Hi @elbow,

Thanks for your question about repairing your concrete windowsill.

You should start by removing any of the coverings and cleaning the surface thoroughly with a stiff bristled brush, so the concrete underneath is exposed and clear of any loose material. You should then apply a bonding coat of BondCrete as per the manufacturer's instructions.

Once cleaned and primed, using a trowel apply Dunlop 5kg Ardit Rapidset Repair Mortar and shape the area to match. Smooth the area as best you can to begin with, but keep in mind there is around 15 minutes where the repair mortar will still be workable, so don't panic if it's not perfect to start. 

Once the mortar has hardened, you can go over the area with a damp sponge to smooth and lightly texture the mortar.

Let me know if you require further assistance.
