First tiling job after my course with UKPTT

[James De]

Hi guys,

I'm currently on my first job after finishing the 9 day course with UK Pro Tiling Training, which I must add was absolutely brilliant!!!

So after removing the 7m2 area of mosaic tiles the plaster behind the tiles just crumbled off the wall due to previous leaks.

I'm thinking of dot n dabbing some Knauff Aquaboard to the brick walls. Can anyone tell me if there is a better idea?

I'm only boarding the area where I'm tiling (on both walls the bath/shower is against). Thing is, the good plaster which I'm leaving on the walls is an inch thick - hence the dot n dab so the boards meet the good plaster flush.

Many thanks
James

The plaster is lime mortar which has been reskimmed at some point, I'd be using the likes of Marmox type boards and screwed using the special washers.

Chop off at least anything loose and dot and dab a board on, any suitable board, it doesn’t really matter. It’s best practice to waterproof tank any shower areas before tiling.

I would cut out the remaining plaster in that area and reboard as the others have said.

I have added the actual image of the issue into your post for you

Whitebeam, I can’t seem to find a stockist of marmox anywhere and I need them for tomorrow, I’ve tried travis Perkins and jewsons which are listed as stockists on the marmox site and nothing. Do you know where I can pick some up from?
***EDIT***
There’s a place called SIG in Ruislip that sells it I think, I’ll try them. But if you do know of a major chain that sells them that’d be great!

Do you have a Ctd near by?
They sell the wedi/marmox type boards.
Anything like Jackoboard, Dukkaboard.
It’s all the same stuff.
It’s a foam board with a cement type covering back and front.
Cement boards like ‘Hardie’ and ‘no more ply’ still need tanking in wet areas.
The wedi style boards only need tanking on the joints and over mechanical fixings (screw and washers)
Topps sell wedi now, but I’ve no idea on their prices.
Just make sure you get the washers, it’ll stop screws pulling through.
Even B&Q sell this type of board now, not sure if it’s order only tho.

Dot and dab plasterboard and then tank it if it’s in a wet area. The cost of the tanking outweighs the cost of the Tile backer board and is far quicker.

Unless of course you’re hanging very heavy tiles off it.

No just standard metro ceramics.. any recommendations on tanking kits?

 

[Waluigi]

Tilemaster.

Or Mapei as that’s the most widely available kit on the market. I prefer Tilemaster though.

Remember, when dot and dabbing a whole wall, you need to dot a continuous rim across the top of the board.

Cheers Walugi, yeah I’ll prob do more around all sides and then dot n dab the centre pieces.

Ardex taking is another good tanking kit if you have a CTD nearby

Yeah I’ve got one just down the road but just been to the website and searched for it and nothing comes up under ardex or tanking.. looks like on their website they only sell tiles :/

The Ctd website is not the easiest of sites to navigate. Which is your local store?

Tell me about it!! Local store is Hanwell, W7

Local store is Hanwell, W7

Try this link.

I don’t know the Hanwell store personally, so don’t know what they stock. But generally they’re all similar, and all stock the basics like boards and tanking kits.

Just order this. £54 delivered to your door.

Or the Ardex. Both are very good kits. Slightly different concept with the Ardex

Just went to CTD and opened a trade account and got the Ardex kit with some cement/foam boards with the washers. I’ll tank the joins, silicone the bath to the boards and then tile (do the cement/foam boards need to be primed? I can’t remember and my course notes are at home - I’m sure I prime everything regardless, right? SBR of course ).

No need to prime the cement boards

 

[Flintstone]

I would prime the cement boards even if Just to remove any dust

You do indeed mate
Do I need to drill a pilot hole through the cement/foam board before driving a screw through it?
