Installation Instructions

  1. Confirm that you have upgraded your door from a hollow core door to a solid core door. Using our Gasket Seal Tape will not soundproof your door if you have a hollow core door, as sound will pass right through the door itself. 
  2. Inspect your door and identify where your gaps are located. Are your gaps along the door frame itself, the door jambs, or both?
  3. Measure your door frame along the hinge side and the latch side jambs or along the door frame itself. Write down your measurements. Go back and double check them. 
  4. Measure your Gasket Seal Tape out according to the measurements of your door frame. 
  5. Peel and stick your tape along the gaps so that your solid core door is 100% sealed.
  6. Use more Gasket Seal Tape at your discretion to achieve a 100% seal.
