Final Coat Professional Painting

One common feature to dress up the traditional square drywall corner is the use of bullnose corners, a rounded corner. Bullnose gives the corners a softer look and reduces the need for trimBroken Bullnose Corner in some instances. However, many homeowners who have this feature have also encountered difficulty after a period of time with the corner bead popping loose and leaving a very unsightly crack near the corner, thus negating the soft look desired which was the reason for using the bullnose in the first place!

The most common cause of the bullnose corner pulling loose is the way it is installed. Most installations call for a coat of topping compound placed on both corners. After that, the corner bead is simply placed onto the compound and then the corner gets skim-coated like a regular square corner bead. Nails or screws are usually only used at the ends of the bead. The topping compound is responsible for holding the bead in place. Far too often this application ends up looking like the corner pictured.
