Hi Pirate, It is self adhesive with a sticky back. I applied two layers thinking it would produce a deeper profile. This second layer released from the first in the presence of the resin. Horizontal sections that lifted were 'weighted' with strips of wood having PVC electrical tape applied to them as a release. The weight was to stop that section's wood strip from sliding off, it wasn't necessary to hold the tape down. Vertical areas were rolled repeatedly once the resin began to gel and increased it 'sticky' factor. Took several hours last night but passed my time on FB, Photobucket etc. Next time I will experiment further with just one layer, that layer did not lift.
PS. Still working on your instructions to get the image into the blog, chuffed I can insert a link!

Tortured ply is clearly beautiful.
