Tiling a garden wall (duplicate threads merged)

[dave1975]

I have a low garden wall which I want to add mosaic tiles to but the bricks are quite bumpy so It will need smoothing out first. Should I render it or use plaster bonding?
Thanks

Can you not baton it out and use cement board to fix the tiles to.

The wall is only about 16” so it seems a lot of hassle. Also because the bricks are so bumpy it’d be a pain getting a fixing

OP,
what you propose works in hot countries but less successful over here.
the soaking, freezing and expanding can blow off low level tiles.

this is a double post mate. i replied to the post in building.

dont ever use bonding on the exterior.

Rendered garden walls don't last long in our weather conditions hence why I mentioned cement board and something like CT1 to stick your tiles on.

Wife tiled a garden table ( mosaic) frost got under surface and after a couple of years most of the tile surface had blown .
