What backing material for bay window render

[padstar]

I am planning to remove the tiled finish to the bay window and replace with pebledash to match the rest of the house. What backing material should i fix for the renderer to apply the finish to?

Tile backer board? Cement Partical board?

 

[dontbelieveawordofit]

preferably a cement carrier.
knauf aquapanel or marmox multiboard or similar.
can also be done with osb and stainless mesh

Would this be suitable -> Product

nop. not recommended for externals.

The Auquapanel i have found -> Link seems to indicate that it is for internal use. Is this what you are recomending?

This product -> Link seems to be for external use.

Are either correct?

 

[dontbelieveawordofit]

the only problem is it states weatherproof not waterproof .and theres no mention of frostproof.
search marmox cement multiboard.

OP,
Why are you proposing to change something thats in good shape, ie the tile hanging, for render that will, esp on a bay panel, come with its own possible problems - eg bays in general are prone to movement which tile hanging will absorb.
Bay panel studwork can shrink & expand and crack render.
Replacement Pvc frames are often badly fitted, and can cause various movement difficulties.

Really dislike the tiled panel and much prefer the rendered look to this area. Plus tiles are not in great condition so would need replacing as a minimum.
