In today's tutorial, I'm going to give you some tips on removing masking fluid and next time we'll look at some of the alternate approaches to masking -- including unusual uses of the fluid and use of masking films. (If you want to review the first posts in this series, go back here and here!!)
Before removing the masking fluid, it's a good idea to clean off as much of the residual paint on the surface of the masking as possible so you don't rub dried paint onto your paper as you work. You can use a damp tissue for the larger areas and a damp cotton swab for smaller places.
In the image above, I'm removing a section of masking fluid with a rubber cement pickup -- basically a little square of crepe shoe sole material. I rub it lightly at the edge of the masked area to grab the masking and pull gently away from the paper. This works especially well with Winsor Newton masking fluid because it forms a relatively thin film. With the heavier masking fluids such as Incredible White Mask and Pebeo, you can start lifting the film with the pickup and then pull on it with your fingers to remove it in strips or sheets (this also works with the Winsor Newton). Below, you see me pulling the masking off by hand after getting each row started with the pickup tool. I carefully grab the rolled edge left by the pickup and tug gently.
If you have very small areas of masking fluid, such as the dots I used on this painting, you can either rub over them gently with the pickup tool or use your fingers to loosen them. You must clean the edge of the pickup or wipe your fingers frequently so you don't smear paint onto the newly uncovered areas as you work. I find it helps greatly to brush the surface afterwards with a drafting brush to remove all the loose bits. That won't mar your paint surface or rub paint into the reserved areas.
At the end of this process, you need to "pat down" the painting to make sure you've removed all the masking fluid. Run your hands lightly across the surface to detect any missed spots.
In my last tutorial, I mentioned that I had read that you shouldn't shake the bottle of masking fluid because it causes the latex to clump, but I couldn't recall where I'd found that information. Reader Kristen Colebank pointed out that Elizabeth Kincaid discusses this in her book Paint Watercolors that Dance with Light (North Light Books). Although I only recently purchased a copy of Elizabeth's book, I suspect that I may have looked through it at some point and that it was the source I remembered. Thanks, Kristen!!
I hope you're enjoying these posts. I recently saw a comment from an artist asking why we artists spend so much time on technique instead of talking about ideas. I've been thinking about that ever since and have to answer that without a solid grounding in technique, all the fabulous ideas in the world are just elusive mists. The goal is to reach a point where the technique becomes so integrated into your process that it becomes second nature. I hope I'm helping you proceed in that direction!!
