Tiling over timber lintel - Tile Advice

[Tony Prima]

Hi everyone, I've been dipping in and out of hear for a few years, always the best advice available.
My question is how to tile over an internal timber lintel over a window, only about 125mm in depth.
Would SBR do it or do I need some kind of mesh fixing to it?
The plaster around it has been tanked using Mapei Mapegum WPS but wasn't sure if it would bond to the timber.
I did think of using plasterer's pre grit but again not sure of it bonding to timber.
I'm using Metro tiles
Please see attached photo
Many thanks Tony
