Loose carpet on cabin firewall behind front seats

Yes and yes!

 

I paid someone to restore the interior of my car and for the most part he did an excellent job. After a few months, however, the carpet behind the seat began to sag and eventually started flopping around.

I tried several times to repair it myself, but the adhesive always failed after a week or so.

Finally took it to another trim shop and they managed to get it right.

 

I'm pretty sure they removed the carpet, cleaned off the existing adhesive and reinstalled it with the same 3M trim adhesive that I had been using.

I'm a friends with the owner of the shop that got it right, so I'll call him tomorrow and confirm and let you know.

 

Spoke with the trim guy this morning. He said they removed the carpet and sprayed it and the firewall with 3M Super 77 . He also said it's imperative to apply the carpet and remove it to create a "web" then reapply the carpet.

I asked if they had to remove the old adhesive and he said no.

I don't remember for sure, but I'm almost positive I was using a different 3M adhesive with my failed attempts.

I hope this helps.

 

Good Luck!

 

Good luck!

Unfortunately, and with very few miles since the last attempt, mine is loose again.

I'm beginning to think that the original interior guy may have cut the carpet too short.

I'll post a pic later today.

 

Taking back when the weather cooperates.

The carpet should be removed and steamed to flatten the crease. Then use this to glue it back in.

Thanks

Can anyone tell from my picture if the carpet appears to be too short?

I'm wondering if the shelf is designed to help hold the carpet in place.

 

Yes, this is correct. Use 3M 8090. 3M 77 is a crafts glue, not at all suitable for upholstery or carpet and not rated for the high temps an interior will see on a sunny day.

 

Thanks again, guys.

I'm still thinking the carpet was cut short.

In any event, I'll pick up a can of the recommended adhesive and have them try again.

 

Damn.

I don't know if I can buy just that section.

 

It's black alcantara. Trim guy talked me into it.

It looks a little purplish in that photo, but looks better, and more black in person.

 

I just fixed mine using DAP Weldwood brush on contact cement. I only applied the cement along the top edge of the carpet (about two inches) and along the lip under the shelf. I slathered on very thick layers, let the glue set up to tacky then the carpet virtually "welds" itself to the top of the firewall. I think the spray on stuff works great for flat, non-porous surfaces but cannot fill the voids in the carpet nap like the thick brush on stuff does. Even if you feel your carpet is a little short I think this would work because, from what I see, the shelf does not in any way serve as a support for this. the carpet just lays under it and is not secured by it.

 

Thanks Paul

Can you tell me approximately how much carpet goes under the shelf?
