Removing pebble dash

buster3215

Hello,
I'm a newbie to Boards.ie and looking for some sound advice. I'm building a two story extension to old (pre 1880s) cottage and would like to remove the pebble dash to expose stone work on the gable wall that will be the inside wall of extension. Will it need to be chipped off with chisel or are there easier/quicker ways?

Generally the pebble dash is part of a thick layer of plaster which can be taken off with a bolster headed power hammer. How easy it will be to get off depends on the stone underneath and how even/uneven the surface was before the dash was put on, in other words how much of a key the dash has to the stone.

Thank you for advice. I reckon it has a very firm hold of the wall. I chisseled off about a two inch piece (the render is about two inches thick on lower part of wall but seems much thinner near roof) and there was rough stone behind it. I was thinking i could do as you suggest and then shot/sand blast the rest. What would you think?

A Kango with a 3 or 4 inch spade bit would be the handiest way

as others said with chisel or better still small kango with wide chisel.
seems your best option but on cleaning after if shot blast or sand blast will clean ok but this will leave stone with tiny holes that though maybe ok to eye
quickly gather every speck of dust and very difficult keep clean. instead try power wash with water, you will need whats called turbo nozzel to remove
and will take time but get far better finish afterwards
