This drywall provides a layer of acoustic barrier to your home making it quiet and also the noise from inside your home will to go outside the walls. You can install this drywall over top of existing drywall. But if you are doing a new home or a new addition, you can just add it like you would regular drywall. It is that simple. You pick the brand you would like to use. Available in 3/4", 5/8" and 1/2" thickness you decide how much soundproofing you need. Once you do, that you are set to get started.
Step - 1 - Ready the Room
If you are installing over existing drywall, clean off all the walls and get everything out of your way. Having measured the room, you already have the sheets you need. be sure to have all electric cords, and such moved out of your way for safety sake.
Step - 2 - Installing the Soundproof Sheets
Put your boards up against either the bare wall or over top drywall that is existing. Make the edges fit as closely as possible. Edge them up together and screw them in place being careful not to start a screw into another one underneath. Do this all the way around the room until you come to the place you have to make a cut. Measure the width off with your measuring tape and using a straight edge mark the board to be cut. Score it with the utility knife and snap it in half keeping the left over for future use. Install all the boards around making sure to screw the heads in making a little dimple.
Step 3 - Taping and Mud
Now comes the taping part. This is easy. Just measure off the tape to the length you need and apply a thin layer of mud to make it stick to the joints. Tape where the two pieces meet to make one smooth wall. Now use the putty knife to apply a smooth layer of mud over the strips and smoothly as possible. This will have to set up over night to be sanded.
Step 4 - Finishing the Job
Now, depending on how you are going to finish the room you need to apply either mud all over the wall or the type of overlay you need. Orange peel is an easy one and adds texture to the wall along with being able to spray it on. Before you do this you need to sand down the jointed parts and make them even and smooth. Do this with a light touch so you don't go too deep. After you apply your topcoat, let it set overnight and dry. Now using the soundproof putty put a light sealant all around the edges of the top, bottom, and sides of the walls, anywhere there are edges. Even at the doors. Make it smooth with a smoothing tool. Now you are ready to paint .
