    gorilla glue on leather???

    what would happen if i tried to glue leather to like a hard backing what would happen. would the glue seep through it?

    Anything can be built if you have good plans, the right tools, the right know how, and more importently the money to do it.

    RE: gorilla glue on leather???

    The leather, being porous, would absorb a considerable amount of glue. I think maybe the simplest approach would be to spread your polyurethane glue thoroughly on the backing ONLY - then spritz the "glue" (but unglued) side of the leather with a spray bottle of water just enough to dampen the leather SLIGHTLY - not NEARLY enough to tool it. Now clamp the leather firmly in place, using a flat backer across the entire surface of the leather. The poly glue will do all the rest.

    Having spread it on the hard surface first, you'll have assured yourself that the surface is thoroughly wetted with glue. The glue, upon contacting the moisture you just put on the leather, will catalyze very nicely and expand into the leather as it cures.

    Clamp it really well to avoid ending up with bubbles of expanded glue in the middle someplace... and work quickly. You only get one chance at this.

    RE: gorilla glue on leather???

    Depends on what the substrate is....Dampening the leather is a bad idea; doing so will cause it to loose the grain and you stand a very good chance that it (the leather) will discolor.

    Normally, hide glue, dextrin, casein, or shoemaker's paste is used for laying leather. If the substrate is fairly porous, it should be sized first with thinned hide glue.

    If you insist on using Gorilla Glue, run a test piece first spreading it thin on the test piece of substrate then let it set until it starts to tack.

    It's also very important that the substrate is completely free from dust and the glue free from lumps, grit, and air bubbles. Use a stiff brush to apply the glue, pop any air bubbles before it tacks with a pin. Leather is never clamped, a padded weight is used...

    Is the leather to be inset or cover the surface of the piece entirely?
