The Product must be stored in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +5 °C and +30 °C. Always refer to the packaging.

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

Before applying Sika® Ucrete® CR 460 to Sika® Ucrete® P 460 allow the following time:

Note: Times are approximate and will be affected by changing ambient conditions, particularly temperature and relative humidity.

50–80 m of joint per unit

Poor adhesion due to incorrect priming procedure

Incorrectly defined or uncontrolled priming procedures may lead to a variation in Product performance.

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

Poor adhesion due to inadequate surface preparation

Note: Primers are adhesion promoters. Primers cannot replace proper surface preparation and surface cleaning.

Do not use primers for improving poorly prepared or poorly cleaned joint surfaces.

The substrate must be sound, clean, dry and free of contaminants such as dirt, oil, grease, cement laitance, sealant residues and poorly bonded coatings which could affect adhesion of the primer and sealant.

The substrate must be of sufficient strength to withstand 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 dust, loose and friable material from all surfaces before applying the sealant.

Use the following priming or pre-treatment procedures to ensure optimum adhesion and joint durability, or if the Product is used for high-performance applications such as joints on multi-storey buildings, highly stressed joints, or joints exposed to extreme weather.

1. Using a slow speed stirrer, mix the content of the Part A pail for 30 seconds to disperse any separated material.
2. Add the content of the Part B.
3. IMPORTANT Do not mix excessively to minimise air entrainment. Mix the two parts for a further 1–2 minutes.
4. Ensure that no undispersed Part A is left on the side of the pail.

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.

1. After the required substrate preparation, insert a backing rod to the required depth.
2. Apply Sika® Ucrete® P 460 to the substrate using a brush. A thin layer (± 100 μm) should be applied to the joint edges.
3. While the Sika® Ucrete® P 460 is still tacky (30 minutes to 2 hours, depending on the temperature), pour in the mixed Sika® Ucrete® CR 460 to fill the joint flush to the surface. can be applied on angled surfaces up to 2 % without slumping.
4. Refer to the Product Data Sheet of Sika® Ucrete® CR 460 for joint sealant application.

Clean all tools and application equipment immediately after use with Sika® Remover-208. Once cured, hardened material can only be removed mechanically.
