Preparing walls

[liverplum]

Morning.

I've got a shower cubicle to put up in the corner of a room and the customer has asked if I can replace the tiling for him as well.

My query is regarding proper preparation of the two walls. One is the brick outer wall of the building which is plastered on to and the other a stud wall that is plasterboard.

Can I just use a primer like Primer G on both walls and then tile directly on to that?

Cheers

Do you know what tiles you will be using and will you be tanking the area ?

[liverplum]

The tiles are going to be either ceramic or maybe porcelain.

Would I need to tank the area as well as use a primer?

[doug boardley]

your plastered walls will be unsuitable for porcelain if they've been skimmed, (too much weight pulling on the skim), plasterboard will be fine. Primer G will be fine if you're using mapei powdered adhesive. Tanking should be applied to the areas that are gonna get wet

[liverplum]

Best avoid the porcelain then
So you would use the primer g first and then the do the tanking?

[Sir Ramic]

Yes , Prime, tank , Tile No primer needed on top of tanking.

Excellent thanks a lot fellas - This forum is a god send. I've helped lay tiles on jobs before but am only really offering to do it for customers on occasion by myself now as being able to provide the whole service is obviously a good selling point and I started out on my own last year (as a plumber). But there are such a variety of possibilities with every job and as someone who has never worked for a proffesional tiler and learnt that way it is a real minefield!

Not sure I can tack this on to this post as well but the chap has a tongue and groove oak floor int he bathroom and he was asking about tiling straight on to it if it's level enough....any thoughts?

floor like this one

[liverplum]

it is very well stuck down with very little movement anywhere. I thought I could stick some more screws in it anywhere it did move a little ??

[Sir Ramic]

No, you will need to overlay. If the floor is free of deflection you coulduse 6mm Hardbacker or NoMorePly..if the floor has deflection 18mm WBP ply.

[Polishtradesman]

You need to screw board to it or better two boards, make cross like skateboard and then polymer dispersion-based primer and then adhesive C2 S1 or S2 depends on movement.

[liverplum]

Ok thats good to know as I got the impression he may want me to put some tiles on the floor for him at the same time and I wasn't sure.

be a bit carefull here liver
are the floors oak, i ask cos youve shown t&g pine and if the floor looks like that but in oak its likely to be an engineered oak floor
some pine floors are stained an oak colour and resemble oak
oak floorboards are rare due to the cost but you do find them occasionaly in older buildings

an engineered oak floor is laid over an existing floor similar to laminate flooring

is the sub floor wood or concrete
is the floor a traditional floorboard stained to look like oak
is it laminate flooring or engineered oak flooring

if it is engineered on to a wood floor it should if installed correctly already be overboarded between the original floor and the oak boards and wont need overboarding

without seeing the job its impossible to say

[liverplum]

I would like to say you have cleared that up for me Mike

I didn't mean Oak I meant pine.

However I think what you are hinting at is the complicated nature of the question regardless.
