I tend to use no more ply for bathroom floors. The mega strength https://www.tilersforums.com/forums/tile-adhesive/ is quite expensive, I just wondered if anybody else uses flex tile https://www.tilersforums.com/forums/tile-adhesive/ to put this down or any alternative like grip fill??? would this have the same results as no more plys product.
Cheers.
