DexDamp self-stick sound dampening sheets are an easy, effective way to reduce noise in cars, boats and homes.

  • General: Tacky mastic with paintable aluminium top-layer
  • Cost: $12 per sheet for ten or more, purchase here
  • Size: 12" x 24" x .078" sheets, .58psf
  • Odor: No toxic or noxious odors
  • Heat Resistance: Continuous exposure to 250° F. Dexdamp can be applied prior to any baking process up to 400° F. Self extinguishing per FMVSS 302.

As a general rule, metal or plastic surfaces may be suitable for DexDamp. Listed below are common damping situations.

  • VEHICLES 

    To reduce road & engine noise treat the floor pan, strut towers, firewall, doors, trunk, roof and dash panels.
  • STEREO SYSTEMS 

    Audio system performance can be improved by treating panels next to speakers or as part of a speaker enclosure.
  • PIPES & TUBING 

    Use as a wrap for metal or plastic as used in plumbing drains or hydraulic systems to muffle noise.
  • BOATS 

    May be used for bulkheads, decks, tanks, engine room ventilation ducting, fiberglass exhaust silencers & tubing.
peal and stick

DexDamp peel & stick sound dampening sheets could not be easier to use. Trim the DexDamp sheet to the desired shape with a scissors or knife. Then peel off the bottom layer to access the sticky side. Apply the sticky side directly to the surface being modified. That's it. Click here for additional tips.

Surface Preparation

For best results, surfaces should be clean, dry and free from grease, oil and dust. DexDamp has tackifying agents that help it to adhere to any substrate encountered in the assembly process.

Adhesion and Durability

DexDamp has demonstrated excellent adhesion to CRS, galvanized and galvanneal steel, ELPO and basecoat and clearcoat body panels.

Its outstanding adhesive performance allows it to maintain its position in the most demanding vertical and inverted applications, even at elevated paint bake temperatures. DexDamp maintains its acoustic and adhesive properties after subjection to the various test conditions used in the automotive industry.
