I've seen y'all use recommend both 3M 74 and 90 for applying Byrne fabric to landau and it looks like you're consistently recommending 74 for applying landau to the plywood. My question is this: is it okay to use either product for applying Byrne to landau? Right now, 74 costs twice as much as 90 and, while I want to use what will hold up best, I wouldn't mind saving a little cash as well. Thanks again for the immensely-helpful videos!
74 is Specifically made for foam and fabric. It will be the best adhesive for the job. We use CA94 in the shop (similar to 90 but not exactly the same) it will work, but not as easily as the 74. The finer mist of glue will be more finicky and react stronger to changes in temp and humidity during application. Ever since Covid has hit, glue supply has been crazy. We use substitutes when needed. The majority of our gluing is now done with 3M fast tack. It’s a water based glue and works well. Requires a gun to apply and dries a little slower. We still use cans for detail work like in vans
I imagine that you also have an outside and an inside curve. Can you show how to upholstery both an outside and an inside curve at the same time or one where you you have both at the same time
Does Marathon Tweed/Duramax have a pattern direction? How careful do you need to cut it out? Should you line up the panels to go in one fabric direction with the panel tops aligned the same way? I'm asking because when you upholster with other fabrics then aligning the pattern is important. Is Marathon Tweed so easy to use that this doesn't matter?
i'm guessing you haven't had any problems with the adhesive adhering long term. i heard some reports that a compressor and spray gun was necessary because of the heat in a vehicle. do you know if the 74 and 90 are both water soluble (making panels out of XPS)? TIA
It’s all dependent on the glue you use. We’ve used a lot of things over the years, but each glue we use now has a purpose. Id say correct application is most important and keeping in mind the substrates you are gluing. (Material type and porosity) In the case of XPS the 74 is the best. If you apply too closely the propellant will melt the foam, but the glue does not. Neither 74 nor 90 are water soluble. 90 will melt XPS though. Compressor vs can (even the big cans we use, 26 lb ers) is mostly a cost/setup and cleaning decision. These days it’s also subject to availability. 3M didn’t have little cans for a long time, and they still have limited availability.
We never have but if you’re in an extremely wet climate it wouldn’t hurt to seal them in. I’d be curious to hear what other folks do with their builds.
I have a dog and the last thing I would want, is fabric on the walls that would collect hair. Could you use a faux leather (vinyl) fabric instead? That would be much easier to clean, right?
You can absolutely do vinyl walls. We have in the past. I just don’t like the look. Everyone has their needs. I’d try to find a stretch vinyl that will make some of these wraps easier.
Super demo. Nice neat application! Looks terrific!
Thank you! Cheers!
Excellent. Great job, thanks.
Glad you liked it!
Excellent. Thanks
Sweet!

Why glue & not stretch & staple? Thanks.
Very nice video, very usefull !
Normally, what thickness did you use for the foam and the wood?
.25 wall panels .125 landau foam. All available on our website. Avcrig.com
Thanks
😎
I imagine that you also have an outside and an inside curve. Can you show how to upholstery both an outside and an inside curve at the same time or one where you you have both at the same time
Sure thing, we’ve got this video and it shows you how to upholster for curves in windows. Hopefully it helps!

The pattern is more if a weave than an actual pattern. As long as you put it on straight it’s fine.
Thanks for the detailed instructions. What exactly is landau do you have a link to what you use?
It’s 1/8 landau and we sell it on our web store
Is there any advantage to doing each panel vs putting all the panels on the van and then upholstering them??

I was wondering the same thing. I’d heard of adhesion issues but that could be improper application. 🤷♂️

@@AVCRIG thanks man!
Is there any reason you would need to treat the exposed wood on the back side of the panel? Or is it good to go as is?
We never have but if you’re in an extremely wet climate it wouldn’t hurt to seal them in. I’d be curious to hear what other folks do with their builds.

Please tell us the cure time for each spray. I cannot find them anywhere!
What color was this fabric?
Do you screw the panel to the van wall? If so do you drill a hole first?
We use self tapping screws to install.
Which thickens landau do you use, 1/8 or 1/4 inch? Thanks
We used 1/8” landau.
