Tiled Window Sills

[mlv]

I have to build some external tiled window sills on an extension to match with an existing building.

The sills are two layers of cut-down plain concrete roof tiles (Redland) cemented with staggered joints to the outer leaf at a downward angle directly below the window aperture.

This doesn't look too easy to achieve without some sort of wooden frame/jig that will hold the tiles in the correct position and at the right angle whilst the cement cures.

Has anyone built a tiled sill? Any tips on how best to do it?

TIA

The easy way is exactly as you have said using timber depending on the width of the cill I put 2 or 3 pieces of say 25mm thick timber batten upright below the cill and fix these to the brick wall with pins or screws then nail another piece of 25mm thick timber horizontally across at the top to support the outer edge of the tile. (it doesnt reallt need supporting but what you have now is a guide edge approx 50mm out from the wall. The bed your lower tile on normal mortar usinfg the front edge of the tile onto the batten. Bed your top tile at mor of a slope than the bottom one and there it is Allow to set for a day or two and remove the battens, Using the uprights means you can point/tidy the joint under the tile

No, but if its like the ones we had, its pretty easy. Tht is a tile was laid over teh clill interior first, then provbaly weighted down, the next day teh top layer could be moratterd on. In our case there was a slid oag frame on tpp off or butted up to the top tile layer.

The stiff mortar will hold the angle you want of itself.
