Dcflyn Posted February 18, 2014 Report Posted February 18, 2014 I'm beginning some upholstery work on the E. I've taken the interior cover off the luggage hatch, removed the old fabric and foam, and applied new foam and vinyl. I'm using a 3M spray adhesive for the large flat areas and DAP contact cement for the overlap areas around the back of the piece. (Sorry, no photos yet.) I'm concerned that I'm using the wrong glue and/or foam for effectiveness and durability...or am I just not applying enough spray adhesive and letting it cure long enough? It's a concave piece and has pulled away already. Any suggestions? Thanks, David http://n2690w.blogspot.com/
PLN_FXR Posted February 19, 2014 Report Posted February 19, 2014 3M makes several different spray adhesives, if you're using one specifically for the materials it should be ok. However ... I have found many of the spray adhesives will release when they get hot, and sunshine/Texas/summer heat would certainly apply for you. I'd guess in your case you didn't allow the adhesive to cure adequately before joining the parts; another issue is allowing the foam adhesive to totally cure (for a day or more) prior to applying the vinyl, as the vinyl will prevent the adhesive beneath from gassing/curing. Good luck!
isaacpr7 Posted February 19, 2014 Report Posted February 19, 2014 The local upholstery shop helping me with my interiors recommended that I use a hight temp glue that they use at their shop for that type of job. This type of glue comes in a gallon for about 30 bucks (I have seen spray cans of the same version on ebay) and can only be sprayed with an automotive spray gun. The shop owner tells me that this gallon lasts him over a year. His tip was to spray a few thin coats, allowin each coat to become tacky and use a vinyl brand called Allante. This vinyl has a type of backing that when used with the aforementioned glue, it will not create any gases under hot weather conditions; therefore, it will not delaminate. On the panels that are upholstered using 1/4" foam, he only applied glue to the portion that overlaps in the back and reinforced the overlap with staples. He does not apply glue to the front side so that if the piece is worked into place by bending, it will not create wrinkles from what I understand.
Dcflyn Posted February 19, 2014 Author Report Posted February 19, 2014 Nice tips. Thank you, all. Will report back when I'm further along.
