DWP plywood question(s)

[Sonyman]

Ok, I have just finished laying 3 sheets of the 25mm waterproof ply down on new 5x2 joists, which I treated, and put noggins inbetween first.
My questions:
I noticed that the plywood was a different colour on each side, browny/red one side amd creamy on the other. I have my sheets down with both colours facing upwards, does it matter?

Also, do I have to prepare the ply for tiling with flexible adhesive using PVA on it first?

Thanks

Colour won't matter

Most flexi adhesives will go straight onto ply but check what it says on the bag.

Thanks Jason, I will check what it says on the bag first.
