Reply To: How Much Water Can Paper Take

What I’ve learned is that different papers can take different amounts of water without buckling, heaviest paper buckling the least. You can tape the paper down when it’s dry, some people use a wooden board and staple the paper to it.

If you like to work wet, there is another method where you use a plexiglass sheet as your board. Wet the paper on the back side, using a lot of water, press the paper down on the plexiglass, then wet the front side. The water will stick the paper to the surface, and it stays wet for much longer. Here’s a video.
