Stretching paper and backing board

February 21st, 2008 | Category: Art supplies and equipment, Painting techniques

I always use a backing board when I am painting. A backing board is a board to which you will tape the watercolour paper so it will need to be larger all the way round than the paper.

The size of the board will depend on the size of your painting - it can be made from hardboard, masonite, plywood or any such wood. When I paint I tend to use quite a lot of water, for my washes, which is a technique called wet-into-wet. Watercolour paper tends to buckle, especially if you use a light weight paper and this is why I recommend using 300 gsm (the grammage or weight of the paper is now universally measured in grams per square metre).

If you are using a light weight paper, however, you will need stretch the paper. The best way to do this is to soak the paper overnight in a bath of water, hold the paper upright to let most of the water run off, then tape or even staple to the board. The paper will shrink; but when dries it will pull tight, which will make it durable and workable.
