SikaSeal® Fire Guard is a high‑performance, one‑part water‑based ablative acoustic sealant designed for maintaining fire integrity in internal joints and penetrations. Engineered to provide up to 4 hours fire resistance, it is ideal for sealing gaps in fire‑rated walls, partitions, door frames, service penetrations, and low‑movement construction joints.
On exposure to heat, the sealant expands by over 150%, forming a protective char barrier that prevents the spread of fire and smoke. It also delivers strong acoustic performance, helping to reduce sound transmission through walls and joints.
Easy to apply and tool, SikaSeal® Fire Guard offers a non‑slump formulation, fast skinning time, and excellent adhesion to most construction substrates without the need for priming. Its flexible properties ensure long‑term durability in fire‑rated applications, making it a reliable choice for professional installers.
