Anyone have a good spot to recommend for sourcing non-hydraulic lime putty, boiled linseed oil, other natural paint and finish ingredients? I'm not too far from Portland and plan on picking up pigment ingredients from Georgie's Ceramics but not having much luck nosing out supplies.
Getting myself back to this project. Thanks for your responses!
Tel, I have hydrated lime, but i was under the impression it's not as good quality for painting as a non-hydraulic. Has your experience been otherwise? I'm thinking to make up a limewash for the top bar bee hives I'm constructing with lime, boiled linseed, and pigment. With your bee knowledge do you think that would seal the hives enough? This is my first dive into beekeeping. Given that I'd have to reapply a limewash eventually would that disturb the bee too much?
I don't believe that hydrated lime is hydraulic unless some sort of pozzolan is mixed in. despite my best attempts, though, I'm still an amateur concerning lime.
I think your mixture would work to preserve your beehive's wood. that's not the only consideration, though. you also need to decide how vapor permeable you want the wood to be. a small amount of linseed oil probably won't totally prevent the wood from breathing, but I would personally be a little wary of using too much oil in our rather damp climate. limewash without any binder should breath just fine, and if you're not too rough about it, reapplication of anything non-toxic shouldn't bother the bees much. doing it when they're dormant would probably be the best bet.
I should mention that plenty of folks believe condensation in a hive can be beneficial, in which case oil would be great.
when I finish up the hives I'm working on, one will get a limewash.
