Has anyone specified these products before? Any words of wisdom? ken hercenberg Senior Member Username: khercenberg Post Number: 503 Registered: 12-2006 Posted on Tuesday, April 23, 2013 - 04:33 pm:    I've heard of it used as an applied fireproofing material but not as a decorative finish. I usually see it as a board product for fireproofing. Whose products are you seeing? After having bad experiences with cast calcium silicate products like Arriscraft, I tend to avoid them. I've never used an applied calcium silicate plaster product on a US project.
