Cast Lime / Limestone Window Cill - Filler

[vards01]

Hi All,

I'm renovating the exterior of my 1890's house and the cills are in a hell of a state, can anyone recommend a decent filler which is easy to tool and sand-able for this purpose, and durable enough not to just flake off within a couple of winters.

I have some Tetrion 2 Pack filler which is great stuff but it just goes off too quickly with the amount of filling and reshaping that is required.

Thanks in advance.

Have a look at the Toupret range

Yes I'd seen them on Screwfix / Toolstation, but was looking for someone who'd been in this situation before and had a product recommendation as there are a couple of types.
