"Bituminous Paint: Cold-applied asphalt emulsion complying with ASTM D 1187" is scattered throughout Masterspec and my LEED consultant is concerned with this product meeting the LEED VOC requirements which it probably does not. Does anyone have an idea on how often this product is actually used?
If it is used on the outside of a building it would not matter but on the interior it will be a problem. Is anyone specifying a LEED compatible alternate to bituminous paint? |

I had to switch it out. I used a high build epoxy from Devoe - although everyone has one.
DEVTAR 5A-HS <100g/L and 79% solids
there are others with even more solids and lower VOCs.
I'll bet you dinner Tnemec has one
see description below from cut sheet
A high performance, two-component, chemically-cured high-build epoxy coating for use in areas where coal tar epoxy is normally used. Uniquely formulated to provide corrosion protection for steel and masonry surfaces exposed to water immersion or chemical splash, spillage and fumes. Self-priming on most surfaces. Out performs Coal Tar Epoxies in all respects, including improved recoatability, toxicity, film embrittlement and application properties.
Typical Uses: Ideal for use on underground steel storage tanks,underground steel piping, in sewage and waste water treatment plants, petroleum refineries, chemical plants, pulp and paper mills,fertilizer plants, hydro and fossil fuel power plants, and underground coal & salt mines. Excellent for fresh and salt water immersion in steel and concrete structures on bridges, pilings,basins, and pits. Can be used on concrete block and poured concrete surfaces in commercial and industrial facilities. |

"Bituminous Paint" as we know it has been dropped by SSPC (SSPC-Paint 12)
I currently specify the following which is VOC compliant and since it is manufactured in CA is also CARB & SCAQMD compliant:
Isolation Between Dissimilar Materials:
1.Provide single-component, inert-type non- corrosive compound free of asbestos fibers, sulfur components, and other deleterious impurities; VOC compliant.
2.Elasto-Deck BT as manufactured by Pacific Polymers International, Inc. or equivalent product acceptable to Architect. |

And, depending on what the use is, other kinds of separation can be used--sheet goods and the like.
I have found that in many sections this product is not needed because the materials/products I'm specifying are already coated, and low or no risk of galvanic corrision exists. |

Richard - "or equivalent product acceptable to Architect."...on which day are you talking about? Are they in a good mood or not?? LOL...sorry I couldn't resist!
OK, the serious question now...is the term "Architect" still used in construction contracts in the US? In Canada, due mainly to Canadian Construction Documents Committee (CCDC - a consensus contract developed by private & public Owners, Canadian Construction Association, Royal Architectural Institute of Canada, Association of Consulting Engineering Companies and Construction Specifications Canada) contracts being used pretty much across the country, the defined and acceptable term is "Consultant". Just curious.
Ride it like you stole it!!! |

On a very quick check, I found that Sealmastic emulsion, meeting ASTM D 1187, meets all VOC limits included under LEED limitations. Of course, other ASTM D 1187 products might not, but that would take some investigation. |
