    I'm looking to repair a section of wet pebble dash on an old farmhouse. Any ideas on the mix to use (gravel/cement/lime)?

    You can get ready mixed bags of wet dash from 25kgs to ton bags. Saves a lot of messing about if just a little job. If the repair is back to the brick/block/stonework, clean the background of loose material. If the background is smooth you may need to give it a scud coat/scratch coat before rendering. Leave this render about 1/4" behind the existing roughcast.

    If you need to mix it yourself ....... Sand:Cement:Hydrated Lime:Stones ........ 9:3:1:Stones to suit the existing. Make a little batch initially ....... you can always add/subtract to match.

    You can use a drill for mixing as it's important to NOT have any lumps.

    Let us know how you get on.

    I did a new house with this but it be very hard to match old with new... For the new house i bought white sand and cement/lime in bags for plaster under... then the dash was mixed with white chips... I remember the plasterer telling me that in the old days the stones had to be steeped... ask the oldest plasterer you can find...
