Soudal Stay Fresh Anti Mould Sealant ACETOXY

Soudal Stay Fresh Acetoxy is a Premium Quality, Multi-use, Anti-Mould and Food Safe Silicone Sealant.

Soudal Stay Fresh Acetoxy is a Thick-bodied, 100% Pure Silicone that contains powerful anti-fungicidal and anti-biocidal agents. It has a typical acetic smell on application (similar to vinegar).

Soudal Stay Fresh Acetoxy has primerless adhesion on most traditional sanitary materials, such as ceramic tiles, porcelain, metals and wood.

Soudal Stay Fresh Acetoxy is resistant to UV, rain, snow, ozone and many chemicals. High and low temperature resistant.

Soudal Stay Fresh Acetoxy is not recommended for application onto plastics, such as PVC. Use Soudal Stay Fresh NEUTRAL instead.

Product Benefits:

  • Dual Action - Includes a powerful dual action fungicide and biocide, but is safe enough to use in food preparation areas.

  • Solvent Free - Contains no volatile solvents and does not shrink after use.

  • Lifetime Guarantee against Black Mould Growth

Typical Applications:

  • For sealing shower bases and cubicles, sealing around baths, wet rooms, sinks, basins and any other sanitaryware.

  • For use in kitchens, bathrooms, utility rooms and all areas of high humidity.

  • 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.


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

  • Do not use on natural stones like marble, granite as this may cause staining. Use Soudal Silirub MA for this application.

  • Do not use on polycarbonate.

  • The sanitary formula should not replace regular cleaning of the joint. Excessive contamination, deposits or soap remainigs 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, a white sealant can slightly turn yellow. Under the influence of sunlight it will turn back to its initial colour.

  • We strongly recommend not to apply the Finishing Solution in full sunlight as it will dry very fast in these circumstances.

  • 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.

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

  • Not suitable for bonding aquariums.

  • When using different reactive joint sealants, the first joint sealant must be completely hardened before the next one is applied.

  • Contact with bitumen, tar or other plasticizer releasing materials such as EPDM, neoprene, butyl, etc. is to be avoided since it can give rise to discolouration and loss of adhesion.
