With Soudal Soudagum fr 8L, you create a dependable and effective firestop seal around penetrations and metal pipes. This ready-to-use intumescent acrylic paint and sealing paste expands at temperatures above 180°C to automatically close gaps, preventing the spread of flames and toxic smoke gases between compartments. You can easily apply it at ambient temperatures between 5°C and 30°C to clean substrates such as concrete, masonry, wood, and metal. Once fully cured, the water-resistant white surface remains neatly in place and is fully paintable with common paint systems for a clean finish.
