Product Description

3M™ Sound Reduction Mat suppresses road noise, sound system vibrations, rattles, and other distracting sounds. Installing this sound deadening pad makes a car or truck more pleasant to ride in by helping block noise for a quieter ride. This mat may be used as a replacement for factory installed sound deadening pads or as newly installed sound reduction pad. Self-adhesive material is easy to install on bare, primed, or painted metal surfaces. Easy-to-cut material may be applied to vehicle floor pans, engine compartments, hoods, deck lids, inside doors, and on body panels. Road tested to the high standards of the European market, this mat fits easily around a variety of shapes and has a center perforation for easy door panel installation. Sound reduction pad only requires simple household tools such as a scissors for installation.

Sound reduction mat comes in a box with 2.5 square feet of material, which should be applied at temperatures of 40°F (5°C) and above. Ease of conformability increases at higher temperatures.  Installation is an easy 6-step process: 1) Prepare area by removing any carpeting, lining, and/or panels to expose metal substrate, 2) Clean the surface with rubbing alcohol and let dry and ensure surface is free of oil, dust, and debris, 3) Using standard household scissors cut the 3M™ Sound Reduction Mat to fit the size of the desired area, 4) Peel and discard the yellow liner off the back of the mat, 5) Using even pressure, carefully conform and firmly apply to the surface. If additional conformity is needed, use a heat gun or blow dryer to heat the mat to 95°F (35°C) to 115°F (46°C), and 6) Return panels, carpeting, or lining to original position.

Very easy to apply.

This might be a great product if you've had experience with something like it before, but I'm going to leave this one to the professionals.

This is not to say that this 3M sound reduction mat doesn't work, only that there may not be enough material to make any difference.

This 3M Sound Reduction Mat comes in a roll measuring 19-11/16 X 19-5/8 inches. There is a perforation in the middle for easy separation into two halves. The mat is backed with adhesive for easy installation. The material looks like rubber but it is very brittle. The roll came in a less than perfect condition. A small piece was missing at the corner and there was an inch-long tear at one of the edges. I put the two halves under the front floor mats of my 16-year-old compact sedan. Frankly, I couldn't tell any difference in road noise before and after. This is not to say that this 3M sound reduction mat doesn't work, only that there may not be enough material to make any difference.

Muffling road noise in an old car is a big job. It involves pulling the door panels to get to the backside of the metal doors and removing floor mats, carpet and seats to get to the floor pan in order to install sound absorbing material like this 3M mat. The job involves a lot of time and material, much more than an average car owner can handle. In my opinion, it is a job best suited for a professional body shop.

What's in the box?

* One sound-deadening sheet approximately 5/32" thick. You can use it as one mat, 19 11/16" by 19 11/16", or as two smaller mats (it has a perforation down the middle).
* Instructions.

In general, I find 3M products to be of superior quality. I do like this product, but have some reservations. In regard to performance, it DOES work! I used it for an application other than an automobile, which is also other than its intended purpose.

I have a small work/storage room in my basement. It has slab floor, drywall, and is narrow, less than 5' wide. I have a backup sump pump in the room, which has a control module which manages the backup pump's battery, etc. The module has always produced an electrical buzz/hum, which can be quite annoying when in the room. The module is in the corner of the workroom on a small cabinet, so it is about 5" from a wall on two sides of it. The walls both have pegboard, and in the past I tried fixing some Styrofoam to board by the module. This served only to slightly amplify the buzz.

So I decided to try this product. For my application, I mounted some 1/8" thick wood that I had from a packing crate on the pegboard. I did this, so I would not damage the pegboard with the 3M mats. The mat gripped well, but like anything else of an adhesive nature, you want to measure right and work slowly, as adjusting it afterward is not really an option. Once you have peeled the paper and applied it, it is on fairly well. You could get it off, but would likely wreck it in the process. As far as sizing it, cutting this is like cutting other dense, adhesive type materials. A sharp blade with firm, steady strokes is best. The blade will get a little gummy so plan on changing it out or cleaning it afterward.

Vine Customer Review of Free Product ( What's this? )
I will start off by saying that my SUV is not your average SUV. I drive an old, loud, steel military vehicle that does not have the luxuries of carpeting and air conditioning (but it did come with a rife rack!), so unlike most people, I did not have to pull up carpeting or dismantle my SUV's interior to apply the mat.

It is a very small mat. Make sure that you measure precisely how much you will need for the job because I can guarantee you one pack will not be enough. Also, unless you have experience with working on cars, I feel this is too complicated a project for the average person, and you might end up regretting beginning a project that you have no idea how to finish. If you don't have carpeting like me, though, it's easy.

I decided to put this in the floorboard of the passenger seat. It was simple since all I had to do was follow the instructions and clean the area, then apply the mat. Normally, when I drive my steel tank, I have to yell over the noise if I want to talk to somebody that is in the car with me, but the mat.... did not make a difference. Honestly, with such a small amount, I was not expecting it to. Maybe if I covered the vehicle in in this stuff, it would work. It is nice to be able to put my purse and things on a mat, instead of straight on the floor, and it did seem to help the vibrations a little on that side.

This is a challenging do-it-yourself project for people that have cars with carpeting. If you think you are up to it, then be sure to buy enough material for the project and make sure you have enough time to work on it and see it through. You don't want to have to go to work with your car's interior dismantled because you ran out of time, and you also do not want to be forced to take it to a car mechanic to finish the job because you overestimated your skills.

This is one of those "common sense" products that people forget common sense when using. The ideal use is when installing speakers in your doors or deck. More powerful speakers bring out every vibration in your vehicle and can sound tinny. Applying a sound deadening material when installing speakers is pretty much a requirement. This box has enough for two larger oval, or three smaller round speakers. It will help reduce vibration and slightly "flatten" the sound. If you have a noisy trunk - especially in the wheel wells, this will also help deaden the sound - but you'll probably need two boxes.

This is a SMALL quantity of material. 1.76 x 1.76 feet. Cut a piece of paper that size - it's not that much. If you need to deaden sound in a small problem area, it will work. Consider it a "small project" size. Anyone expecting to make a $15,000 car sound like a $60,000 car by adding sound deadening is dreaming. You'd have to strip the car of almost all the interior, door panels, dash, etc. to apply the stuff - hardly a practical solution, or anything 99.999% of the population could do!

Application: The instructions show using scissors - I prefer a utility knife with a piece of scrap wood as a cutting surface. This stuff looks and feels like a mixture of tar and rubber, and leaves a gummy residue on the scissors. You can clean this off with solvent, or as most guys do, with gas (I don't smoke.) I'd rather just throw away a 10 cent blade.

1) For oddball shapes or curved areas, make a paper template and cut that to shape. Put that on top of the mat as a template and cut.
2) Clean the application area with rubbing alcohol and let dry
3) Use a blow dryer on the mat to soften it up - this is by feel, but you want to flexible.
4) peel and apply.
