Installation Video
Protecta FR Acrylic is a versatile firestop sealant designed to prevent the spread of fire, smoke, and toxic gases through joints and service penetrations in fire-rated walls and floors. It also helps maintain acoustic performance and airtightness within the building envelope.
This water-based sealant cures on exposure to air, forming a durable and slightly flexible joint capable of accommodating minor structural movement over time. In the event of a fire, FR Acrylic intumesces—expanding at approximately 180 °C, to create a robust barrier that effectively blocks flames and smoke.
Typical Applications
- Sealing around pipes and cables in walls and floors
- Firestopping perimeter gaps and linear joints
- Ideal for hospitals, schools, apartments, offices, and other commercial or residential buildings
FR Acrylic can be applied directly or used in combination with a suitable backing material to ensure correct joint depth and minimise shrinkage during curing. Depending on the application and dimensions, it provides up to 4 hours of documented fire resistance.
