How to Mount Canvas on Board

I used to mount canvas on board with Frank's PH Fabric Adhesive. I demonstrated how to do it on a previous blog post: Canvas and the Icarus Board: Final PostAlthough this method worked pretty well, the glue would always moisten the canvas which would take a long time to dry before I could varnish it. I finally found a double-stick adhesive that is suitable for rough surfaces like canvas.


Above are my finished canvas and a roll of adhesive on top of a 24" x 48" Claybord.


Gudy 831 is a very aggressive double-stick adhesive especially suitable for application on rough or textured surfaces. It's acid free (pH 7), passed the photo activity test (PAT), and will not dry out or discolor with age. It's available on rolls with a single release liner. Easily applied by hand, it will never dry out or discolor with age. Gudy 831 can be purchased online from Talas in different size rolls.


After carefully unrolling the adhesive onto the surface of the Claybord (sticky side toward the board), I burnished it with a brayer and trimmed the excess around the edges. I punctured the air bubbles with an X-Acto knife and burnished until the air was all gone. 


Here's a close-up of a seam where I had to join two separate sheets of adhesive because the roll wasn't wide enough. Again, I pressed the seam with a burnisher.


This is the canvas ready to be mounted, after I trimmed the white edges. At this point my piece measures 24.5" x 48.5", half an inch larger than the board, to account for possible misalignment during mounting. 


I created a fold on the release liner to expose a 1" wide section of the tacky area.


I positioned the canvas over the board and, when perfectly centered, I pressed down on the canvas over the exposed 1" section of adhesive.


Then I slowly pulled away the release paper while unrolling the canvas over the adhesive. With a sheet of tracing paper covering the canvas, I gently rubbed the surface with a rag until all the release paper was pulled out.


I rolled a rubber brayer all over the surface protected by tracing paper.


I turned the board upside down and trimmed the extra canvas with an X-Acto knife.


To achieve perfect cuts I used a fresh blade for each side of the artwork.


Finally I placed the board under heavy books overnight. Using Gudy 831 allowed me to begin varnishing the day after mounting the canvas.

New Beginnings

Recently I sold the last available original in my rock and water series, "Crescendo". Its new home is in Washington State.

Clearly this series has a wider appeal than my flowers so I will continue with colorful riverbeds. 

The first one of the two artworks I just started is a large commission, a 24" x 48" canvas.

Below you can see a faint outline. I will show only cropped progress images and allow my collector to see the finished work first.

The second artwork I recently started is a medium size canvas, 12" x 24". This riverbed is very intriguing to me; it's moodier and more abstract than my previous ones, showing plenty of water movement and unusual reflections. 

Below you can see a photo of the initial outline and another one with some progress.

Both canvases are primed with Art Spectrum Pastel and Multimedia Primer (Colourfix) and I will be using a combination of Neocolors, oil pastels and colored pencils on the Icarus board.

Stay tuned for progress photos.

 

“Unveiled”

Tools: Tortillions, Paper Stumps and Colour Shapers
Surface: Extra Fine Texture Canvas primed with several coats of clear Art Spectrum Colourfix Supertooth Primer
Technique: Icarus Drawing Board
Presentation: Mounted on a 3/4" Ampersand Claybord, varnished and framed

I'm very proud to have completed this piece, if nothing else for its size alone. It has accompanied me through the trials and triumphs of this past year. It's been a faithful companion even though I neglected it for long spells, at times in favor of other artworks, and later during the long months of my youngest son's illness, surgery and recovery.

It was born out of necessity. I sold its twin brother "In Between", before I had a chance to have it professionally scanned. I had many requests for giclees so I decided to redo it four times its size. Since I was familiar with the subject and technique, I thought I could concentrate on the challenge of working on a much larger scale.
 

Above is the enlarged drawing I used to trace the outline on the canvas with Verithin colored pencils. I like to use local colors to avoid erasing graphite. On this blog post you can see how I traced it.
 

Of course I made some changes along the way. This progress photo shows a large stone on the bottom left corner that I eventually replaced with smaller pebbles. I used an electric eraser to lift most of the pigment and then drew new pebbles on top. 
 

Here I mapped the area with Neocolors and oil pastels. Neocolors are very useful, especially around the edges, because they can be sharpened. Oil pastels come in such a wide selection of colors, I would be limiting my palette if I weren't using them. At this stage I set the temperature of the Icarus board to low. 

 

The photo above shows the results of melting the Neocolors and oil pastels. I normally melt at the highest temperature using a colour shaper. Then I blend further and pick up any extra pigment left on the surface with a paper stump. At this point the Colourfix primer's texture has resurfaced again, making the canvas receptive to colored pencils.
 

Here you can see how I further developed the colors, values and details using colored pencils, with the board set at medium-low temperature. The perfect tools for blending colored pencils are tortillions and paper stumps.
 

When blocking-in, it's not important to include all color nuances and details. These can be developed later with colored pencils. 
 

Melting the pigment is probably the most exciting application of this technique. Again, it's not necessary to create perfectly smooth blending at this stage; that's what colored pencils are for.
 

Above is another example of how I developed the colors, values and details using colored pencils.
 

In this third series of close-ups I’d like to talk about how to speed up the process. Mapping with Neocolors and oil pastels is much quicker than mapping with colored pencil. Some of these rocks can measure up to 12 square inches or more!
 

Melting the waxy pigments is a very effective technique for fast coverage of the canvas surface. It compares to dissolving water-soluble Neocolors with a brush, except there’s no color or value change with heat.
 

Another valuable time-saving technique is adding all the details at the end. Highlights are time consuming if you need to account for them from the beginning. I created all the thin highlights by subtracting the pigment with a Verithin white pencil and by going over with a softer pencil or with a sharp, white Neocolor.
 

In the photo above I’m showing how I devised an easier way to work with a large canvas. I placed a 20” x 20” claybord, 2” thick, along the side of the Icarus board, thus creating a larger surface for the canvas to rest on. 
 

What’s appealing to me about working on canvas versus paper is that I don’t have to worry about creasing or bending it. Canvas is very flexible and can take a lot of abuse.

 

I like to roll up my canvas so that it doesn’t hang over my knees. I use two binder clips to keep the canvas from unrolling.
 

Here is a close-up of the canvas fastened with binder clips.
 

The finished canvas is now taped to a cardboard and ready for spraying.
 

After mounting the canvas on a cradled board, I will then varnish it and frame it.

 

Report on my San Diego Demonstration

I love those San Diegan CPSA chapter members! They always make me feel welcomed and appreciated.

Everyone was very interested in learning how I work with canvas on the Icarus board. When I rolled out my 24" x 48" canvas in progress I could definitely see their curiosity peaking.

Here are the points I discussed during my presentation:

  • why canvas
  • what type of canvas
  • how to prime it
  • how to mount it and varnish it

Afterwards I demonstrated the three main techniques I use when working with canvas on the Icarus board :

  • mapping the main colors with wax pastels (low temperature)
  • melting and thinning wax pastels (high temperature)
  • developing colors, values and details with colored pencils (medium temperature)

I set up three stations, each with a board at a different temperature, so that a line of attendees could swiftly move through the steps and try the different applications. Unfortunately, after I answered all their questions, there wasn't enough time for everybody to try to replicate the techniques. However, I think they all walked away with a sense of new possibilities.

 

Inching Toward the Finish Line

I'm inching toward the finish line and soon I will be done with my largest piece ever. Below is a picture of what I've accomplished so far.

I'm not surprised to have discovered that I enjoy working big. When I used to paint in oil (back in the nineties) my smallest canvas was 30" x 30". It never occurred to me to paint any smaller. That feeling stayed with me even after I transitioned to colored pencil.

The Icarus technique has allowed me to tackle larger work, especially by combining colored pencils with wax crayons (artist crayons) and oil pastels. I'm also realizing that time is not necessarily proportionate to size. 

On my final post I will tell you how I'm able to speed up the process, how I feel about working on canvas, and I will show you some close-ups of the progress. Stay tuned!

Pushing the Limits

Last summer at the Laguna Beach Festival of Arts I had the opportunity to talk to hundreds of visitors and many of them inquired if I had large-scale work available. This rekindled my longstanding desire to create bigger art.

After much experimenting I realized that the best way to accomplish this goal was to find a flexible surface that I could place on top of my Icarus board without damaging it (the surface). I knew that paper was not my best choice because large sheets tend to crease or bend when used on a desk.

I tested various substrates and found that canvas had the flexibility needed for my purpose. I purchased a roll of Caravaggio Extra Fine Double-Primed Cotton Canvas, the finest texture canvas available. Artists who would like to experiment with canvas and the Icarus board for the first time are advised to purchase a portrait-grade stretched canvas, unstaple it from the bars, and then, after the painting is finished, re-stretch it on the same bars.

My first attempt to work large was a 28" x 48" piece, temporarily named The Quarry. I primed the canvas with three coats of Art Spectrum Colourfix Supertooth Primer, clear. This primer helps colored pencil and wax & oil pastel adhere well to the canvas. When I prefer a smoother texture I use the regular Art Spectrum Colourfix Primer, clear instead.

Below you can see the first two passages I accomplished:

First passage: blocking-in

Second passage: melting

Blocking-in detail

Melting detail

As I was getting ready to tackle the third and final passage to develop color, values, and details, I changed my mind about finishing The Quarry and put it temporarily aside.

One of my favorite artwork, In Between (see image below), sold as soon as I posted it on my blog. I had something special planned for that piece!

In Between

For that reason, after asking permission to my collector and changing its size, I decided to re-do it four times as big as the original. If you're interested in this topic of making repeats, I suggest you read Robert Genn's newsletter Identical Twins.

Soon I began working on the 24" x 48" twin of In Between. I'm only about half-way done because other more urgent, smaller pieces are taking precedence.

The strategy I'm following with the 'twin' is different than that of The Quarry. Since it's a re-do, I don't feel the need to block-in the whole composition and colors. As you can see from the image below, I'm completing one stone at a time.

Eventually, as I garner more experience with large sized artwork using the Icarus board, I will share with you all the tips and tricks learned along the way.

The 'twin' halfway done

When I was a little girl my father used to ask me: "Ester, why do you always push the limits?". He was naturally worried! I understand now, because I have a son who's exactly like me.

 

“River Pebbles, No. 11”

River Pebbles, No 11

Title: River Pebbles, No. 11

Outline - Cool Zone

The outline was accomplished with Prismacolor Verithin on the cool zone of the Icarus board.

Color Mapping - Warm Zone - Low Temperature

After drawing the outline I proceeded to map the main colors with Neocolor artist crayons on the warm zone of the Icarus board using a low temperature.

For more on color mapping with artist crayons you can view the following videos:

Melting - Warm Zone - High Temperature

With temperature setting at maximum, I melted the artist crayons using clay shapers (also known as color shapers).

For more on melting artist crayons you can view the following videos:

Tools for Melting Artist Crayons

In the picture above you can see the two color shapers I used for melting and the wet sponge for cleaning. For easier cleaning I spray the surface of the wet sponge with a little Simple Green.

Refining with Colored Pencil - Medium Temperature

With the temperature set at medium I developed the colors, values and details of the pebbles by layering and blending colored pencils with a variety of tools like tortillions, paper stumps and a Caran d'Ache blender.

Mounted on 2" Thick Clayboard

I finally mounted the canvas on a 2" thick Claybord and painted the sides with acrylic. The artwork is now ready for varnishing.
