1st Job: Hello

[boxfreak187]

Hello. I wish to tile the walls and floor in my bathroom. i am looking to use mapei super flexible adhesive, mapei flexible grout and mapei plaster primer on the walls. The walls were back to brick, plastered with browning and skimmed with multifinish. One wall is plasterboarded. The floorboards are 13 or 15mm thick fixed firmly and i am going to use WBP 12mm plywood on top. From what i have read on here 12mm ply is no good but im going to use it anyway. i am possibly going to use 18 x 18 tiles, but have not decided yet.

Now my questions start!

since the floorboards are fixed firmly i am going to screw the ply down at 150mm apart. but before this the plywood needs to be primed. i have some cementone sbr, is this stuff ok to prime the back and sides of the plywood with? And if i need to, will it be ok to prime the face of the ply with the same stuff? Or what about the mapei flexible additive, is this ok for the ply also? If it is ok to use both ill stick with the sbr since i have a tub of it already.

Now to the platerboarded bit. Is it ok to get some tubbed adhesive to stick the tiles on that bit or should i stick to using the same adhesive all around the bathroom. If i do this, do i need to prime the board?

The skimmed wall plan was to prime it with the plaster primer and tile straight onto it using the flexible adhesive. Is that ok to do, or should i use another adhesive to stick the tiles onto the walls? Like the mapei ultimate grab.

I would prefer to use the same adhesive all around but if i need some other stuff i suppose i will have to get it anyway.

Since the walls will be completed in a day or 2, will i have to wait until the skim is dried out totally before i lay down the ply. if so how long should i wait for the skim to dry out totally? (skimmed onto browning).

Im sure i had some more questions, so when i remember them ill ask around again.

Ta very much

We really need to know what tiles you will be using on the wall , Size and material ( Porcelain or ceramic etc)

[boxfreak187]

hello Sir. Nice name lol! yes the tiles i will most probably get are 40cm x 25cm ceramic.

[whitebeam]

I would use a powdered adhesive for that size tile

[boxfreak187]

yes i am going to use mapai flexible adhesive all around if thats ok

[whitebeam]

Thats fine, would'nt use any tubbed gear

[Sir Ramic]

That would be fine.

Waht made you chose Mapai? Good stuff just wondering?

[boxfreak187]

ok so mapai good to go. am i ok to primer the ply with sbr then? even on the face if needed? Mapai is good stuff, thats why im using it

[Prem Tiler]

What I mean is how did you know it was good stuff? Was your dision the result of an advert, word of mouth, a promotion?

Check manufacturers instructions, some say yes others don't need but if you need to prime sbr will be good at 3-1

[boxfreak187]

word of mouth mate.

can i just tile straight over the plasterboard without doing any prep to it then?

[boxfreak187]

by prep i mean use sbr to prime the plasterboard prior to tiling using mapai flexible adhesive

[whitebeam]

Yes mate

Helloooo and welcome..

by prep i mean use sbr to prime the plasterboard prior to tiling using mapai flexible adhesive

you'll need to prime any exposed edges that aren't bound by the paper, ie where you've cut the boards to fit.
