Adhesive for leather and canvas bag

[kjcreamer]

Hello. I'm making a bushcraft type backpack that will have a mix of leather and canvas parts. I made prototype that turned out really well except for the parts that I used barge to attach the leather to the canvas. For example the leather bottom to the canvas bottom and the leather buckle attachment to the canvas front. You can tell the cement "bled" through. My canvas is light/medium weight - sort of like a carhart jacket exterior fabric.I suppose I could just rely on the handstitching of leather to canvas but since this is a pack, I want it as strong as possible. Another option is a different adhesive but won't those others bleed too? (I only have Barge and plain Elmers but I'd be willing to buy something else if there's a suggestion). If it's a water based adhesive, how is it affected if the pack gets wet? I do plan to waterproof the canvas with a hot beeswax, parrafin, and boiled linseed oil mix that I saw online. I'd love any input.

I would try 2-3 very light coats of cement, allowing each coat to dry well before the next coat.

I use 3M High Strength 90 spray glue for that application

Hi Colt. So you think the spray adhesive and handstitching is adequate for the strap tabs on the pack? I estimate I would carry no more than 20lb and would have 12lb weight goal most of the time.
