We have specified PVA coating (same one used for priming gypsum board) to seal sprayed fireproofing in the past in high speed elevator shafts, and rooms that contain electronic equipment, but we're working on a microfabrication lab that includes clean rooms. The lab designer wants us to specifiy a sealer that will not let any particles escape into the air stream.

They mentioned a product called Flame-Mort. Does anyone have any experience with such a sealer?

Vol 10 of 1997 Sweet's had a brochure for Flamort Co., Inc.: 09846/FLM. (Fire-retardant coatings) I have Vol 9 and 11, but no 10, or I would give you their address back then.
4 specs does not list the company, nor does any other current reference that I have.
I suspect they may have been acquired by another producer, and may be listed somewhere as a brand name but not as a producer.
Mark Kalin's firm has been trying to keep track of these name changes, acquisitions, mergers, etc. of late. Perhaps he knows where Flamort has gone.

Actually 4specs had Flamort listed in 07800, and I moved them to 09967.

If you try the blue search box, you will find companies where we do not have them listed as well as a clickable URL for the ones we have. There are about 1,000 companies not yet listed in 4specs in this database. Where we do not have a ULR, we will generally have a phone.

The yellow search box would have returned where they were as well as searching the "Changes" page listing mergers and failures.

My experience with clean room design is that the air systems are ducted supply and return. The only reason I can think to seal the fireproofing is to reduce contamination that may occur during construction. Once the rooms and HVAC systems are complete, fireproofing above a ceiling should not contribute to particles in the airstream or inside the room.
