hey i brought some sound deadner from jaycar does anyone know how to install it? its not the normal one where u heat n stick it, it is like a carpet one extremly heavy black, any suggestions on how to install it?

Spray on adhesive?

Clean both surfaces thoroughly (Prepsol, metho etc.). Spray both surfaces with the adhesive, wait till tacky, then press together. Use a roller to make a better contact.

ok thanx wat adhesive shud i use thers millions at bunnings

bigjohn is talking about spray-on adhesive that you can get in a can. If you don't mind brushing the glue on you could use contact adhesive. Just follow the directions on the back of the tin and you'll be fine.

When it falls off that adhesive is a BIATCH to clean off when you decide to install better SD. Speaking from experience as when i bought my car it was like that.

The black heavy sound deadener that you speak of is really only any good on FLAT surfaces, like the outer door skin. Do not use it on the inner door skin unless it is flat. I have tried it on the inner one and it did next to nothing, but made a considerable difference on the outer one. Personally I wouldn't waste dynamat on the outer doorskin as this is just as good if not better.

I used Gel Grip to stick it down. Don't use Kwik Grip as it is quite liquid and won't stay on vertical surfaces too well. Use a paint brush that you won't need afterward. It stuck alright on the inner skin but I am going to use it on the outer skin this week sometime when I get my Dynamat Bulk Pack.

whats inner and outer skin of a door lol

There's something sus about using a "carpet"
material where there is moisture

Its not carpet - its open cell foam. And the heavy material is Barium impregnated rubber - which is also water resistant.

The outer door skin is the sheet that is outer most on the car. Basically the other side is painted and thats the bit you can see. The inner door skin is the basically the frame of the door on the inside. It has holes and stuff for accessing the mechanisms inside. The door trim is the nice plastic bit you see on the inside of the car.

I would recommend putting the sound deadener on the inside of Outer Door Skin. It will be relatively flat and should withstand the elements well.

Have to agree - don't try the Jaycar HEAVY DUTY SOUND BARRIER DAMPING MATERIAL on uneven surfaces as the material doesn't really flex or expand much. Gel Grip is the way to go as it can be used on vertical or upside down and holds well. Just be careful as it can make a hell of a mess.

I'd have to say that having used the Jaycar stuff and Dynamat Xtreme, it's Dynamat all the way IMHO at $150 for a Door kit. If you use the cheaper stuff you'd spend 4 x $11.25 + $20 for Gel Grip + brush - say $70 which is half price, but a heap of time in cutting, gluing and sticking. If you go the IMPROVED stuff it would be about $100 plus the time factor.

So after the fact and having tried both ways, Dynamat is much easier to apply and moulds to very uneven surfaces. I also have a concern with solvent-based adhesives on painted metal.

That's my opinion but good luck with whatever you decide to do.

Just so you guys know, when i got my car alot of the deadener had fallen completely off - both the inner and outer skin. I dont mean to badmouth any products, but its crap.

Open cell absorbs water, closed cell is water proof.
