According to one Suffolk expert, limewash was not used inside homes. If true, then we’ve been doing it wrongly for years. Instead distemper made from chalk and milk casein is said to have been the covering of choice, so this winter we’ve tried it. Continue reading “Distemper”
I’ve been wondering how best to redecorate a room whose surfaces are finished in old materials – clay and plaster – but which have been painted with modern emulsion. That may be creating a breathability problem.
Very modern emulsions are impermeable to moisture. Cruder basic emulsions have a certain amount of breathability, but it’s hard to tell which it is, looking at the result at least 30 years after it was last painted. So should the emulsion be removed? Continue reading “Limewash over emulsion paint “
I gather that there is questioning among some East Anglian lime specialists of the claim reported in the previous post that traditional hair mixes are significantly prone to failure.
As I mentioned, this is not about the well known deterioration of hair if it is left too long in a wet mix before being used, but about intrinsic faults in the hair, especially if it is imported. Continue reading “PS on lime”
One of the conditions for listed building consent was that the colour of the extension must match the yellow ochre limewash of the old building, so the simplest way to do that would be to use the same limewash mix again. Hollins, the architects, instead specified Keim in the listed building consent application, a mineral paint which has been on the market for well over 100 years, and was developed in Bavaria as a more durable substitute for limewash. I’d never heard of it before, but a web search shows it is widely known.
The wall repaired in 2009 was limewashed the following spring with a colour made up to our specification by Ted Ingleby, the well known traditional paint manufacturer of Glemsford, Suffolk, which he called Rodgers Flint. We asked him to match the very attractive colour of the render itself, which came from the sand we used. (We took it to him painted onto a flint). The recipe is on his file and we have continued to order it.
There turned out to be a bit of controversy over grades of limewash – one for the those into the detail of repairing old buildings. Ted is very keen on an ancient Suffolk recipe using tallow, which he markets for outdoor use. It can cover a wall effectively in three coats rather than five and is very waterproof, and has considerably better coverage and durability than some other versions of limewash. But various books we consulted advised against tallow as not breathable enough, and suggested linseed oil was better, or even plain limewash in sheltered positions. Three of our walls are very sheltered.
We decided to add new coats the following year, 2011, using Ted Ingleby’s interior limewash, with linseed oil, on the outside. Continue reading “Limewash”
