Hi,
We are looking to tear off the crumbling pebble dash on the front of our victorian terrace in north London and either repoint the brickwork (if it's in good enough shape) or put a render over it.
If it's just repointing, we will obviously go with a lime mortar but we've had quotes from numerous contractors who claim that a silicone render will be absolutely fine as the are breathable. I'm finding it pretty hard to get a solid answer on whether the breathability of modern silicone renders will be sufficient for our house to breathe and avoid damp. One supplier who i contacted told me that "neither lime or silicone will cause damp but lime is better for older properties" which i found incredibly unhelpful as an answer. There are a few lime renderers who work in our area but obviously quotes for installation are higher (and maintenance is a consideration).
Is anyone able to give advice , or has put a silicone render on their victorian terrace? Any issues with damp?
Thanks
Jono
