Carpet Glue

[johnman001]

What is the best glue to use when gluing in new carpets?

I am working on a 1974 911 that is being upgraded with many new parts. The interior is getting a new set of carpets and I need to start gluing in the new carpet set.

If anyone has advice as to which pieces to start with and some order that the carpets should be installed and what type/brand of glue is best to use, I would be most appreciative.

I laid out all the carpet pieces and it looks as if I should start with the two outer sided pieces that extend along the rocker panels back to under the rear seats, but there are also the pieces in front of the doors and I was wondering if those actually are installed first.

All opinions and advice is welcome.

Thank you in advance. I will be posting some pictures of this project as I am working on it.

RWebb,

Thanks for your attempt, but your link was to a dead page. I will try a search, but in the mean time, any and all suggestions are welcome.

Thank you

odd - it worked for me the 1st time but not now

anyway, I just searched on carpet glue

Use one of the 3M aerosol products rated for Hi-Strength / Hi-Heat and it's hard to go wrong. There's been of couple of threads on here in the past few months that dealt with the issue, and what I wrote above pretty much covers the general concensus of opinion. There's going to be a few locations that mandate a brush-on application, most notably where the various floor mat pieces overlap the side panel pieces which were previously installed. For these, I personally advocate the gel-type of contact cement that DAP/Weldwood produces, available at your basic home improvement stores. As to where to start, I found that back to front worked well for me, keeping in mind which pieces were lapped over others when you stripped out the old stuff. Hopefully you took photos as you removed the old, they're an invaluable reference when going in the reverse order to install the new.

Two hints, particularly if you're using the spray adhesive: have plenty of tape and masking paper (newspaper will do) to shield off areas in the tub where you'd just as soon not goop up until necessary. Dry fitting the new piece and doing a chalk outline is helpful, then masking up to to it (with some fudge factor). Secondly, take care not to oversaturate the back side of the carpet pieces (whether spraying or brushing). The solvents in the adhesive tend to bleed through the backing and can cause matting of the pile. Finally, if you're catastrophizing over all the things that can and might go wrong, don't. Just note where your old pieces might have darts cut to facilitate forming, and dive in. When you're done you're going to stand back and mutter to yourself, "Dang, looks pretty good!".

dap/weldwood are the best in my opinion...go to many upholstery shops and while they use a spray gun (water based stuff is junk in my opinion) its the old non water-soluble stuff.
apply in a well ventilated area.

Thanks. These are the types of responses I am looking for.

Unfortunately, I did not remove the old carpet set and I don't have pictures of the progression. However, a search here did lead me to a few threads that show what appears to be a reasonable sequence. In addition, my full size 3-D model (stock 930) will help me figure out how the various pieces do go together. I'll look for 3m adhesive, but I'm mostly familiar with the type used for gluing vinyl, and I don't think that stuff is meant for carpet.


Thanks for the replies and keep them coming.

When I installed my new carpet set I used what Stodd%^&d called automotive trim adhesive. It comes in a quart can. It looked like contact cement. It worked great. Just have your doors open and don't smoke.

John, I just replaced my carpet and deleted the rear seats. I scraped out the old adheasive and promised not to repeat that mess. I used very little adhesive only at places where necessary. You can fit the carpet under the interior step panel on the sides and under the consol so the only place you really have to glue is in the rear (not very much) and front kick panels.

I used a non toxic universal adhesive from Weldbond that works great and won't give off fumes. It is cheap and easy to use and bonds like iron! The original Porsche glue was everywhere and it was not as good as Weldbond.

I did get some of the 3M '74' Foam Fast ordered from McMaster Carr and that should be here in a couple of days. I also picked up some 3M '77' locally as well as a pint of the Weldwood gel contact cement. The supplier of the carpet suggested that he only uses the 3M '77' and the 3M '99' in the pedal area. I really like the idea of marking out the outlines of each piece so it's easy to see where to apply the glue, and I like the suggestions to work a small area at a time in order to get it right.

Thanks for all the suggestions.

Sorry, there is a poster from NY that has a similar screen name......he has a iconic sales ad for a wheel.

Thought it was the same guy....my bad.

don't bother with the super77. it is a great general purpose glue but it has a very low resistance to heat and will not hold up to the inside temps of a car. i ran out of 74 with one door pocket left and tried the 77 only to have the carpet fall off. the super90 has better resistance but i only used the 74 and was very happy with the results.

anyone using the more typical adhesives should carefully read the MSDS first

a particle mask will be no help, and you will need a quality vapor mask (canister mask)

even then skin absorption will occur

you will need to think about how much liver damage you will get - there WILL be some

the availability of a non-toxic glue (post 13) is a great thing - DG624, can I ask how long you carpet pieces have been in?

[DG624]

You don't need any mask or ventilation if you use the Weldbond glue and it sticks better than anything in wet or dry. The carpet has been in for over a year in the 911 and for two years in my VW GTI. This Welbond is very good and you don't need an aerosol. Just a reasonable amount on the carpet back at only the places it may come lose or not stay in place. I just glued it at the bottom of the rear section and the side pieces. I used a reasonable amount on the front kick panel pieces. The best part is that you will not smell it after you are done our for years while driving your car. Less expensive than the 3M type glues and you can use for any household project also.

thx - it sounds good
