How to stretch Water Colour Paper or Recycled Board

This is a very simple process that I was taught at art collage for stretching water colour paper. I have found that the same process works for stretching the board that I sometimes use for collages. No more annoying wrinkles or warping!

You will need
Gummed tape
Large wooden board bigger than the piece of greyboard/paper you wish to stretch
It needs to be non-porous, I used a piece of hardwood that has been varnished.
Board or Paper


  1. This is best done over a sink or bath but can be done on a worktop with a bowl of water.
  2. Thoroughly wet the surface of the wooden board using the sponge.
  3. Wet one side of the greyboard and place, wet side down on the wet wooden board.
  4. Now you need to wet the other side of the greyboard, work quickly to avoid warping.
  5. Use a damp sponge to wet the gummed tape, placing a length along each edge. You can rip these to size before you start to save time.
  6. Not strictly necessary but I add an additional piece across each corner.
  7. Go over the tape and greyboard with the sponge again making sure any air pockets are removed.
  8. Place somewhere warm and dry. I usually leave this overnight before beginning to collage.
