to peppledash is faster and easyer than 2 coat render, so should be cheaper
How do you work that out? Edit: checked your profile and you're a pro builder! You telling me that you use one coat of render and dash into that?

I had a pebbledash house once. It had turned kind of grey with age. Looked horrid. Painted the whole thing (which was massively painful - really hard to get good coverage), it looked like stucco afterwards. If I'd had the money, I'd have flat rendered the lot and painted that.
Are you going for some sort of retro look?

Ha. No, the house was bought pebbledashed. One wall has bits of render/dash coming off so needs redoing. I don't really want to spend thousands just to make the other 3 walls look nice/match.Are you going for some sort of retro look?
Oh, the render upon which the pebbledash sits is coming away from the wall. Mostly, it's just cracks and when you tap the render it sounds hollow? A little bit has come off to reveal beige stuff. This is just below the eaves. There's signs of dampness (furry mould) on the inside of the wall near the ceiling. Presumable this is because water's getting through the cracks and bit that's come off? A lot of the front of the house sounds hollow but there are no other signs of damp.
Any thoughts?

Sounds like it has blown (lost it's mechanical key/adhesion to the wall). As you say, water will get behind and cause a potential damp problem. Also once the water is behind it and it freezes, the water expands, render fails/cracks/falls off.
Anything blown wants hacking off and renewing.
Your choices then are sand and cement render, sand and cement render dashed, monocouche (through coloured).

It's 3 days work for a spread and his mate. 1 day to hack off, 1 day to scratch, 1 day to float. (£250 per day?)
