What is the finished adhesive thickness?

[bcraig24]

I'm tiling my shower with a 150mm tall step/threshold that I want to place a row of 100 x 150 tile on top of making the threshold approximately 100mm thick. I'm in the process of knocking up the timber framing for the shower and had a thought about how thick my frame should be and I am unsure about the thickness of adhesive I should take into account.

My actual question.. Does a 6mm square notch trowel leave a 3mm thickness of adhesive once the tile is pressed down into place?


The threshold will have 4mm tiles front, top and back. Laid on 6mm tile underlay with 4mm square aluminium trim alone the corners ( I havent bought this yet but I assume the square is 4mm and the lip that sits under the tile is at least an additional 1mm). On the shower side of the threshold the tile underlay will have a 6mm batten underneath. My 2x4" timber framing comes up at 92mm wide.


4 + 1 + 6 + 92 + 6 + 6 + 1 + 4 = 120mm the finished thickness of my threshold.

Say I had 2mm grout either side of my top tile to the edging that would leave a 106mm gap. Too large for my 100mm tile. I was thinking I will just rip 6mm off my 92mm timber. But I haven't taken into consideration the thickness of the adhesive.

From what l can gather,the finished width of upstanding is 114 mm. so the width of framing and everything else built to reflect that size. Tile the top first, l would allow a bit of play on the sides as regarde adhesive thickness, also are you intending to waterproof? May need to take this into account also.

A 10mm notch trowel gives a 3mm solid bed.

Sorry I accidentally ended up in a private conversation with 3_fall.

I'll continue in here.

I've got 150 x 75mm wall tiles to line my shower laid in a subway pattern. For my step I will continue the same tile and pattern front, back and top of the step. But because I want my step closer to 100mm thick rather than 75mm (one tile) or 150mm(two tilegs) I also bought a handful of 200 x 100mm wall tiles of the same make that I will just cut the length down to 150mm to lay on the stop of the step. So I need to calculate what thickness I need to cut my 92mm wide framing timber down to so I can fit this 150x100 tile without cutting it further and allowing for 6mm tile underlay, adhesive, waterproofing, tile edging.

The top of the step is just one row of 150x100 wall tiles.. should I actually look at getting a floor tile for this?
I assumed that the little load this step will take my wall tiles would be fine.

My wall tiles are ceramic.

I've been told to use a 6mm square trowel for my walls and I was going to use the same for the step also. Should I use a 10mm for the top of the step either way if I end up using the wall tiles or thicker floor tiles?

Personally, (fianances allowing, of course) l would build your threshold as shown, waterproof and tile sides. Purchase a one piece threshold top, with polished/finished sides with impervious stone or porcelain. - Stronger, cleaner, simpler,with no need for trim.

That sounds interesting. Can you post a link to an example of what you're suggesting?
