Cork

Anyone have a good, and successful, idea on how to flatten a roll of cork?

After I cut sheet cork for the area I wanted, 24” x 114” I laid it out on the bench and put 4-1”x4” boards on it and then a bunch of 12 pack cans of soda, my bags of ballast and basically every can out of the pantry. Left it for 3 nights and it was fine. I was told to first spritz some water on the flat sheet but I never did that. Good luck.

I rolled it out upside down so the roll was turned down and weighted it and sprayed it with water and let it dry and then glued it down with Elmers Carpenter Glue onto the plywood.  That was five years ago.  Track and Scenery is done on top of it.  No problems at all.    Doug

I unwrap it and lay it out with some weights to hold it down as best as possible as has been described, but this is never completely successful as there is always some residual curl. When it comes time to install the cork I spread white glue evenly on the area that will receive the cork, lay out the cork, then place a piece of 3/4" plywood big enough to cover the entire cork sheet on top and drive in a handful of screws through the top plywood and into the roadbed. Let the glue dry for a few hours, remove the screws and plywood and the cork should be fully glued and flat with only a few unnoticeable screw holes.

I don't bother. I apply a layer of Loctite Power Grab to the subroadbed, then press the cork into it. As long as you're quick about it (Power Grab doesn't have a very long open time), any curl in the cork is inconsequential.

Hell you could even do it with white glue if you make sure you pin everything down while it dries.

Yellow carpenter’s glue (and thumbtacks until dry) for me.

Same here, although I make sure the curl is facing down, otherwise the edges like to pull up slightly while the glue sets.

I attached my with Latex Contact Cement applied with a small paint roller.

Thanks for all of the suggestions, gentlemen.  I have a lot to choose from

A bit late to the party, but in addition to weighting, then securing with your favorite material (I used Weldwood Contact Cement, the non smelly kind if you can find it....) I also recommend that you use a roller from the center out to flatten it.  Going from the center out in all directions keeps you from accidentally pushing a fold into the cork that you don't want, as you are always pushing to an edge, not a perhaps sticky too early middle section.

Non smelly,,,no such thing in your train room..lol
I second DKS, powergrab is good. They even make it in clear, so you can lay track with it.
Contact cement is good also,,just follow the directions.
