Lime whitewash

[Kris5902]

You could consider covering the outside with a water repellent finish of some sort?

Also, from what I’ve read you want to apply your lime whitewash in as dry of conditions as possible, wood is porous and will absorb the moisture in the wash. Let everything dry out as thoroughly as possible before you apply a second coat, lots of air circulation as the moisture from the wash needs to evaporate out of the wood completely, leaving the lime behind. It’s sort of like brining a turkey or marinating meat... salt and water/the marinade is absorbed into the meat, and then leeches out, leaving some of the salt or marinade inside.

Thanks Kris5902. Maybe I should put a fan in there to help dry it. It probably didn’t dry all the way before the rain came. I think I will mix more lime in also to make it thicker and use less water.
