Need some advise from the experts please. I want to do my tiling project properly once.
I will be using the XPS foam based tile backerboards sold by B&Q. this type in particular: https://www.diy.com/departments/qbo...erboard-h-2400mm-w-600mm/4025345158045_BQ.prd
On all the joints I plan to put tanking tape (i'm thinking to use the ones that have like the elastic stretchy middle with the meshy sides) and apply the joints with the Everbuild Aquaseal Waterproof Tanking Membrane, this one in particular: https://www.amazon.co.uk/Everbuild-EVBAQWPTM-Aquaseal-Waterproof-Membrane/dp/B006FTP6JK from what I understand, i need to first primer the surface with the same brands primer, then apply the aquaseal with a roller or brush and then stick on the tape around all the joints. Then once that's done roll over it with more aquaseal and roll/paint the entire wall over the backerboards so the entire backerboards are covered in the aquaseal at least a few coats of it (so that way everything becomes blue). Then once cured (24hrs later) can start tiling directly on top of this new blue layer? Is this correct method?
My next question and where I am confused is about decoupling membranes. My floor tiles currently are laid on chipboard and i used a oscillating multitool once to do some work in the opposite room and the vibrations made a few floor tiles loose. Now that I am re-tiling the entire bathroom I want to get this right. I understand the proper method is to use decoupling membrane. I plan to replace the chipboard with ply. Do I need to tank the ply with aquaseal first and do the same tape joints like the walls before applying decoupling membrane? Do I not need decoupling membrane on the wall too on the theory that if one surface flexes it doesnt break the tile adhesive etc?
How do you typically install a tile with a decoupling membrane? do you stick the membrane down with something then use tile adhesive like normal?
Sorry for all the questions, I want to get this right first time
Thanks for your time
