I chose to use foam as the baseboard of my layout. I started experimenting with this in 2008 (see Details). This actual track on this test rig was only pinned in place as it was never permanent.
Foam is great to lay my Peco code 75 HO flextrack. I can easily pin it in place using ordinary dressmaking pins. But you can't nail it down.
The adhesive I use is LATEX CEMENT and I buy it from carpet suppliers or carpet layers. I take a 1 or 2 litre plastic container and get it filled for say $10 or so.
It needs to be thinned with water to a consistency of milk. I originally thought it would need to be thicker, but the thinner it is the better it penetrated under sleepers etc.
What happens if you change your mind and want to move something? It is actually reasonably easy just by dissolving the dried latex - see below. |
