Rubber Boot Repair

[Shotgun]

The sole is separating from the upper on one of my rubber boots. I am looking for recommendations for a rubber cement or maybe an epoxy of some kind to make the repair. Please let me know if you know of a good rubber to rubber adhesive that might work.

If it's actual rubber to rubber, I have had good luck with toluene based rubber cements. I make bicycle tire patches out of old inner tubes, and the tube will tear before the patch pulls free. The toluene free cements don't work nearly as well. I clean the surfaces well, put a thin layer cement on both surfaces, let it dry, put another thin coat on one surface, press them together and clamp them for 24 hours.

If it's rubber on some sort of PVC coated fabric I don't know what will work.

Last time I fixed something like that, I used 3M Super Weatherstrip adhesive (https://www.amazon.com/3M-MMM8001-Weatherstrip-Gasket-Adhesive/dp/B002NXZ7NW/ref=sr_1_2?ie=UTF8&qid=1493481470&sr=8-2&keywords=3m+super+weatherstrip+adhesive), aka monkey snot, applied to both surfaces until tacky then put the shoe in the shop's 100 ton press and let it sit overnight.

ETA: If appearances matter, they also make 3MSWSA in black (https://www.amazon.com/3M-08008-Black-Weatherstrip-Adhesive/dp/B00063X38M/ref=pd_bxgy_263_2?_encoding=UTF8&pd_rd_i=B00063X38M&pd_rd_r=1AM19SJX7NDJBZVBPD3J&pd_rd_w=wDVro&pd_rd_wg=W9h8i&psc=1&refRID=1AM19SJX7NDJBZVBPD3J).

Take a good hard look at E6000.

Ask me how I know

Ask me how I know

I'll bite. How do you know?

Btw, looks like all the rubber cements are toluene free these days. Plus, the separation between the upper and the sole is only about an 1/8 of an inch at this point. It would be hard to use a rubber cement per instructions I think. e6000 is looking like the solution at this point.

I had a sole separate from the heel to almost the toe at the beginning of a shift. I mixed up a tube of B1/2 sealant and used a thick layer to repair the shoe. Of course, I had to stand in my shoe until the sealant cured enough to hold every thing together, but I was working at the bench that night anyway. I've tried other adhesives, but none have done the job as well as the B1/2. The B1/2 held the shoe together for a long time even when exposed to oil, fuel and hydraulic fluid. This sealant has good adhesion, good shear strength and good for filling gaps in faying surfaces. Wear gloves as you're applying it

I reccomend seam-grip it is a product for sealing and repairing tents actually, it comes in a tube like toothpaste. I have used it to successfully repair failing soles when the shoe fitter said nothing would work that was like three years ago it works really well. Clean the area with compressed air, clean with ISO alcohol, then apply the product, clamp as needed, several applications may be necessary to fill the void and then you can layer it on the outside as well. https://www.amazon.com/Gear-Aid-Repair-Adhesive-Sealant/dp/B000OR5PHW/ref=sr_1_1?ie=UTF8&qid=1493648148&sr=8-1&keywords=seam+grip+sealer+and+adhesive
