Hello, We have built a new Ambulatory Surgery Center and the contractors have filled the firewall penetrations with drywall mud. I am wanting them to redo it with "Fire Sealant" (Red/Yellow). They are stating that the white mud is fire rated. I have seen several "opinions" but can't seem to find if, in fact, this drywall mud is an acceptable seal around all the penetrations?
Would appreciate any advice on this.
