Firestop ES-105 Elastomeric Adhesive is a highly elastomeric, non-halogenated latex-based caulk that provides passively smoke and fire prevention in building joints

This material can also be used to restore the sound dampening qualities of sound-rated ceilings and walls. The Firestop ES-105 Elastomeric Adhesive is designed to cling to almost any building surface and may be applied with regular caulking tools or troweling. When SpecSeal ES Elastomeric Sealant cures, it forms a flexible barrier against fire spread. Its superior latex binder technology is completely water resistant and won't re-emulsify after drying. There are no inorganic fibers, asbestos, or solvents in SpecSeal ES Elastomeric Sealant. Please get in touch with us. The primary purpose of SpecSeal ES Elastomeric Adhesive is to protect building joints.
