Tiling onto tanking solution?!

[johnsonjack81]

Hi,
I recently plaster boarded my bathroom in standard board, I know I should have used aquapanel but didn't so have coated the board in tanking solution. Now I am about to tile the walls but was wondering:
should I do anything else to make sure my tiles will fix well to the walls?
The tanking solution is dry, but it looks very smooth and I am worried the tiles won't adhere well.
I intend to begin tiling tomorrow so any prompt support would be very welcome.
Cheers in advance.

What tile adhesive are you using?

 

[johnsonjack81]

Unibond triple protection. Wall tile adhesive & grout ready mix.

Been advised to get some separate cement based grout in addition to make sure there aren't any air bubbles.

I think you may have problems with ready mix drying out on tanking. I'd use cement based - which would be better anyway.

Do "cement based" adhesives exist WITH mould protection?

I'd suggest you use something like Weber Set Plus http://www.tiletown.co.uk/default.aspx?pageID=975 for adhesive and Weber Joint Pro http://www.tiletown.co.uk/default.aspx?pageID=976 for grout. The grout is mould resistant and will be 100 times better than the ready mixed stuff.
