Tiling over emulsion on Shower wall.

[chrisjkerr]

Hi all.

My second post here. Thanks for all the help in the past regarding the floor tile preperation.

I have a few more questions if you don't mind helping me out?

The old bath (no shower) used to have tiles around bath area but only 3 tiles high (20 x 25). Above the tiles was just emulsion, as was every other wall infact.

I'm looking to put an electric mixer shower over the bath and tile the whole room with 40x25mm tiles. Where the tiles used to be, it's just plaster from the skimming and above is emulsion. My questions are.

1, Will i need to sand the emulsion right back to plaster over shower and bath area ready to use a tanking kit?

2, Will i need to sand the rest of the walls back to plaster before applying the tiles or will scoring the walls be sufficient?

3, I notice that BAL do a tanking kit "WP1" do Ardex do an alternative product?

4, As the Bath that was in was about 1690mm the new 1700 bath doesn't fit as such. Can i cut out a small horizontal area of plasterboard for the Bath to sit in and as such how would i go about sealing that part ready for tiling?


and finally as fifth question, when i chased out the plasterboard for the hot and cold copper pipes, the false wall was basically 3 pieces of 12mm plasterboard glued together. What would you suggest i use to fill the chasing in with ready to tile over?

Thanks again for your help...

Chris.

hi chris

in answer to your emulsion questions, get a couple of strips of duct tape and stick em to various parts of the walls where you intend on tiling. leave them at least 15 minutes and then rip em off! if lots of paint is stuck to the duct tape when you've pulled it off, then you have to sand back the paint.

i did this in my bathroom when i did the same thing you are (no shower previously, put shower in, needed tiling full height). i didn't manage to get much paint off the walls, but i made sure i gave all the walls a good sanding before priming.

if you don't want the dust you could always try a steam wallpaper stripper. alternatively, replace all the boards around the walls with brand new plasterboard. would save you lots of back breaking hard work going down the sanding route.

Thanks GRR.

I actually started sanding some paint near where the radiator is and is was bloody hard work. I think i sanded most of my skin off and created tons of dust. It looked like i'd hardly scratched the surface with the P40 stuff but made it nice and smooth!

When i'm home later i'll try the duck tape option just to see.

Thanks again!

Emulsion isn't suitable for tiling onto as it becomes "live" again when it is wet. It will have to come off I am afraid. Sadly it will take time and is very messy. Use a dust mask, goggles and an cap to keep it out of your hair......happy sanding....:smilewinkgrin::smilewinkgrin: :smilewinkgrin:

chris,

how many people are you disrrupting by having the bathroom out of action for periods of time?

the only reason I say this is, I remember what it was like sanding my bathroom walls. even if you managed to stay covered up from the dust, you ended up with your hands shaking in tune with the sander :lol:

I was thinking that maybe if you marked the walls off into 1m2 sections and then just sand 1 section per night or something, you wouldn't be disrrupting too much and would have less to clean up each time. but it does string out how long it takes you tho :bomb2:

just a thought...

Thanks for the replies.

Great....

Sander time. Maybe i should invest in a belt sander. We have an ensuite and there is only the two of us, so the bathroom being out of action isn't an issue as such. I'll use a polythene sheet at the door so as much dust as possible can stay in the bathroom and go out the window. I doubt i'll be able to sand manually as the bathroom is a 1700 x 1900 so the amount of area would mean me sanding to the bone. I have dust masks and goggles and i aint too worried about my hair....lol...

I think ill look at sanders tonight. See what options i have..

Thanks again!

maybe worth renting a big beast of a sander from a tool hire shop chris

If you do use a steamer to get the old paint off don't leave to long in one spot or you could blow your finish plaster off
