SikaSeal®-173

Bitumen based, reinforced with cellulose fibres

15 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 the packaging.

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

The substrate temperature must be +3 °C above dew point temperature and free from frost and ice.

IMPORTANT

Poor adhesion due to inadequate substrate preparation

1. Test the adhesion on a project-specific substrate.
2. Agree on the substrate preparation procedure with all parties before full project application.
3. Contact Sika Technical Services for additional information.

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. Cut the end off the threaded stub on cartridge, screw on nozzle and cut nozzle to desired bead size at a 45° angle.
2. Insert the cartridge into the application gun.
3. Apply the SikaSeal®-173 into the joint. Note! Avoid air entrapment. Make sure that the SikaSeal®-173 comes into full contact with the adhesion area of the joint.
4. 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. 
5. It is recommended to use masking tape where exact joint lines or neat lines are required. Remove the tape within the skin time. Do not use tooling products containing solvents.

BONDING APPLICATIONS

1. Apply SikaSeal®-173 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.
