Good advise wanted regarding cement boards

[mike1979]

Hi happy new year to you all I had a look through previous posts but just wanted to clarify a few things I have looked at a bathroom floor that is wooden and it's the plank style so I'm going to use cement boards if I screw the planks down a bit more and make sure there is no squeaks or minimal movements would it be ok then to use the cement boards straight on top and should I use 2 part flex on both sides or can I just use rapid set many thanks

Mike, do as you say but make sure the floor boards are screwed down & there is no bounce then over board with Hardie, glued & screwed.
Hardie state the adhesive is only there as a void filler & to use non flex but I've always used a flexi adhesive for Hardie.
Use the same adhesive to fix boards & tiles.

Ok great thanks thought I'd check so obviously I will screw everything down then it will be ok to serrate rapid set sticky and set the boards into it can I get away with rapid sticky on the boards or should I use flex I only ask as it's a strange one for years I just plod away on site work all new builds

Can you come up to York and sort the floor I've got to replace.

Prime the floor boards with appropriate primer then use a 6mm trowel for sticking the boards down, I walk over the boards then screw them down.
Use 25mm turbo gold screws from ScrewFix.
I always prime the top of the Hardie boards before tiling but you don't have to, it's just a habit I got into.
