Hi Rob
It is not normally too difficult to squeeze out of the tube,
Can be a bit of a task if you cut too small a bead on the nozzle or have not pierced the top large enough
The usual cosistency is not a lot thicker than silicone sealant, may be well worth checking that you have not got a small blockage somewhere ?
There could be an outside chance that you have been sold some really old stock, it will start to set in a sealed tube over a long period of time
I hope you get it sorted mate .... Nice to see you making progress
