Surface Protection for Paulownia; Test Lanolin/Carnauba

Unread post Surface Protection for Paulownia; Test Lanolin/Carnauba
Yesterday I did some tests on small Paulownia rectangles, which had the largest sides cross to the grain (which should "soak" more water)
Since I do not want to glass, I tried Nothing, Lanolin double coated, Lanolin plus coat of Lanolin carnauba (10%), Double Lanolin carnauba (10%) and double Lanolin/Carnauba 25%.
I,m not yetz finished with the test and the analysis, but the total weight increase in percent after 2 hours watering was surprising. The double Lanolin had the highest increase, even heavier than the piece with no protection added, the Lanolin/Carnauba25% MIx the lowest. I still have to calculated the water soaked up (within the weight increase is the increase of the coat included).
For application I melted the ingredients, put them on and then put the entire piece into the microwave until bubbles appeared (Hoping to soak up as much as possible, but maybe I "cooked" it more out then in...).
Interestingly the final Lanolin/Carnauba 25% Mix went pretty hard after cooling down.
Still the final analysis is not done, but I think, I will give this mix a chance. The only question is how to apply it to the board, since my microwave is not big enough :). Actually I'm thinking of heating it way over 100°C(hoping not to destroy the complex ingredients) and put in on a warm surface, maybe sunrays are enough, if not I'm going to the next bakery and use an oven....
LAnolin and Carnauba where 100% pharmacy grade, For 500g Lanolin and 200g Carnauba I paid about 20$...

I read somewhere that even if lanolin absorbs water (emulgating) it will protect the wood; also I read that carnauba emugates, but with my pure carnauba I cannot verify this, I even put a peace of pure carnauba into a water pan, but it is still hard and the water pearls of. The rist of too much carnauba is that it gets to hard and slippery and need to be waxed with surfwax finally.

Final result is that the carnaubamix absorbed 9% of water, pure lanolin 28% and just paulownia 31%, the others in between. After 12 hours drying time, the weight of the carnauba mix did not change anymore, but remained at 2% more than original, the others took 24hours, all higher weight, than after coating. Only the pure paulownia dropped after 24 hours to its original weight.
I will give the carnauba/lanolin mix with 20% carnauba the chance to proof on my next board

Fresh Water, but I don't think, there will be differences, as we know that some guys use pure lanolin and they describe "that it will get sticky during water contact". This as far as I know is based on the emulgating process of lanolin, which absorbs water by itself. (But still protecting the wood) This is the reason for the weight increase in my tests too. The carnauba is a very hard wax, but heated it looks like its mixes and combines with the lanolin. And it hardens the tesulting mixture extremly. Yesterday I coated my new board and woorked the excess into the wood pores using a heat gun. The result looks quite good, although the real life test still too come. Unfortunately the next wave are at least 1000 miles away, so I have to wait for my holidays in July...

You may want to call World Paulownia Institute in Georgia. www.worldpaulownia.com I just got an
email from them that they have a harvest done and have long lengths of Paulownia in stock. They
have some nice stuff. They may know what to use? 1800-615-7306
