Lead-lined drywall has a sheet of lead built into it that blocks out radiation. It is commonly used in hospitals and clinical settings that use equipment that produces radiation. You can also use it when installing the walls in your home if you have need for such equipment. The lead blocks radiation from leaving the room. If you need to use drywall that offers protection from radiation, you will find the installation process similar to installing standard drywall.
Instructions
1. Measure the space between the center of one stud to the center of the next stud. In general, the studs will measure either 18 or 24 inches apart. Select the appropriate drywall for your stud spacing.
2. Position the first sheet of drywall against the studs in the bottom corner of the wall and secure the drywall to the studs with 2 1/2-inch drywall screws and an electric drill with a screwdriver tip. Drive the screws approximately every 6 inches down each stud. Countersink the screws slightly so you can cover them later.
3. Place each additional bottom sheet of lined drywall along the bottom row of the room in the same manner. If you come across a section of wall where the studs are spaced closer together, measure the distance between the studs and cut a piece of drywall to size with a utility knife then attach the drywall to the studs.
4. Measure the distance between the top of the first row of drywall and the ceiling joists. Cut drywall sheets to length then attach them to the wall the same way you installed each of the drywall sheets in the first row.
5. Apply a layer of drywall plaster to the seams of each drywall sheet and over each screw hole. Use a 4-inch trowel to ensure you apply an adequate amount of plaster to the seams.
6. Cut a piece of drywall tape to length then press the tape into the seams with the trowel. Add an additional layer of drywall plaster over the drywall tape. Allow 24 to 48 hours' drying time.
7. Sand the surface of the drywall plaster so it blends in with the surface of the drywall with a sanding block.
8. Sight down the wall once you are done sanding. If you see any high areas of plaster, sand them down. If you see any depressions in the wall, add additional plaster, wait for it to dry then sand it flat.
