Application guide
Application guide (5 easy steps)
- Joint / Substrate PreparationJoint faces and substrates must be sound, clean, dry and free from dust, oil, grease and loose material. Use a bond breaker / backing rod where required to control joint geometry.
- PrimingApply the appropriate Sika primer to the joint faces where the substrate or service conditions require it, and allow the correct waiting time.
- ApplicationApply the sealant firmly from the cartridge/sausage into the joint, ensuring full contact with the joint faces and avoiding air entrapment.
- ToolingTool the sealant within its skin-over time to a smooth, slightly concave profile that wets both joint faces.
- CuringAllow the sealant to cure undisturbed; protect the joint from contamination and movement until cured.
