Soudal Transpacryl - Transparent Acrylic Sealant

Soudal Transpacryl is a transparent acrylic polymer based sealant and filler.

Soudal Transpacryl appears white on application but cures transparent. It is solvent-free, virtually odourless and very easy to apply.

Soudal Transpacryl is colourfast and waterproof after curing. It can also be painted over after curing.

Soudal Transpacryl has very good adhesion on many porous surfaces.

Product Benefits:

  • Transparent after curing

  • Very good adhesion on many porous surfaces

  • Good adhesion on anodized aluminium

  • Can be painted over after curing


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.

Typical Applications:

  • Sealing compound for cracks in concrete and plaster

  • Joints with movements up to 15%.

  • Connection joints in the building industry

  • Joints between window sills, between skirting board and floor, between brickwork, etc.


Surface Preparation:

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

Transpacryl is suitable for use on all porous building surfaces, anodized aluminium and ceramic tiles.

Highly porous surfaces should be primed with a suitable primer or with diluted Transpacryl (1 part Transpacryl and 2 parts water).

We recommend a preliminary adhesion test on every surface.

Application Method:

  • Application Method: With Caulking Gun. Tool with Soudaglatt Smoothing Tool for a smooth finish.

  • Cleaning: Clean uncured product with a water immediately after use.

  • Finishing: With a soapy solution before skinning.

  • Repair: With the same material

Joint Dimensions:

  • Minimum Width for Joints: 5 mm

  • Maximum Width for Joints: 10 mm

  • Minimum Depth for Joints: 5 mm

  • Recommendation Sealing Jobs: Joint Width = Joint Depth. Use a PE Backer Rod before applying sealant in large joints to avoid 3-point adhesion.


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

  • Do not apply when rain or frost is imminent

  • Transpacryl can be painted over with most paints.

  • The paint should be sufficiently elastic to be applied on a plasto-elastic sealant. A preliminary test is recommended.

  • Brief contact with water (i.e 24 hours) results in a slight clouding. After prolonged exposure to water (i.e 14 days) the product will turn white again and mechanical properties will reduce.
