Has anyone used diall adhesive and grout (combined) or another combined product? I am having a nightmare in that I tiled our shower yesterday, following the instructions carefully, it all seemed okay as the tiles hadn't fallen off in the morning but 24 hours later and it doesn't seem to be setting?? Im hoping that it will dry if left for longer but am worried in case it doesn't set at all at the moment we are trying to manage with no bathroom!! Does anyone else have experience with any of this?? I tiled glass porcelain and marble mosaic (on a mesh) onto a tile backer board......
