Need help specifying?
Treatment depends on the material, the venue's fire requirements and the application method. Talk to us before you treat a whole build.
Flame retardants reduce flammability; they do not stop materials from burning. Always test on a sample and follow the venue's fire authority requirements and the product data sheet.
