Uses
Sikasil®-129 Kitchen & Bathroom is designed for sanitary and other sealing applications that require mildew resistance.
• Wet areas.
• Internal and external.
• Multi substrate: metal (not including copper), glass, stone, aluminium, and plastic.
Strictly follow installation procedures as defined in method statements, application manuals and working instructions which must always be adjusted to the actual site conditions.
Masking
• It is recommended to use masking tape where neat or exact joint lines are required. Remove the tape within the skinning time after finishing.
Joint Backing
Priming
• If required, prime the joint surfaces as recommended in substrate preparation. Avoid excessive application of primer to avoid puddles at the base of the joint.
Application
• Sikasil®-129 Kitchen & Bathroom is supplied ready to use.
• Prepare the end of the foil pack or cartridge, insert into the sealant gun and fit the nozzle. Extrude Sikasil®-129 Kitchen & Bathroom into the joint ensuring that it comes into full contact with the sides of the joint.
• Avoid any air entrapment.
Finishing
• Immediately after application, sealant must be firmly tooled against the joint sides to ensure adequate adhesion and a smooth finish.
Use a compatible tooling agent to smooth the joint surface. Water can be used. Do not use tooling products containing solvents.
Important Considerations
▪ Do not use on alkaline surfaces such as concrete, plaster and masonry.
▪ Sikasil®-129 Kitchen & Bathroom cannot be overpainted.
▪ Colour variations may occur due to exposure in service to chemicals, high temperatures and/or UV-light (especially with white colour shade). This effect is aesthetic and does not adversely influence the technical performance or durability of the product.
▪ Do not use on bituminous substrates, natural rubber, EPDM rubber or on any building materials which might leach oils, plasticisers or solvents that could degrade the sealant.
▪ Do not use Sikasil®-129 Kitchen & Bathroom in totally confined spaces as it requires moisture from the atmosphere to cure.
▪ Do not use to seal joints in and around swimming pools.
▪ Sikasil®-129 Kitchen & Bathroom is not recommended for porous substrates such as natural stone, marble and granite. Bleeding can occur when product is used on these substrates.
▪ Do not use where physical or abrasive exposure is likely to occur, structural glazing and insulated glazing or food contact applications. Contact Sika Technical Services for advice on alternative products.
▪ Do not use for joints under water pressure or permanent water immersion.
▪ Do not use for medical or pharmaceutical applications.
