DIY: Covering a Recessed Lighting Fixture

Recessed lighting fixtures can be covered with a piece of drywall and drywall compound. A 1 by 2 is required along with drywall screws, drill, drill bit, drywall compound and a 12 inch drywall knife.

Preparation

Turn off the electricity to the recessed lighting. Remove the light fixture from the hole. Measure the diameter of the opening. Cut a 1 by 2 inch board 4 inches longer than the diameter of the opening.

Bridging the Void

Place the 1 x 2 inch board inside the recessed light opening. Center the board so 2 inches extend on each side of the opening. Secure the board to the ceiling using one drywall screw to hold each end. Cut a circle from a piece of drywall that will fit in the hole. Insert the drywall circle into the hole and attach it to the 1 x 2 cross beam to hold into place.

Finishing the Ceiling

Attach the drywall tape to the ceiling around the circle. Place drywall compound around the circle and over the tape using the 12 inch drywall knife. Let the drywall compound dry and place a second coat over the area making sure to feather it into the surrounding surface. Let the second coat of drywall compound dry then sand. Apply a third layer of drywall compound if necessary and repeat the drying and sanding process. Finish by painting the area.

Comparison

Covering a recessed light fixture is the same as the process for fixing a hole in the wall. The hole in the wall is fixed by cutting a rectangular or square shape around the hole. This makes it easier for insertion of a new piece of drywall. Two braces will need to be inserted if the hole is over 12 inches in width. The braces need to cut 2 inches wider than the opening and secured with drywall screws.

Summary

Basic knowledge of drywall techniques will help when covering the hole where a recessed light is removed. It is necessary that the first coat of drywall compound that is placed over the drywall tape is thin. This helps the drywall compound to dry more quickly and to set the drywall tape in place. The second and third coat are added in thin layers to prevent cracking. Avoid putting on a thick layer of drywall compound. A heavy coating will crack and cause unnecessary work.
