Spent the day stripping the old tiles off the bathroom walls

Now there are patches where the old tile adhesive has striped the original plaster skim off the wall down the the paper backing of the plaster board, and in some areas its gone past the paper to the plasterboard itself. There is also a few smaller indentions where the chisel went more into the wall than taking the tile off.

I am going to re-tiling the walls with porcelain tiles but would like to have a little advice......

Do i need get the walls re skimmed with plaster or could i get away with a waterproof BAL (?) coating on to the walls :?:

The bathroom will not have a shower in, just 100% tiled wall & floor, but will have a bath which does its best to contain the water from a 3year olds attempts to splash it all out

Since the tiles are costing quite a lot of money i want to get it right

Are the walls stud work

they are plasterboard, but they don't have any stud work like modern buildings as its the original 1950/60's wall

They are made up by two large pieces of plaster board with the void filled with what looks to be cardboard honeycombe

this means i can't just replace the one side of the plasterboard

Paramount board is what it's called, don't get the wall,s reskimmed. Where you may have made holes prime first and fill will some of the adhesive you will be using, prime the whole wall with the same primer (not pva) bal apd or similar and use a powdered adhesive for your tiles, a single part flexible

You could also use a ONE STRIKE filler to make up the holes and indentations. Easy to use and goes off quick and sets well. Then prime with apd primer and use a flexible powdered adhesive to fix tiles to the walls.

Thanks very much for your response, can you recommend a powered adhesive (I think my tile supplier [YTC, Leeds] sells BAL)

I will be using 7mm 300x300 tiles which are polished porcelain, on both the walls and floor (the floor will be replaced with 18mm(?) ply) as the original chipboard has gotten too wet

Bal flexi is a more than adequate adhesive and a good choice. My personal choice is Mapei but you should have no problems with Bal.

Just make sure that the adhesive is flexible, and suitable for fixing porcelain. Don't use ready mixed stuff!!!

I'd probably use a 2 part addy for the floor, or Ardex 7001 as more flexible. Not essential, but you want the best result / performance.

imo strip the walls back to the stud work, re plasterboard with 12.5mm board, tank and tile

I would if there was stud work to do it

Paramount board doesn't have any

Don't forget the sealer

but the travaline boarder would

The tile i am using is going to be ARKIM IMOLA 30x30 Micron ML

Please do normal porcelain does not need sealed, if it is then subjected to polishing it's surface is opened up therefore needs sealing or you will have expensive stained tiles

Do i just use a roller (foam type or normal??) to apply the sealant after a few hours of fixing, prior to grouting, then again once the grouting done to seal the grout from staining

i think i used lithofin on my travertine tiles, in the 2nd bathroom, it there any recommendations for polished porcelain?

How often will i need to reapply, mainly the floor, but the walls too (taking into account no shower)

Seal all your tiles prior to fixing (Fila polished porcelain impregnator sealer) then seal again after grouting.

Thanks for your help on this one, really good to know there are people out there to help us novices

Just a few more questions to go (i hope)

I have spoken to my tile supplier and they have said that the tile i have chosen are very dence, and will have micro pours that could stain over time, so i am going to test the sample tile i have with some red wine and kids green shampoo etc. But will most likely add it to the order.

Added the BAL ADP Primer

The floor adhesive is what was recommended Ardex 7001, but the walls was BAL RAPID (not Flexi) as suggested, so i have changed this to flexi
Where can i get "5L One strike filler" over the counter in Leeds?

Just been reading Fila MP90 tech sheet, what does the following quote mean and what machine is it refering too ????

2.</B>After 24 hours, when the floor is dry, remove the excess using a single-disc, professional cleaner (white or beige disc) or a household polisher fitted with felt pads

just done a stain test on my porcelain tile sample

as its had tomato sauce, red wine, vinegar and some shower gel on it for the last hour and gave it a good colouring in with a dry wipe marker pen

My finding are

No discolouration, but holding it up to the light i can see a out line where the wine, vinegar and shower gel was.

it sort of a patch of less shinny polished area, so i guess sealing the tiles will keep this from happening??

more worried about the showergel as i am unlikely to have tom sause in the bath with me
