How to stop Sikaflex 221 going off in the tube?

I bought a tube of CT1 to try.

I’ve used it under underseal on occasions, seems to work ok

What colour and what for, clear ct1 reacts and deteriorates in sunlight, black appears to be more stable.

General adhesion duties. First job was bonding wood to the hull for gas support clips. I went for grey as a reminder of what it is. It will not be used externally.

I've had mixed results with bonding small items but out of sunlight is a bonus, tbh it's only the clear I've had self dissolve, it goes back to a semi soft gooey mess
