How to Build a Soundproof Partition Wall Part 3 How to Build a Soundproof Partition Wall Part 3
In Part 2 of this series on how to build a soundproof partition wall, you learned how to insulate the partition from sound. Now, you are almost finished, and the only thing really left to do is hang drywall and finish. So, the final part of the how-to guide will show how to do just that. Follow the simple instructions below to finish this project.
Step 1 - Measure and Cut Drywall
Measure the distance from the floor to the ceiling. Then, take a sheet of drywall and use the utility knives cut the bottom of the sheet so that it fits flush along the ceiling and the floor. If your home has standard 8 foot ceilings, you may not need to cut the drywall at all.
Step 2 - Attach Drywall to Partition Wall
Use the drywall screws or nails to attach the sheets of drywall to the innermost section of the partition wall. Butt the edge of the drywall flush up against the supporting adjacent wall, and secure the sheet to the studs. Complete this process until you have attached drywall along the entire length of the partition wall on both sides.
Step 3 - Apply Drywall Putty and Tape
Once although drywall is attached to the partition frame, use the putty knife to apply a drywall putty in between the seams of the sheets of drywall. Then apply the drywall tape and cover again with drywall putty. Allow the drywall putty to thoroughly dry before continuing. Also, use the putty knife to apply drywall on the nail or screw holes in the wall.
When applying drywall putty, try to make the application as smooth as possible. This will greatly reduce the amount of time you spend on sanding
Step 4 - Sand the Drywall
After the drywall putty has completely dried, take the sanding block and sand away rough edges and tried to smooth out the wall as much as possible. The more time you spend sanding the drywall, the better your finished wall will look.
Step 5 - Paint the Partition Wall
Apply a couple of coats of primer to the new soundproof partition wall. Once it dries, choose a paint color and paint the wall. Don't forget to lay down a drop cloth to help prevent a mess while painting.
Step 6 - Paint the Molding
While the paint on the new partition wall is drying, go ahead and measure the ceiling and floor molding (if you're using molding). Once you cut the molding, go ahead and paint it the color of your choice, or you may choose to apply a wood stain or varnish to the molding.
Step 7 - Attach the Molding
Once the paint on the wall and the molding is dry, you can attach the molding to the top and bottom areas of the new partition wall using the hammer and some finishing nails.
