Once the shelf is installed, use wood putty to fill the nail holes and any gaps between your mitres. Use caulking to fill any gaps between the wall and shelf. Fill up those shelves and enjoy your new modern floating shelves!Aug 17, 2017
How do you stack two bookcases?
Place three C-clamps spanning across both bookcases evenly spaced vertically from top to bottom. One side of the clamps will fit in one bookcase, and the other side will fit into the other bookcase. Tighten the clamps securely to bond the two bookcases together.
How do you stack bookshelves?
Stack them horizontally, or shelve most vertically and then stick some horizontally on top of their new vertical buddies. Use your shelves for support. If you've run out of space on the bookshelves themselves, stack books next to them, using the bookcases as support.Sep 11, 2017
