Anybody had a good external render applied to their house? Specifically the pigment/coloured type that you don’t have to paint?

Our current extension has traditional cement render that is overpainted. I think a combination of warm extension plus the render being on a cold north facing wall is resulting in the render failing badly (paint coming off and cement shearing off in thick slices).

Probably wasn’t done properly application/mix, in the first place. I would stick with a proper sand cement lime waterproofed, mix. Knock off, rake out, hard cane brush, hose down, then apply scratch coat, 5.1.1 then render 6.1.1 and bead up. Finally apply wet dash.. (roughcast)and paint. If done correctly it should last around 100 years👍 I won’t use the new systems they are no good for our climate imo and get dirty very quickly. The old ways are best👍👍

I agree , done well it should last decades

BUT finding a good builder that will do it well is another thing ,
you know what builders are like

a plus side for modern systems is the external insulation BUT...
it needs doing well and you know what builders are like

I think there's a 66% grant for external insulation, depending on criteria ,if all that "free" taxpayer's money hasn't been wasted yet
