2020Tiling
tiles have cracked along the expantion gap of a floor a tiled a years ago, floor is chipboard over layed with 9mm ply ( i know i used ply but rest of tiles are solid and its taken a lot of effo
rt getting the cracked ones up) primmed rear and edges and staggerd boards with expantion gap . floor had 0 deflection. any ideas ? addy was ultra spf, trowel was solid bed. only thing i can think of is the expantion gap was full of spf instead of silicone< would this be a factor ? ive took some pics for you to look at . thanks.
