Siderise FR-A Fire Rated Acrylic Sealant - 310ml Tube

310ml Siderise FR-A Fire Rated Acrylic Sealant is a single-part, intumescent acrylic mastic specifically engineered to provide effective fire stopping for linear gap seals and service penetrations in various construction elements. Designed for both new build and refurbishment projects, this sealant is a crucial component in maintaining the fire integrity of buildings. Upon exposure to fire, the Siderise FR-A sealant expands (intumesces) to form a robust, insulating char. This char effectively seals the gap or penetration, preventing the passage of flames, smoke, and hot gases for a specified period, thus helping to compartmentalise fire and protect escape routes. Siderise FR-A Acrylic sealant offers excellent adhesion to a wide range of common building materials, including concrete, masonry, steel, and timber. It is easy to apply directly from the tube using a standard mastic gun, providing a clean and efficient installation process. Once cured, the sealant remains flexible, accommodating minor movement within the building structure. It is paintable once dry, allowing for seamless integration with the surrounding décor. It is an essential product for ensuring compliance with stringent fire safety regulations in walls, floors, and around services such as pipes and cables, providing peace of mind and contributing to overall building safety.
