Hoping someone can help... I’ve had old window/ door patched in with roughcast. As you can see from photo the new roughcast does not match old one as grey render has been used ... I also know I’m never going to have an exact colour match as old roughcast is quite dirty. The roughcaster advised he had to use grey render as the coloured render I have is no longer available. Looking online I can see a couple of render dry dash receivers that could be a possible match however I was wondering if anyone would know what colour of render has been used for the old rough cast as my roughcaster has offered to redo the job if I can source correct one. Thanks
