Making good

Personally, for drill holes and short chases that will be on show, I have found the Ronseal really fine filler  here  to be really forgiving, and fast so gaps can be filled and if need be sanded to shape with a flat block, or a bit more dobbed in during one session, as if you do things in the right order, by the time the tools are packed up it is already going hard.  It is also almost un-naturally light, and  does not do that 'dripping porridge' sagging thing like the water based stuff. It is also fine enough to work into cracked plasterboard joints and so on, or to fill bubble holes in previous filling that is a bit rough. I tend to use sand and cement and or  backing plaster for large damage though, but of course that needs overnight to go off.

It does go off in the tub though quite quickly once started, so seal when not in use and certainly not worth getting too much at once. The price I think reflects the convenience of use.

I agree with the above though, nothing will stick to a flaky surface, so prep and clean up before trying to fill is key, and not being afraid to build up in layers if need be, remembering to scratch the layer below to give good keying in.
