I see this called Direct-Applied Finish System (DAFS) or Direct-Exterior Finish System (DEFS) - but never just Cement-Board Stucco (CBS ?! or just EFS in lieu of EIFS). STO's own recommended guide-spec places this as a Division-07 product, in the same general area as EIFS which it replaces, but there is really no "insulation" in the assembly as I believe that placement originally intended. To me, it is really a "cement-plaster" or stucco replacement, as a "wall-finish treatment" - meaning it should be a Division-09 specification (generally in the "plaster" area). Any thoughts from the experts out there? Should I have purchased the possibly more complete updated MasterFormat instead of using the original web-available free version?

We call it Direct Applied Finish System. I'm guessing you're from Florida, as that's the only place I ever heard the term CBS (cement block stucco). Do other regions use that term and building technique as well?

Either way, it may be worthwhile to write a separate section for it so that it does not get lost. It will thus appear in the project manual table of contents. I think as long as participants can find the information with reasonable effort, we have done our job well. Jerome J.

In Florida, we have had success with Dryvit's version, though STO makes an excellent product as well.

If it were going to always be in Florida, Texas or Southern CA, we might design concrete-block stucco w/ 200 feet of un-interrupted walls without control-joints like they do down in Mexico that our client's always see and want us to design! (But wouldn't that then be called: CMUS for Concrete-Masonry-Unit Stucco - CBS was an off-handed reference to a TV network!). I'm tending to think we should use the terminology on Drawings & Specs referenced to Div-7 (in our Keynotes and spec title) as EFS - for "Exterior Finish System" (I'm sure "direct" means that the finish is directly applied without the insulation layer, but why complicate terminology). That keeps it in the same generic ballpark as the EIFS systems - just without the "I" for the insulation. I wonder if DEFS or DAFS is intended to remove any bad-association with EIFS, for the P & Z, insurance, or code folks that "fear" it.

That made it easy to decide to stick with DIV 9 and call it 09210 or 09 24 10 (we stick with round numbers). Regarding EIFS, we have gone with the flow and put it in DIV 7, but I have always thought that was less than perfect. We have never had a job where the insulation was really being used as insualtion instead of simply a cheap inert furring material.
