Wall prep - this will take a while!

[Boggs]

I always board walls first then fix baths and shower trays to them, sealing the edge with sealant before tiling.

Yes your correct, backing plasters, ie bonding are not suitable for tiling to.

PVA is not a suitable primer for tiling, you should use a SBR or Acrylic primer for this.

If you are using Hardie Backer and you are installing a shower then this will need tanking before tiling as its only moisture resistant.

Hope this helps .
