I confirmed with SSPC that they discontinued "Paint-12" in 2005. Does anyone know of an inexpensive replacement for this material? The only material I have found so far is Elasto-Deck BT from Pacific Polymers.

Lazar, RA, CCS, CSI, SCIP Senior Member Username: lazarcitec Post Number: 511 Registered: 05-2003 Posted on Tuesday, April 01, 2008 - 03:39 pm:    Richard We spec the following: Bituminous Paint: Cold-applied asphalt coating complying with MIL-C-16173D Type I and Federal Specification TT-C-494B Type II, except containing no asbestos fibers, Karnak 118 Black Asphaltum, manufactured by Karnak Corp. (800) 526-4236; www.karnakcorp.com or approved equal. Apply bituminous paint to properly prepared concealed unpainted surfaces in contact with dissimilar materials. Coat surfaces with 2 coats of bituminous paint for a minimum of 16 mils DFT or as recommended by coating manufacturer. Dipping of aluminum into bituminous paint is not permitted. Allow bituminous paint to dry prior to installation of aluminum component.

Jerome J. Lazar, RA, CCS, CSI, SCIP Senior Member Username: lazarcitec Post Number: 512 Registered: 05-2003 Posted on Tuesday, April 01, 2008 - 11:53 pm:    Phil Currently only 10% of our projects are being specified as LEED Certified. LEED Consultants have told us that for exterior products Bitumen Paint does not need to comply with LEED Certification. I am not sure what you mean by "chemical constitutents"? Several Waterproofing and Glazing Consultants have reviewed our specs with this product specified for aluminum protection and we have never received negative comments. Perhaps you could explain your question further. As a point of note we do not prepare specifications on public sector work, primarily we work in Hospitality and Commercial markets.

Do you happen to know what the VOC content is? In Califormia, it has to be <100 grams/litre as a general rule. Only certain high performance coatings are able to exceed 100g/L Jerome J. Lazar, RA, CCS, CSI, SCIP Senior Member Username: lazarcitec Post Number: 513 Registered: 05-2003 Posted on Wednesday, April 02, 2008 - 12:20 pm:    Richard You need to go to Karnak's website @ www.karnakcorp.com search for "118" and pull up the data sheet, you may also have to call the manuf or email them for that answer. They may have a comparable product to the 118 that is in the same price range and meets your criteria if "118" does not. Our contact at Karnak was: CHRIS HUETTIG (800) 526-4236 #613. Richard L Matteo, AIA, CSI, CCS Senior Member Username: rlmat Post Number: 262 Registered: 10-2003 Posted on Wednesday, April 02, 2008 - 01:50 pm:    VOC content of 118 Black Asphaltum is 395 grams per Liter. Anne Whitacre, FCSI CCS Senior Member Username: awhitacre Post Number: 742 Registered: 07-2002 Posted on Wednesday, April 02, 2008 - 01:55 pm:    Phil: the LEED requirement is for Indoor Air Quality, so the VOCs for exterior coatings aren't as relevant to that, but they ARE relevant to the California Air Quality guys, which is actually more stringent than LEED is. for exterior coatings, its usually the local pollution control authority (wherever you are) that will make a bigger fuss about that. And, there are allowances both for certain types of coatings, and certain percentages of coatings, and certain conditions of coatings. Vivian Volz, RA, CSI, CCS Senior Member Username: vivianvolz Post Number: 104 Registered: 06-2004 Posted on Wednesday, April 02, 2008 - 08:07 pm:    May I repeat the question, and add a criterion: has anyone found an inexpensive, low-VOC replacement product? The Elasto-Deck BT has a low-VOC counterpart, Elasto-Deck BT H2O, http://www.pacpoly.com/membranes/EDsolid100/EDBT100S.pdf. Could someone comment on whether it's suitable for protection of concealed metal surfaces? Tim Werbstein (Unregistered Guest) Unregistered guest Posted on Friday, April 04, 2008 - 10:54 am:    How about ASTM D1187 - Standard Specification for Asphalt-Base Emulsions for Use as Protective Coatings for Metal. Joseph Berchenko Senior Member Username: josephberchenko Post Number: 13 Registered: 08-2003 Posted on Tuesday, April 08, 2008 - 04:09 pm:    I had a Sherwin-William rep recommend the following: "The S-W bituminous coatings are Hi-Mil Sher Tar Epoxy or Targuard Coal tar epoxy. Both are OTC compliant." Cannot personally vouch for either one. John Bunzick, CCS, CCCA, LEED AP Senior Member Username: bunzick Post Number: 879 Registered: 03-2002 Posted on Tuesday, April 08, 2008 - 04:15 pm:    Depending on the specifics, many "paint" products can serve to protect concealed surfaces from corrosion, and likewise--when including sheet materials--to separate to prevent galvanic action between dissimilar metals. I wouldn't worry about it being bituminous paint necessarily. Jerome J. Lazar, RA, CCS, CSI, SCIP Senior Member Username: lazarcitec Post Number: 544 Registered: 05-2003 Posted on Tuesday, April 08, 2008 - 10:53 pm:    Joseph Coal Tar Epoxy has use and handling issues. Fumes mostly. Is it really VOC compliant? Joseph Berchenko Senior Member Username: josephberchenko Post Number: 14 Registered: 08-2003 Posted on Wednesday, April 09, 2008 - 03:05 pm:    I can't vouch for it being VOC compliant. I had asked the S-W rep if he still sells bituminous coatings and what he recommended for metal protection. The subject came up because 1) I'd heard from architects that they are not getting bituminous coatings when they call for it, but instead are getting painted surfaces like John mentions above; 2) SDI Technical Data Series Industry Alert 127J "Bituminous Back Coating of Frames" in which SDI seems to discourage back coating saying that bituminous coating is an "archaic term" and "it is not readily available," http://www.steeldoor.org/res/SDI_Series-IndustryAlerts.pdf ; and 3) the SSPC issue. The S-W rep acted like it was not archaic and still readily available and frequently used. Would like to hear more on this topic from this group as to whether it's seen in the field and whether they feel paint (say minimum 15 mils DFT) is adequate corrosion protection for metal in lieu of bituminous coating. Vivian Volz, RA, CSI, CCS Senior Member Username: vivianvolz Post Number: 105 Registered: 06-2004 Posted on Wednesday, April 09, 2008 - 03:54 pm:    The Pacific Polymers people contacted me, quizzed me extensively, and suggested their Elasto-Mulsion A300, http://www.pacpoly.com/membranes/EMA300/EMA300.pdf, which is a waterborne asphalt emulsion. Kim Grosch, with her colleague Stephan Claus, wrote: "Elasto-Emulsion A-300 can be used for damp-proofing above or below grade foundation walls, sealing masonry surfaces and retaining walls and as an Anti-corrosive wood, metal, and pipe coating. Elasto-Emulsion A-300 is non-flammable, odorless and bonds to damp or dry surfaces." I have not evaluated the product myself; I'm just passing along what Pacific Polymers offered. I welcome feedback.

Lazar, RA, CCS, CSI, SCIP Senior Member Username: lazarcitec Post Number: 545 Registered: 05-2003 Posted on Wednesday, April 09, 2008 - 03:59 pm:    Joseph We provide the following in Part 2 of the appropriate spec sections: "Apply bituminous paint to properly prepared concealed unpainted surfaces in contact with dissimilar materials. Coat surfaces with 2 coats of bituminous paint for a minimum of 16 mils DFT or as recommended by coating manufacturer. Dipping of aluminum into bituminous paint is not permitted. Allow bituminous paint to dry prior to installation of aluminum component." and the following in Part 3: "Confirm that unfinished concealed aluminum in contact with dissimilar metals, cementitious materials, masonry, and wood has been treated with a protective coating as specified in Part 2 of this specification section."
