Tiling an overhanging ceiling

[wayne]

Got a shop wall and overhang to tile Tuesday which is shaped like an upside down L. Tiles are hexagon 8mm ceramics 150x150. What's the best adhesive to fix tiles with? I suppose it's just like tiling the top of a window reveal but on a larger scale. It's all been clad in plasterboard ready to go which i think should be fine for that size tile.

As it's an external overhang I would'nt even consider plasterboard...

You'll get better grab on a backerboard too?

It's internal in a coffee shop. Can probably overboard it with backerboards when I get there. Thought plasterboard would be ok as tiles not heavy.

I've found Ardex X77 to have great grab.

Would be inclined to cement board over it and use 2 part.

 

[AliGage]

Out of interest, why a 2 part?

Plaster board good but don't prime it

8mm 150x150............... Surely White Star could handle this? i always find the grab on tubbed gear is much better than powder.

Slightly off topic, why not prime it ?
