We have a project that has double plaster boards finish that equates to 30 minute fire retardant finish, but the client want 60 minute, is there a paint that can be applied to bring the board up to a 60 minute without removing the boards
Assuming the substrate meets the requirements stated in the Technical Data Sheet and approval is sought from building control prior to application we can recommend Thermoguard Wallcoat 30 & 60 Minute System.
