Can I use solvent-based contact cement on neoprene rubber?

[Phil Thien]

I started a different thread yesterday about a Ryobi S500A finish sander. I want to replace the pad. I found the guys that make the Preppin Weapon (awesome sanding block, BTW) sell the backing material separately here:

They say to use 3M Number 90 Spray Adhesive. I could buy a can ($12 at Home Depot) or instead try to brush on some regular contact (solvent-based) I already have. This stuff:

The TDB for the Weldwood contact cement says it is neoprene-rubber based, but also says it can be used for bonding rubber. This stuff (the Weldwood) won't melt the neoprene rubber, will it?

I'm trying to avoid a giant mess, and also don't want to spend any more money than I have to. I kinda doubt I'd find any other uses for the 3M Number 90, so I'd like to avoid buying $12 worth of spray adhesive and wasting most of it.

Thanks Andrew. I think I'll just call Weldwood in the morning and ask their technical support people. If all else fails, I can test on a little corner and see what happens, too.

I use solvent based contact cement to repair wetsuits. It won't melt the neoprene and it sticks fine.

We use 3M 90 at work and judging by the smell there's plenty of solvent in it. We also use regular solvent based contact cement on open cell, like a wet suit only 3/8 or 1/2 inch thick, and regular neoprene with no issues at all.
