Leather glue

I use good fashion contact cement. I don't think the brand name really matters much. What I have found that bests works for me and gives me the best holding is to apply one coat on the flesh (fuzzy) side of the pieces, let dry then add a second coat until dry (about 10 -15 minutes), mate the two pieces, use a roller to evenly press the pieces together, clamp or weight down the pieces and let sit for 12-24 hours.

My theory is the first coat of contact cement sinks into the fibres and binds them together. The second coat holds both surfaces permanently together. I have found sometimes with only one coat of contact cement the two pieces can be pulled apart.

I do that as well, but one thing I do differently is that I keep two jars of contact cement, one of which is slightly thinner than the other. The thinner is for the first coat. I also work in  a good tooth on the leather. The first coat must be dry; then apply the second coat. then I press and hammer together. The only contact cement I use is Bardge cement and thinner. I have never had a separation. Bardge contact is as strong as it gets.

I've been using a heat gun to "activate" contact cement - just a brief warming of the glued pieces before assembly.  Bonds well with less cement so I have fewer problems with the glue interfering with burnishing edges.  For some shaped pieces I case the leather lightly and shape the leather before applying the glue, and the heat gun treatment results in a better bond when the leather is damp.  I'm using Barge cement but will probably switch to Weldwood in the future.

OK?

So are you guys popping the lid on wildwood glue each time you use it or are you transferring the glue to a different container and using a different type of applicator?  I've been using barge quart cans with the applicator and a pair of channel lock pliers to get it open every time I need it. Is their a different more convenient method?

I replace the lid after I finish gluing an item. I also tap the lid around the edges with a mallet.

Used to do a lot of plastic laminate work. Bought the contact cement in five gallon buckets.

Also: I used latex contact cement on laminate, only use solvent based on leather.

yea, i have a smaller glass weldwood bottle with a brush that I transfer to. You can also replenish the acetone as needed if it starts drying up. i usually put a bit in the can after opening it or transferring.

I refill a Barge quart can from a gallon can, adding Barge thinner as needed.  Made a funnel from a 16 oz plastic bottle.

What is everyone's favorite glue pot?

I use a contact adhesive all the time

For small areas or seams I use a tube glue called UHU. For larger areas I use a brand none of youse would have heard of. I work straight from the 1 litre tin. Sometimes I pour in a wee bit of Evostick adhesive cleaner which acts as a thinner too and it stops the glue going 'off'

I rarely wait for the glue to go tacky. One generous coat of glue on one of the item parts then I stick the items together and clamp up. After a couple of hours I remove the clamps and tap down with a small rubber-head mallet

Never had a problem doing it this way and 99.9999% of the time I get a good glue bond
