Intumescent paint UL designs

Hello - I am wondering if you could point me to a couple UL design numbers for a Hilti Intumescent paint. We need to apply the paint to achieve 1 hour protection on an existing steel deck as well as the the roof joists (this can be two different design numbers if needed). Attached is a picture of the existing condition (deck and structure) that we will need to fireproof a portion of. If you have any info on a design number(s) that would work for this it would be much appreciated. Thanks.
