Gluing vinyl to vinyl

[MinUph]

What have you guys and gals found that will glue vinyl double welt to itself? We found a hot glue that will do it but it is $1000.00 minimum. Don't need that kind of investment. I have tried a brush on I think it 66 or something that work on one sample but not another sample. I don't like the look of stapling dw on so I need to find a glue that will do the job.

Good question. Like you, I've found that ordinary glue sticks work well on some vinyls, but not others. I recently did a DW job out of recycled leather, and my regular glue sticks worked great. But on more petroleum-based vinyls, you can just pull the DW off with a gentle tug.

Would you post a link to the $1K minimum stuff that you found? I'd like to at least know what it is I'm looking for.

The 66 vinyl to vinyl stuff has been around a long time and worked on some automotive stuff in the past but it sure disfigured the vinyl.  So, I don't use it anymore, have little need for it on convertible tops and such anyway.

For marine, we use the premade hidem and staple. as you would know.

For furniture, don't know what I would do, except look for something that works for marine or?

I use high temperature contact adhesive, solvent type.

I think I can safely say we have all had situations like this. I once resorted to Super Glue with good success.

With the contact adhesive, how do apply this product. I'm assuming you buy it in quart cans.

I wouldn't think that contact adhesive would be practical for applying double welt, unless you can feed a narrow line of it through a nozzle.

Besides, with most contact cements, you apply the product to both surfaces, and then put them together. It would be tedious to try to apply adhesive to the back of the DW.

TEdious is better than failure :). I have been searching and read about a product from loctite. Comes in a tube. I picked up one to try on Monday. Will keep you all informed. Keep the ideas coming.

This may be the time to go back to using gimp tacks?

I've used hot melt glue before. When it works it works really well. I've also used staples after hot melt glue because the hot melt glue was easy to pull off. Staples were very difficult to keep everything looking smooth and level with vinyl.

I've pulled out those 1/4" wide staples, but I've never used them. I wonder if they would work as well as gimp tacks? It would take a new gun and I wouldn't use it enough to really want to buy one.

The 1/4" (AKA narrow crown) stapler that I have uses 18 ga wire, the same as my brad nailer vs. the 22 or 23 ga. for upholstery staples.  I think they'd be a lot more conspicuous.   I use NCS for putting 1/4" panels on the back of cabinets, going through multiple layers of leather on the bottom of recliner footrests, assembling boxes, etc.

[sofadoc]

The narrow crown staple works great for anchoring double welt at corner turns. The bend in the welt serves to hide the staple perfectly. But on long straight runs, every staple would leave a noticeable "dip". You have to have some form of adhesive for long runs between turns. And like Paul points out, some vinyls just don't adhere well with hot glue sticks.

The stuff that Bob T linked will probably do a great job. But applying it will be tedious. It doesn't tack instantly like hot glue. But like Paul says, "Tedious" might be his only option on this particular job.

HH 66 was made to glue / weld vinyls together.

Hi Mike,
  I know it is made to weld but it doesn't bite some vinyls I have tested. Do you have anything that works?

What's wrong with a cheap artist's paintbrush? That's what I use for applying it. Five minutes, whilst you do something else and it can be just pressed together.

Contact adhesive doesn't work on this stuff. If peels off like water.
Haven't tried the laundue (sp) mix yet.
  I found a product called vinyl to vinyl adhesive made by permatex and it works fairly well. This product works on one of the two jobs we have going. The other vinyl works better with the 66 stuff. This vinyl to vinyl from permatex doesn't work at all on this other vinyl.
  Which makes me realize there are reasons for this DUH. Some will actually work with hot glue some with one type of adhesive and not others. There must be a way to get this down pat so I don't have to experiment with each type of vinyl.
