Dexdamp soundproofing is an excellent way to reduce noise and vibration. Dexdamp can be applied to metal or PVC conduits and automotive floor boards, headliners, trunks, door panels or engine fire walls. Note: Dexdamp 423 and SikaDamp 630 are the same product under different labels.
Dexdamp Soundproofing For Plumbing, Boats & Vehicles
Dexdamp is a pressure sensitive elastomeric vibration damping material. How's that for a mouthful? In plain English, it's a flexible, peel and stick sheet which can be applied to a variety of surfaces to reduce vibration and noise. Best of all it's less expensive than Dynamat.
Dexdamp's damping material is covered with a thin aluminum foil layer which improves performance and provides a paintable, finished surface. Ordinary film adhesives can fail if the bonding surface is not perfectly clean, especially on vertical surfaces. Dexdamp is different. It will bond to almost anything, even oily metallic surfaces.

Soundproof Water Pipes & Soundproof Drainage Pipes
Dexdamp sheets dramatically reduce noise associated with plumbing in condos, houses, apartments and office buildings.
The peel strength of Dexdamp easily outperforms conventional felted asphalt dampers and does so at a lower weight per-unit area. The super adhesion and conformability of Dexdamp results in maximum surface contact, critical for high performance damping.
The construction industry has been using Dexdamp for years. It's an excellent way to reduce or eliminate unwanted noise in plumbing pipes and sewage lines. The flexible peel and stick sheets can be cut to size and molded to any shape. Here's a step-by-step "how to" guide for soundproofing water pipes, sewage lines and plumbing conduits using Dexdamp.
Without removing Dexdamp's protective backing, align a sheet lengthwise along the pipe or conduit. Wrap it around the pipe.
In this example, a vertically aligned Dexdamp sound dampening sheet is not wide enough to wrap around the entire pipe.
If the sheet is not wide enough — if there's a gap in coverage — rotate the sheet 90° in either direction to better cover the pipe.
Without removing the protective backing, check the reoriented sound dampening sheet again for fit by wrapping it around the pipe.
After determining the sheet fully covers the pipe, you may trim off any excess material using a scissors.
Peel off the protective backing covering the adhesive. The sticky side will adhere to almost anything.
Press the sticky side of the sheet onto the pipe. Wrap the sheet around the pipe until it's fully covered.
Repeat the proceedure using additional sheets until the pipe is covered top to bottom. Couldn't be easier!
You don't have to be a construction professional to install Dexdamp. The one foot by two foot peel and stick sheets are easy to install. You'll be amazed how well they work. Compare Dexdamp to Dynamat or Dynamat Xtreme. Why spend more for Dynamat?
Quieting 2014 Scion tC
Scion's sporty blend of value and style has proved popular with young people. While the automotive media has generally given the Scion family of vehicles good reviews, some complain they can be a little noisy.
Instead of complaining about the noise, the owner of this brand new Scion had us do something about it.

A Quiet Ride From Now On
Dexdamp auto soundproofing sheets are perfect for this sort of thing. They're an effective and affordable method of quieting the interior of any vehicle. Applying sheets to the floor board and ceiling reduces road noise. Carpeting the front cabin and firewall with Dexdamp muffles engine noise.
When we finished, the car owner drove away in a car that looked like a Scion but sounded like a Silver Spirit.
Repairing Gas Spill Damage
Hauling gasoline inside a car is extremely dangerous. Static electricity or an open flame can ignite accumulated fumes and trigger an explosion. Fortunately, when a fuel canister tipped over on the back seat of this 2008 Subaru Outback there was no explosion. But, the spilled gasoline trashed the seat foam and carpet, then turned the soundproofing into slimy goo.
After we stripped and scrubbed the interior, the owner wondered if it was necessary to replace the damaged soundproofing. It hadn't been very effective; the car was noisy. We suggested a better alternative: sheet the floor pan with Dexdamp auto soundproofing. Dexdamp is not only affordable, it's far more effective than the standard stuff carmakers install on the assembly line.
The owner liked the idea, so we installed Dexdamp from firewall to tailgate.

In addition to installing better soundproofing, we saved the owner a ton of money by triple-washing the carpet and seat cover with a cleaner/fungicide instead of ordering expensive replacement sets. We also tracked-down used seat foam — less than half the cost of brand new foam. As it turned out, the owner drove off with a much cleaner, quieter car than before the accident.
Turning Down The Volume
The F-150's rich, baritone engine rumble is so desirable that Ford actually "augments" engine noise in some 2015 models, according to this report in Road & Track, "The final engine-downsizing complaint—that a V6, no matter how powerful, can't sound like a V8—is dead, thanks to Ford....under hard acceleration, the speakers play a V8 soundtrack over what little you hear of the turbocharged 2.7- and 3.5-liter EcoBoost sixes."
But, not everybody's into engine blast (real or enhanced). When you want a quieter ride, Mac's can help. The sound-dampening work we completed inside this 2014 F-150 Tremor tamed the truck's excessive noise.

Soundproofing Side Panels
In addition to engine roar, the owner complained of excessive road noise and a loud exhaust system. To do the job right, we first had to remove the center cabin console then strip the seats, padding and carpet. With access to the floor pan, side panels and headliner, our specially trained technicians went to work.
Dexdamp is ideal for this sort of project. These are flexible, peel and stick sheets custom-cut to cover almost any surface. The primary sound dampening material in Dexdamp is covered with an additional layer of performance-enhancing aluminum foil. When properly installed, the sheets reduce noise and vibration. In addition to muffling noise, the ride feels more "solid" with Dexdamp.

Cuts Cabin Noise By 50%
We fastened five sheets of Dexdamp auto soundproofing to the cabin roof, then carpeted the back and side panels with ten more sheets. It took an additional twenty to cover the floor pan and remaining interior surfaces.
Results vary based on vehicle design and the number of Dexdamp sheets installed, but in this case Dexdamp made a big difference. The owner reports a much better ride — up to sixty percent quieter!
Subaru Rides Like Mercedes
One of our customers was kind enough to pass along this compliment:
"You did a superb job on our old Impreza WRX wagon. Soundproofed and new leather seat covers. A trusty and fun old car now feels a lot better than it did when it was new. Seats are way more comfortable. It feels more solidly built, as well as way quieter. Drives like a WRX, rides like a Mercedes." — James M.
Thanks James! The work we did on your Subaru proves again how great a car can drive when it's been soundproofed. Here are some pics of the soundproofing we installed before restoring the interior.

As James discovered, when you upgrade your vehicle with new seat covers and soundproofing, it's almost like buying a brand new car at a fraction of the cost.
Quieting A Classic Convertible
The 1967 Barracuda convertible is a classic collector car. This one is in mint condition, but the ride can be a little noisy. A convertible is never going to be whisper-quiet, but Dexdamp sound dampening sheets can make a difference even in a ragtop. After carpeting the floor with Dexdamp, the owner reports a twenty percent reduction in road noise.
