If during a renovation or home repair you moved the ventilation in your ceiling, you need to seal up the old register vent so you do not have a gaping hole in your ceiling. Fortunately, you can seal up the vent in a way that will make it look like the vent was never there. Expect the process to take several days to complete. Therefore, this makes for a great weekend project.
Instructions
1. Remove the screws that secure the register vent to the ceiling and then discard the old vent.
2. Cut a patch of drywall with a utility knife slightly larger than the hole for the register vent.
3. Place the patch over the hole in the ceiling and then trace it with a pencil. Mark one side of the patch so you know place the patch once you cut the hole.
4. Cut along the scribed line in the ceiling with a keyhole saw. Stay as close to the line as possible to minimize the gap between the patch and the ceiling.
5. Cut two pieces of 1-by-1-inch lumber approximately 4 inches longer than the opening in the ceiling.
6. Apply construction adhesive to one side of the boards and then place the boards up into the ceiling and press the glued sides against the backside of the ceiling. Secure the boards in place by driving drywall screw up through the ceiling and into each end of the wooden boards. Countersink the screw heads into the ceiling slightly.
7. Place the drywall patch into the ceiling and press it against the boards. Secure the patch to the boards in the ceiling with drywall screws. Again, countersink the screws.
8. Apply a layer of drywall plaster around the seam between the ceiling and patch and over the screws.
9. Press drywall tape over the plaster with your putty knife and then add a layer of drywall plaster over the tape. Allow 24 hours drying time.
10. Sand the surface of the drywall plaster so the edges of the plaster blend with the ceiling. Take your time with this to get it right. Wipe the ceiling down with a tack cloth.
11. Pant the ceiling with color-matched paint that matches the current paint on the ceiling. Use a paint roller to apply the paint.
