I'm thinking of buying an old stone cottage in North Wales to completely renovate from the ground up. I was intending to re-render all the outside and inside walls in lime to help it breathe and because I hate pebbledash which is what all the local builders use. However, someone told me plastering inside with lime will leave the house very cold and he suggested studding it all out, Kingspan insulation, vapour barrier and plasterboarding/skim. I can totally see the sense in what he says, but I just don't like the idea of plasterboard walls in an old traditional Welsh cottage.

So, is it not such a good idea to use lime inside and will it really leave it a lot colder? Also, is it necessary to go on a specialist lime plastering course because I've never used it before. The courses I've read about only seem to be one or two days but I'm sure there's a lot more to it than that!
 
keep it traditional i say and go on a lime course to get to know the product , you can read up a fair amount about it on the net and on here but you really need to be hands on with it .
 
I may have a windmill to do in liverpool soon 300 m2 of lime render come and work on that for free... save you paying for a course... also if you can sand and cement render then lime render shouldnt be a problem... just drying times between coats = 5 days minimum... protect from rain/frost etc. you can buy premixed NHL 3.5 for your job, just chuck in a mixer or you can get it bulk for £300.00 per tonne and mix yourself if lots of m2 to do if get it from here http://www.lime-mortars.com ask for colin he will keep you right

also render cottage it both inside and out with lime as it will breathe just do what everyone else does and use your central heating when needed :)
 
Trouble is these buildings were never designed for central heating or modern double galzed windows units and insulation ,so you might get a fair amount of surface mold behind curtains , sofa's and in bathrooms once things are dried out , just a heads up thats all .
 
That nhl 3.5 do you mix anything with it or just water?

Dont understand all this lime talk.
 
we used some lime stuff before and it comes ready mixed, you just have to knock it up in a mixer, i think it came from down devon or cornwall way.

you mix it with sand (washed ), google lime render and have a read up mate loads of info out there
 
you might want to think about introducing some sort of insulation or there's a good chance it'll be back on the market when its finished :mad: Old solid stone walls have no insulative qualities whatsoever. You say its dash already? then an external insulation system might be a good choice. l*m*-g***n do a good eco one or rockwool has some very good credentials too. that way you get to retain the authentic lime rendered(insulated) finish on the outside, and retain your solid walls inside. the thickness of stone when externally insulated will act as a heat sink(thermal mass) meaning it will retain heat for long periods in winter and also keep cool in summer thus providing a stable temperature all year round :)
 
An eco friendly lime insulated render ,god i wish id of thought of that ,is it any good goody ?
 
Many thanks for all the helpful advice guys.

Goody - I haven't got a cottage yet, I'm in the process of looking for one. I know Anglesey well and guarantee when I find one, it'll have lime/horsehair interior walls and either bare stone exterior walls or crappy pebbledash if one of the local cowboys has had a go at it ::)

Thanks for the offer Render Systems, I'd love to have a look at that job, although I'm currently based in Essex. Was in Liverpool last weekend funnily enough watching Everton give Man City a good spanking.
