When installing the attic floor of the dollhouse, follow these steps carefully. The floor uses the same locking mechanism as the rest of the dollhouse, and it's best to install it before finishing. Leaving the floor unfinished makes installation easier and prevents potential complications. While sliding in the unfinished floor, you might encounter challenges with tabs and slots. Use a mallet to gently tap the tabs into place after ensuring proper alignment. Avoid using glue before installation, as this can create messy drips on your finished surfaces.
Once the floor is correctly positioned, apply a thin line of tacky glue along the joints. The floor interlocks with the center wall, providing stability, so you won't need excessive amounts of adhesive. After the glue dries, you can complete the floor's finishing.
To paint the ceiling, carefully turn the dollhouse upside down. Because of the roof's uneven peaks, you'll need to support the attic floor using two objects — I used wallpaper paste tubs — to keep the dollhouse stable. Painting the ceiling this way can be challenging, but it prevents the difficulties of installing a pre-finished floor. The raw wood will absorb paint and potentially warp, which would make fitting it into a tight space nearly impossible.
While waiting for the ceiling to dry, you can take the opportunity to add trim to the first floor.
