I need to make some "stamps" tomorrow to use to mark the street for an upcoming bike ride.
The person who made the previous set of stamps said he used silicone sealer if I remember correctly. I saw another set elsewhere that had been done with what looks like wood glue or Gorilla glue, but they are brand new so no way to know how durable that solution is.
The sponges will be cut in to shapes/letters to make the stamps, and will be dipped in (impregnated with) exterior latex and plopped on the asphalt-- the sponge needs to really stick to the plywood. Have done it this way for years and the marking method is not in question.
Unfortunately they also will not have more than 4-5 hours to cure (had been counting on another person to take care of this)
Thanks for any opinions.

"liquid nails" adhesive?
you need something that will get into the sponge, and not be brittle.

I agree, Liguid Nails. I used a sponge to wipe some up once and set the sponge on some cardboard. The sponge adhered very well. I know it will bond the heck out of plywood as well. Just remember you don't need a lot. Like most adhesives, less is more- people tend to over do it. Considering your desire for a shortened cure time I would read the label on the Liquid Nails to make sure it is ok. Keep it in a warm, dry area with moving air to speed the curing time if you need to.

They should both have decent set times and be reasonably waterproof as well as solvent-resistant, but beware one very significant difference that Liquid nails is resin-based while Gorilla Glue is a polyurethane. Both should be used in a ventilated area, but that's especially important with Liquid Nails.
I suspect that Gorilla Glue's foaming action might give it a slight advantage adhering sponge and wood, but Liquid Nails would have the edge in drying/curing time.

how about a big staple gun through the middle

Contact cement. I'd use the solvent based one for max adhesion.

Thanks, everyone.
I've decided to forego the time investment of a home depot trip, so to an extent this will depend on what my local Ace has to offer.
I guess I don't know the difference between contact cement and the other things.
jdc, I was thinking of a few staples for each. You got me to thinking that it probably wouldn't hurt to bring the staple gun along (although stapling midstream would be messy). Not too excited about the resultant deformity to the sponge though . . .
Leaning towards Liquid Nails if I can find it. What's the closest "generic" to that, if my LHS doesn't carry that brand?

Not sure what a similar generic would be but ask them and they should be able to tell you. I should have mentioned that Liguid Nails is a brand name and that they sell a bunch of products. Most of the products are sold in caulk gun format which I am assuming you don't have. There is one main product sold as a construction ashesive that is commonly referred to as just "Liquid Nails". You need to look for a small toothpaste like tube of the stuff that is labeled for use in small/home projects. You might want to do some reasearch on the cure time of this stuff before you use it.
If time is really crunched they try an epoxy. The advantage of epoxies is that you don't have to wait long for them to set.

if you don't know Jack, get to know Jack about this one..., he's right on, a proper solvent based contact adhesive is hopefully available at your local Ace.
good luck, hope the ride is awesome.
