I have a front driver seat from a 2005 Dodge Ram with power lumbar. The end of the lumbar support (not the mechanism) seems to wear a hole through the foam. The power lumbar seems rare, and every one I have seen has the same issue. I'm thinking of just repairing the foam. What foam should I use to replace the worn area, and what kind of glue should I use to fuse it to the rest of the molded foam area? I have an electric knife and some gorilla glue...

thanks!

@fj5gtx

are you working at a shop taking seats out to see all these? I just seen Gorilla glue is paray cans and would be sure it would have foam to foam bonding. With the tools you have and the health of the foam I would just cut a nice hole in that foam tunnell shaped, cut your foam to match and glue it in. Try to adhere some thick fabric under that foam where it is getting rubbed too!

-I would use this glue. Weldwood Landau Top Contact Adhesive: https://amzn.to/2nwDBO5
- Cut out the damaged area and glue in an over sized chunk of foam
-Cut the foam to match the shape.
-You can also use a angle grinder with a 3inch 60grit pad to shape the foam nicely
-Then glue some muslin over the repair to make it a little stronger

Do a quick search on this forum for "Foam Repair" there is a few other threads with information on this that will hopefully help.

No, just a general restoration enthusiast that spends way too much time in jyards and auctions. I was going to wrap the plastic mount I circled in red with something to take the sharpness out. Not sure why its made like that, perhaps the shape and edges are intentional in the design. I have used foam from another seat, thinking that one will end up being the donor of foam for this seat back. The gorilla glue I have says foam adhesive on the jar, and its just brush on type.

I've looked at that glue before, I can't imagine needing more than a couple table spoons and I've not found it in anything less than 1 gallon containers. What is the shelf life after opened? I don't do much interior repairs, maybe once a year.... last was a 06 mustang door panel - 3M spray trim adhesive didn't last, gorilla glue on there for months w/o fail yet...

Thanks for the input, I have watched some youtube videos, I picked up some ideas.

@fj5gtx Then I would try permitex headliner adhesive. https://amzn.to/2Lob09D
I have had weldwood over 3 years old and it still works. Sometimes you need to add a little acetone to thin it out when it gets old.

Just getting back to this job. Figured I'd share... I couldn't find the Dap adhesive locally, and it was over $50 mailorder... then I happened to call grainger, and they'll have it Monday for about $34 plus tax. Travelling next week, but will probably start working that foam week after next.

Thanks for the advice.

Good luck on your repair, remember to glue both surfaces so they want to stick to each other like velcro and bond!

[fj5gtx]

I have a couple places where the foam has split apart - but it looks like its in fine shape. Can I just stuff some glue down in the split? Or do I need to do something more invasive?

Also, can I just spread the weldwood with a brush? This small repair doesn't seem to really warrant the spray gun, unless the glue isn't viable unless sprayed.

Thanks!

I have seen some videos where they glued the split then backed it with a patch of fabric glued on both sides. Personally I wouldn’t do it on a big split but a minor one should be ok.

[BigRig]

@fj5gtx , I am with Revv on this one. Big splits casue a loss of foam density and you end up with a sagging cushion on one side. It looks like it will hold the weight but wont.

[John]

If the foam is not old and crusty you can glue it back together and glue a canvas patch over top. You might feel a little difference in density but its a lot easier than replacing the foam.
If the foam is old and crunchy you need to grind out the bad foam and glue in a new section. Or replace all of it.

Another pick up seat. Holes in this foam are from a dog chewing up the seat! Just going about FOAM REPAIR for this puppy.

Repair looks awesome BigRig!

Can you describe your technique and tools you use?

[John]

Nice Job @BigRig !

[BigRig]

@davemac2 ,

First step was picking all the hair out of that chewed up foam. I like to stage my repairs so that the glue has time to cure then really grind into it and pull the foam hard to make sure my foam repair does not fall apart. I used a cheese grater and 80 grit sandpaper by hand for starters.
