With the prep work finally done after what seemed like ages, it was time for a new subfloor!
We bought our plywood from a local lumberyard – 1/2″ 5-ply exterior-grade sheathing, cured and stored indoors, flat and dry. We opted against marine grade and instead are treating it with a borate-based pretreatment from Nisus Corporation to prevent mold, mildew and insect infestation. We finished up the protection by sealing the bottom and edges with low-odor, oil-based primer. Our actual finished flooring is going to be glue-down 12″ x 24″ cork tiles.
Today we borrowed a family member’s wood shop to cut the curved pieces of our floor. If there’s anything we’ve learned from renovating a 100-year-old house and now this nearly 50-year-old Airstream, it’s to never assume anything that’s old is square, plumb or level! Even after careful measurements and templates, we still had a lot of adjustments to make when the time came to install it!
We jacked the trailer shell up off the frame a few inches to be able to get the new flooring between the two. It was a little terrifying watching all that aluminum teetering around in the air, but she’s safely back down on the floor and frame now. Installation took two days, several people, lots of wiggling, cursing, adjustments with a sander and jigsaw, but it’s in!
We’re so excited just to be able to walk in our trailer again for the first time in many months. It was also our dogs’ first time ever in the trailer, and my first time sitting or laying down on the floor!
