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

Application Method:

  • Application Method: With a Caulking Gun.

Coverage of any sealant product varies depending on Joint Width and Joint Depth.

Please refer to our Guide on How To Measure The Number of Tubes Required For the Job.

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.


  • Because of the acid nature, certain metals (eg copper, lead) can be affected.

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

  • Direct contact with the secondary sealing of insulating glass units (insulation) and the PVB-film of safety glass must be avoided.

  • The sanitary formula should not replace regular cleaning of the joint. Excessive contamination, deposits or soap remaining's 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.

  • 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.

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

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

  • Do not use on polycarbonate. Use Soudal Aquafix instead.
