If you have not seen the new stronger joints on the hives that Shastina Millworks are using, take a second to watch this YouTube movie http://youtu.be/Jla7z9aehkQ.
We assemble them by gluing and stapling and then boiling them in a vat of paraffin and tree rosin for weatherproofing. The Weatherproofed 5 frame Deep Nucs are ready for year of use with no need for painting or maintenance. The finish darkens with age, but continues to stand up to sun and rain. They cannot be painted as the finish penetrates the wood.
