When you say pressure you mean like putting boards with weights on top to dry it?
This was an old bow that had taken set and was close to being retired and I wanted to experiment on it.
1.) First I covered the belly and handle with painters tape.
2.) Then I covered the back with a coat of glue.
3.) Next I put the paper layers on.They were strips cut from a feed bag liner. I had soaked the paper in some water before hand, and squeegeed the excess off as I went.
4.) Between each layer I applied another coating of glue.
5.) Then I laid a coat of plastic wrap over the final paper/glue layer, and added a long 3/8" thick strip of wood over that.
6.) With the tips held up on blocks, I clamped the handle down towards the table to make reflex. Then I applied a whole bunch of clamps so the strip of wood sandwiched and pressed the paper backing down tight against the bow.
7.) I let it dry for a few days, then filed off all the excess paper and coated it with some BLO.
Looking back, probably 2 layers would have been plenty, but I wanted to see what it would do. It initially added about 3 lbs to the draw weight, but it was not noticeable in the arrow speed. The string follow came back after about 100 shots.
The glue-saturated paper coating is a really rugged. I can't attest to how it prevents splinters because I wasnt putting it on a bow that had any splintering issues. It has a nice coffee-like finish, like brown masonite board.
