Travertine tiles on plastered wall - weight issues.

Possibly (as usual) :)

My take on this is "if there's doubt and an extra 10% will bomb proof it, then bomb proof it"

I am really curious to know why I've never come across this 20kg/m2 figure before...

I'm also curious why my diluted SBR sat on the surface on one section.

I did wire brush my bathroom when I did this to break the glaze and that soaked up SBR. Not sure why I forgot to do that here...

It does seem suspiciously light.

Might the plaster already have had some waterproofing additive in it?

Still you can get the same problem trying to prime very highly polished plaster.

Having a layer of insulation behind the tile may also reduce the amount of condensation that forms on it when in a steamy environment. That could be worthwhile.

I think that was it - this bit is super polished. I guess it might be the plaster too. My old man used sirraphite (sp?) and could get it to shine like glass.

Regular skim seems to go on dull but smooth.

Yes - my thoughts too. I'm looking at the 12mm marmox for the outside wall and the 6mm for inside (Marmox says they are all rated the same).

I'd like to hang it principally on stainless 70mm ish screws but also have some adhesive to make it firm and solid. Marmox seem to suggest NoMoreNails type products, but solvent free versions. This would take no weigh - just to remove possibilities of slight flexing and hollow noises afterwards.

I see a day or two to do this at most. Won't bother with the window reveals as they are small and can't afford to lose the width.

Sirapite? If it's the stuff I'm thinking of I loved it for small patches (all I can manage) as it was so smooth. And hated it as it was so hard to drill or chase.

Wow. No, I don't think I have ever come across a shear stress in the building trade before either.

I could see it pulling off the final plaster of paris skim on a Victorian lath and plaster wall (as could you, I am sure). Only other time I have seen this sort of thing is associated with fairly obvious damp.

Fair point, if it's the same property.

I agree, that changes things.

Agreed. Not familiar with that product, but obviously it's designed to take tile adhesive.

An unplanned benefit of putting 50mm of Celotex between the tiles and a south facing wall - makes a huge difference in use.

I have good news and bad news, again(!)

They're from these people;

They're 13" x 13" (although IIRC the shop had them in other shapes). They don't seem to have a reference number on them, or on the box. The receipt from the shop doesn't help, either.

The bad news is I can't find them on the web site. A search for "travertine" doesn't help; none of the results are the right thing.

There's a photo of the bathroom floor here, if that helps;

We noted that, too. The travertine mosaic tiles we used as trim were little more than £1 each (for a foot square mesh backed "tile").

Their beige tile looks interesting but too big for the wet room

They look very similar to the last ones used here.

I found something similar at

Unicom Starker product natural slate Autumn in a 30.5x30.5

Sadly bookmarking the page doesn't take you back to the right place.

Those don't look very much as I expect travertine to look i.e. full of holes and fissures that need filling ...

That's because "travertine" ceramic tiles don't look like that.

You can get prefilled trav - that's what I have.
