  • 8″ concrete slab with insulated acoustical drop ceiling below and laminated hardwood flooring on top: IIC = 58 | STC = 58
  • Meets 1 hour fire resistance floor test complying to ASTM E119-12.

Application Instructions

  1. Position STOMP with the Mass Loaded Vinyl (black) side down onto the floor for hard surfaces such as ceramic tile or wood flooring. Position STOMP with the Mass Loaded Vinyl (black) side up for installation of vinyl or resilient flooring.
  2. Place edge to edge multiple pieces of STOMP to complete the coverage of the room being treated.
  3. Add desired flooring on top of STOMP as per recommended installation techniques.
    • Carpet and vinyl layers can go directly on top.
    • Wood floors can be nailed directly on top.
    • Laminate floors can be floated directly on top.
    • Ceramic and other hard tile surface floors can have the adhesive compound added to the top surface of STOMP – then add ceramic tile to complete the job.

IMPORTANT NOTE: For ceramic and other hard surface tile floor installations be sure to
use an epoxy fortified adhesive and grout system.
