Long bucket life for powder adhesive - Tile Advice

[Wonderfrau]

Would like recommendations for 300 x 600 (x10mm) porcelain tiles, on wall inside a walk-in shower enclosure, tiling directly onto tile backer board.
DIY tiler with limited experience. I think I need a powder adhesive for this size tile, but it needs a long bucket life - had a mare using penny tile Mosaics on the floor, with adhesive skinning before I was ready - even though I only did small sections. What a botched job that was!

How long can I expect a bucket of adhesive to last? Longer than 25 mins would be good :/

Any standard setting adhesive, I always use Tilemaster Standard Setaflex.
Pot life is around 3 hours.

You won’t be disappointed. Make sure and let it slake for about ten minutes.

Thanks for your help guys. The Is Omar was perfect - long bucket life and proper sticky 😃

Pictures of the job attached. Happy with the end result as my errors are not too obvious and the tiles are well spaced. Took me forever and a lot of brainpower to plan it out.
