It's my first go at tubeless.
I have a DT swiss 533d(22 mm internal) rim which I have taped with gorilla tape (24mm) and have mounted a specialized renegade control.
It pumps up fine but when it loses all the air (I haven't put fluid in it yet so don't expect it to stay up) the tyre bead becomes unseated from the rim.
Do I need to add more tape so that the tyre bead is held securely?
How long does it take to lose the air and the bead come away?
Not necessarily. More tape will make it easier to pump up when unseated but wont make a difference once it is seated. Providing the pressure is suitable and not too low.
Double post.
1. Is the rim TLR
2. Is the tyre TLR
If both yes, inflate, pump up to overpressure (usually 45psi) until you hear 2 loud cracks of each bead seating ( the specially designed bead mating with the channel on a specially designed rim).

Not sure as I have left it overnight.

Yes rim is TLR and tyre is 2bliss

Pumping up to 45PSI but I don't get any loud cracks
Gorilla tape is quite thick.
I have found its great for none-tubeless rims and tyres
However if the rim and tyre are tubeless specific then it means the tolerances are much tighter and the rims have a special platform to securely hold the bead.
I have found with this setup its better to use the Stans tape as its thinner. You need quite a lot of pressure to snap the bead onto the rim and thick gorilla tape can make it harder still and sometimes over stress the tyre bead.
I had one particularly stubborn rim/tyre combination that I eventually managed to seat - as I was preparing to let some air back of the over inflated tyre the bead snapped and the tyre exploded scaring me half to death and covering me in suspicious looking white fluid. I'm pretty sure the thick tape was partially to blame.
Every combination is different but if you are having trouble seating a tyre on a tubeless ready rim I would suggest using thinner tape or fewer layers if you are using gorilla tape.

If its not been seating, try a little water or soapy water on the rim and tyre bead first before you start going above 50psi. It will help it seat.
EDIT hadnt realised it was gorilla tape

Yep with both tyre and rim being TLR you dont want to be using gorilla tape, the tolerances you have wont allow for the thicker tape.

I'm guessing it's not seating properly. You only need the tape to over the spoke holes in the rim. If you've got a 22mm rim and you've used 24mm tape it's presumably wrapped slightly up the sides. It's probably stopping the tyre bead locking into the rim.
Sometimes need significantly higher pressure to get tyres to seat - 60psi or more - then let it back down. to get tyres to seat more easily I spray some silicon spray lube onto a cloth and wipe it round the tyre (less messy than soapy water) but if you're getting it to seal you're most of the way there.
With that combination you really shouldn't need to go over 35 psi to seat the tyre beads. Too much tape?
Are the Tyres control or S-Works ? s-Works have a thinner carcass and can be a pain to get to stay inflated . having said that if you put some sealant in then the tyre will probably be alright given that you got it to go up tubeless and it obviously stayed up for a while .
I had this with Vittoria Voyager tyres on Archetype rims. The tyres would never click to the rim and as soon as they deflated, they couldn't be re-tubelessed without an inflator. It's usually caused by a combination of a slightly baggy tyre with a thin bead on a rim with a hook, but without a shoulder. As the tyre is inflated the bagginess allows it to reach the hook before much stretch (hence no bang/ping) but is still held by pressure and the bead hook. The lack of a shoulder in the rim allows the tyre to fall away from the sidewall when no pressure exists to force it outward and upward.
I ran they for 12000km like this and the only problem I ever had was a vale core coming loose which deflated the tyre and I couldn't re-inflate at the roadside. Tube in and off I pedalled.
