Metacaulk 1000

Quick Overview

Metacaulk 1000 is a general-use, single-component, intumescent sealant and smoke seal for construction joints & through-penetrations. Cures to elastomeric seal suited to dynamic motion. Metacaulk 1000 expands when exposed to heat, creating a refractory char that effectively seals and prevents the spread of flames, smoke, and toxic fumes. This product boasts a 3-year shelf life and excellent freeze-thaw stability. Its non-sag, flexible curing process results in an elastomeric seal, ideal for applications with dynamic movement. Designed for versatile interior use, this water-based sealant requires no mixing or dilution and is paintable. It is protected against mold growth in both wet and dry stages with a combination of biocides. Safe and easy to use for most applications, including retrofit, it can be applied using a conventional caulking gun, bulk loading gun, troweled from a pail, or pumped directly from a pail. Additionally, it is compatible with FBC Systems.
