Ok I am re-tiling the kitchen floor due to me not doing it properly first time ! I tiled it approx 18 months ago . Tiled onto a chipboard floating floor no flex adhesive ( yes I am a numpty ) surprisingly the tiles lifted and grout cracked !! . I have lifted all the tiles and cleaned floor then I have taken up the floor drilled plugged and screwed 10mm battens to concrete base floor then screwed floor sheets (22mm)to battens at 250mm centers . I have jumped up and down on floor and its solid no lift or flex. I have 600mm tiles to fix . What adhesive should I use to fix tiles ? Should I use a primer on floor ? I have tried to clean the existing floor the best I can . Was thinking about Mapei flexible . Do I need an admix also . What grout should I use also . Cheers all just want to do the best job I can
