Which adhesive for reglueing floor mat carpeting and backing pad? - PeachParts Mercedes-Benz Forum

5cylinder · #1 06-17-2020, 12:08 PM

Greetings good M-B people.

Recently, I have had the original front and rear floor mats (carpeting + backing pad) out of my 1985 300D. After 35 years, the adhesive securing one to the other has weakened (see attached picture for an example).

Searching the archives here, I have found the following 3 potential adhesive candidates for reglueing the carpeting and backing pads:
1. Weldwood Contact Cement
2. E6000 Industrial Adhesive
3. 3M Super 77
I've also considered using Liquid Nails Small Projects & Repairs Adhesive.

If anyone has experience with the above products, positive or negative, I would appreciate your sharing the results. Also, if anyone has another product to recommend for this work, I would appreciate reading about that, too.

Thank you-

A little over 2 years ago now, I used E6000 on my front mats because the original glue had disintegrated. It was easy to apply and so far, everything is still held together pretty good.

Though I haven't used this in precisely your application it sticks phenomenally, durable, flexible and cheaper per volume than E6000. Just read the reviews.
Also it does not stink - a plus inside the car.

Nice. I had not seen this particular Liquid Nails product. Looks like an excellent option. Thanks for pointing me to this.

I have 06 W211 on which the floor mats have foam backing and has foam dried out and it is no longer keeping the mats from sliding. I was wondering if I could spray FlexSeal or something thing else to restore them. Hate to spend $$$ on a new set.

3M 77 is more of an arts and crafts type adhesive. For auto applications I use 3M 90 adhesive (green can). It is most like the commercial contact cement upholstery shops use.

I heartily agree...3M 90 (green can) automotive spray adhesive is excellent. I’ve used it very successfully on foam hood pads and headliners.

First, I'm sorry to read this.
Second, can you elaborate a bit on what happened with using the dap?

Thanks ROLLGUY and Jay Gibbs for letting me know about 3M 90 and your positive experiences with it. Given that you've both used it, I do have this question about the variable-width spray pattern nozzle on the can:

Was the nozzle able to produce a fairly narrow pattern and not just blast adhesive spray all over?

As you can see from the example picture that I attached, my need is reglueing fairly narrow areas where the adhesive has aged to the point of giving out. So, so to speak, I'm seeking to kind of "tuck-in" those relatively small areas - mostly round the perimeter of the mats. This was why I had originally figured that I would have to use something more along the lines of a glue from a tube.

Any thoughts?

Thanks again-

Yes, as far as I remember. I have always used it with the widest nozzle setting, but I am pretty sure the narrower setting is what you are looking for.
