Thank you! It was not difficult to butt the tiles tightly against one another. The glue was very cooperative: it was tacky, and not slippery, so once the tiles were in place and we rolled the surface, the tiles did not budge or slide around – they stuck firmly in place as we worked. As an alternative, you can space this tile like you would a ceramic tile and then grout it. Here is my step by step tutorial for how to install the flooring: DIY Luxury Vinyl Tile Installation.
