    What side of WBP ply do I tile onto please?

    Hi folks, What side of WBP ply should I tile onto? Smooth side or rough side? Does the side I'm not tiling onto need a primer? Thanks all Mart

    18mm WBP ply prior to tiling

    I’ve bought 18mm WBP ply for the bathroom to fix directly to the joists and got noggins every 400mm. Is this base ok to tile onto with flexible adhesive and grout? It’s having electric UFH too. The reason I went for 18mm is because it’s 18mm floorboards running to it at the door threshold. Thanks
