There was a thread regarding installation of Pontos wood decks by the companies owner. It's not there any more but I saved it:
How to use Pontos wooden deck...
At first peel off the back film from the wooden deck.
Be careful in touching finger on the adhesive side, this may result in reducing adhension.
And then Spray pure water on the adhesive side of woodendeck and surface of palstic kit deck.
and carefully apply wooden deck on the surface of plastic deck.
Water make in possible in adjusting the location easily as water sliding decal.
after fitting is finished remove water as water sliding decal.
You can use hot air (with as warm hair drier) for drying the water.
After some days or weeks there may be peeled off area, in this case you can fix slightly with instant glue for this.
Thank you
