Repair Kitchen Window Sil (Pics)

Hi;

I am in the process of re-fitting my kitchen and have a problem with the window sil. The kitchen window sil which sits above the sink was tiled, when I removed the tiles from the sil 1/2 the tile was sitting on a ledge made of render and the other half nearest the window was suspended able a gap in the window frame.

As you can see from the pics I have just had the walls re-plastered and the plasterer has skimmed the face of the window sil but left the sil itself for me to sort out.

I want to build up the sil to provide a base for either a PVC window sil or more than likely it will be re-tiled as tiles will be harder wearing.

How should I build up the sil? I was thinking of using mortar and possibly a wire mesh support to bed the mortar into and then tile onto the mortar sil or screw / glue a piece of hard wood onto the sil and tile onto that?

Any help / tips would be appreciated.



The sil sits over the cavity

If it was me, I would buy a pot of ready-made plaster and fill the gap between the window and the original plaster, making it level using a piece of wood. Wait a couple of days and then re-tile, use a sealant between the tile and the window to stop any condensation going under the tiles.

close the cavity then dot and dab a plaster board on the bottom ready for re tiling.

Skav - temp batten across front, fill gap with mortar to appropriate level, when mortar's dry remove batten. Now how to finish the sill? If you use tiles on the sill you'll run the risk that the grout will get dirty (dust, settling kitchen grease, etc) and WILL always look grubby. As you appear to have plastic windows consider using a uPVC window board ... it'll match the window and WILL be wipe clean. Places like Wickes do these plakka boards.
