Areas for Use

Soudal Silirub® 2/S is used for sealing Sanitary, Construction and Industrial applications where food contact is required.

Soudal Silirub® 2/S can also be used for the sealing of containers, cold-storage, air-conditioning, bathrooms, kitchens and other areas prone to high humidity.

Surface Preparation:

Surfaces should be clean, dry, free of dust and grease.

Porous surfaces in water loaded applications should be primed with Soudal Primer 150. No primer needed for non-porous substrates.

There is no adhesion on PE, PP, PTFE (Teflon®) and bituminous substrates. We recommend a preliminary compatibility test.

Application Method:

  • Application Method: With a manual or pneumatic caulking gun.

  • Cleaning: Clean with a Surface Cleaner 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: 30 mm

  • Minimum Depth for Joints: 5 mm

  • Recommendation Sealing Jobs: Joint Width = 2 x Joint Depth.


  • Do not use on natural stones like marble, granite etc. as it may cause staining.

  • Do not use on polycarbonate. Use Silirub® AL2T instead.

  • The sanitary formula should not replace regular cleaning of the joint. Excessive contamination, deposits or soap remainings will stimulate the development of fungi.

  • A total absence of UV can cause a colour change of the sealant.

  • In an acid environment or in a dark room, white silicone can slightly turn yellow. Under the influence of sunlight it will turn back to its initial colour.

  • We strongly recommend not to apply the product in full sunlight as it will dry very fast.

  • When finished with a finishing solution or soapy solution, make sure that the surfaces are not touched by this solution. This will cause the sealant not to adhere to that surface. Therefore we recommend to only dip the finishing tool in this solution.

  • Do not use in applications where continuous water immersion is possible.
