The easiest way is to tap on it, Stucco will sound hard, and EIFS will sound hollow due to its polystyrene foam core.

And just by pushing on it EIFS has a little give stucco does not!

Gerry,

Isn't that hard on the Knuckles? Real stucco will scratsh the tops of your fingernails. EIFS coating won't (Generally).

But you can put an EIFs finish on a hardcoat stucco!
Pull a light fixture and look at the sides of the hole.

[Doug Edwards, CMI]

tap it lightly with the heel end of a screwdriver.

Ask it politely if it is EIFS or Stucco.

[Russel Ray]

What Michael said. And if it refuses to talk, threaten to poke holes in it.

[Carl A. Brown]

With EIFS the control/expansion joints are tooled in groves and or made with backerrod and sealant! The ones in hard coat stucco most af the time are metal! So a little magnet might help you sometimes. But the magnet will not work on zinc. As far as I know the only metal with EIFS is the fastners.

[Dale Duffy]

They very seldom put control joints in EIFS in AZ.

How about casing bead or weepscreed with hard coat stucco?
And corner beads!?

[Dale Duffy]

With EIFS

There is no casing beads or corner beads in Arizona, the entire exterior walls of the building are wrapped with chicken wire and the stucco is applied up to the window frames and soffits...no beads, no control Joints, no backer rods...nippo, zilch, none.

The application is applied/installed like the picture in my previous post.

Except the wood sheathing behind the EIFS.....only at shear walls.

[Dale Duffy]

Frame it....bottom weep flashing...vapor barrier....styrofoam....chicken wire.....stucco.

There is no chicken wire with EIFS! Is it a hybrid!

What would hold the stucco on the building?
