Limestone

[CCTiling]

Got a job coming up soon with Limestone (I think) thats what I've been told to be fitted inside (15mm thick slabs) and outside (30mm thick slabs).

The customer has asked me if the tile for outside can be honed?

The stone has been honed and filled but I presume it must have a bit of a polished look to it.

I was thinking I would need to seal the stone before I started to fix the tiles outside so not sure how this would work?

Also never honed stone before so any advice?

Also was going to lay a de-coupling membrane down as it's new concrete, is it ok to use membrane outside?

Apologise for so many questions in one thread! :smilewinkgrin:

Cheers Ross

Not sure that I'd want honed outside CC, could be very slippy when wet, but decoupler can be used outside tho'.

Yeah I know doug but they want the inside to look the same as the outside

Ok... Honed is a matt smooth finish and deffo not anywhere near a shiny polished finish..

So ok for outside or wet area's.. This is Honed i refer t =o and not the limestone..

Which limestone is it..?

I don't know exactly what the stone is but will find out more info. Cheers Dave

Use a 120 grit honing powder with a brush.
You should be fine. But make sure you put in writing that slip resistance is not slip proof. These products put micro-etches in the surface and it is easy for them to fill with debris over time and loose the slip resistance property.

I would not seal it if they are worried about slip resistance. It's a trade-off they will have to live with.
