Fabric finish help: spot that didn't stick

Hi guys,

Looks like I didn't use enough glue, and a small spot in between the bridge route and the end of the body didn't stick. At this point, I'm not looking for perfection, so I'm hoping I can just clear coat over it and move on with my life.

Will it just get worse over time or crack the clear? If so, should I try to lance the area and get some glue underneath to stick it down?

Here's the progress so far:

Re: Fabric finish help: spot that didn't stick

I've done several fabric finishes and have had to do minor touchups on each one after gluing. What has worked best has been to take a very sharp Xacto or razor blade, cut a small slit, and inject Super Glue in through the slit or hole. It can help to have some kind of very thin spreader to help reach in to the furthest point where the existing glue failed to bind. Then press and hold with painter's tape until dry. Because the slit is very clean, it's impossible to detect below the clear coat.

I don't think you should just clear coat over it and hope for the best. You'll have some flex there, and sooner or later it will crack and likely separate even more. Try what I suggested on an inconspicuous spot or a test piece, and I think you'll see that it works pretty well.

Looks great by the way!

Re: Fabric finish help: spot that didn't stick

Thanks! I'll give it a try tonight.

When I was wet sanding it last night, the water seemed to "melt" the Modge Podge glue a bit, and I was able to force the area down a bit, but it still doesn't feel quite right. Super glue should do the trick if I can get it to the right spot.

Re: Fabric finish help: spot that didn't stick

I've always used wood glue, so I'm not familiar with Modge Podge. With wood glue, the reason for using Super Glue (rather than more wood glue) for the touchup is that wood glue is great for raw wood but not so good in layering onto itself. It needs some kind of porous surface for proper adhesion. Super Glue seems to bond to almost anything so it's happy if there's already a layer of glue on the two surfaces.

Re: Fabric finish help: spot that didn't stick

cardinal,

Sorry, no recommendations as I haven't done a fabric finish yet, but seeing that you're not that far from me, may I ask where you got the fabric? I'm getting ready for a fabric finish but couldn't find anything nearly as nice as what you've got there.

Re: Fabric finish help: spot that didn't stick

Thanks! Modge Podge is essentially Elmer's white glue from what I can tell. Super glue sticks to it real well (I've used superglue on top of it already to harden the edges for sanding).

I had the fabric made for me through Zazzle.com. I also haven't been impressed with what I could find readily available.

Thanks! I'll take a look at zazzle.

Zazzle will print whatever you want into some fabric.

Re: Fabric finish help: spot that didn't stick

If you haven't fixed it already, a steam iron on medium setting works very well to seal/stick areas that didn't previously bond well. Use some wax paper between the iron and your fabric.

Some times fabrics that have not been washed have trouble bonding. I think it's because of whatever "dry cleaning" chemicals the manufacturers use.

Re: Fabric finish help: spot that didn't stick

Thanks guys! Used a sharp razor to cut through the middle of the problem area, which turned out to be larger than I thought. But the super glue stuck it back down and did a pretty good job filling the cut too.

Good for you man..... it's a nice feeling when you can bring a project back up to speed.

So what are you going to use to fill the texture of the fabric? I used sanding sealer, but it took MONTHS to harden enough to prep for clear.

Re: Fabric finish help: spot that didn't stick

The Modge Podge somewhat filled the texture. After wet sanding with 400 and buffing with 0000 steel wool, it's not too bad. I'm just going to go over it with automotive catalized clear coat and hopefully can wet sand smooth.

Re: Fabric finish help: spot that didn't stick

I always used sanding sealer too. I found that 3-4 applications, with very light sanding between coats and more serious sanding at the end, worked well. Otherwise the natural texture in the fabric was still there and it took way too many coats of clear before I could get it smooth.

RGT -- that's strange that your sanding sealer wouldn't harden. That stuff is supposed to harden within hours. I expect you had a chemical reaction between your sealer and whatever adhesive you used to glue the fabric. I had that problem when I tried to use contact cement -- it didn't like sanding sealer at all.

Re: Fabric finish help: spot that didn't stick

What specific sanding sealer did you guys use and did you paint with laquer or urethane?

Re: Fabric finish help: spot that didn't stick

I've used both Parks and Minwax sanding sealers. I couldn't really tell the difference, but a woodworking shop nearby recommended the Parks product.

I clearcoated with urethane. That worked fine, but I think next time (if there is one) I'll probably drop it off at an auto body shop to have them shoot the clear.
