  • Can be used to seal door and window frames internally in areas subject to high condensation.


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 Caulking Gun.

  • Cleaning: Clean with a Surface Cleaner immediately after use.

  • Finishing: With a soapy solution before skinning. Tool sealant with Soudaglatt Smoothing Tool for a smooth finish.

  • Repair: With the same material


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.


  • 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.

  • 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.
