I usually like to mount paper on board before I start painting as this allows me to stretch it in the process of mounting it.
This time I had a few already painted watercolors on paper that I thought would look good once mounted on board and varnished. Here are the steps I took:
The first step is to find a board that is the same size of the painting. For some of the watercolors I had to order some custom sized boards as they were not fitting into the standard sizes or I would have had to cut too much of the painting to make it fit. Now I am going to give more though to the size of what I paint before to make sure it will fit standard sizes.
Then I did trim the sides of the painting to make it easier to place on the board for the next steps.
I am spreading heavy body gel medium with a stiff brush all over the board, paying specific attention to the sides and the corners of the board.
Heavy body gel medium is better than the liquid kind because the paper won’t get too wet and that reduces the risks of the paper buckling.
I am then centering the painting on the board being very careful that no medium goes on top of the painting.
Then I am using a brayer roll to evenly fix the paper to the board and to remove potential air bubbles. I am also being very careful that the brayer stays clean and that no medium goes on top of the painting.
I am leaving the painting to dry overnight. I added some weight in each corner to make sure they won’t lift while drying. ( In case you are wondering the paper weights are big river rocks that I did cover with crochet)
The next day everything has dried, now I need to trim the excess paper on the sides.
I am using a cutter to do so.
If the sides are not straight enough after trimming, I sometimes use a sander to finish them. Next step will be fixing the watercolor and varnishing it. I will detail that process in another post.
