how deep for adhesive bed

[Zaffy]

Materials= Glass mosaic on mesh / Mapei Adesilex P10 adhesive / Mapei Isolastic latex.

Base = Ply screwed to concrete.

Depth = From base to final level 13mm / Glass mosaic 5mm

13mm - 5mm = 8mm for adhesive.

Question = Is 8mm too thick for adhesive?

Thanks.

To answer your question... Yes, 8 mm is too thick. A 4mm trowel should suffice.

However, your prep concerns me. Don't tile to wood. It WILL fail. Tile backer board instead.

That worries me....

why are you plying onto concrete. self level would be better. i am thinking its for the floor?

6mm backer board over the ply? Not sure why you've used Ply, but I hope you've primed the sides and back, to stop moisture getting in...

 

[steve187]

not really the correct prep, hope you are asking before doing, and a small notch mosaic trowel should give you about 2 or 3mm of bed

I was trying to keep my post brief, but I feel I have raised too many questions doing this, so the full story is.
Site = bathroom floor (the drip area, if you pardon the expression).
Size approx. 2sq meters.
Builder screwed plywood down ready to tile but ran out of time, he said he would be back sometime. It's been a long, long time.
Rang another tiler, he has moved up north. Rang another tiler, job too small, but will do it for £***. Rang a builder friend, he will do it for me one day, been waiting a long, long time. Rang another tiler, he turned up. He went away, it's been a long, long time. In a way, this is good, it means there is plenty of work out there for good workmen. However, over a year on, I am going to, with the knowledge from this forum, do it myself. So I am where I am. I have the ingredients listed above in my original post. From the top of the plywood, I have 13mm depth to play with. The tiles will take up 5mm. I hope this helps you to help me.
From what I can understand so far is, I should take away the ply. I will do that right now. It might take me a while, because it is screwed down very solidly. I hope it isn't glued down too. The ply is about 5mm, when removed, this will give me a depth of 18mm to work with. While I am doing that, can you tell me my next stage thanks.
Thank you all so much for your interest.

Correction,
Sorry the area is about 3 square meters. Fiddly area, around loo and pedestal sink.

 

[dave l and l]

can you get the toilet and pedestal taken out. then self level the floor

 

[Sean SML Tiling]

Why dont you fix 6mm backer board to the ply add the tile which gives you 11mm and use a 4.5mm trowel which will give you a bed of roughly 2mm of adhesive =13mm problem solved

Zaffy where in Bucks are You ?

 

[beanz]

Steer clear of self levelling compound. A first timer, and mosaics would not be a good combination!

 

[Martyn Leeds]

Scrap the ply for sure

What's the reason for the final floor height measurements? existing floor in adjoining room(s) ??
Can the Sink & WC not be removed? cutting mosaics round obstacles might be a tad tricky?
If its a DIY is it possible to swap the mosaics for a normal tile? might be a bit easier
