Tiling Dilemma

[mika_98]

Hello all,

I seem to be in a dilemma with the tiler and tiling my bathroom. First of all, things to bear in mind are that the walls are slightly damp and I have gone for porcelain tiles. The walls have been treated with a damp proof course but I have been advised any previous damp may remain for a while.

With that in mind, I'm assuming the best method is to fit a board of some sort to tile onto. If that is correct, which method should I use - dot and dab with adhesive or studwork?

I'd rather go with the dot/dab as my bathroom is very small (1.8 x 1.5m). Batons plus boards, followed by tiles will take up what little space I already have. If I go down this route, which boards (apart from plaster/MR) can I fit using adhesive? I'd love to use something like Aquapanels but was advised they have to be fitted using batons. Are there any other alternatives?

However, if its best to go with batons+boards, which combination can I go with (again apart from plaster/MR) that will take up less space? Aquapanels I believe require a 38mm baton according to the manufacturer!

Also, I've never heard of this but the tiler wishes to add some kind of waterproof additive to the grout I prefer, which is one from the Mapei range. Anyone ever heard of such practice?

I would be very grateful of any advice as it's causing me some bother

If the walls have already been treated to cure the damp issue, then it should be a simple process of allowing the walls to dry out and not trapping any moisture still within them. Once dry and you are happy the treatment has worked. Then you can tile directly on to them, no need for any addition boarding out.

There are many ad-mixtures for tiling adhesives and grouts, one of which is a waterproofing agent. If one is to be used, use the one that is recommended with the adhesive you are using.
