I was just wondering what the purpose of the WBP ply is when doing floor tiling in the bathroom? Is it to make it completely flat or to spread load across floorboards or to ensure that none of the individual floorboards move under the tile?
I'm asking because we've laid the ply and in a couple of places where the edges meet up there is a small difference in height. This is most noticeable when you rest a tile on hte ply across gaps, basically the tile can wobble a bit and i'm wondering if we need to sort this out in some way?
