Hi,
I have just finished preparing my bathroom for tiling.
I have bought 17.5Kg/m2 tiles (32x45cm) and I have Mapei Keraflex maxi cement. Around the shower area I have Aquaboard fixed to studs and I also have some areas of plasterboard fixed to studs. Both of these should be OK from what I read.
The problem is one particular wall (not a wet wall) where I have a mixture of bare bonding plaster and skimmed plaster. This is because a lot of the previous skim came off with the (smallish) tiles and also a lot of the previous bonding.
I asked the plasterer to make the wall "flat for tiling" and he made the level up to the remaining skim coat with bonding.
I am now aware from reading this forum that my tiles + cement + grout push just over the 20Kg limit for Gypsum (putting aside any concerns over whether I should even tile on the bonding at all).
So to get to the point of this post, I'm now considering my options, some ideas I've had:
1. Rip it all off and dab platerboard to it (not appealing)
2. Just tile on it and take the risk. Surely 20Kg is a conservative figure. What's the worst that could happen?
3. 9mm Plasterboard covering, but not sure how to fix through the plaster to the wall.
4. 9mm Backerboard or plywood etc with something like frame fixings through the plaster to the wall.
Has anybody else got any other ideas or advice?
Many thanks,
Rob.
