Patch pebbledashing

[oldmandave]

Hi All

I'm after a bit of advice, had a new central heating system installed and when the old flue was removed this has left a 12" x 12" 'gap' in the white stone pebbledash. I can get the white chippings easy enough but can someone tell me what cement/sand mix I would use to have a white / grey finish.

thanks for the help

are you saying the render is white too? Tricky. White cement for certain, and you can get light coloured sands that won't tint the mix as much.. you're probably best off getting a bag of each and doing various ratio mixes, letting them dry and comparing to your walls. Every sand and cement is different and doing this now, with materials that are certainly different to the originals, means you'll have to have a bit of trial and error
