Application Instructions


  1. Read the Safety Data Sheet before use and use the recommended personal protective equipment.
  2. Remove all loose debris, any contaminants such as grease and oil from the surfaces to be sealed.
  3. Moisture is necessary to ensure a fast and even curing of the foam. Spray surfaces with water to moisten them when foam is applied (a spray bottle for plants can be used). This is especially important in warm and dry areas.
  4. The tin must be shaken well 15-20 times before use. Attach the gun to the tin but do not overtighten or activate the release valve.
  5. The tin should be turned upside down for foam application so that the gun is under the tin.
  6. Depending on the joint orientation and size, best results will be obtained by building up multiple layers from the bottom, thus allowing each individual layer to part cure. Do not attempt to insert excessive wet foam as rapid expansion will cause wasteful overspill of curing foam in the joint and may apply pressure to soft materials and push them out of position. Foam extrusion can be controlled by depressing the trigger on the gun more or less or reducing the pressure on the valve.
  7. Once the gap or joint is completely filled, excessive overspill should be removed by cutting with a knife or similar.
  8. After sealing the foam should be covered by a substrate resistant to mechanical damage and UV-radiation.

Fire Classification

Sealing masonry or concrete walls ≥ 150MM

Joint type (Max width) Installation (Min seal depth) Joint type Classification
Horizontal joint ≤ 20mm Single sided ≥ 150mm (1) EI 180-H-X-F-W 20
Horizontal joint ≤ 20mm Single sided ≥ 140mm (2) EI 240-H-X-F-W 20
Vertical joint ≤ 20mm Single sided ≥ 150mm (1) EI 60-V-X-F-W 20
Vertical joint ≤ 20mm Single sided ≥ 140mm (2) EI 240-V-X-F-W 20

  1. The FR Foam should be covered or painted on both sides
  2. The FR Foam must be covered on both sides with ≥ 5mm IPT

Sound Insulation

Description Sound reduction
Single sided seal ≥ 50mm depth & ≤ 30mm width 61 dB RW

Same or higher sound reduction will be achieved with greater depth, double sided or with backing material. The sound insulation value is only valid for the foam and not for other elements in the building construction. The sound insulation has been tested by the accredited laboratory BM Trada in Great Britain according to EN ISO 10140-2. Test report is available upon request.
