Two Must Try Watercolor Techniques


Two Must Try Watercolor Techniques

Maia and I combined our two favorite watercolor techniques last week during Daphne’s naptime.

Watercolor resist and salt.

Watercolor resist is one of our all-time favorite techniques to use with watercolors.

We’ve tried lots of variations, including ::

This time we revisited the rubber cement resist and then sprinkled salt on the wet watercolors. Adding salt is something we like to do with any paint at times, but it really creates beautiful effects with watercolors.

Here’s how we did it…

Liquid watercolor paints

First, we drizzled designs and pictures with the rubber cement onto a sheet of poster board as well as some smaller pieces of watercolor paper. I didn’t take any photos of this step; sorry. I guess I was too busy drizzling.

A note about rubber cement :: Use it in a well ventilated area or do it outside. The fumes are not the best to breathe. There are no fumes once it is dry.

We let the rubber cement dry overnight and during the next day’s nap, painted over the rubber cement designs with liquid watercolors.

Then, we sprinkled salt over the wet watercolor paint. Maia was very into this step and would have been even more generous with the salt if we had had more in the house. As it was, she used the last of it.

Note: This works best if the salt is sprinkled over very wet watercolors, so do it quickly before the paper absorbs the watercolor paint.

Maia continued painting sections and adding salt, painting sections and adding salt. She was doing this on the big posterboard, remember. When we did the smaller pieces on the 9×12″ watercolor paper, we didn’t have to do it in sections.

Here she is, with a paintbrush in one hand and salt in the other. The smaller pieces we did are laying flat on the floor in the background. We didn’t want to hang them on the drying wall for fear the salt would slide off and the watercolors would drip off.

Once the watercolor resist painting was finished, we let it dry completely.

Two Watercolor Painting Techniques - before removing the rubber cement and salt

Here’s a section of the dry painting with the salt and rubber cement still on it. See how the salt creates interesting designs in the paint? The salt crystals soak up the liquid from the watercolor paint, creating areas without as much pigment.

To vary the effect, you can use different size salt crystals as well as try it with more or less watercolor paint (ie more or less wet). We mostly used table salt this time, with a little bit of sea salt, but have used the coarser kosher salt as well in the past.

Now, here’s a close up of the rubber cement lines. I wanted to show you this, because in the next photos, the rubber cement will have been rubbed off, exposing the bright white paper underneath.

To finish the artwork, we first brushed and rubbed the salt off the painting as much as possible with our hands.

Removing rubber cement from watercolor painting

Then, we used our fingers to rub the rubber cement off the paper. It balls up and comes off as you rub it. It took a while, and because of the salt that was still left on the paper, it wasn’t gentle on our fingers. We shared the task and kept alternating our fingers and thumbs.

I would recommend starting with smaller artworks. If you want to do a large posterboard-size artwork, then consider spreading the rubber cement removal task over 2-3 days, doing a little bit at a time.

But look! It is so beautiful! We kept exclaiming over how it looked the whole time we were rubbing off the rubber cement. And afterward.

I just love the combination of the vibrant liquid watercolors, the drizzled white lines from the rubber cement resist, and the mottled texture from the salt. LOVE it.

Here’s the big picture. We hung it up in a place of honor in the living room.

Our smaller artworks are hanging on the drying wall, waiting until we’re ready to rub off some more rubber cement. Soon!

As art activities go, this one was a big hit. The combination of the two watercolor techniques made for a fun process and a beautiful finished product.

    This is way too fun, Jean! The effect reminds me of batik. I’m feeling a little trapped creatively since we’ve been on vacation, and can’t wait to do more experimentation like this when we get home.

    Just a reminder to California followers that we are not allowed to use rubber cement with children in a classroom setting. They banned its use a couple of years ago. Sad, but true. I guess I will have to try white or clear glue and not remove it.

    I use this process in my professional watercolors, but repeat it. After the paint dries, remove some of the cement, then add more cement, let dry, paint some more, dry, remove some cement, add some more repeat. Do this layering over and over until you are done, then do a final “peel.” I use watercolor resist (much more expensive than cement) and 300lb paper and it does not lift up the watercolor pigment or tear the paper (but the painting must be completely dry before adding more glue). I think you might try it and see how you like the extra layers, though I don’t know how rubber cement would work…but it would be worth a try! (sorry if this got posted twice…)

    Thanks, Rachelle! Do you have a sketchbook with you? I imagine there’s a lot you can do on a small scale (if you have the time, that is. I know you have a lot going on).

    The white or clear glue might work but you’d want to make sure it dries before adding the salt and watercolors or you’ll end up with salty watercolors ( – another of our favorites. You could also just do a watercolor resist with white crayon or white oil pastel and then add the salt element to that. Also, I’ve used something called masking fluid in art classes myself that works similarly to the rubber cement. I wonder how kid-friendly it is? I haven’t tried it with kids but it’s worth looking into…

    This looks so fun! And the end result is stunning too! I also wouldn’t use the rubber cement because it gives me an immediate headache :( but am going to try with the blue glue as you did on this project:
    And the layering idea is fantastic!

    Beautiful beautiful! It reminds me of the batik with glue we did this summer, but the colors are much more vibrant. Now I need to know where can I find rubber cement in Spain :-)

    Oh, I’d love to try this with multiple layers and I’m sure Maia would too! How fun!

    Let me know how it works with the blue glue. Have you tried using rubber cement outside?

    Would this technique work on a smaller blank canvas?

    Its lovely. Would it work if you used white glue instead of rubber cement?

    these were gorgeous!! I love how you said you put the painting in a “place of honor”. So, when you said you used posterboard, did you mean a glossy “oaktag” paper?? I’ve done the masking fluid and the salt many times, but alsways used a high count watercolor paper…

    Jean, this is really spectacular. I’m so far behind on reading and keeping up with things these past couple of weeks but I wanted to let you know that we are trying this for sure! (Also, loved the plaster flowers and the interview, just way behind on everything.)

    Hello Jean,
    I just discovered your delightful – so many wonderful ideas to share with my grandchildren. But, I must tell you, as a professional artist just rediscovering watercolors, this article has been amazingly inspiring. I can’t wait to get back into the studio to work . . . oops, scratch that . . . PLAY!
    Thanks so much for sharing and for the wonderful step by step descriptions and photographs.

    Each year I have a tea party for my four grand-daughters. For the next one I thought i would call it an Art-tea party. I was looking for ideas using some kind of resist technique and came across your watercolor resist with salt. I think they would really enjoy doing this.I wondered how you got the rubber cement thin enough to drizzel? Would it work on a gessoed board?

    Hello would this technique work well on canvases too?

    This is really. Will try this with my daughter’s birthday party in January. I was looking for ideas and I think I can easily do this at home. i am sure girls are going to have fun.
    I just came across a website called Artbeez where one can showcase, sell kids art work and raise money for charity all together. Thought of sharing this.

    Ok seriously…absolutely gorgeous no matter who made them! This technique basically makes all pieces real works of art that I believe my LO could benefit from! ! ! We have yet to try any type of Salt Watercolor Painting, this looks amazing! Rubber Cement who knew?! Not me! I kept humming n hawing at it the other day at Walmart, now I wish I picked it up: tomorrow I will be! We already have some medium sized Neon Colored Poster Paper! I’m SOO excited! I know my LO still likes to use hands when painting at times, the added salt might be just what she needs to be interested in Watercolor Painting. She still hasn’t figured out Less Water MORE swirling brush on paint before drawing as yet; & so she doesn’t truly appreciate the joys of Watercolors. This may be up her alley– Thank You so much for sharing your expertise ;D

    I must have missed this art lesson when I was a kid. But I’m loving it now
