tiling shower wall

[diferentshades]

Hi, thought I'd start a new post as I'm not getting any replies on my old post, and I really need some advice.

I'm doing the shower at the moment, it's in the corner with one side being plasterboard and skim, the other bricks with render and skim and I've made a stud wall to make a third side so it's a 3 walled shower. I battened out the brick wall and put mr plasterboard on all 3 walls. I'm mot sure what to go for next! Bal tanking, homelux matting, kerdi membrane or boar, hardiebacker, no more ply! Any advice guys?
I have a raised resin shower tray, if using a board, do I go down to floor level or stop at tray? Any advice please?

Tanking it with a tanking system you paint on. Don't skim it. Just tank it. Then tile it.

 

[Dan]

Oh and tank down to shower tray, and use the tanking membrane to tank actually onto the shower tray by about 10mm.

Then tile down to shower tray.

That then means any water that gets behind the tiles, eventually falls into tray. A really thin near silicone bead around the edge will just be for cosmetics and ease of cleaning then.

Don't forget to tape internal corners as well.

Thanks for your replies.What tanking system do you recommend? Nothing too expensive mind you! I live in ilford Essex, and other than topps tiles, the other sellers seem to stock only aqua panels, hardiebacker or no more ply.

You could try aqua defence...

As Dave says try Mapei Aqua Defence, it's good stuff to use & easy to put on.
I used an Ardex kit last week & wasn't overly impressed with it tbh.

Had a look at the mapei aqua defence, it covers about 15m2 and is about a £100!

i only need about 5m2. They do another kit on screwfix by mapei, but covers upto 4m2 so I fall short by about 1m2

Oh and it comes in a smaller tub now.

Anybody wanna go halves! ;-)

Need something I can pickup tomorrow, anything else?

 

[Qwerty]

Dave & Stef are right..... Aquadefence is a fantastic product.

The kit from screwfix you mention is Mapei Mapegum. This is very similar to aquadefence but requires a few layers and is not as rapid setting. Daves offer is very good.

The mapei kit ...... http://www.NoLinksToThis/p/mapei-shower-waterproofing-kit/78484 ..... will cover the 5metres you require even though they say 4metres. Use a 4" roller and a large roller tray and you will be fine

 

[diferentshades]

I think I'll get the screfix one.

to Dave, you serious about the discount? Can't tell with the smiley face and all!

 

[diferentshades]

This is what I'm working on, I have removed the studs that are against the plaster wall, was going to use a 700 tray, but went for an 800

 

[diferentshades]

On the phg website, with vat and delivery, it comes to £92 odd quid.

Cheers Dave and all.


if I had time, I would give them a call, can't see it arriving till tues/ wed. Thanks though.

I'll give the mape gum a go, it's my one shot at this with baby coming and all.

just to be sure, better than bal wp1 and homelux sheet? If so I'll pop to screwfix first thing in the morning.

thanks again guys.

 

[diferentshades]

Sorry, got a quick question. When I put the plasterboard up do I use ordinary drywall screws and do I need to fill the heads of th screws? Or just prime away.

 

[Dan]

Use the proper plasterboard screws for wet areas. Then tank over them.

 

[diferentshades]

Do you know what they are called?

- - - Updated - - -

Are they the zinc ones?

 

[Dan]

I think they Are yeah. I couldn't think of the word I wanted to say anodised but that's not it.

 

[diferentshades]

Cheers Dan.

one more question
dou know the kind of weight this tanking system can hold regarding tiles?
i have not chosen any yet, just want to know my options. If weight was an issue, could you screw 6 mm hardiebacker over the tanking over the plasterboard and into studs, would this increase holding capacity in your opinion?

off to the shops in a bit and want to go fully armed!

 

[Qwerty]

No, do not fix hardi over it! It depends what tiles are you fixing up. If real stone then better to use marmox or wedi instead of plasterboard

 

[Dan]

Yeah you could do with knowing what tiles you're fixing first I think. Plasterboard is better than skimmed plaster, but your tile backer boards fixed to studs are the way to go with heavy tiles.

 

[diferentshades]

Sorry for all the questions guys.
i'm a carpenter by trade and I'm pretty good, but when it comes to doing things in my house, I'm always indecisive! Knowing the cost of things and knowing that I work hard for a living, I always tend to over engineer things.

by the way, I asked advice on the forum when I did the floor and promised some pics so here goes
