Step 1Brush off loose dust; save any big pieces.
Step 2Spread glue thinly and to the edge of broken surfaces.
Step 3Fit the pieces together as well as possible. Add back any loose chips, but make sure the edge is smooth.
Step 4Allow to dry.
Step 5Use household spackle to fill the crack, smoothing with your fingertips when wet and with an emery board when dry. (Spackle contracts as it dries, so you may need to repeat this step.)
Step 6Mix acrylic paint to match (remember, it dries a bit darker) and dab on.
