As opposed to the niche market of cast epoxy intumescent, thin-film intumescent is a utilitarian solution for the majority of fire protection requirements. It does however have certain drawbacks:
- the successful application of thin-film intumescent paints on site depends entirely on the quality of the subcontractors’ workmanship (and is subject to the time pressures of completing a job on schedule)
- the thicker the coating, the less decorative the finish (resulting in an ‘orange peel’ texture which can seriously undermine the aesthetic value of the system)
- not only is skilled application required, quality and primer compatibility checks are also imperative
- application also requires precautions to be taken against over-spraying
- even if the original application is carried out diligently, the finish is difficult to keep consistent when repairing damage over time
- repair is difficult to hide and normally requires a major part of any column to be re-sprayed
- thin-film intumescent is not particularly suitable for exterior applications (especially very exposed ones)
