Bathroom Skimming Prep With Pva Before Tiling (wet Areas)

[Crumbs]

Hi, i am looking to re tile my bathroom and have got rid of all the tiles. Unfortunately some plaster damage has occured, i want to skim the damaged areas and use PVA between skim coats.

I know using PVA is a big mistake before the tiling in a wet area, but is it okay to use PVA before a skim coat when its in a wet area (shower above a bath)?? Does the same apply or is it safe?

Much appreciated

Hey bud, i have decided against using bath seals. The sealux ones do look good but i dont feel confident installing them correctly and worried they will fail down the line as i have read online sometimes this occurs (most likely in poor installations) so will go with what i know (silcone). Once the addy / tiles are fitted the gap wont be as much i guess. Will silcone the tub to the wall before hand > tank > tile > silcone then seal the grout. Hopefully this will suffice

The tanking tape, when laying it down - do you centralise it so half is on the tub / half on the wall or more one side? Hopefully the tape is wide enough for the gap Thanks for your help much appreciated
