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.

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

The substrate must be clean, dry, sound and homogeneous, free from oils, grease, dust and loose or friable particles. Cement laitance must be removed.

The substrate must be sound, clean, dry and free of all contaminants such as dirt, oil, grease, cement laitance,
old sealants and poorly bonded coatings which could affect adhesion of the primer and sealant. The substrate should be of sufficient strength to withstand with the stress induced by the sealant during movement.

Use techniques such as wire brushing, grinding, grit blasting or other suitable mechanical methods to remove all weak substrate material. Repair all damaged joint edges with suitable Sika® repair products. Remove all dust, loose and friable material from all surfaces before application activators, primers or sealant.

Where joints in the substrate are saw cut, after saw cutting, all slurry material must be flushed away and joint surfaces allowed to dry.

Clean all tools and application equipment immediately after use. Once cured, residual material can only be removed mechanically.
