Applications

Typical Applications:

  • 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%.

Surface Preparation:

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:

  • 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

Joint Dimensions:

  • 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.

Remarks:

  • 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.
