Troubleshooting
Sealant is not adhering to the surface.
Ensure the substrate is clean, dry, and free from dust, grease, or any release agents. Check if a primer is required for the specific substrate (though generally not needed).
Sealant is sagging or slumping.
Verify that the joint width does not exceed the maximum 50mm. Ensure the sealant is applied evenly and tooled correctly.
Sealant is not curing properly.
Check storage conditions; extreme temperatures can affect curing. Ensure adequate ventilation and that the ambient temperature is within the recommended application range.
Surface is difficult to tool.
Tool the sealant immediately after application while it is still wet. Use a damp tool or spatula dipped in soapy water for a smoother finish.
