Nelson™ Firestop Putty (FSP™) is a completely premixed and ready-to-use firestop product that can be hand pressed into place forming an immediate fire seal. When exposed to fire the putty material forms a hard char that creates a formidable barrier to smoke and flame. FSP™ is a blend of organic and inorganic materials that is hand moldable. FSP™ is reusable when adding or changing penetrating items since the material remains pliable and does not set up.
