screw in your home made hole and fill with caulk. With this system if the nail or screw were to fall out of need to be replace you can simply pull out the caulk and replace it all nice and clean. Having the PVC will help with the heavy things like planters as well you have to keep in mind that there is only foam back there. I really like this idea. I feel this process would work great for filling the holes on store fronts after the side has been removed.
