Need to seal plywood subfloor?

[lmsava]

I've just overlaid the floorboards in my bathroom in preparation for vinyl floor tiles. The instructions on the packs of the tiles say that I should seal the ply but I've read on here that I don't need to seal WBP. There's no helpline on the tile packs that I can call to get a recommended sealing product so what would be the best thing to do? I thought about using PVA but that doesn't seem suitable for a bathroom. If I don't seal, will the ply just soak in the floor tile adhesive?

While I'm wirting, can anyone recommend a good adhesive for vinyl floor tiles?
