12 months from date of production

The Product must be stored in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +5 °C and +25 °C. Always refer to packaging.

Refer to the current Safety Data Sheet for information on safe handling and storage.

Beware of condensation. Substrate temperature during application must be at least +3 °C above dew point.

Poor adhesion due to inadequate substrate testing

Note: Test adhesion on project-specific substrates and agree on procedures with all parties before full project application. For more information contact Sika Technical Services.

The substrate must be sound, clean and free of all contaminants such as dirt, oil, grease, old sealants and poorly bonded paint coatings which could affect adhesion of the sealant.

The substrate must be of sufficient strength to resist the stresses induced by the sealant during movement.

If tested, or supported by experience, the Product can be used without primers or activators on a wide variety of construction substrates.

1. Use techniques such as wire brushing, grinding, grit blasting or other suitable mechanical tools to remove all weak substrate material.
2. Completely remove all dust, loose and friable material from all surfaces before application of the sealant.

IMPORTANT

Strictly follow installation procedures

Strictly follow installation procedures as defined in Method Statements, application manuals and working instructions which must always be adjusted to the actual site conditions.

IMPORTANT

Absorbency of natural stone substrates

Staining from plasticiser migration may occur when used on natural stone such as granite, marble or limestone substrates.

1. Carry out preliminary trials before full project application.
2. Contact Sika Technical Services for further advice.

SEALING APPLICATIONS

1. Open the seal on the top of the cartridge or open the end of the foil pack.
2. Fit the nozzle and cut it to the desired bead size.
3. Insert the Product into the application gun.
4. Apply the Product into the joint. Note Avoid air entrapment. Make sure that the Product comes into full contact with the adhesion area of the joint.
5. As soon as possible after application, use a suitable tool such as a spatula to smooth the sealant firmly against the joint sides to ensure adequate adhesion and a smooth finish.

BONDING APPLICATIONS

1. Apply the Product to the surface of the component to be bonded and then press it onto the substrate.
2. If necessary, use temporary adhesive tapes and spacers to hold the assembled components together during the initial curing time and ensure the desired bond line thickness.

Clean all tools and application equipment with a cleaning agent such as acetone or white spirit immediately after use. Hardened material can only be removed mechanically.
