I am planning on building a sealed enclosure for the HiVi SP10 But unsure about how thick the MDF has to be,

If you quickly have a look at the following link, You can see Adam used 1.5 inch for a ported design. I'm designing a sealed enclosure which I'm sure will have to withstand much more pressure.

What thickens should I use? 2 inch all round and braced?

Thanks a lot,
Dan

What type of wood will you be using? I would think 3/4 inch ply minimum, but double up the side that will hold the driver. Also, make sure you brace it well. MDF is not as strong in bending so you can go a bit thicker (MDF is very heavy so keep that in mind) and pay close attention to bracing.
Cheers

I'll use 1" MDF with bracings, with double layer on the front, I think

First audio DIY so any recemended glues, sealants, paints will be very helpful.

"liquid nails" works real good. You can use plain carpenter glue too. Sanding or scuffing up the glue points help quite a bit.
Cheers
