Last weekend we got the insulation cut and fitted, screwed down the subfloor, and trimmed it to final diameter. This morning we put the remaining materials on the subfloor and covered it all with a big tarp. Good thing - it's been raining steadily most of the afternoon. Probably no more work will be accomplished till next week.
2/3 today I applied the waterproofing. I was not confident, because the "transparent" waterproofing used on some previous redwood decks tended to turn the wood yellowish. This is a different brand, and great googly moogly! It turned out really nice!
1/3 Yesterday I cleaned all the stuff off of the office yurt deck and pressure washed it. It looks pretty good!
