Ryan -

You should be looking at the world of lime paints. This would do real well in your area - plus they are environment friendly and kill all the moulds and germs.

Here is a British link I recently discovered <http://www.mikewye.co.uk/mikeprices.htm#video>

Also the English book by Jocasta Innes I have recommended many times "Applied Artistry" should be showing up used on abebooks.com by now.

As I have mentioned before, the long and amazing history of using lime in the decorative and construction arts, nearly everywhere in the world, is the history of adapting your local materials to your local need. Don't be afraid to use what is local and accessible, and then go from there, improving the process step by step, generation by generation. The history of lime if closely linked to the history of man.
