So, workshop build is still ongoing, but (despite the picture showing an absolute carnage of mess) things are getting closer. I've got the parking bay (where that pesky boat will move forward into) walls sealed and concrete densified and sealed, as well as the studio all up and running for Amy. Remaining (major) things:
1. Seal walls of the shop area
2. Densify and seal concrete floors of shop area (probably gonna have to do this in two chunks, but we'll see how it goes).
3. Finish installing remaining 3 light fixtures, finish electric outlets in shop area
4. Move in the airplane parts
5. Continue building the plane
6. Engineer clever storage mechanism for future completed plane parts
For those interested, some products used:
-Wall sealer: General Finishes Gloss and Flat - We've been using a roller to apply this, we do a gloss coat first and then the flat-coat after. It's been a great product so far, goes on nicely, isn't much more expensive than the big-box store poly products and the performance is MUCH better (less drips, less entrained air bubbles, etc.)
-Concrete Densifier and Sealer: Using two products here, Ghostshield Lithi-tek 4500 (this is the densifier, I'm using it at half strength and applying with a low-pressure sprayer). Since this is slab on grade, the densifier should help a bit with potential freeze/thaw issues as well as getting a bit of additional hardness into the concrete. After 24hrs, I then apply two wet-on-wet coats coats of Ghostshield Siloxa-tek 8510 - let that dry down for an hour or so, and then wipe up any remaining wet product. The Siloxa-tek product is solvent-based and provides oil and water resistance. So far, it's been high-performing on the floors I've completed, but time will tell as to it's durability (but so far, the water is beading up as though it was a freshly waxed car - so that's a good sign). The other plus with this sealer (at least for me) is that it has zero surface modification (so no gloss, no loss in traction, etc).
