Aim: To quieten tyre noise

Required:
Wax and grease remover
Brush on sound deadener (4L drum is heaps enough to do all 4 wheels)
paint brush
srcubbing brush
plenty of rags
jack and car stands

Steps:

jack the car up. make sure the weight is held up by stands not the jack.

remove wheel.


there will be years of dirt and tar etc built up one the arch. this will all need to be cleaned off with a good scrub and wax and grease remover.


once the bulk crap is of and you see the paint give the paint a wipe with a clean rag and wax an grease remover to remove all the residue.



then cover your brakes and suspension with rags to stop any drips from falling on them and paint away. start with a thin coat and build it up as thick as possible. a layer 3-4mm is easily obtained.


do the areas of the arch that are between you and the cabin. no use deadening the engine firewall etc.


Other comments:
This difference was instantly noticeable! almost no tyre noise! definately worth the 40 bucks for the deadener!

'Brush on deadener' is this available at repco/bunnings?

Are there better brands than others?

I'd doubt you'd need it for your E class Stu

You can also do the same thing with spray on, for a similar effect. Its just a little easier IMO.

Nice write up anyways mate.

have you noticed much difference with road noise?

haha you can never have enough deadening! or you can never have enough silence? i checked my wheel arches the other day and it looks like they already have some sort of thick black stuff on it that might be deadener... or dirt.

i thought mine had something on it too! turned out to be dirt lol got it back to all paint. Super cheap sell a brush on deadener for 40 something bucks. this is what i used

i don't think the brand etc would really matter cos its all about adding weight to that panel which they all do. this stuff takes a long time to dry so wait a week before applying the next coat. i will be doing another coat whenever i get time down the track. the spray stuff is just easier the paint on is more cost effective and more effective cos thicker coats can be painted on.

the difference made was instantly noticeable and for you guys that know my car and all the dynamat etc in it for something as simple as this to make a noticeable difference it would be unreal in a stock car (not big luxury boats that alread have heaps). a definate must do for those wanting a quieter ride!

hmm, i wonder if this stuff would be too thick for a spray gun

sound off make a spray gun one

Does this mean no driving for a week?

no it sticks still no worries driving but if you press it it is still soft and as id feels tho the inside is still goey. wait till it is completey hard before reapplying another coat. i drove the car less than a hour after doing it. in my old ek i did it then that day i drove in rain. it still stuck but had water rippled effect on it. it doesn't take long for the air exposed surface to dry and create and skin over the still goey centre. once the skin is formed tho it takes a long time, week plus for really thick parts, to become hard.

i will be doing another coat for over kills sake. i've went overkill everywhere else with it so far but am thankful!

Very nice write up! Definately will be trying this. I'll probably be doing the VS and my bro's EK. As you might know, EK's (civics in general) are a moon away from quite There isn't deadener anywhere yet except flashtac on the number plate and some on the boot lid.

you can get spray guns for bitumen paint - they go on flee bay for about $10+ p&h

or if your mechanic is also a panel beaters work shop like mine - just get them to apply it when tis on the hoist

Did the civics boot and all wheel wells today. Now sound is coming from underneath and the firewall

Sounds like a uni break job.
Will deff give this a go when i get time.

Cheers

would this be suitable to do other parts of the car too, ie. doors, floor, boot lid etc, coz im guessing this would be a lot cheaper than dynamat or similar, also how would this compare to decent matting in terms of sound?

Would be good if we could. i would probably do the boot aswell.

this stuff in comparision to the matted stuff like dynamat etc is just as good but alot harded and messier to apply. what deadens the panels is weight, so per weight it is just as good but i would prefer the mats. Deadener makes the panel more weighted therefore has more inertia and harder to vibrate, is more solid. in addition to this, the tar based deadener absorbs the sound energy and turns it into heat.

i would avoid using this stuff inside the car as it STINKS for weeks.

i would recommend for in the boot you do what i did

my boot

paint the boot with PLENTY of deadener. whilst wet carefully cut pieces of the fleece matting to shapes to cover the boot completely. give the matt a good squish down. and it will be stuck!

Enjoy!

cool, i think il be doing the boot this long weekend so il head down to supercheap and grab a big can of that deadener to go in while im there...

It's commonly thought that adding weight is the only thing about a sound deadener that helps reduce noise.
It's also wrong.
Dynamat extreme ways much LESS Than most bitumen based deadeners, but dampens much BETTER.

also if you want to reduce road noise
use the felt stuff also
name has left my head

actually i believe theres some new products out, air cell foam with a solid layer on top very much like dynamat. Theory being the air cell seperates the floor pan from the solid stuff, so it doesn't vibrate so much as reflect the noise. Cheap too.

I did my rear wheel arches the other day. They're open to the "cabin" of this small 2 seat hatchback, and the front arches are in the engine bay so I didn't do them.

It made a big difference. Even driving slowly on grass the difference in noise was obvious on the first drive. I really wasn't expecting such great results. On the road it was much much better. Previously the majority of the road noise came from the rear of the car but now it's all at the front (firewall, floor, doors).

Like people have said before, sound proofing never ends, once you stop one noise you notice another.

Quid
where did you find this out??
sounds interesting

This seems to be a good, rather cheap and easy step to reduce road noise.
Good post!

found what looks like the patent, still trying to find actual product.

haven't found much feedback yet though, but the theory is interesting.
