Hi all.

Looking for a bit of advice re adhesive - firstly I'll probably narrow it down to Mapei because we have an account with a Mapei disti and can get good prices - unless there are any overiding factors.

The project is a bathroom / wetroom.
Suspended floor with ply, wediboard, UFH and Mapei Fiberplan SLC
Shower area is Wedi tray with Wediboard walls.
Rest of room plastered.

I'm looking for recommendation for adhesive for the following situations.

1. The main floor is to be tiled with 600 x 400 granite (need to deal with upto 5mm low areas in the SLC)

2. Shower area (walls and tray) to be tiled with 300 x 300 marble mosaic with 23mm tessera.

3. Floor to ceiling basin splashback - there will be a continuation of tile skirtings to form this splashback. The tiles will be the same as the floor tiles (600 x 400 x 15) flamed granite.

Also with regard to 3. above what would ppl recommend - these are obviously much larger tiles than one should apply to plastered walls - is there another solution other than hacking back to the brick and applying a board or render.

Any advice greatly appreciated
Thanks

are you going to waterproof shower area

It is waterproofed Jay.. Wedi boards..

well there you go didnt know that

wedi Tilebacker

what are the joints done with

A tape that comes from wedi as well..

Wet Areas - Mosaic Tiles

And these are the fixing sealing parts used..

Fixings

one to look for thanks Dave

but whats in the pic above (tubed stuff) or plaster

it will be a waterproof mastic that they sell.. like a tanking gum..

thats a relief thanks cant get wedi down here looks and reads well is it worth sourcing

It is also used for insulation on UFH Jay and can build walls with it etc..

It can also accept heavy weight of stone tiles etc.

back on topic in this link from Dave it states wich adh and grout to use http://www.wedi.co.uk/wetstud.php

Yep - Wediboard also Wedi shower tray, but actually didnt use the Wedi stuff for the joints - I used Mira Safecote and Mira Multicoat, fixings and principle's the same - you can use any suitable tile adhesive over the wedi - but it is partially and will be completely covered with SLC by the time its plastered. Wedi is handy stuff with UFH cos its also an insulation board so will keep the heat where you want it. The shower tray is 40mm thick with gully and preformed falls. Dukkaboard do similar products.. (had to mention that - it was beginning to look like I was a Wedi salesman lol).

Going back to the Adhesive - Another one I can get on account at a reasonable price is: Larsen “Professional Flexible Fast Set” Any thoughts?
