Contego, like other intumescent coatings, is latex based. While Contego can be applied over an existing finish, you need to know what it is. If alkyd, or if you just don’t know, do an adhesion test. If the existing finish is good, apply a bonding primer before applying Contego. If you’re unsure, it’s better (and a lot less expensive) to apply a bonding primer and not need it than skipping that step and wishing you hadn’t.
Here’s an article from “Durability + Design” on the subject that we found particularly useful:

Contego fire resistant paint has been chosen by Saudi Arabia Railway to protect its railway stations.
The SAR (Saudi Arabia Railway) project will include both passenger and cargo railway systems. The passenger service utilizing advanced modern trains will start in 2014 and will have six stations in Riyadh, Majma’a, Qassim, Hail, Al-Jawf, and Al-Qurayyat. All of the stations have been protected by Contego intumescent paint.
