Seems like I've had a lot of temporary banner installations on Drivit lately - the stucco type foam construction material a lot of shopping centers are using now. Screws don't really grab and I don't want to put huge holes in it for anchors or molly bolts, especially since most of these installations are short term and lightweight.
Anybody know of any magic fasteners?

we have done few banners and large signs on drivit walls. We just use a long screw (deck screw)so that we get to the OSB sheet behind the stucco and foam. Only good for banners...larger signs we would never use just screws. Toggle bolts and for much larger projects. Bolts with angle on back side of the wall spanning the studs.

Long GRK screws here too Sonny,...Add a large fender washer behind the banner first and it gives great strength without any crushing to the eps foam.

Sonny,
Demand products has lots of products for Drivit installation. Shop there to get an idea of hat to look for locally. www.demandproducts.com Posted by Rick Chavez (Member # 2146) on :
I call out a long screw with a sleeve slightly longer then the depth of the Drivit wall and screw into the backing sheet That way you can't over-tighten and damage the Drivit wall...

In the Demand Products catalog is an Auger Anchor for attachment of relatively lightweight things to EIFS. I have used drywall anchors with marginal success. The Auger Anchor is similar, but much wider.
I haven't tried it yet but I plan to.

Sonny, We've had 90 MPH winds here today and I've seen banners & billboard bags down all over town. When I draw attachment details for dryvit, it's always toggle bolts clear thru the plywood backer. It's not as windy in Atlanta, but be carefull bro... make sure you're grabbing on to something solid.

I've used the auger type anchors sucessfully

Great responses - thank you all.......

Sonny, have you thought about an adhesive system, then there's no holes going into the material at all!
Any time you put a hole through that stuff you're asking for water to come in and start undermining it.

Mike,
How do you hold the panel or letter in place with an adhesive sets up?
I have a couple of lines of 4" brass letters to install on a Drivit surface.

Sonny, I've heard that new Gorilla Duct Tape is really tough stuff that will stick to anything. 2 or 3 runs of that tape around the outside of the banner should hold it pretty good. I think, since you are in Georgia, you might could even charge extra for using a 'premium' mounting system.

Joe,
I would think that 4" brass letters wouldn't weigh so much that they couldn't be supported by studs until the adhesive sets up.

I've had good luck with the drywall anchors. I put a little dab of liquid nails on the threaded part of the anchor and just twist it in. In an hour or two, the glue is set up, and it makes a pretty solid fastener.
It's easy to put a dab of exterior spackling over and touch up when you take it down too.

Joe,
Either VHB (very high bond) tape, or use the new breed of urethane adhesives that are applied with a mixing gun and setup in 60 seconds.
When I worked in the skyscraper field developing the exterior window systems, VHB tape and 2 part structural silicone was the preferred method of installing the glass onto the aluminum framing when there were no visible fasteners allowed and minimal sight lines were required.
