Introduction
Flame Seal 84 (FS84) is a water-based Intumescent paint that can be applied to most substrates including, lumber, plywood, OSB, and Gypsum. FS84 is fully tested and has a rating ranging from Class A to 30 minutes to meet building codes domestically, internationally, and for the Wildfire Urban Interface. When Flame Seal 84 is exposed to fire or extreme heat, a protective layer of Carbon Foam develops and prevents the fire and heat from transferring to the substrate. FS84 is a low VOC fire retardant paint with a smooth white architectural grade finish. This product can be paired a primer and a top-coat. For best application Flame Seal recommends using an airless sprayer, please see application guide for more information.
