Sliding in the floor unfinished was not too difficult but you might have a problem with the tabs and slots. Use a mallet to tap in your tabs, after they are aligned correctly. Do not use glue until after the floor is in place. Trying to glue your floor before installation, will just create a dripping mess on your finished walls and floors.
After the floor is in place, run a bead of tacky glue along all the joints. This floor is interlocked into the center wall so it is not going anywhere. You do not need an excessive amounts of glue.
After the glue dries, you can go ahead and finish your floor. Turn the dollhouse upside down so you can paint the ceiling side. Since there are a lot of uneven peaks for the roof, you will need to place two objects under your dollhouse, that the attic floor can rest on, so it can sit upside down. I used two tubs of wallpaper paste.
I then very carefully painted the ceiling. It is more difficult to finish your flooring this way but believe me, you will be very happy that you do not have to struggle trying to interlock a finished floor. As you can the raw wood is just soaking up the paint, expanding and warping in the process. I would not have wanted to try and slide this swelling floor into such a tight space.
Now that the dollhouse is upside down and I am waiting for the ceiling to dry, it is the perfect time to add ceiling trim to the first floor.
