When installing baseboards, crown molding ("moulding") and chair rails, it's tempting to cut 45-degree miters at the corners and hope for a sure fit. The problem is that most walls aren't square. Joining two 45-cut molding pieces may give you a square joint, but a square joint may not work for your crazy corner. In fact, it seems like every wall is just a “hair” out of square. This problem could be due to a framing error or a buildup of drywall compound in the corner. But even a perfect miter...

If it doesn't come off easy, use a sponge to wet the area on both sides before you scrape it. After this, use either fiberglass tape or paper tape with drywall joint compound. If you use the compound and paper tape, you have to put a thin layer of compound down before you place the tape over it. Let ...
