Some of the external walls of my house are showing signs of wear and tear,
most of which can be freshened up wityh a good coat of paint. But I have
noticed some of the roughcast has started to crack in some places. It
doesn't seem to have got behind the mortar, which is still solid on the
wall, but I am keen to address the issue and prevent the problem
Can anyone advise on the best way to seal these (cosmetic) cracks in the
roughcast? I've heardmention of some sort of solvent spray which seals the
cracks, but elsewhere its been said that they need to be patched up with
fresh mortar prior to painting.
Could anyone with experience of this letme know what my options are, and
what the best products to use are?
