Sound Shark Underlayment and the flooring material must acclimatize, in their sealed packaging, in the room where they are installed for at least 48 hours, at temperature of at least 65ºF.

Before starting Installation make sure the sub floor is permanently dry and free of dirt, dust, grease and other foreign matter.

Sub floor should be properly leveled, structurally sound and clean. Plywood sub flooring should be of a good grade.  Variations in floor level over 1/8” within 3 feet span should be leveled before installing underlayment.  Any nails or other protrusions should be pounded flat or removed.

Inspect concrete sub floor for any open cracks and fill with a high grade patch.  Remove any excess concrete lumps or residue that may interfere with the installation of Sound Shark.  The concrete slab should be permanently dry, apply a good quality concrete waterproof sealer or install a 4 mil vapor barrier.

Start in a corner and roll out Sound Shark. Cut the Sound Shark to maintain a 1/4” gap from the wall. Continue to rolling out Sound Shark adjacent to the last row until the entire area is covered. Make sure the edges are tightly butted together, both side by side & end by end.  If desired a good quality duct tape can be used to cover the seams. Install floated laminate or engineered hardwood flooring per manufacturers written instructions.  The perimeter gap can be filled with Sound Seal acoustic caulk.  Hold trim board 1/16” off floor to avoid flanking paths.

Note: When using Sound Shark in glue down installation it is important to note that the underlayment needs to be glued to the sub floor.  Always used the same adhesive to bond the rubber to the sub floor and the wood to the rubber.  Please insure that you followed all prep work for concrete slabs (see above).  Recommended adhesive: Sika T-55, Sika-35, Dri Tac 7600, Chemrex CX-941.  Use 1/8” x 1/8” x 3/16” V– notched trowel.  Start in a corner and roll out Sound Shark.  Cut the Sound Shark to maintain a 1/4” gap from the walls. Roll up the roll half way and apply adhesive on exposed area, roll back over adhesive flat trowel any air pockets, continue with other side the same way.  Continue rolling out and gluing down Sound Shark the same manner until the entire area is covered .  Make sure the edges are tightly butted together, both side by side & end by end. Use a 50—100 lb roller to fully bond Sound Shark to sub floor. After 24 hours follow manufacturers written instructions for gluing engineered hardwood to Sound Shark.  Hold trim board 1/16” off floor to avoid flanking paths.
