I am currently trying to decide how to fasten down my foam and track. I have heard that that a tube of PL300 lasts a long time. How long can you keep a tube open before it dries up? Also, if you use latex caulk (what kind?), how long does a tube last before drying?
I have an open tube of PL300 that has been sitting under my table for about 6 months and it is still good. I usually clean out the tip and insert a nail or foil over it for a seal. Sometimes a film will develop but you can puncture it and it works just fine.
I do not know about PL300, but I use Liquid Nails for Projects. I opened the current tube about two months ago, when finished I put a screw in the opening and it is still useable. It has been in the upper 90’s plus, during the day here. We do have AC but I keep it around 83.

Wrap the open tube end with a peice of duct tape and it’ll last forever. Don’t use masking or any other tape, they tend to " breathe" and plug the end hard.
Hope this helps.

I inserted a drywall screw, wrapped the end in Saran Wrap, secured that with a rubber band. I u sed the tube off and on for well over a year.
Any brand of inexpensive latex caulk seems to work for me. Some folks have favorite brands, I look for what is on sale.
I usually let the caulk set overnight after getting the pieces positioned as I want them. I do other things around on the layout, as it has a relatively strong hold right off.
Good luck,
Richard
I use either duct tape or a nail. If the stuff at the end of the tube hardens on you, use the little metal probe on the glue gun to clear it. I’ve had tubes of adhesive live for many years before using them up.
I keep the little plastic tip I cut off. I then stick it back in upside down and put a piece of painters tape over it to hold it. Caulk, glue, mortar or anything else that comes in gun tube has been fine for a very long time when I do this.

Have you considered acrylic latex caulk? It’s cheaper and holds just as well. Plus, you don’t have to worry about it attacking foam. An added benefit is that it’s pretty easy to remove track that’s held in place with it.
Loctite polyseamseal all-putpose adhesive caulk. Wrap it in saran wrap and it will keep for a few weeks. Now that I am finished with road bed and track laying and dont have to use a caulking gun, I have a 5 oz squeeze tube that has a replaceable cap over the tip and it is still good 3 months later.
Does anyone besides me use Elmers wood glue to glue down their cork roadbed to the plywood?
My entire layout has white glue holding the cork to the plywood. I use it generously, spread it evenly and pin it with notice-board pins for about 20 minutes. If you should really want to move the cork, it can be pried up with a putty knife or other slim tool. The cork will not survive the removal, but can make decent talus at the cliff bottoms. A bit of scratching will sort of clean the plywood. I tried Liquid Nails but didn’t get the job I wanted, so went back to old reliable white stuff.
