Re: Glue results part 1

Robert Doubleday

There seems to be a wide range of approaches to trying to glue materials which are subjected to a variety of chemical compositions. The general consensus was to strip off the base sole, glue the sub-sole to the shoe base, and sew the welt to the sub-sole. Then neutralize the material with several different types of chemicals, so that I can use the standard glue to finish the shoe modifications. I have listed each of the responses to follow. Thank each of you for your responses and expertise. Once more I thank Paul and his staff for the forum. I am putting each of these list serve messages since the onset into a data base search engine for my future use and possibly for use by those who follow in my footsteps.

We typically use Duall 88 as our primary source for glue. It works very
well if you will let it dry completely prior to putting any heat to the
material itself. A couple of layers never hurts as well. You can also
try using a primer of whatever adhesive you plan on using mixed 50% with
acetone. Making sure all surfaces are cleaned and roughed up a bit.
Another thing to consider if using a polyurethane sole is Gorilla glue.
It is designed for such surfaces that have oil-based design. Regarding
the Gorilla glue, you cannot neglect the directions. It requires the
mist of water to help set off. Just a thought…hope this helps and look
forward to the other ideas you receive.

Hi Rob,
I have had problems with certain materials not sticking as well.
Not exactly what you described but our solution may help. My
technician discovered it. Before applying super bond (from
knit Rite, better than Barge) he applies super glue thinly to
both surfaces and lets it dry. Then he glues as usual with
Super Bond.
Good Luck,
Hope this helps,
Rob Biaggi C.P.O.

Hi Robert, Try covering both surfaces with SUPER Glue. Let
it dry completely, then coat both surfaces with Barge or Dual
88. When they are at the proper amount of drying time put
them together as usual. This should hold.

My opinion is that moisture is getting in between the layers or the glue
just isn’t adhering well.

Once you split the sole, sand both surfaces to even them out and remove
loose debris.

Then wipe with rubbing alcohol.

If the material is other than crepe like, such as pvc, you need to spread a
thin layer of super glue over the areas to be bonded and let dry or spray
with a catalyst to speed the drying.

I use Masters Multipurpose glue and let set till almost non tacky, then heat
with heat gun lightly to get tacky and apply material together and use
rubber mallet to pound sole on stand.

Probably the most important part: use a thin piece of crepe to wrap the
entire welt/sole boarder to help keep moister out, kind of like doing an out
flare. You are just trying to seal the seams.

I have had to do this on mechanics and hog farmers here in the Midwest.

Hope this helps

Dear Robert,

You are trying to crack a nut that might not be able to be cracked. These newer
and less porous soling materials do not respond to glue as did the leather and crepe
on former shoes and boots. I think there is a heat process in their manufacture that
can’t be duplicated by conventional shoe repair methods. I suggest that you get a
boot with the long wearing soles your patient needs such as Brahma, Redwing, etc
and then glue your lateral heel and sole wedges inside the shoe. Good luck.

Sincerely,
Ron LeFors, C.P.O.

Apply thin layer of superglue to both surfaces several times, rough up the
super glue after it has cured and apply your regular glues to the roughed up
superglue surface as usual. The superglue acts as an interface between to
surfaces your traditional glues don’t want to bond to.

Good afternoon
For difficult adhering jobs we’ve used acrylic cements -industrial crazy glue.
We purchase it from our local shoe findings person.
Good luck
All the best
