building a wetroom finished with Microcement - Tile Advice

[Minmax89]

Hi guys.

So, I've been asked to do a bathroom for a customer but I'm not sure the best way to go about it.

It's an ensuite in an old georgian house, 1st floor. I went to see the job a few weeks ago but could actually get into the room as it was full of building materials (they're renovating the place piecemeal really)

The room is 3.1m x 1.2m. It currently has a bathroom suite in it. What the customer wants is a wetroom (shower one end, wall mounted double basin, back to wall toilet, etc.). However, it is not getting tiled. They want to use a product called Microcement on the walls AND floor to give a polished concrete look to the whole place. The customer has spoke to the supplier in Ireland and they've said its completely waterproof and will be fine for the floor too (as part of an already tanked wetroom, etc.)

So, I'm a builder who normally preps a wetroom for my tiler and I'd usually follow a plan like this:
wetroom former. 24mm at the edge supported on ply between joists, etc.
18mm ply on rest of the floor. 6mm marmox board on that to meet former.
All joints taped, followed by tanking solution.

But I'd do all that ready for tiling. Has anyone used this Microcement or anyone got any practical advice to approaching this job?

This is the stuff:
Microcement Wall and Floor Kit, Beton cire, Micro cement, Micro screed - https://www.imperaitalia.com/product/microcement-floor-wall-kit/

Many thanks!
Adam

To be honest I would contact their technical department and ask them to send a written method statement for the application you are intending to use it for .

Hi Adam,

I recently attended @ISOMAT UK and received an input and some training in the use of microcement. It is not something that can really be explained in typed form on this form, but contact @ISOMAT UK and ask them about their microcement products

Get a plasterer to do it........ just like Venetian plastering technique.

There are loads of Youtube videos on Microcement

Thanks guys.
Just got an email from the client with details about the rep here in Ireland. I’m going to contact him tomorrow with my questions. One of which is how thick the final product is.
The client has asked if I want to apply it but I’m going to give it a miss. However, the prep is all my responsibility so need to get it right.

Plan Tec - how thick is it? Client says 20mm??!!

Isomat's video

5mm thick at most and the plastic mesh sheet.

Microcement can look beautiful! I would suggest trying to find someone who specialises in it or ask the supplier of the materials if They can suggest anyone. The customer obviously wants a lovely room with a very specific look, not something to take chances on

 

[Minmax89]

Yes, I deffo won’t be trying this myself. I watched that video above (and a few others) on YouTube and it looks like quite a skilled task.
The company that supply it here can get someone to apply too so that’s probably the route we’ll go down.

Is it supposed to look like polished concrete? With sparkling flecks kinda thing??

 

[Flintstone]

All different styles of it, black looks great, like a satin finish

 

[Minmax89]

Yes, they’re going for the satin finish. Not sure the colour they’ve picked though.

Nowhere near 20mm. More like 3-5mm at most

3-5mm of cement onto a wedi type wet tray?
Oh-oh!!

Did you notice the grey sofa in Isomats meeting room Geoff?
That’s just a block of polystyrene sculpted in to shape and covered in Microcement. Bit hard to sit on, but it’s certainly crack free.
All their sinks are custom made, and are all constructed from mdf and again coated in Microcement, it’s a pretty amazing product.
