    Crack in concrete window sill...

    Crack in concrete window sill... 8th Jul 09 at 8:22 AM
    I have noticed a crack in our concrete window sill, I reckon (not being too DIY savvy) that its caused in part by being a cheap product and water ingress which during the winter freezes etc and opens the crack further. At the minute the crack at its widest is only 2 or 3 mm wide.

    Can I fill it with a silicon based product (or one you can recommend) and then paint over it, hopefully the plugging of the gap will stop water getting in this winter and we can get another few years out of it.

    Its not a high level window sill, its not likely to injure anyone if/when it breaks and it is towards the outside edge so its not going to cause any structural problems.
    I'm now a retired teacher... hooray ...

    Those who can do, those who can't, come to me for lessons
