Victorian semi, large south facing wall, smooth rendered and painted. Has some cracks that need repairing before I repaint it. The cracks aren't huge, 1-2mm wide, probably full depth of render. Just caused by natural movement from the heat of the sun, most of the neighbours walls have the same problem, and surveyor says nothing to be concerned about. No point in filling with mortar, it will just crack again.
Was thinking of doing the following:
Brush out any loose render, dust etc Apply some stabilising solution/sealant, or maybe diluted pva? When dry fill with paintable flexible frame sealant? Use wet sponge to blend in and slightly stipple the surface Paint with regular Sandtex or similar.
Does this seem reasonable, or any better suggestions?
