    Hi,

    Just wondering what to do with these lads. They seem a bit too skinny to get a bit of filler in, just paint over or score them out and fill?

    I don't if you can get exterior grade but I used a rubberized paint once to paint a cracked plaster ceiling, overpainting with normal paint .. and it worked very well.

    I suspect that the cracks will reappear if you attempt to fill them. Mine did!

    Cheers Antiskeptic.
    I had a feeling I'd be on a hiding to nothing to fill them.

    Chase out a little fill with tech 7 use a damp sponge to tap over the tech 7 to try match the render finish and paint.

    Get a tube of exterior caulk ( about 6 euro), go over top of crack then use your finger to smooth out. You can then paint over if you want but cracks won't reappear as no more moisture can get in. ( Make sure wall is thoroughly dry first)
