Soudal | Intumescent Acrylic Sealant
Firecryl FR is a Fire Rated Intumescent Acrylic Sealant and Filler which is totally free of solvents, silicones and isocyanates.
Firecryl FR is colourfast and waterproof after curing, it can also be painted over once cured. Primerless adhesion on most surface.
Firecryl FR resist the passage of fire and smoke and is fire resistant up to 4 hours with PE backer rod (EN 1366 Part 4-NBN713.020- BS 476/20).
Firecryl FR is intumescent in contact with fire, and swells when exposed to temperatures in excess of 120°C.

Interior Fire Resistant Applications. For exterior applications see Fire Silicone B1 FR.
Fire Resistant sealing compound for cracks in concrete and plaster
Fire Resistant connection joints in the building industry
Fire Resistant joints with movements up to 10%.
Surfaces should be clean, dry, free of dust and grease.
For use on most porous surfaces.
Prepare very porous surfaces such as plasterboard, cellular concrete etc. with a suitable primer or with diluted Firecryl FR (1 part Firecryl FR and 2 parts water).
Not suitable for use on natural stone, bitumen, glass and metal.
We recommend a preliminary adhesion test on every surface.
Application Method: With a manual or pneumatic caulking gun. Finish with spatula or filling knife.
Cleaning: Clean uncured product with a water immediately after use.
Finishing: With a soapy solution or Soudal Finishing Solution before skinning.
Repair: With the same material
Minimum Width for Joints: 5 mm
Maximum Width for Joints: 20 mm
Minimum Depth for Joints: 5 mm
Recommendation Sealing Jobs: Joint Width = Joint Depth. Use PE backer rods in case of large joint dimensions to avoid three-sided adhesion.
Do not use in applications where continuous water immersion is possible.
Do not apply when rain or frost is imminent
Firecryl FR can be painted over with most paints.
The paint should be sufficiently elastic to be applied on a plasto-elastic sealant. A preliminary test is recommended.
