1. Cut Kinetics SRP isolation material to a width equal to 1/4‐inch less than planned floor system height.
2. Apply spray adhesive (such as Camie 363 High Strength Fast Tack Spray Adhesive), following manufactures directions, to one side of Kinetics SRP perimeter isolation material (alternatively double sided tape may be used).
3. Firmly adhere it to any wall or vertical position (including door frames) surrounding the perimeter of the Soundmatt installation area.
4. Adhere Kinetics SRP to any protrusions through the floor system including floor drains, columns, pipes, conduit, etc following steps 1‐3.
Note: Never attach the perimeter interface with nails, screws, or staples.
5. Lay Soundmatt over designated area, do not use adhesive, do not overlay or leave gaps between the sheets or at perimeter.
6. Do not tape the seams or joints.
7. Keep traffic on Soundmatt to an absolute minimum.
Note: Never attach the Soundmatt with nails, screws, or staples.
8a. Place a single layer of 6‐mil poly sheeting with 6 to 8‐inch overlap on top of Soundmatt and Kinetics SRP perimeter interface.
9a. Install mortar bed or lightweight concrete as directed by manufacturer.
a. Suggested thickness for mortar bed is between 1‐1/4 and 2‐inches, inclusive (TCA #F111‐96).
b. Suggested reinforcing is 2‐inch x 2‐inch x 16/16 gauge welded wire mesh (TCA #RF900‐96).
10a. Proceed to step 21.
8b. Place a single layer of moisture barrier such as Maxxon Moistop (or approved equal) with taped seams on top of Soundmatt and Kinetics SRP perimeter isolation board.
9b. Pour 1 1/2‐inch thick layer of Gypsum Concrete such as Maxxon Gyp‐Crete 2000, DuraCap, ThermaFloor, or Level‐Right (or approved equal).
10b. Proceed to step 21.
8c. Optionally, lay builders felt or 6‐mil poly sheeting with 6 to 8‐inch overlap on top of the Soundmatt. Do not adhere felt or sheeting to the Kinetics Soundmatt.
Note: Do not adhere or fasten the plywood to the Soundmatt.
9c. Lay down first layer of 1/2-inch thick plywood or OSB with joints staggered in relationship to Soundmatt joints.
10c. Trowel glue across the top of first layer of plywood or OSB.
11c. Lay down second layer of 1/2-inch thick plywood or OSB layer oriented 90 degrees and with joints staggered at least 12-inches in relationship to first plywood layer.
Note: Finished flooring manufacturers often require 1/8-inch gap between top layer of plywood or OSB sheets to allow for expansion
12c. Secure plywood or OSB layers together with 7/8-inch long screws spaced within 3-inches of the edges and spaced no greater than 8-inches in the field.
Note: Do not nail, screw, and/or staple into the Soundmatt with fasteners.
13c. Proceed to step 21.
8d. Roll out a layer of builders felt or 6‐mil poly sheeting with 6 to 8‐inch overlap over the Soundmatt.
9d. Lay down minimum 1/2‐inch thick reinforced cement backer board sheets with a 1/4‐inch gap between the units, offsetting the joints 8 to 10‐inches from the Soundmatt below.
10d. Snap chalk lines on the Kinetics Soundmatt marking the joint placement of the reinforced cement backer board sheets.
11d. Prepare a slurry of Thin‐Set mixed with Acrylic Mortar Admix to proper consistency.
12d. Dip 2.5‐inch or wider high strength polymer coated fiberglass tape into the slurry and center it on chalk lines.
13d. Apply more slurry on top of the tape.
14d. Trowel a light skim coat of the slurry approximately 1 1/2‐inch wide around the perimeter of the bottom side of the reinforced cement backer.
15d. Position the reinforced cement backer board sheets over the slurried tape leaving a 1/4‐inch gap between boards.
16d. Bond the reinforced cement backer board sheets to the tape by walking on the edges of the sheets to force slurry into the joint gap. Fill the remainder of the 1/4" gap with slurry from the top of the joint.
Note: Do not apply excessive pressure when filling the joint from the top. Otherwise a ridge will develop on the underside of the sheets, creating an uneven surface.
17d. Lay another strip of fiberglass tape directly over the joint.
18d. Trowel a very thin skim coat of Thin‐Set mixed with Acrylic Mortar over the tape creating a smooth surface for bonding the tile. If the reinforced cement backer board sheets are uneven prior to the joint bond taking set, place light loads (box of tile, etc.) at different locations to level the panels.
19d. Do not allow traffic on the reinforced cement backer board surface for at least 24 hours; 48‐72 hours may be required depending on ambient temperature and humidity.
Note: The proper taping of the underneath side, edge bonding, and taping is essential to the structural strength of the reinforced cement backer boards within the sound‐rated floor system.
20d. Proceed to step 21.
21. Install finish flooring according to manufacturer’s directions.
a. DO NOT install finish flooring over Kinetics SRP perimeter isolation material.
b. DO NOT allow hard grout to come in contact with the wall.
22. Trim Kinetics SRP perimeter isolation material to top of floor system.
23. Seal the perimeter with a permanently resilient acoustical or elastomeric sealant.
24. Install molding around perimeter of floor while maintaining an 1/8 inch gap between the molding and the finished floor.
Soundmatt is a 5/16" (8 mm) thick underlayment comprised of custom molded glass fibers. After installing the appropriate isolated subflooring, it can be used under most floor surfaces such as hardwood flooring, ceramic tile, quarry tile, marble, wood parquet, and vinyl tile.
Kinetics Soundmatt is the perfect solution for projects where thin underlayments that allow for direct attachment of finished floor materials will not meet performance goals. Soundmatt is more resilient than these products, which translates to better impact noise control.
