What silicone to set a Mira shower tray on?

[RichD1]

Got a Mira Flight shower tray which says can be siliconed to the floor. The current floorboards are pretty flat and well secured down with no movement anywhere. The tray does need about a 5mm packer under one corner to get it perfectly flat so what is the best silicone to use which will go off reasonable solid to take up the small gaps across the floor and support the tray.

I had looked at removing the floorboards to replace with a square of ply but the boards are so good and there are only small gaps to make it level with the current boards.

Cheapest you can buy!
4-5 tubes of it

Does it need to high or low modulus?

I would assume high as this is less flexible therefore providing more support to the tray.

As long as you use a decent silicone between the tray and the tiles it doesn't matter!

785 is my poison around tray and screen... under tray is whatever I can get cheap!
