Our house is part of a council estate (but has been in private hands for
many years) and the window sills are concrete. Some have a pronounced join
where they meet in the middle, and others are pitted/chipped (under the
paint work). What can I do to improve the appearance? I can use filler on
the top where it is pitted, but that's not much use for edges. Suggestions?
Anything you use is likely to be a different colour and may look worse if
the cills are bare concrete
You could mix some fine sharp sand (silver sand or kiln dried but NOT
builders sand) with cement and add PVA, and then use this to patch the
cill. Alternatively you can get epoxy repair kits for this type of work.
You can't use [decorating] filler externally on concrete and expect it to
last 5 minutes
You will never get an offset joint to look smooth, unless you take a grinder
to the whole surface and feather it in from each end of the cill.
Sorry, i meant to say that the sills had been painted over (several times, I
would guess). They are white, so colour isn't a problem.
Certainly there is a pronounced step on one window, so I wasn't
realistically expecting to get rid of that. I'm more concerned about the
pitting and chipped edges. Pitting is obviously easier to treat. Thanks to
your ideas and the Natural Philosopher. Something I hadn't considered.
