First post. I have had a search around and answered a few questions, but I have a few more I was hoping people may be able to help me with.
I am tiling my family bathroom. I will be using porcelain tiles that are 30x60 cm on the wall and floors. I am a experienced DIYer and have used porcelain tiles on the floor before, but not on walls or in a bigger room (although this is only 2.3m x 2.4m, so not huge). Planning to use Bal adhesives, but not sure if one adhesive will work for all or if I need two or three different ones!
Start with the floor. It is upstairs, so floorboards which are sound and level. My plan is to overboard with 12mm ply and then use underfloor heating. The heating kit comes with primer. If I use that can I then tile straight over onto the ply and which adhesive?
The walls are more complex! The walls are these preformed platerboard with sort of carboard squares inside. They are not great and there is a little movement in the largest wall. I can see no way to sort this, but the last tiles were on for 30 years and seemed to cope. The wall that moves most will be behind the toliet, so not exactly where people will be leaning on a lot!
So, for the shower area I have aquapanel on wooden studs on one wall. On the other wall I intend to attach aquapanel directly onto the thin wall and screw into the wooden batton inside the wall. Tiling onto the aquapanel, does it matter what adhesive I use and does the aquapanel need priming?
Finally the rest of the walls are plasterboard, a mix of new and old. Does the new need primed and what adhesive? The old has some rips of the top surface and some old adhesive. Does this need primed or sealed? I can't replace this old stuff as it is the internal wall stuff. I don't want to batton and board as we can't really afford to loose 5cm as the room is tight as it is! I have pulled all the board off the outside wall and I will dot and dab new plaster board to that wall.
