Surface Preparation:

All smooth surfaces can be treated with Soudal Surface Activator. Porous surfaces in water loaded applications should be primed with Soudal Primer 150.

We recommend a preliminary adhesion test on every surface.

Soudaseal Cleanroom has an excellent adhesion on most common substrates, such as the usual building substrates, natural stone, treated wood, PVC and other plastics.

Surface Compatibility:

Soudaseal Cleanroom has been tested on the following Metal Surfaces: Steel, AlMgSi1, Brass, Electrolytic Galvanised Steel, AlCuMg1, Flame Galvanised Steel, AlMg3 and Steel ST1403.

Soudaseal Cleanroom also has a good adhesion on the following Plastic Surfaces: Polystyrene, Polycarbonate (Makrolon®), PVC, ABS, Polyamide, PMMA, Fiberglass Reinforced Epoxy and Polyester.

While producing plastics very often releasing agents, processing aids and other protective agents (like protection foil) are used, these should be removed prior to bonding.

For optimum adhesion the use of Surface Activator is recommended.

Note: Bonding plastics like PMMA (e.g. Plexi® Glass), Polycarbonate (e.g. Makrolon® or Lexan®) in stress loaded applications can give rise to stress cracking and crazing in these substrates. The use of Soudaseal Cleanroom is not recommended in these applications.

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

Application Method:

  • Application Method: With manual or pneumatic caulking gun.

  • Cleaning: Clean with white spirit or Surface Cleaner immediately after use.

  • Finishing: With a soapy solution before skinning.

  • 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 Bonding: 2 mm

  • Maximum Width for Bonding: 10 mm

  • 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.


  • Soudaseal Cleanroom may be overpainted with water based paints, however due to the large number of paints and varnishes available we strongly suggest a compatibility test before application.

  • The drying time of alkyd resin based paints may increase.

  • Soudaseal Cleanroom can be applied to a wide variety of substrates. Due to the fact that specific substrates such as plastics, like polycarbonate, etc, may differ from manufacturer to manufacturer, we recommend preliminary compatibility test.

  • Soudaseal Cleanroom can not be used as a glazing sealant.

  • Not suitable for bonding aquariums.

  • Soudaseal Cleanroom can be used for adhering of and sealing on natural stone.

  • When applying, make sure not to spill any sealant on the surface of materials.

  • 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.
