Hi Just a bit of advice please...Ive converted a bathroom back to a box room intending to use as an office. The bath when removed had leaked for at least 7 years I reckon (when we moved in) but didn't realise as access was impossible as the bath was tiled all around. My question is; the cement has been removed off the wall back to brick where the bath was due to water & damp damage. I intend plaster boarding the wall all over (H=8ft W=6ft) the wall and was hoping to use 6mm aqua panel up to the good cement which i removed (or fell off) This is up the wall about 3ft up on a 6ft wide wall. I am tanking the wall as well. Should I tank after fitting the aqua panel & plasterboard and what is the best method to fix the aqua panel, Screws or Dob & Dab? Cheers, A Novice.
