Hi guys, I am new to this forum .Me and my partner Ian are renovating a property currently and have some questions about tiling as we are trying to do this between us. The make up of the floor is as follows : dpm / cement / 40-50 cm gap (not much crawling space at the solumn of the house!) / floor joist at about 50 cm centers / treated wooden floors all over the house , 2 cm thick, t&g. We have used hardie backing board of 6 mm directly on the wooden floors. Ian used torque screws. I was hoping that the backing board and screws will stiffen the structure of the floor but no such luck. I can see the floors moving/bending slightly when Ian walks over the hardie board. Should I use ultra or extra flexible tile adhesive in this case ? What would you recommend for such a floor ? I would not like to take a chance, go ahead and tile, and find later that I've used the wrong product. Thanks . Joana
