Hi again
Last week several of you helped me out with advice for a wetroom floor. There were a few different methods, but in the end I decided to go with the following - it's possibly overkill, but I'd rather be safe than sorry (and I'm in the unusual position of not wanting the floor layers to be too thin).
1. 18mm WPB ply
2. 12mm tile backer board
3. Electric underfloor heat mat
4. Latex floor screed
5. Isomat or similar, taped on seams and at walls
6. Tile adhesive
7. 8mm Slate Floor Tiles, washed, dried and sealed
8. Grout
9. Slate Tile sealing solution
I've the ply down, but have few more questions if anyone can help!
Q1. The tile backer board manufacturer says that there should be a layer of tile adhesive between them and the ply. (see here: Multi-Pro MoistSure Fixing Guide - Resistant site - http://www.resistant.co.uk/download/moisture-fixing-information/). Does that make sense with this floor design?
Q2. They suggest priming the boards for tiling with an acrylic based primer on all sides. Do they mean the backs too? And can I miss that step out on the floor as I'm not tiling directly straight on to them?
Q3. They also say to use stainless steel screws, which seems a bit of overkill if I'm putting a layer of isover over the top?
Q4. In terms of the walls, am I OK to just do the following:
a. Studs
b. Tile backer boards (primed on all sides)
c. Tile adhesive
d. Tiles (ordinary 6mm, not the floor slates)
e. Grout and grout sealant
Or do I need a liquid tanking in addition, especially in the shower area?
Thanks again for everyone's help!
