The Seattle Children's PlayGarden "Garden House" (building with the green roof in the photo) was built out of ICFs. Both the exterior and interior walls and windows sills are coated with smooth concrete so that the walls look like solid cast-in-place concrete. Any ideas on what coating they might have used? Thanks.

Photo????

Trying to post again.

Concrete with fibers in it sticks well to foam. Shotcrete is the easiest way to apply it.

Here's a link showing a photo: http://www.djc.com/special/concrete2012/awards.html?frmurl=award9.html

Jonr: Thanks. Can the shotcrete finish be where there is very little texture?

There are lots of polymer modified "cementitious" coatings that stick to ICF. Many can be smoothed to look like concrete.

Here is a YouTube video of just one application process.

How do you deal with the exterior product and water issues? Do you still install weep screeds?

The walls I've seen that consist of only foam and concrete/stucco/plaster had no water issues.

Weep screeds are used as a precaution but StuccoMax does not have water issues. It's performance is unmatched with excellent water resistance. There is no efflorescence with StuccoMax as there is with traditional stucco made with sand and mortar. Traditional stucco is a porous material which permits moisture to move both in and out of the wall. StuccoMax does not crack or shrink like others and is much quicker to install also. Let us know if we can provide more info.

So StuccoMax is "waterproof" but the weep screed is installed just in case water gets behind the product?

Does one still need to use chicken wire with StuccoMax?

Any Arizona installs?

StuccoMax is water resistant but water can always get "under" around windows/doors if those areas are not properly installed.
11 oz fiberglass mesh is normally used.
Do not personally know of AZ installs but would think there are.

How does StuccoMax compare to EIFS?
