Shower Floor Revamp

[DHTiling]

The tuffdec2 trays need sanding to key them ready for sticking the tanking membrane down with flexible adhesive...as these trays are screwed down and need to be tanked.

If you have grout cracking then ye.. it sonds like some deflection and maybe the tray is not supported properly.. these trays can span 450 centred on joists etc no problem if the joists are all flat and level.. but now and again they will flex if not screwed down properly

PHG Wetrooms sell the Tuffdec2 trays along with the Marmox showerstone, both trays sit directly on the joists but they also sell the Marmox shower tray that needs boarding between the joists or can inset into a screed.

I found the tuff2 is a strong material but still needs support.

Cheers,

I think I'm gonna give it a go. Will remove the porcelain tiles ontop of the tray, repair the membrane (if required) then lay the mosaic ontop.

Obviously if i find the tray is busted or not lying correctly I will look at resetting / replacing it.

let us know how it goes and maybe some pics would be good

 

[gb3]

Will do.

Oh, just a quick one. What Adhesive would you recommend? I cant find anything on the tuff website which recommends one? Keraflex do the job? (and with or without latex?)

Cheers.

I used a single part flex to put the tanking on the tray after roughing up the surface.

Hi guys,

Got a few days off work so thought id make a start on my little project.

I have a couple of queries though...

- The tile came off far too easily. Once id removed most of the grout the tile littlerally could be lifted away from the tray with all the adheasive stuck to th tile. Im guessing the grout was the only thing holding the tiles down/together?

- once lifted away, i noticed the tray was damp. (i wouldnt say wet, just mosit) Again im guessing that moisture seeped into the cracks in the grout?

- There doesnt appear to be a membrane of any kind, not even tape around the corners / edges!!!

- The tray flexes only very slightly - not really noticeable - its appears very rigid.

- The tiler appeares to have used ALOT of adheasive, so the surface of the floor tiles are 14mm from the tray. The tiles are 8mm thick.

----------------------------------------

Right, those are all the problems / points ive noticed so far. The tray itself seems in good nick so I dont think it needs replacing.

My question now is how best to proceed? My plan is to:

1. Waterproof it as best I can using Mapei tape around the edges and the coating the whole thing in mapegum.

2. Tile a mosaic directly over that with keraquick and then grout using ultracolor plus.


Does that sound about right? Any other advice / tips please dont hesitate.


Cheers.

That tray should be tanked.. Dural WP is what i use on them.. Is there any fixings in it to the joists.?

 

[White Room]

Rough the surface to the tray so the addy fixs to it.

Rough the surface to the tray so the addy fixs to it.

Ye, i always sand then...before affixing wp.

 

[jay]

gonna make it hard to return wp up the walls now

 

[gb3]

Yeah it's fixed into the joists with screws by the looks of it.Thanks for the replies guys!

 

[DHTiling]

No probs,if you leave it as it is and tile it.. it will leak into the room below.

Hi,

Just thought I'd show you the nearly finished article. Im pretty pleased with it as a first attempt, it drains the water ok pretty well and seems water tight. Its finally tanked aswell! Cant believe it wasnt done before.

Strangely the most difficult thing I found was sealing the corners with the silicone, ive still got to get the knack of that!

Just one final question - Id like to seal the grout. The research ive conducted seems to suggest HG or Lithofin sealers are best for ultracolor plus...but it doesnt seem to be suitable for glass mosaics (mine are anti-slip).

Any suggestions?

Cheers

Try this Tradetiler Seal Guard

How did you seal the tray joint to floor tile and the joint to the walls..?

 

[gb3]

Dave,I took off the bottom row of wall tiles and the floor tiles around the tray and used mapei tape and gum from screwfix, tuff recommend them for use with their trays.Thanks whitebeam, I'll take a look at that.

 

[DHTiling]

Sound.. just some members might have wanted to know how you tackled it.

I know this is an old thread but thought i'd mention this:

If your original "tiler" didn't tank the shower tray, did he tank the walls? Keep an eye on those if i were you.

Just bumping some of the older popular (sometimes not so popular) threads. Probably wont be current discussion these days but I just need to do it. So just ignore the thread if it's not current for you.
