Hello Everyone!
I just want to know if you can repair molds. I have a mold that I =
would absolutely die if it were to become unusable, at least I need to =
use it a couple more times. It has cracked, but it could easily be glued =
back together. Is this possible? Do they make some special mending =
material for this purpose? Even if it is temporary, that would be o.k.. =
Thanks,
Rachel

I have used yellow carpenters glue to repair molds. It was what I had
on hand at the time. I've used some of these molds over a hundred times
with no sign of them coming apart or any absorption problems. These were
15 to 25 lb molds that had broken in half.
Sometimes it helps to not over think a solution to a problem.

Dear Rachel,

If you just need to use it a couple more times you can repair it with
cyanoacrylate glue for porous materials (like loctite super glue if this
product is available in your country). This glue can bond wet materials as
plaster. The main thing in this repair is to apply the glue punctually with
no continuous layer, in order to facilitate the water absorption by the
plaster. This repair is temporary but it will give you the possibility to
use again your cracked mold.

Cordialement, Denis

Dear Rachel,
If no one comes up with a valid technique to accomplish what you are
trying to do, get in touch with me.
I'm sure I can devise a way if one is not known.
Best regards,

Rachel, I've repaired many cracks amd broken off pieces in molds. Be
sure the mold is absolutely dry. Maybe even have it sit in the oven for
the day at 100-150 degrees to be sure you do not have any entrained
atmospheric moisture in the mold. Apply an adhesive to both sides ot be
bonded. Press together and hold untill next day or maybe a couple of
days with straps or sit something on the mold.

The adhesive of choice is Elmers white glue. Next is Elmers yellow
carpenter's glue. Upi can also use Bordons, pet, or Carnation condensed
canned milk. Allow a few days to set. The casein in the milk does the
bonding and does the holding like nobody's business. Mill may stink
after some use.

Good luck.
