Help needed with Bathroom Tiling

[chris316]

Hi

This is my first post on here, so please be gentle, and bear with me.

I am for tiling my bathroom, walls and floor. And I have a few questions which I would be very greatful if someone could answer, or give me some advice.
My bathroom has plastered walls which had been painted with emulsion paint. Originally I was going to just key the walls and tile over. But when I keyed the walls the paint came away in places so I decided to remove the paint from all the walls, right back to the plaster.
My questions are:

1. After removing the paint from the walls you can still see where the
walls have been keyed/scored right back to the blockwork/undercoat
plaster. Can I tile the bare plaster walls with the key marks, or will the
key marks have to be filled up prior to tiling?

2. Do the plaster walls still need to be keyed/scored now that the paint has been removed?

3. When removing the emulsion paint and keying the walls there are small
areas of the wall where the finish plaster was very thin and has come
away. What would be the best filler to use to patch the
walls up, or would I need to re-skim the walls?

4. Do I need to prime the plaster walls prior to tiling. If so what would be
the best primer to use?

5. I have also had to re-plaster a bit of the wall where I installed a new
shower. Can I tile on top of this new strip of plaster straight away?
or do I need to leave it to dry properly, and if so how long do I need
to leave it?

6. Finally, I also plan on fitting a new plywood floor, does this need to be
primed and if so, again what would be the best primer to use?

Sorry if my questions are a bit long winded.

Thanks
Chris

A paint on type tanking system might be easier than a membrane for a beginner, they cost about 50 quid chris

Hi chris, as faith, paint on is easier. Mapei Gum is good I use membrane, mostly, but it can be tricky if you are not used to it. Corners, tape etc. I would go with Mapei Gum and their tape/ primer. It seems to do the job, good luck mate

Is it an occasional use shower?

Is it an occasional use shower?

Yes.

So, If I prime all the walls with an acrylic primer and tank the walls above the bath. Can I use the same cement based adhesive on the primed plaster walls and the tanked walls or would I need 2 different types of adhesive?

 

[mikethetile]

yes you use the cement based right through

 

[chris316]

yes you use the cement based right through

So, just to make sure I have got it right:
1. First. I need to change the ready mixed showerproof adhesive the tileshop sold me to a cement based adhesive.
2. Prime all the walls and floor with an acrylic primer (Do I prime both sides of the ply floor or just the underside of the ply which is not being tiled?)
3. Tank walls above the bath with a tanking paint after priming all the walls. I have seen this one on screwfix, would this be ok? (Dunlop Shower Waterproofing Kit - NoLinksToThis, Where the Trade Buys)
4. Tile walls and floor
5. Grout tiles

Is the Larsen's flexi tile adhesive for the floor which I was sold (details of the adhesive, I posted earlier in thread) ok?

Everything looks okay Chris. usually just the underside of the ply but read or phone the addy maufacturers helpline

you must be joking do you know what happens to pva after it has set and then comes in contact with water:mad2:

 

[imperato]

well i guess you would hope the tiling has been done correct and no water is getting to the walls

 

[Deleted member 9966]

well i guess you would hope the tiling has been done correct and no water is getting to the walls

what adhesives do you use imperato?

 

[jay]

you could hear a pin drop

 

[Gazzer]

well i guess you would hope the tiling has been done correct and no water is getting to the walls

And how would you go about that Alex ?, seeing as tiles and grout are not 100% waterproof. Theres more than enough info here and all over the internet to prove that PVA has not place in tiling today.
