summer wine

Fairly limited instructions, not specific to our size of tray. Just said 5:1 sand & cement or silicone, but because of the size of our tray, other half was dubious about just silicone because that could only be put on the high points. His main worry is that the cement will find its way into all the voids. He knows about sealing the ply, (planning to use waterproof pva), but, just out of curiosity, does sealing it help the cement stick to it or is it just for waterproofing?
I'm beginning to think the old bathroom wasn't so bad after all!
