Attaching things to EIFS
Attaching things to EIFS is rocket science but you need to know what to do
I had a lady call me the other day wanting to know the correct way to fasten her hose holder to the outside of her EIFS home. She could not get it to stay on the wall. This is actually a very good question, because there is a very specific way to install things to the outside of EIFS whether it is a hose holder or a down spout for a gutter. First of all you are going to have to use a screw long enough to go through the system. Typically you will have between 1 1/2 inches to 4 inches to go through. You can tell how thick the EIFS is by checking the bottom. The EIFS will stick out from the wall and you can measure it there. You a 3 or 4 inch screw and a 3/8 inch piece of PCV pipe. Drill a hole with a 3/8′s drill bit into the EIFS where you want the screw to go. Stick the PCV pipe in the hole and make a mark where it is flush with the EIFS. Remove the PCV pipe, and cut it on the inside of the line as not to have the pipe stick out past the EIFS, but remain flush with the EIFS. Apply adhesive (PL-Premium, found at your local hardware store) to the outside of the PCV pipe and insert it in the hole you just drilled. The PCV pipe should sit all the way back to the substrate (OSB), and come out flush with the EIFS. It is very important that the pipe is a tight fit, and the adhesive should be around the end that is outward at the EIFS surface to make a good seal. Wipe any excess adhesive away with a damp cloth before it drys. Now, fill the pipe about half way with silicone caulk, and screw your hose to the wall using the holes you just made. When you screw the screw into the pipe excess caulk will come out the PVC pipe again use your damp cloth to remove any excess caulk that gets on the EIFS. That is the old school way of doing it, and of course nowadays you have a fancy new way of doing it, and that would be a Corrosion Resistant Fastener and Sleeve Set. Myself I still use the PVC pipe and it works great, and like I always say if it ain’t broke don’t fix it. If I was doing a large house or building that had down spouts I would however use the Corrosion Resistant Fastener and Sleeve Set’s just to save a ton of time.
Well, there you go, that is the correct way of attaching things to EIFS.
The last thing you want to do is just run screws into your EIFS system, as it will create penetrations that water can enter the system and cause problems down the road.
Have an EIFS Project have someone come out and take a look at it
