DOORSEAL

To install the door seal kit, simply follow these steps:

1) With the door closed, check the gaps between the door and the jamb on all sides. Consistent gaps of 1/8� work the best. You may need

to plane or cut down the door to achieve this gap size. The gap at the bottom of the door most likely is larger than the others. The threshold

will take up most of this gap, while the felt will seal the rest.

2) Remove door from jamb. Remove any hinges, locks or hardware.

3) Install a low-profile threshold (handicap type) centered under the (closed) door. Follow

the manufactures installation instructions when possible. See Fig-1.

To install the felt gasket wipers to the door, simply followthese steps:4) Cut or router a 1/4� wide x 1� deep slot in the center of the door edges around the

entire perimeter. Be sure to stop the slot short of each hinge and lock area. Cutting through

these areas will affect the reinstallation of the hinges and locks. Use the standard slot cut for

most applications. For more advanced applications, cut one of the other optional slot profiles

for a better �sweeping� action by the felt wiper. See Fig-2, 3 & 4.

5) Cut the felt strips to length to fit each slot. Use 1� felt on the top & sides. Use 1-1/4� felt

at the bottom. The felt is slightly stretchable (compressible)

to make fitting easier. You may need to cut the ends of the

felt at a slight angle (tapered) to fit the profile of the slot cut

around the hinge and lock areas. See Fig-4 & 5.

6) If adding a mass dampening layer to the surface of the

door, do so at this time. See installation guide.

7) Reinstall hinges, locks and other hardware.

8) Use white or carpenters glue for all adhesion applications.

9) With the door still removed (not hung), apply a generous bead of glue into the bottom of the slot cuts and insert the felt strips. Press the

felt all the way into the slots to make contact with the glue. Use 1� felt on the top & sides. Use 1-1/4� felt at the bottom. Wipe off any excess

glue. Carefully pull out the felt about a 1/16� to 1/8�. Do not let the glue dry.

10) Re-hang the door.

11) Carefully close the door to check the fit of the felt to the jambs and threshold. Keep the door

closed. Use a hat pin (or similar) to carefully pry the felt out to close the gap and make consistent

and tight contact to the jambs & threshold. You may wish to use a flashlight. This will help you see

the gaps� consistencies.

12) Let the glue completely cure (about 24 hours).

13) Carefully open the door to test the seal. The door may be difficult to open / close at first. The

felt will conform in time for a smoother operation.

14) Cut the self-stick foam pads to fit over each hinge plate on the door. Remove the backing and adhere.

MASSDAMPENING

To install the mass dampening to the door surface, simply follow these steps:

1) Remove the door for ease of application.

2) Layout and cut the moisture resistant sheetrock to fit the door. The sheetrock may be cut in any size / shape to allow for hardware and/or

windows, etc. Make sure to leave the proper clearances to allow for the overlap of the door jamb. The more surface coverage on the door the

better. See Fig-2. Note: If you know that the door handle to be used will extend another 1/2� - 5/8� you may reinstall it directly on the

sheetrock instead of cutting the sheetrock to fit around it.

3) Place Walldamp strips around the perimeter of where the sheetrock will be adhered. Use a rubber mallet to set the release adhesive. See

Fig-1.

4) Place Walldamp squares, spaced evenly (about 8� on-center or 50% coverage), within the Walldamp strip border. Use a rubber mallet to

set the release adhesive. See Fig-1.

5) Place a small dab (dime sized) of construction adhesive centered on each WallDamp square.

6) Set the sheetrock in place on the door and use ample pressure to set the adhesive. See Fig-2.

7) Optional -- Cut and attach trim moulding around the sheetrock edges to finish. If you do not wish to use moulding to trim the sheetrock,

coat the raw edges of the sheetrock with white or carpenters glue to seal the gypsum.

8) Paint / finish as desired.
